Galaxies throughout the universe are ablaze with star birth. But for a nearby, small spiral galaxy, the star-making party is almost over. Astronomers were surprised to find that star-formation activities in the outer regions of NGC 2976 have been virtually asleep because they shut down millions of years ago. The celebration is confined to a few die-hard partygoers huddled in the galaxy's inner region.
The cold dark matter theory has been used for more than 20 years to explain how the smooth universe from the big bang evolved into the galaxy-rich cosmos we see today. But there was a problem: the theory suggested most galaxies should have far more stars and dark matter at their cores than they actually do. New research solves the problem.
Is there anybody out there? In Alejandro Jenkins’ case, the question refers not to whether life exists elsewhere in the universe, but whether it exists in other universes outside of our own.

A new study of images from NASA's Chandra X-ray Observatory on supernova remnants - the debris from exploded stars - shows that the symmetry of the remnants, or lack thereof, reveals how the star exploded. This is an important discovery because it shows that the remnants retain information about how the star exploded even though hundreds or thousands of years have passed.
In a paper published in Nature, Hilke Schlichting of the California Institute of Technology is reporting that the telltale signature of a Kuiper Belt Object measuring only one-half mile across was extracted from Hubble's Fine Guidance Sensors engineering data, not direct observations.
This Hubble picture postcard of hundreds of brilliant blue stars wreathed by warm, glowing clouds is the most detailed view of the largest stellar nursery in our local galactic neighborhood. The massive, young stellar grouping, called R136, is only a few million years old and resides 170,000 light-years away in the 30 Doradus Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way. The Hubble Wide Field Camera 3 observations were taken Oct. 20-27, 2009.
The threat from orbital debris is a growing international concern. Experts from around the world are meeting this week to identify steps that can be taken to help reduce this menacing problem.
It's summer at the South Pole now, with 24 hours of daylight. And that marks the high season for research, despite extreme temperatures hovering around 40 degrees below zero with the wind chill! James Roth and Chris Elliott, both senior electronics instrument specialists from the University of Delaware, and their international colleagues are working at South Pole Station now, helping to construct the world's largest neutrino telescope, named “IceCube,” over a mile deep in the Antarctic ice sheet. Our UD research team is constructing the telescope's surface array of detectors called “IceTop.”
NASA's Hubble Telescope has made the deepest image of the universe ever taken in near-infrared light. The faintest and reddest objects in the image are galaxies that formed 600 million years after the Big Bang. No galaxies have been seen before at such early times. The image was taken in late August 2009 with Hubble's new Wide Field Camera 3.

Dr. Rodger Doxsey, head of the Space Telescope Science Institute's (STScI) Hubble Mission Office, passed away on October 13 after a prolonged illness. The New York native was 62 years old. Doxsey oversaw Hubble science operations at STScI in Baltimore, Md., for nearly three decades. Astronomers credit Doxsey for being one of the key Hubble program people who had a working knowledge of the extremely complex Hubble Space Telescope from top to bottom. Doxsey dedicated his career to making Hubble a success, working closely with the scientists and engineers at the institute that operate the telescope, the engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., and the scientists from around the world who use the telescope.
