Most Distant Galaxy Record Broken
2012-11-15 22:10:07

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have found the most distant galaxy ever seen in the universe by using NASA's Hubble and Spitzer space telescopes. The newly discovered galaxy, named MACS0647-JD, is only a tiny fraction of the size of our Milky Way galaxy, and is observed at 420 million years after the big bang. MACS0647-JD offers a glimpse into what the universe was like when it was just three percent of its present age of 13.7 billion years old....

[ Watch the Video: Gigapixel View Of Milky Way ] Lee Rannals for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) announced this morning that a team of astronomers have catalogued over 84 million stars in the central parts of the Milky Way. This dataset contains more than ten times more stars than previous studies, and is a major step forward for understanding our galaxy. “By observing in detail the myriads of stars surrounding the center of the...

[WATCH VIDEO: Computer Model Shows a Disk Galaxy´s Life History] Lee Rannals for redOrbit.com — Your Universe Online After a comprehensive study of hundreds of galaxies, astronomers have uncovered a surprising trend in galaxy evolution. The team studied a sample of 544 blue galaxies from the Deep Extragalactic Evolutionary Probe 2 (DEEP2) Redshift Survey, and wrote about their findings in The Astrophysical Journal. "Astronomers thought disk galaxies in the nearby...

Milky Way Larger Than Previously Thought

redOrbit Staff & Wire Reports — Your Universe Online The mass of the Milky Way is approximately 20% larger than previously believed, scientists from the National Astronomical Observatory of Japan (NAOJ) have discovered. The NAOJ team, led by associate professor Mareki Honma, used measurements from radio telescopes, including Japan's VLBI (Very Long Baseline Interferometry) Exploration of Radio Astrometry or VERA device, to determine that the distance from the sun to the center...

Planets Can Form In The Center Of Violent, Unstable Galaxies

April Flowers for redOrbit.com - Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. The center of the Milky Way seems like the last place to form a new planet, inhospitable and violent even. Stars crowd each other, whizzing through space like cars on a rush hour freeway while supernova explosions blast out shock waves and bathe the region in intense...

April Flowers for redOrbit.com — Your Universe Online A team of astrophysicists from the Center for Astrophysics at the University of Notre Dame are exploring a discrepancy between the amount of lithium predicted by the standard models of elemental production during the Big Bang and the amount of lithium observed in the gas of the Small Magellanic Cloud. The Small Magellanic Cloud is a dwarf galaxy with a diameter of about 7,000 light-years.  It contains several hundred...

When Star Clusters Collide: Hubble
2012-08-16 15:08:22

Watch the Video: Simulation of Star Clusters Encounter Lee Rannals for redOrbit.com - Your Universe Online The Hubble Space Telescope has been keeping its eyes fixed on two clusters full of massive stars that may be in the early stages of merging. The star clusters are about 170,000 light-years away in the Large Magellanic Cloud, which is a small satellite galaxy to our Milky Way. What was thought to have been just one cluster in the star-forming region commonly referred to as the...

Milky Way

Lee Rannals for redOrbit.com - Your Universe Online Astronomers from Canada and the U.S. have found that the Milky Way galaxy may have recently had an encounter with one of its surrounding smaller satellite galaxies. “We have found evidence that our Milky Way had an encounter with a small galaxy or massive dark matter structure perhaps as recently as 100 million years ago,” Larry Widrow, professor at Queen´s University in Canada, said in a press release. “We...

Milky Way Galaxy -- The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia (gala, galactos means "milk")) is a hazy band of white light across the night sky formed by billions of stars in the disc of our galaxy. The Milky Way appears brightest in the direction of Sagittarius, where the galactic centre lies. Relative to the celestial equator, the Milky Way passes as far north as the constellation of Cassiopeia and as far south as the constellation of...
