I saw the corpus clock strike ahead

It was about time too!

my effort of an image of the corpus clock.
My own little photo of the Corpus Clock.

Because I’d read about it. Though I cannot explain it, I found some where, some one, that can…

It’s the Corpus Time Eater. Blink and you will miss it.

The Mechanics of the clock…

The Corpus Clock is a product of traditional mechanical clockmaking. It features the world’s largest grasshopper escapement, a low-friction mechanism for converting
pendulum motion into rotational motion while at the same time giving back to the pendulum the energy needed to maintain its swing.

The grasshopper escapement was an invention of the renowned eighteenth-century clockmaker John Harrison, and Taylor intended the Corpus Clock to be a homage to Harrison’s work.

Since “no one knows how a grasshopper escapement works”, Taylor “decided to turn the clock inside out” so that the escapement, and the escape wheel it turns, would be his clock’s defining feature.


Time going haywired

“The gold eyelids travel across the eye and disappear again in an instant; if you are not watching carefully you will not even notice…

Sometimes you will even see two blinks in quick succession. The Blink is performed by a hidden spring drive, controlled in the best tradition of seventeenth century clockmakers of London. The spring is coiled up inside a housing that can be seen mounted on the large gearwheel visibly protruding from the bottom of the mechanism. As the huge pendulum below the Clock rocks the Chronophage as he steps round the great escapewheel, each backward and forward movement is used by sprag clutches to wind up the drive spring. A position step prevents the spring from being overwound yet allows the spring to be ready at an instant to drive the Blink. The mechanism is released by a countwheel with semi random spacing so the Blink takes place at any position in the to- and fro- motion of the pendulum. A further countwheel mechanism chooses a single or a double blink whilst the air damper at the top of the gear train slows the action to a realistic pace.”

Giant Molecular Clouding is GMC

A vast assemblage of molecular gas with a mass of approximately 103 to 107 times the mass of the Sun is called a giant molecular cloud (GMC).


GMCs are around 15 to 600 light-years in diameter (5 to 200 parsecs). Whereas the average density in the solar vicinity is one particle per cubic centimetre, the average density of a GMC is a hundred to a thousand times as great.

Although the Sun is much more dense than a GMC, the volume of a GMC is so great that it contains much more mass than the Sun.

The substructure of a GMC is a complex pattern of filaments, sheets, bubbles, and irregular clumps.




GMCs are so large that “local” ones can cover a significant fraction of a constellation; thus they are often referred to by the name of that constellation, e.g. the Orion Molecular Cloud (OMC) or the Taurus Molecular Cloud (TMC). These local GMCs are arrayed in a ring in the neighborhood of the Sun coinciding with the Gould Belt.
The most massive collection of molecular clouds in the galaxy forms an asymmetrical ring about the galactic center at a radius of 120 parsecs; the largest component of this ring is the Sagittarius B2 complex. The Sagittarius region is chemically rich and is often used as an exemplar by astronomers searching for new molecules in
interstellar space.







July belongs to Jupiter

‘We conquered Jupiter’ – July 2016

Juno Spacecraft and Instruments

The Juno spacecraft launched aboard an Atlas V-551 rocket from Cape Canaveral, Fla., on Aug. 5, 2011, and will reach Jupiter in July 2016. The spacecraft will orbit Jupiter 32 times, skimming to within 3,100 miles (5,000 kilometers) above the planet’s cloud tops, for approximately one year.

Juno uses a spinning solar-powered spacecraft in a highly elliptical polar orbit that avoids most of Jupiter’s high radiation regions. The designs of the individual instruments are straightforward and the mission does not require the development of any new technologies.

the galileo hubble sight non collision

They met on the Milky Way

Before Galileo, it was thought that all bright objects in the sky were either the planets in the Solar System, moons, comets, or stars. Until the beginning of the twentieth century, astronomers did not know the size of the Universe, but speculated it to be about as big as the Milky Way.

In 1920, at the National Academy of Science, there was a big debate between Harlow Shapley and Heber D. Curtis on whether nebulae are small globular clusters surrounding the Milky Way, or separate galaxies located farther away. Nothing was resolved at the debate; neither side was able to provide conclusive evidence to prove their side correct over their opponent.

In 1923, Edwin Hubble resolved the matter with a photograph that he took of the Andromeda Galaxy. What he found in his photograph was a very bright light source pulsing at a certain rate, a Cepheid variable, located outside the Milky Way. This can be used to determine the distance to it.

Hubble proved that the Universe was full of galaxies, and disproved that the Milky Way was the extent of the Universe. There are many types of galaxies in the Universe, elliptical, barred spiral galaxies; they vary in shape and size, but on average spiral galaxies are the most abundant.




Caldwell 44 barred spiral galaxy

NGC 7479 (also known as Caldwell 44) is a barred spiral galaxy about 105 million light-years away in the constellation Pegasus. It was discovered by William Herschel in 1784. Supernovae SN 1990U and SN 2009jf occurred in NGC 7479. NGC 7479 is also recognized as a Seyfert galaxy and a Liner undergoing starburst activity not only on the nucleus and the outer arms, but also across the bar of the galaxy, where most of the stars were formed in the last 100 million years.

Polarization studies of this galaxy indicate that it recently underwent a minor merger and that it is unique in the radio continuum, with arms opening in a direction opposite to the optical arms. This feature, along with the asymmetrical arms of the galaxy and the intense star formation activity are attributed to a merger with a smaller galaxy.

Schrodinger Equation and Quantum Mechanics

‘Schrödinger’s equation’

In quantum mechanics, the Schrödinger equation is a partial differential equation that describes how the quantum state of a quantum system changes with time. It was formulated in late 1925, and published in 1926, by the Austrian physicist Erwin Schrödinger.


In classical mechanics Newton’s second law, (F = ma), is used to mathematically predict what a given system will do at any time after a known initial condition. In quantum mechanics, the analogue of Newton’s law is Schrödinger’s equation for a quantum system (usually atoms, molecules, and subatomic particles whether free, bound, or localized). It is not a simple algebraic equation, but in general a linearpartial differential equation, describing the time-evolution of the system’s wave function (also called a “state function”).

The concept of a wavefunction is a fundamental postulate of quantum mechanics. Although Schrödinger’s equation is often presented as a separate postulate, some authors show that some properties resulting from Schrödinger’s equation may be deduced just from symmetry principles alone, for example the commutation relations. Generally, “derivations” of the Schrödinger equation demonstrate its mathematical plausibility for describing wave-particle duality, but to date there are no universally accepted derivations of Schrödinger’s equation from appropriate axioms.

In the Copenhagen interpretation of quantum mechanics, the wave function is the most complete description that can be given of a physical system. Solutions to Schrödinger’s equation describe not only molecularatomic, and subatomic systems, but also macroscopic systems, possibly even the whole universe. The Schrödinger equation, in its most general form, is consistent with both classical mechanics and special relativity, but the original formulation by Schrödinger himself was non-relativistic.

The Schrödinger equation is not the only way to make predictions in quantum mechanics—other formulations can be used, such as Werner Heisenberg‘s matrix mechanics, and Richard Feynman‘s path integral formulation.




Dividing an Atom

The study of subatomic particles requires quantum mechanics.

The negatively charged electron has a mass equal to 11836 of that of a hydrogen atom. The remainder of the hydrogen atom’s mass comes from the positively charged proton.

A dark nebula or absorption nebula is a type of interstellar cloud that is so dense it obscures the light from objects behind it, such as background stars and emission or reflection nebulae.





Formation of disk galaxies

The key properties of disk galaxies, which are also commonly called spiral galaxies, are that they are very thin, rotate rapidly, and often show spiral structure. One of the main challenges to galaxy formation is the great number of thin disk galaxies in the local universe. The problem is that disks are very fragile, and mergers with other galaxies can quickly destroy thin disks.

Continue reading “Formation of disk galaxies”


Solar System Active Star

The Sun is a magnetically active star. It supports a strong, changing magnetic field that varies year-to-year and reverses direction about every eleven years around solar maximum.

The Sun’s magnetic field leads to many effects that are collectively called solar activity, including sunspots on the surface of the Sun, solar flares, and variations in solar wind that carry material through the Solar System.




The effects of solar activity on Earth include auroras at moderate to high latitudes and the disruption of radio communications and electric power. Solar activity is thought to have played a large role in the formation and evolution of the Solar System. Solar activity changes the structure of Earth’s outer atmosphere.

All matter in the Sun is in the form of gas and at high temperatures, plasma. This makes it possible for the Sun to rotate faster at its equator (about 25 days) than it does at higher latitudes (about 35 days near its poles). The differential rotation of the Sun’s latitudes causes its magnetic field lines to become twisted together over time, producing magnetic field loops to erupt from the Sun’s surface and trigger the formation of the Sun’s dramatic sunspots and solar prominences (see Magnetic reconnection).



This twisting action creates the solar dynamo and an 11-year solar cycle of magnetic activity as the Sun’s magnetic field reverses itself about every 11 years.



It Really Does Matter

Massive matter of mass


Matter should not be confused with mass, as the two are not quite the same in modern physics. For example, mass is a conserved quantity, which means that its value is unchanging through time, within closed systems.

However, matter is not conserved in such systems, although this is not obvious in ordinary conditions on Earth, where matter is approximately conserved.

Still, special relativity shows that matter may disappear by conversion into energy, even inside closed systems, and it can also be created from energy, within such systems.

However, because mass (like energy) can neither be created nor destroyed, the quantity of mass and the quantity of energy remain the same during a transformation of matter (which represents a certain amount of energy) into non-material (i.e., non-matter) energy. This is also true in the reverse transformation of energy into matter.

Venus and the transit of the sun

A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black disk moving across the face of the Sun.

The duration of such transits is usually measured in hours (the transit of 2012 lasted 6 hours and 40 minutes). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is more than 3 times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth.

Hubble is so important to our understanding (universe of cats)

Spiral Galaxy 

A spiral galaxy is a certain kind of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, forms part of the Hubble sequence. Spiral galaxies consist of a flat, rotating disc containing stars, gas and dust, and a central concentration of stars known as the bulge. These are surrounded by a much fainter halo of stars, many of which reside in globular clusters.

Edwin will never know Hubble



UK’s First Astronaut In Space

Tim Peake

Just one month after boarding the International Space Station, Peake has completed his first Spacewalk with fellow astronaut Tim Kopra. It’s fair to say the UK was firmly gripped by “Spacewalk fever” on January 15 2015.

Tim Peake takes a moment on the Spacewalk for a selfie.

UK astronaut Tim Peake described his first walk in space as “exhilarating”, as he posted photos – including a selfie – of the feat on Twitter.It will “be etched in my memory forever – quite an incredible feeling,” said Peake, the first astronaut representing the UK to carry out a spacewalk.He and US colleague Tim Kopra were outside the International Space Station (ISS) for four hours and 43 minutes.But their spacewalk was cut short after water leaked into Col Kopra’s helmet.The pair had already replaced a failed electrical box, which was their main objective.

UK newspaper The Guardian had this to say…

The moment was hardly lost on him. As Tim Peake clambered out of the International Space Station he nodded to the union flag emblazoned on his shoulder. To wear the patch was, he said, “a huge privilege, and a proud moment”.

Britain’s first European Space Agency astronaut began his maiden spacewalk shortly before 1pm on Friday as the orbiting station soared 250 miles above Australia. By the time he returned inside, he had circled the planet at least three times and witnessed six stunning sunsets or sunrises.

Emerging from the Quest airlock into the darkness of Earth’s shadow, Peake joined Nasa’s Tim Kopra for more than four hours of challenging work. Under the direction of ground staff in Houston, the astronauts overcame snagged tethers, a brief carbon dioxide scare, and a torn glove before the day was done.



Saturn and Cassini again I say

logo planet head
Saturn Cassini Passed through My Head

Flybys are a major element of Cassini’s tour. The spacecraft’s looping, elliptical path around Saturn is carefully designed to enable occasional visits to the many moons in the system. All flybys provide an opportunity to learn more about Saturn’s icy satellites, and encounters with giant Titan are actually used to navigate the spacecraft, changing its orbit or setting up future flybys.
Many of the most exciting encounters are “targeted” flybys, for which Cassini’s flight path is steered so the spacecraft will pass by a specific moon at a predetermined distance, referred to as “closest approach.” Cassini’s targeted flybys have yielded incredible close-up views and many groundbreaking science results. Visits to Dione and Hyperion, for example, as well as the daring Oct. 2008 dives through the Enceladus plume, have provided some of the great highlights of the mission.

It’s Cassini importance that counts




They survey and sniff, analyze and scrutinize. And of course, they take stunning images in various visible spectra. The 12 science instruments onboard the Cassini spacecraft are seemingly capable of doing it all. Each instrument is designed to carry out sophisticated scientific studies of Saturn, from collecting data in multiple regions of the electromagnetic spectrum, to studying dust particles, to characterizing Saturn’s plasma environment and magnetosphere.

The instruments gather data for 27 diverse science investigations, providing scientists with an enormous amount of information on the most beautiful planet in our Solar System.

Lepus is under Orion

When the sky is clear – you can even see Lepus on the horizon

I can make out Lepus tonight with my naked eye. The best view so far this autumn. Of course, Orion looks glorious as it always does on a clear night, though I find it much harder to see Lepus in such detail usually.

Lepus is a constellation lying just south of the celestial equator, immediately south of Orion. Its name is Latin for hare. Although the hare does not represent any particular figure in Greek mythology, Lepus was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is located below the constellation Orion (the hunter), and is sometimes represented as a hare being chased by Orion or, alternatively, by Orion’s hunting dogs.

Astronomy halloween with jupiter ghost


William Herschel discovered the nebula on February 7, 1785, and cataloged it as H IV.27. John Herschel observed it from the Cape of Good Hope, South Africa, in the 1830s, and numbered it as h 3248, and included it in the 1864 General Catalogue as GC 2102; this became NGC 3242 in J. L. E. Dreyer’s New General Catalogue of 1888.

This planetary nebula is most frequently called the Ghost of Jupiter, or Jupiter’s Ghost due to its similar size to the planet, but it is also sometimes referred to as the Eye Nebula.

The nebula measures around two light years long from end to end, and contains a central white dwarf with an apparent magnitude of eleven. The inner layers of the nebula
were formed some 1,500 years ago.

The two ends of the nebula are marked by FLIERs, lobes of fasting moving gas often tinted red in false-color pictures. NGC 3242 can easily be observed with amateur telescopes, and appears bluish-green to most observers. Larger telescopes can distinguish the outer halo as well.




definition of astronomer amateur

Amateur astronomy is a hobby whose participants enjoy watching the sky, and the abundance of objects found in it with the unaided eye, binoculars, or telescopes. Even though scientific research is not their main goal, many amateur astronomers make a contribution to astronomy by monitoring variable stars, tracking asteroids and discovering transient objects, such as comets and novae.

The typical amateur astronomer is one who does not depend on the field of astronomy as a primary source of income or support, and does not have a professional degree or advanced academic training in the subject. Many amateurs are beginners or hobbyists, while others have a high degree of experience in astronomy and often assist and work alongside professional astronomers.


Amateur astronomy is usually associated with viewing the night sky when most celestial objects and events are visible, but sometimes amateur astronomers also operate during the day for events such as sunspots and solar eclipses. Amateur astronomers often look at the sky using nothing more than their eyes, but common tools for amateur astronomy include portable telescopes and binoculars.

People have studied the sky throughout history in an amateur framework, without any formal method of funding. It is only within about the past century, however, that amateur astronomy has become an activity clearly distinguished from professional astronomy, and other related activities.



The Law according to Hubble

Universe Expansion 

Objects observed in deep space (extragalactic space, ~10 megaparsecs or more) are found to have a Doppler shift interpretable as relative velocity away from the Earth;
This Doppler-shift-measured velocity, of various galaxies receding from the Earth, is approximately proportional to their distance from the Earth for galaxies up to a few hundred megaparsecs away.

Hubble’s law is considered the first observational basis for the expansion of the universe and today serves as one of the pieces of evidence most often cited in support of the Big
Bang model. The motion of astronomical objects due solely to this expansion is known as the Hubble flow.

Although widely attributed to Edwin Hubble, the law was first derived from the general relativity equations by Georges Lemaître in a 1927 article where he proposed the expansion of the universe and suggested an estimated value of the rate of expansion, now called the Hubble constant.

Two years later Edwin Hubble confirmed the existence of that law and determined a more accurate value for the constant that now bears his name. Hubble inferred the recession velocity of the objects from their redshifts, many of which were earlier measured and related to velocity by Vesto Slipher in 1917.

The law is often expressed by the equation v = H0D, with H0 the constant of proportionality (Hubble constant) between the “proper distance” D to a galaxy (which can change over time, unlike the comoving distance) and its velocity v (i.e. the derivative of proper distance with respect to cosmological time coordinate; see Uses of the proper distance for some discussion of the subtleties of this definition of ‘velocity’). The SI unit of H0 is s−1 but it is most frequently quoted in (km/s)/Mpc, thus giving the speed in km/s of a galaxy 1 megaparsec (3.09×1019 km) away. The reciprocal of H0 is the Hubble time.



The emu of the milky way

The ancient night sky was studied and defined by the dark patches seen – not by the stars seen, in ancient aboriginal astronomy.

Dark patches in the sky


Unlike Greek celestial tradition, which focuses almost exclusively on stars, Aboriginal astronomy focuses on the Milky Way and often incorporates the dark patches between stars.

The Emu in the Sky, a story common to many Aboriginal groups, is an example of this — its body is made up of the dark patches in the Milky Way. The Boorong people saw the
same dark patches as the smoke from the fires of Nurrumbunguttias, the old spirits. The Kaurna people saw the Milky Way — called Wodliparri or hut river — as a large river
where a Yura (monster) lives in the dark patches.

The man behind the Maunder Minimum

Edward Walter Maunder

Serious Sunspots Study Started With Maunder…………

About the man…(12 April 1851 – 21 March 1928) was a British astronomer best remembered for his study of sunspots and the solar magnetic cycle that led to his identification of the period from 1645 to 1715 that is now known as the Maunder Minimum.

Edward Walter Maunder was born in 1851, in London, the youngest child of a minister of the Wesleyan Society. He attended King’s College London but never graduated. He took a job in a London bank to finance his studies. 


In 1873 Maunder returned to the Royal Observatory, taking a position as a spectroscopic assistant. Shortly after, in 1875, he married Edith Hannah Bustin, who gave birth to six children, 3 sons, 2 daughters and a son who died in infancy. Following the death of Edith in 1888, he met Annie Scott Dill Russell (1868–1947) in 1890, a mathematician and astronomer with whom he collaborated for the remainder of his life. In 1895 Maunder and Russell married. In 1916 Annie Maunder became one of the first women accepted by the Royal Astronomical Society.

Part of Maunder’s job at the Observatory involved photographing and measuring sunspots, and in doing so he observed that the solar latitudes at which sunspots occur varies in a regular way over the course of the 11 year cycle. After 1891, he was assisted in his work by his second wife, Annie Scott Dill Maunder (née Russell), a mathematician educated at Girton College in Cambridge. She worked as a “lady computer” at the Observatory from 1890 to 1895. In 1904, he published their results in the form of the “butterfly” diagram.

After studying the work of Gustav Spörer, who examined old records from the different observatories archives looking for changes of the heliographic latitude of sunspots, Maunder announced Spörer’s conclusions in own paper edited in 1894. The period, recognised earlier by Spörer, now bears Maunder’s name.

He travelled extensively for observations going to places such as the West Indies, Lapland, India, Algiers, Mauritius. His last eclipse expedition was to Labrador for the Solar eclipse of 30 August 1905 at the invitation of the Canadian government.




Mars its been a long journey

How Did We Get To Here…

Starting with the M.R.O.

Mars Reconnaissance Orbiter (MRO) is a multipurpose spacecraft designed to conduct reconnaissance and exploration of Mars from orbit. The US$720 million spacecraft was built by Lockheed Martin under the supervision of the Jet Propulsion Laboratory. The mission is managed by the California Institute of Technology, at the JPL, in La Cañada Flintridge, California, for the NASA Science Mission Directorate, Washington, D.C. It was launched August 12, 2005, and attained Martian orbit on March 10, 2006. In November 2006, after five months of aerobraking, it entered its final science orbit and began its primary science phase.

As MRO entered orbit, it joined five other active spacecraft which were either in orbit or on the planet’s surface:Mars Global Surveyor, Mars Express, 2001 Mars Odyssey, and the two Mars Exploration Rovers (Spirit and Opportunity); at the time, this set a record for the most operational spacecraft in the immediate vicinity of Mars. Mars Global Surveyor and the Spirit rover have since ceased to function; the remainder remain operational as of July 2015.

MRO contains a host of scientific instruments such as cameras, spectrometers, and radar, which are used to analyze the landforms, stratigraphy, minerals, and ice of Mars. It paves the way for future spacecraft by monitoring Mars’ daily weather and surface conditions, studying potential landing sites, and hosting a new telecommunications system. MRO’s telecommunications system will transfer more data back to Earth than all previous interplanetary missions combined, and MRO will serve as a highly capable relay satellite for future missions.

this galaxy is intermediate – lenticular

lenticular galaxy is a type of galaxy which is intermediate between an elliptical galaxy and a spiral galaxy in galaxy morphological classification schemes. Lenticular galaxies are disc galaxies (like spiral galaxies) which have used up or lost most of their interstellar matter and therefore have very little ongoing star formation.

They may, however, retain significant dust in their disks. As a result, they consist mainly of aging stars (like elliptical galaxies). Because of their ill-defined spiral arms, if they are inclined face-on it is often difficult to distinguish between them and elliptical galaxies.

Despite the morphological differences, lenticular and elliptical galaxies share common properties like spectral features, scaling relations and both can be considered early type galaxies which are passively evolving, at least in the local universe.
