Hubble Goes to the eXtreme to Assemble Farthest-Ever View of the Universe Hubble Goes to the eXtreme to Assemble Farthest-Ever View of the Universe Like photographers assembling a portfolio of best shots, astronomers have assembled a new, improved portrait of mankind's deepest-ever view of the universe. (Credit: NASA; ESA; G. Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The Hubble Ultra Deep Field is an image of a small area of space in the constellation Fornax, created using Hubble Space Telescope data from 2003 and 2004. The new full-color XDF image is even more sensitive, and contains about 5,500 galaxies even within its smaller field of view. Magnificent spiral galaxies similar in shape to our Milky Way and the neighboring Andromeda galaxy appear in this image, as do the large, fuzzy red galaxies where the formation of new stars has ceased.

Ghostly gamma-ray beams blast from Milky Way's center (Phys.org) -- As galaxies go, our Milky Way is pretty quiet. Active galaxies have cores that glow brightly, powered by supermassive black holes swallowing material, and often spit twin jets in opposite directions. In contrast, the Milky Way's center shows little activity. But it wasn't always so peaceful. New evidence of ghostly gamma-ray beams suggests that the Milky Way's central black hole was much more active in the past. "These faint jets are a ghost or after-image of what existed a million years ago," said Meng Su, an astronomer at the Harvard-Smithsonian Center for Astrophysics (CfA), and lead author of a new paper in the Astrophysical Journal. "They strengthen the case for an active galactic nucleus in the Milky Way's relatively recent past," he added. The two beams, or jets, were revealed by NASA's Fermi space telescope. The newfound jets may be related to mysterious gamma-ray bubbles that Fermi detected in 2010. The two structures also formed differently.
Mysterious New Object Discovered in Space A strange and mysterious new object in space may the brightest and long-lasting "micro-quasar" seen thus far, a miniature version of the brightest objects in the universe. The object suddenly began pumping out radio waves last year in the relatively nearby galaxy M82, some 10 million light-years away. Its discovery was announced Tuesday. "The new object, which appeared in May 2009, has left us scratching our heads — we've never seen anything quite like this before," said researcher Tom Muxlow, a radio astronomer at the University of Manchester's Jodrell Bank Observatory in England. M82 is a "starburst galaxy," one that churns out new stars at a prodigious rate. In comparison, the mystery object turned on very rapidly within a few days and has shown no sign of dying down, even after nearly a year. Quasars big and small Quasars are found in the center of galaxies and contain supermassive black holes. However, this newfound object seems to lie roughly 100 light years from M82's heart ?
Quantum leap: Magnetic properties of a single proton directly observed for the first time Most important milestone in the direct measurement of the magnetic moment of the proton and its anti-particle has been achieved / Focusing the matter-antimatter symmetry Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM), together with their colleagues from the Max Planck Institute for Nuclear Physics in Heidelberg and the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, have observed spin quantum-jumps with a single trapped proton for the first time. The fact that they have managed to procure this elusive data means that they have overtaken their research competitors at the elite Harvard University and are now the global leaders in this field. The result is a pioneering step forward in the endeavor to directly measure the magnetic properties of the proton with high precision. The proton has an intrinsic angular momentum or spin, just like other particles. The research work carried out by the team of Professor Dr.
Interactive 3D model of Solar System Planets and Night Sky Glowing Nebula's Clouds Look Like Giant Human Face in New Photo | NGC 3324, Nebulas & Star Formation | Space Photos & European Southern Observatory The wispy clouds of a distant nebula bursting with newborn stars take on an eerie face-like shape sculpted by stellar winds in a new photo snapped by a telescope in Chile. The hotbed of star birth, called NGC 3324, is full of hot young stars, whose ultraviolet radiation is making the gas clouds glow. The stellar wind and radiation from the newborn stars has also punched out a cavity in the surrounding gas and dust. The edge of the wall of gas and dust at the right in the photo resembles the profile of a human face, with a ridge in the center that looks like a nose. Astronomers often attach nicknames to nebulas based on their shape and their earthly likenesses. The new image was captured by the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the European Southern Observatory's (ESO) La Silla Observatory in Chile's Atacama Desert. Strong stellar winds and intense ultraviolet radiation from these young stars have carved out a pocket in the nearby gas and dust.
