POPS Astronomers See 'Skeleton' of the Universe
Viewed through the world's most powerful telescopes, the discovery "is the first observation of such a prominent galaxy structure in the distant universe, providing further insight into the cosmic web and how it formed," according to a statement by the European Southern Observatory (ESO). The assembly of galaxies form filaments "millions of light years long and constitute the skeleton of the universe," it says. "Galaxies gather around them, and immense galaxy clusters form at their intersections, lurking like giant spiders waiting for more matter to digest," it adds. The filaments are located about 6.7 billion light-years away and extend over at least 60 million light-years, the scientists say, adding the structure very likely stretches beyond the area they probed, warranting further observations. "This is the first time that we have observed such a rich and prominent structure in the distant universe," says ESO's Masayuki Tanaka, who led the study.

POPSInvisible hand in invisible matter. Dark matter might not exist. Dr Famaey added, "If we account for our observations with a modified law of gravity, it makes perfect sense to replace the effective action of hypothetical dark matter with a force closely related to the distribution of visible matter." The implications of the new research could change some of the most widely held scientific theories about the history and expansion of the universe. Lead researcher Dr. Gianfranco Gentile at the University of Ghent concludes, "Understanding this puzzling conspiracy is probably the key to unlock the formation of galaxies and their structures." What about NASA's direct proof on dark matter's existance? Broken study? This is actually makes sense, but so far is a little hard to accept. Does anyone have any ideas about this?

POPSHerschel scans hidden Milky Way Herschel intends to study large regions of the Milky Way in its combined Spire-Pacs scanning mode. The instruments will, of course, also work independently. The mission is due to go into routine operations in the next few weeks. However, its third instrument is currently down after experiencing a fault. Engineers can switch to a back-up system to reactivate the Heterodyne Instrument for the Far Infrared (HiFi), but they do not intend to do that until they have satisfied themselves the cause the anomaly is properly understood. The Dutch-led HiFi is a spectrometer that will identify elements and molecules in the clouds of gas and dust which give rise to stars.

POPSPhysicist unlocking the mysteries of neighboring galaxies "...Our observations also suggest that the Triangulum Galaxy is being ripped apart by Andromeda." Andromeda, and our own galaxy the Milky Way, are the two largest members of a small cluster of galaxies known as the Local Group. Triangulum, the third largest member of the Local Group, is about one-tenth the size of Andromeda. "Within a few billion years Triangulum will be completely destroyed by Andromeda and its stars will be dispersed throughout the Andromeda halo," says Dr. Widrow. "And a few billion years after that, Andromeda and the Milky Way will collide and merge together to form a giant elliptical galaxy."
