Personality trait a factor in weight loss: StudySeptember 25th, 2009 LONDON - Can personality trait be a factor in weight loss? A new study says yes. Stating an example, the study says being too optimistic could derail weight loss efforts.
Andromeda galaxy expanded by cannibalizing on stars from other galaxiesSeptember 3rd, 2009 LONDON - A new research has shown that the vast Andromeda galaxy appears to have expanded by cannibalizing on stars from other galaxies. According to a report by BBC News, when an international team of scientists mapped Andromeda, they discovered stars that they said were "remnants of dwarf galaxies".
Astronomers detect hyperactive galaxies by looking back 11 bln yrs into the pastAugust 6th, 2009 WASHINGTON - Looking almost 11 billion years into the past, astronomers have measured the motions of stars for the first time in a very distant galaxy and clocked speeds upwards of one million miles per hour, about twice the speed of our Sun through the Milky Way. The fast-moving stars shed new light on how these distant galaxies, which are a fraction the size of our Milky Way, may have evolved into the full-grown galaxies seen around us today.
Astronomers discover rare 'Green Pea' galaxiesJuly 28th, 2009 WASHINGTON - A team of astronomers has discovered a group of rare galaxies called the "Green Peas", which could lend unique insights into how galaxies form stars in the early universe. The galaxies were discovered with the help of citizen scientists working through an online project called Galaxy Zoo.
Astronomers see high-speed galaxy collision in actionJuly 10th, 2009 WASHINGTON - Astronomers at the Chandra X-ray Observatory have spotted a galaxy collision in action, with one galaxy passing through the core of other galaxies at almost 2 million miles per hour. The image obtained is of Stephan's Quintet, a compact group of galaxies discovered about 130 years ago and located about 280 million light years from Earth.
Scientist uses new instrument to dissect nearby galaxies to learn how stars formJuly 10th, 2009 WASHINGTON - A scientist is using a new instrument at the University of Texas at Austin's McDonald Observatory to dissect nearby galaxies to learn how stars form, and in the process, generating a flood of new information that will benefit other scientists' work. The scientist in question is University of Texas at Austin graduate student Guillermo A.
Even minor weight loss 'ups fertility' in obese womenJuly 1st, 2009 LONDON - A new study has suggested that minor weight loss in obese women could boost their chances of getting pregnant. Professor Bill Ledger, from the University of Sheffield, and colleagues said conducted a three-month study of 40 obese women who were not ovulating.
"Cosmic blobs" a result of growing supermassive black holesJune 25th, 2009 WASHINGTON - New data obtained from NASA's Chandra X-ray Observatory and other telescopes has pinpointed the source of "cosmic blobs" as growing supermassive black holes. This discovery helps resolve the true nature of gigantic blobs of gas observed around very young galaxies.
Weird space blobs turn out to be adolescent galaxies throwing final tantrum before growing upJune 24th, 2009 Telescope finds space blobs are pubescent galaxiesWASHINGTON — Mysterious space blobs aren't infant galaxies as astronomers once thought. Scientists say they mostly consist of galaxies going through puberty, all hot and bothered.
'Cosmic cannonballs' spotted by astronomers in early UniverseJune 10th, 2009 LONDON - Astronomers have detected evidence of a new clutch of tiny, dense galaxies, dubbed 'cosmic cannonballs', which thrived in the early Universe, and are nowhere to be seen today. According to a report in New Scientist, the ultra-dense galaxies, which were already full of old stars when the universe was less than 3 billion years old, were first reported in 2008.
Kirstie Alley wants to lose 80 pounds to wear bikini againMay 1st, 2009 WASHINGTON - American actress Kirstie Alley has revealed that her one desire right now is to lose 80 pounds so that she can wear a bikini again. Alley, 58, said in an interview on the "Oprah Winfrey Show" on April 30 that she is ready to work out, and is sorry for the people she had let down.
Starbursts in dwarf galaxies last 100 times longer than astronomers thoughtMay 1st, 2009 WASHINGTON - An analysis of archival images of small, or dwarf, galaxies taken by NASA's Hubble Space Telescope suggests that starbursts, intense regions of star formation, sweep across the whole galaxy and last 100 times longer than astronomers thought. The longer duration may affect how dwarf galaxies change over time, and therefore may shed light on galaxy evolution.
Giant galaxies born 6-7 billion years earlier than expectedApril 24th, 2009 WASHINGTON - Astronomers have discovered large galaxies that have not changed much in size for the last 9 billion years, which suggests these cosmic giants were born 6-7 billion years earlier than expected. The most popular model for galaxy formation is a bottom-up or hierarchical model in which small galaxies gradually develop into larger ones over a long period of time.
Discovery of recently formed galaxies poses challenge to galaxy formation theoriesApril 11th, 2009 WASHINGTON - A team of astronomers has found a sample of massive galaxies with properties that suggest they may have formed relatively recently, a discovery that poses challenge to galaxy formation theories. This runs counter to the widely-held belief that massive, luminous galaxies (like our own Milky Way Galaxy) began their formation and evolution shortly after the Big Bang, some 13 billion years ago.
Hubble provides new evidence for dark matter around small galaxiesMarch 13th, 2009 WASHINGTON - The NASA/ESA Hubble Space Telescope has uncovered a strong new line of evidence that halos of dark matter are embedded around small galaxies. Looking into the turbulent center of the nearby Perseus galaxy cluster, Hubble discovered a large population of small galaxies that have remained intact while larger galaxies around them are being ripped apart by the gravitational tug of other galaxies.
