April Flowers for redOrbit.com - Your Universe Online Astronomers are hoping to gain a new understanding of how galaxies grow from watching a distant “twin” of the Milky Way as it is swallowing another galaxy. Dr. Caroline Foster of the Australian Astronomical Observatory (AAO) led the team that has been studying NCG 4651, called the Umbrella galaxy for the “parasol” of stars that are all that remain of the galaxy being consumed. Umbrella can be found approximately 62 million...

Astronomers have discovered a relic from the early universe - a star that may have been among the second generation of stars to form after the Big Bang. Located in the dwarf galaxy Sculptor some 290,000 light-years away, the star has a remarkably similar chemical make-up to the Milky Way's oldest stars. Its presence supports the theory that our galaxy underwent a "cannibal" phase, growing to its current size by swallowing dwarf galaxies and other galactic building blocks. "This star likely is...

After years of successful concealment, the most primitive stars outside our Milky Way galaxy have finally been unmasked. New observations using ESO's Very Large Telescope have been used to solve an important astrophysical puzzle concerning the oldest stars in our galactic neighborhood "” which is crucial for our understanding of the earliest stars in the Universe. "We have, in effect, found a flaw in the forensic methods used until now," says Else Starkenburg, lead author of the paper...

The high speed of stars and apparent presence of "Ëœdark matter' in the satellite galaxies that orbit our Milky Way Galaxy presents a direct challenge to Newton's theory of gravitation, according to physicists from Germany, Austria and Australia. Professor Pavel Kroupa of the University of Bonn's Argelander-Institut fuer Astronomie (AlfA) will discuss the results of the team's two studies in a presentation on Wednesday 22nd April at the European Week of Astronomy and Space Science...

VLT shows that our Milky Way galaxy is cut from a different cloth A large survey, made with ESO's VLT, has shed light on our Galaxy's ancestry. After determining the chemical composition of over 2000 stars in four of the nearest dwarf galaxies to our own, astronomers have demonstrated fundamental differences in their make-up, casting doubt on the theory that these diminutive galaxies could ever have formed the building blocks of our Milky Way Galaxy. "The chemistry we see in the stars in...

WASHINGTON (Reuters) - Two dim dwarf galaxies are the Milky Way's newest-known galactic companions, astronomers studying a vast swath of the sky reported on Monday. This brings the total number of dwarf galaxies in the Milky Way's cosmic neighborhood to 14. But theorists believe there could conceivably be hundreds more. The two newly detected dwarfs were found in the direction of the constellations Canes Venatici (the hunting dogs) and Bootes (the herdsman), scientists studying the...
