POPSGalaxies found to be flowing together "He said another interesting idea proposed since the cosmic flow was detected is that instead of a gravitational pull by something beyond the observable universe, the galaxies are being pushed by an absence of mass in the local universe."

POPS How A Catholic Priest Gave Us The Primeval Atom Theory
Returning to Belgium in 1925, where he worked at the Catholic University of Leuven as a part-time lecturer, his big break came two years later in 1927 when he proposed his theory of an expanding Universe to explain the movement of the galaxies, published in the Annals of the Scientific Society of Brussels. Lemaitre was still pretty hazy about how the process of expansion could have begun. Like many scientists, he was still committed to the idea of a static Universe of unchanging size... Einstein, though interested, was largely dismissive, telling Lemaitre that, "Your calculations are good, but your physics is terrible". Einstein was also a little suspicious of the religious implications of these ideas. He declined to describe himself as an atheist (or a theist, or a pantheist) and liked to use the vocabulary of religion, most famously in his misguided rejection of much of quantum physics, "God does not play dice!" British physicist, Fred Hoyle coined the Big Bang term

POPSGiant Red Stars set a new Standard The most common red giants are the so-called red giant branch stars (RGB stars) whose shells are still fusing hydrogen into helium, while the core is inactive helium. Prominent bright red giants in the night sky include Aldebaran (Alpha Tauri), Arcturus (Alpha Bootis), and Gamma Crucis (Gacrux), while the even larger Antares (Alpha Scorpii) and Betelgeuse (Alpha Orionis) are red supergiants.

POPSMysterious New 'Dark Flow' Discovered in Space They discovered that the clusters were moving nearly 2 million mph (3.2 million kph) toward a region in the sky between the constellations of Centaurus and Vela. This motion is different from the outward expansion of the universe (which is accelerated by the force called dark energy).

POPSA Celestial Journey This is a "journey" throughout the cosmos, showing nebulae, galaxies, supernovas, stars and space clouds. The photos are provided by NASA . Acompaniying this video are the songs by Aeoliah : "Whispers Among The Stars" , "The Journey Home" and "Crystal Illumination" ; by Herb Ernst: "Celestial Ascent" and Deuter: "Waves Of Light" .

POPSCosmic crash unmasks dark matter It looks as if it is being seen through lots of little lenses. And each of these lenses represents a piece of dark matter. Astronomers used the Chandra X-ray telescope to map ordinary matter in the merging clusters, mostly in the form of hot gas, which glows brightly in X-rays. As the two clusters that formed MACSJ0025 merged at speeds of millions of kilometres per hour, hot gas in the two clusters collided and slowed down. However, the dark matter kept on going, passing right through the smash-up. The latest astronomical observations suggest that dark matter makes up some 23% of the Universe. Ordinary matter - such as the galaxies, gas, stars and planets - makes up just 4%. The remaining 73% is made up of another mysterious quantity; dark energy, which is responsible for speeding up the expansion of the cosmos.

POPSTelescope spots monster galactic cluster They theorize that the fact that it's 7.7 billion light years away (as far as they know) meant that it was before the acceleration due to dark energy made it impossible for galactic clusters that large to hold together. It reminded me of a poem by Hughes Mearns. 'Antigonish' As I was going up the stair, I saw a star that wasn’t there. It wasn’t there again today, I wish, that star would stay away. (I thought I'd adjust it to cover Light years, and dark matter.)

POPSThe World's Largest Particle Accelerator No one really knows what the machine will give birth to. But the equations suggest that some weird stuff could be just around the corner — maybe "dark matter," the invisible stuff that seems to hang around galaxies. "It's kind of an embarrassment that we don't know what 95 percent of the universe is made of by weight," Green says. "We hope — it's possible — we may be making dark matter." Some theories say it is possible the collider will cause miniature black holes to momentarily appear. But for now, what has appeared is a table of croissants, an urn of coffee, and more people. Everyone stands around in blue hard hats. They don't talk about black holes or dark matter. A few say things like "I hope the magnet doesn't fall."

POPSNGC 1512 NGC 1512 in the southern constellation of Horologium is located 30 million light-years away, relatively nearby as galaxies go, it is bright enough to be seen with amateur telescopes.
