Amateur Astronomer’s Always Have Something To Say About Orion
Betelgeuse is one of the largest stars currently known — with a radius around 1400 times larger than the Sun’s in the millimeter continuum. About 600 light-years away in the constellation of Orion (The Hunter), the red supergiant burns brightly, causing it to have only a short life expectancy.
The star is just about eight million years old, but is already on the verge of becoming a supernova.
When that happens, the resulting explosion will be visible from Earth, even in broad daylight.
It all seems very easy, this revolution game
But when you start to really play things won’t be quite the same.
Your intellectual theories on how it’s going to be
Don’t seem to take into account the true reality
Cos the truth of what you’re saying, as you sit there sipping beer
Is pain and death and suffering, but of course you wouldn’t care
You’re far too much of a man for that, if Mao did it so can you
What’s the freedom of us all against the suffering of the few?
That’s the kind of self-deception that killed ten million jews
Just the same false logic that all power-mongers use
So don’t think you can fool me with your political tricks
Political right, political left, you can keep your politics
Government is government and all government is force
Left or right, right or left, it takes the same old course
Oppression and restriction, regulation, rule and law
The seizure of that power is all your revolution’s for
You romanticise your heroes, quote from Marx and Mao
Well their ideas of freedom are just oppression now
Victoria is an impact crater on Mars located at 2.05°S, 5.50°W in the Meridiani Planum extraterrestrial plain, lying situated within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars.
This crater was first visited by the Mars Exploration Rover Opportunity. It is roughly 730 metres wide, nearly eight times the size of the crater Endurance, visited by Opportunity from sols 951 to 1630.
It is informally named after Victoria – one of the five ships of Ferdinand Magellan and the first ship to circumnavigate the globe – and formally named after Victoria, Seychelles. Along the edges of the crater are many outcrops within recessed alcoves and promontories, named for bays and capes that Magellan discovered.
Globular clusters are among the oldest objects in the Milky Way Galaxy, which thus set a lower limit on the age of the galaxy. Age estimates of the oldest of these clusters gives a best fit estimate of 12.6 billion years, and a 95% confidence upper limit of 16 billion years.
Galaxy does not suffer from crows feet in its selfie images ever.
The Milky Way began as one or several small overdensities in the mass distribution in the Universe shortly after the Big Bang. Some of these overdensities were the seeds of globular clusters in which the oldest remaining stars in what is now the Milky Way formed. These stars and clusters now comprise the stellar halo of the Galaxy.

The Iris Nebula, also NGC 7023 and Caldwell 4, is a bright reflection nebula and Caldwell object in the constellation Cepheus. NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +7 star, SAO 19158.
It shines at magnitude +6.8. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across.
Matter commonly exists in four states (or phases): solid, liquid and gas, and plasma. However, advances in experimental techniques have revealed other previously theoretical phases, such as Bose–Einstein condensates and fermionic condensates. A focus on an elementary-particle view of matter also leads to new phases of matter, such as the quark–gluon plasma.
For much of the history of the natural sciences people have contemplated the exact nature of matter. The idea that matter was built of discrete building blocks, the so-called particulate theory of matter, was first put forward by the Greek philosophers Leucippus (~490 BC) and Democritus (~470–380 BC).
Albert Einstein showed that ultimately all matter is capable of being converted to energy (known as mass-energy equivalence) by the famous formula E = mc2, where E is the energy of a piece of matter of mass m, times c2 the speed of light squared.
As the speed of light is 299,792,458 metres per second (186,282 mi/s), a relatively small amount of matter may be converted to a large amount of energy. An example is that positrons and electrons (matter) may transform into photons (non-matter). However, although matter may be created or destroyed in such processes, neither the quantity of mass or energy change during the process.
The giraffe weevil is a weevil endemic to Madagascar. It derives its name from an extended neck much like that of the common giraffe. The giraffe weevil is sexually dimorphic, with the neck of the male typically being 2 to 3 times the length of that of the female.
Madagascar – Species – Adaptation
Most of the body is black with distinctive red elytra covering the flying wings. The total body length of the males is just under an inch (2.5 cm), among the longest for any attelabid species. The extended neck is an adaptation that assists in nest building and fighting.
When it comes time to breed, the mother-to-be will roll and secure a leaf of the host plant, Dichaetanthera cordifolia and Dichaetanthera arborea (a small tree in the family Melastomataceae), and then lay a single egg within the tube. She will then snip the roll from the remaining leaf in preparation of the egg hatching.
Orbital ATK’s robotic Cygnus cargo spacecraft is scheduled to launch toward the International Space Station (ISS) Tuesday atop a United Launch Alliance Atlas V rocket at 11:11 a.m. EDT (1511 GMT) from Florida’s Cape Canaveral Air Force Station. You can watch it live here at Space.com, courtesy of NASA TV, or directly at the space agency’s YouTube channel.
Cygnus has flown a number of such resupply runs in the past, but this liftoff will be special, from a viewer’s perspective at least: You’ll be able to get a pad’s-eye view, in 360 degrees.
“To view in 360, use a mouse or move a personal device to look up and down, back and forth, for a 360-degree view around Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida,” NASA officials wrote in a statement. “Those who own virtual reality headsets will be able to look around and experience the view as if they were actually standing on the launch pad.”
The Cygnus is packed with more than 7,600 lbs. (3,450 kilograms) of scientific gear, hardware and supplies for the ISS crew — so much cargo that the mission will employ an Atlas V rather than Orbital’s own Antares booster, which is not quite as powerful. (An Antares is slated to loft the next Cygnus mission, which will lift off this summer.)
The marine iguana is an iguana found only on the Galápagos Islands that has the ability, unique among modern lizards, to forage in the sea, making it a marine reptile. The iguana can dive over 9 m (30 ft) into the water.
It has spread to all the islands in the archipelago, and is sometimes called the Galápagos marine iguana. It mainly lives on the rocky Galápagos shore to warm from the comparatively cold water, but can also be spotted in marshes and mangrove beaches.
Marine iguanas are medium-sized lizards (200–340 mm (7.9–13.4 in), adult snout–vent length) and are unique as they are marine reptiles due to their foraging on inter-
and subtidal algae only. These iguanas forage exclusively in the cold sea, which leads them to behavioral adaptations for thermoregulation.
On his visit to the islands, despite making extensive observations on the creatures, Charles Darwin was revolted by the animals’ appearance, writing:
The black Lava rocks on the beach are frequented by large (2–3 ft [0.6–0.9 m]), disgusting clumsy Lizards. They are as black as the porous rocks over which they crawl
& seek their prey from the Sea. I call them ‘imps of darkness’. They assuredly well-become the land they inhabit.
Researchers theorize that land iguanas and marine iguanas evolved from a common ancestor since arriving on the islands from South America, presumably by rafting.
The marine iguana diverged from the land iguana some 8 million years ago, which is older than any of the extant Galapagos islands. It is therefore thought that the ancestral species inhabited parts of the volcanic archipelago that are now submerged.
The two species remain mutually fertile in spite of being assigned to distinct
genera, and they occasionally hybridize where their ranges overlap.
Although the marine iguana resembles a lizard, it has developed several adaptations that set it apart. These include blunt noses for efficiently grazing seaweed, powerful limbs and claws for climbing and holding onto rocks, and laterally flattened tails for improved swimming.
Compared to the land iguana its limb bones, especially those from the front limbs, have become more heavy and compact (osteosclerosis), providing ballast to help with diving.
The marine iguana has no evolved defences against introduced predators. These include rats, which tend to feed on the eggs, cats, which can feed on juveniles, and dogs
which may threaten adults.
Amblyrhynchus cristatus is not always black; the young have a lighter coloured dorsal stripe, and some adult specimens are grey, and adult males vary in colour with
the season. Dark tones allow the lizards to rapidly absorb heat to minimize the period of lethargy after emerging from the water. The marine iguana lacks agility on
land but is a graceful swimmer. Its laterally flattened tail and spiky dorsal fin aid in propulsion, while its long, sharp claws allow it to hold onto rocks in strong
Norma is a small constellation in the Southern Celestial Hemisphere between Scorpius and Centaurus, one of twelve drawn up in the 18th century by French astronomer Nicolas Louis de Lacaille and one of several depicting scientific instruments.
Its name is Latin for normal, referring to a right angle, and is variously considered to represent a rule, a carpenter’s square, a set square or a level. It remains one of the 88 modern constellations.
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.
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.
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 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.
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.
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.
Find out more about our brilliant UK insect hunters.
Getting to know our night creatures and how we can help and support the ‘caped crusaders’ of the night sky – the brilliant bats. The best place for information on bats in the UK is The Bat Conservation Trust, it has absolutely everything you need to know and you don’t have to be a member in order to see the content.
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.
Constellations are hard to find with only a short time of dark sky. The Milky Way is a great view at this time, if you know where to look. I like to see it where I live because the view is usually quite bad with light pollution.
Following the discovery of the planet Neptunein 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.
Apatheismalso known aspragmatic atheismorpractical atheism, is acting with apathy or disregard toward belief or disbelief in adeityor 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 naturalphenomenawithout reference to any deities. The existence of gods is not rejected, but may be designated unnecessary or useless; gods neither provide purpose tolife, nor influenceeveryday 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.
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.
“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.”
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
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.
