Our Local Bubble

Close Stars To The Solar System

The Orion–Eridanus Superbubble, or Eridanus Soft X-ray Enhancement is a superbubble located west of the Orion Nebula. The region is formed from overlapping supernova remnants that may be associated with the Orion OB1 stellar association; the bubble is approximately 1200 ly across. It is the nearest superbubble to the Local Bubble containing the Sun, with the respective shock fronts being about 500 ly apart.

Bubble Orion Eridanus

The Local Bubble is a cavity in the interstellar medium (ISM) in the Orion Arm of the Milky Way. It contains, among others, the Local Interstellar Cloud and the G-cloud. (The Local Interstellar Cloud contains our Solar System.) It is at least 300 light years across and has a neutral-hydrogen density of about 0.05 atoms/cm3, or approximately one tenth of the average for the ISM in the Milky Way (0.5 atoms/cm3), and one sixth that of the Local Interstellar Cloud (0.3 atoms/cm3). The hot diffuse gas in the Local Bubble emits X-rays.

The very sparse, hot gas of the Local Bubble is the result of supernovae that exploded within the past ten to twenty million years. It was once thought that the most likely candidate for the remains of this supernova was Geminga (“Gemini gamma-ray source”), a pulsar in the constellation Gemini. More recently, however, it has been suggested that multiple supernovae in subgroup B1 of the Pleiades moving group were more likely responsible becoming a remnant supershell.

 

Near To Orion Is Enough

So I Will Feature the Eridanus Constellation

Eridanus is a constellation in the southern hemisphere. It is represented as a river. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is the sixth largest of the modern constellations. The same name was later taken as a Latin name for the real Po River and also for the name of a minor river in Athens.

Eridanus contains the galaxies NGC 1232, NGC 1234, NGC 1291 and NGC 1300, a grand design barred spiral galaxy.

The Night Sky Unicorn

Monoceros is nothing that interesting to look at with the naked eye as it contains no really bright stars. Those stars are: Alpha Monocerotis which has a visual magnitude of 3.93, slightly brighter than Gamma Monocerotis at 3.98.

This is one for the telescope owning astronomer as it does have interesting objects to see.

Deep-sky objects

Monoceros contains many clusters and nebulae, most notable among them:

  • M50, an open cluster
  • The Rosette Nebula (NGC 2237, 2238, 2239, and 2246) is a diffuse nebula in Monoceros. It has an overall magnitude of 6.0 and is 4900 light-years from Earth. The Rosette Nebula, over 100 light-years in diameter, has an associated star cluster and possesses many Bok globules in its dark areas. It was independently discovered in the 1880s by Lewis Swift (early 1880s) and Edward Emerson Barnard (1883) as they hunted for comets.
  • The Christmas Tree Cluster (NGC 2264) is another open cluster in Monoceros. Named for its resemblance to a Christmas tree, it is fairly bright at an overall magnitude of 3.9; it is 2400 light-years from Earth. The variable star S Monocerotis represents the tree’s trunk, while the variable star V429 Monocerotis represents its top.
  • The Cone Nebula (NGC 2264), associated with the Christmas Tree Cluster, is a very dim nebula that contains a dark conic structure. It appears clearly in photographs, but is very elusive in a telescope. The nebula contains several Herbig-Haro objects, which are small irregularly variable nebulae. They are associated with protostars.
  • NGC 2254 is an open cluster with an overall magnitude of 9.7, 7100 light-years from Earth. It is a Shapley class f and Trumpler class I 2 p cluster, meaning that it appears to be a fairly rich cluster overall, though it has fewer than 50 stars. It appears distinct from the background star field and is very concentrated at its center; its stars range moderately in brightness.
  • Hubble’s Variable Nebula (NGC 2261) is a nebula with an approximate magnitude of 10, 2500 light-years from Earth. Though it is named for Edwin Hubble, it was discovered in 1783 by William Herschel. Hubble’s Variable Nebula is illuminated by R Monocerotis, a young variable star embedded in the nebula; the star’s unique interaction with the material in the nebula makes it both an emission nebula and a reflection nebula. One hypothesis regarding their interaction is that the nebula and its illuminating star are a very early stage planetary system.

Getting to know the Satellites 

The Solar System’s planets and officially recognised dwarf planets are known to be orbited by 182 natural satellites, or moons. 19 moons in the Solar System are large enough to be gravitationally rounded, and thus would be considered planets or dwarf planets if they were in direct orbit around the Sun.

Moons are classed in two separate categories according to their orbits: regular moons, which have prograde orbits (they orbit in the direction of their planets’ rotation) and lie close to the plane of their equators, and irregular moons, whose orbits can be pro- or retrograde(against the direction of their planets’ rotation) and often lie at extreme angles to their planets’ equators. Irregular moons are probably minor planets that have been captured from surrounding space. Most irregular moons are less than 10 kilometres (6.2 mi) in diameter.

Bad light for galaxy view

It just isn’t dark enough. On the best of a bad lot, and in August – the sky right now is almost cloud free. Light pollution is the biggest culprit. I can see the Pegasus constellation which means I should be able to make out the Andromeda galaxy with just my naked eye.

If I had binoculars or a telescope I would find it quite easily but that’s not the point. It’s fantastic to be able to see another galaxy by looking up at the night sky if you are in a ‘good’ dark place.

Bat Fact

Bats are not blind; in fact they can see almost as well as humans. But to fly around and hunt for insects in the dark, they use a remarkable high frequency system called echolocation.

Echolocation works in a similar way to sonar. Bats make calls as they fly and listen to the returning echoes to build up a sonic map of their surroundings. The bat can tell how far away something is by how long it takes the sounds to return to them.

After helping a hedgehog last week, my partner then found out it had died due to poisoning. Slug pellets being the culprit.

In a well maintained garden you should not need slug pellets. Personally, I think they should be banned. That hedgehog suffered an agonising death that was all so unnecessary.

We would like to thank The Cuan Rescue Center for all their work in helping and rescuing our UK Wildlife.

Another World Another Planet

Finding That Elusive One

Following the discovery of the planet Neptune in 1846, there was considerable speculation that another planet might exist beyond its orbit.

The search began in the mid-19th century and culminated at the start of the 20th with Percival Lowell’s quest for Planet X. Lowell proposed the Planet X hypothesis to explain apparent discrepancies in the orbits of the giant planets, particularly Uranus and Neptune, speculating that the gravity of a large unseen ninth planet could have perturbed Uranus enough to account for the irregularities.

Clyde Tombaugh’s discovery of Pluto in 1930 appeared to validate Lowell’s hypothesis, and Pluto was officially named the ninth planet. In 1978, Pluto was conclusively determined to be too small for its gravity to affect the giant planets, resulting in a brief search for a tenth planet.

The search was largely abandoned in the early 1990s, when a study of measurements made by the Voyager 2 spacecraft found that the irregularities observed in Uranus’s orbit were due to a slight overestimation of Neptune’s mass.

After 1992, the discovery of numerous small icy objects with similar or even wider orbits than Pluto led to a debate over whether Pluto should remain a planet, or whether it and its neighbours should, like the
asteroids, be given their own separate classification.

Although a number of the larger members of this group were initially described as planets, in 2006 the International Astronomical Union reclassified Pluto and its largest neighbours as dwarf planets, leaving Neptune the farthest known planet in the Solar System.

Apatheism – Is it a practical and misleading deity doubt monster?

Gif gallery galaxy
Dark Sky Eye

 

Apatheism also known as pragmatic atheism or practical atheism, is acting with apathy or disregard toward belief or disbelief in a deity or deities (a god or gods) due to the lack of reason, motivation, or will to express interest in theism.

An apatheist is someone who is not interested in accepting or denying any claims that gods exist or do not exist. An apatheist lives as if there are no gods and explains natural phenomena without reference to any deities. The existence of gods is not rejected, but may be designated unnecessary or useless; gods neither provide purpose to life, nor influence everyday life, according to this view.

In other words, apatheists consider the question of the existence of gods as neither meaningful nor relevant to their lives. Some apatheists hold that if it were possible to prove that God does or does not exist, their behavior would not change.

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.

 

Corpus_clock_haywired
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.

Source

 

 

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

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.

atoms-and-molecules-techhydraWebsite

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.

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.

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.

 

lemonslice_nebula_coleyartastro_in_spacesuit

 

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.

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.

Source – BBC News

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.
