Black Hole With Minor Damage - Closest Near-Miss Event Ever To Be Spotted Near The Milky Way

Provided by Pam Frost Gorder, The Ohio State University Astronomers have gotten the closest look yet at what happens when a black hole takes a bite out of a star—and the star lives to tell the tale. We may think of black holes as...

Yue Shen, Carnegie Institution Quasars are supermassive black holes that live at the center of distant massive galaxies. They shine as the most luminous beacons in the sky across the entire electromagnetic spectrum by rapidly accreting matter into their gravitationally inescapable centers. New work from Carnegie’s Hubble Fellow Yue Shen and Luis Ho of the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University solves a quasar mystery that astronomers have been puzzling...

Astronomers Discover Nearly 200 Previously Unknown 'Red' Galaxies
2014-06-13 11:46:53

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online One of the greatest aspects of NASA’s astronomical research program is that the data accumulated from virtually all of the instruments – X-ray satellites, Infrared detectors, gamma-ray satellites – is available to the public. This means professional and amateur astronomers alike have the ability to make breakthrough discoveries. For instance, in 2007 Dutch school teacher Hanny van Arkel discovered a peculiar blob in an...

Scientists Make The Most Precise Measurment Of Early Universe Yet
2014-04-08 07:50:37

Lawrence LeBlond for redOrbit.com - Your Universe Online Two recent studies of the early Universe using the Baryon Oscillation Spectroscopic Survey (BOSS), a component of the third Sloan Digital Sky Survey (SDSS-III), have made the most accurate measurement of the rate of expansion in the early Universe to date. BOSS has pioneered the use of quasars to map density variations in intergalactic gas at high redshifts to trace the structure of the young Universe. BOSS helps scientists chart...

Collage of galaxies in the Herschel Reference Survey

ESA The largest census of dust in local galaxies has been completed using data from ESA’s Herschel space observatory, providing a huge legacy to the scientific community. Cosmic dust grains are a minor but fundamental ingredient in the recipe of gas and dust for creating stars and planets. But despite its importance, there is an incomplete picture of the dust properties in galaxies beyond our own Milky Way. Key questions include how the dust varies with the type of galaxy, and how...

Quasars Illuminate Swirling Clouds Around Galaxies
2014-01-09 08:49:42

University of Illinois at Urbana-Champaign A new study of light from quasars has provided astronomers with illuminating insights into the swirling clouds of gas that form stars and galaxies, proving that the clouds can shift and change much more quickly than previously thought. Led by University of Illinois at Urbana-Champaign astronomy professor Robert J. Brunner and former graduate student Troy Hacker (now with the U.S. Air Force), the astronomers published their findings in the...

One-Percent Accurate Measurement Of Universe Completed By BOSS
2014-01-09 09:02:10

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Baryon Oscillation Spectroscopic Survey (BOSS) announced on Wednesday that their project has measured the scale of the universe to an accuracy of one percent – precise measurements that will help astronomers in their search to determine the true nature of dark energy. “One-percent accuracy in the scale of the universe is the most precise such measurement ever made,” explained principal investigator David...

Galaxy Zoo 2 Project Citizen Scientists

[ Watch the Video: Galaxy Zoo 2 Project Crowdsourcing Catalogue ] Brett Smith for redOrbit.com - Your Universe Online With today’s modern telescopes collecting new data on the vast stretches of our universe at an unprecedented rate, astronomers are having a hard time keeping up. For help, an international group of researchers has turned to everyone’s favorite resource – the Internet. By enlisting over 83,000 volunteer citizen scientists online, researchers at the Galaxy Zoo 2...

Hubble Space Telescope

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Harvard-Smithsonian Center for Astrophysics (CfA) report that they have solved the mystery of why none of the unusually small galaxies known as “red nuggets” were seen nearby – they were essentially hiding in plain sight. These “red nuggets,” so named because of their miniature size and the fact that they are densely packed with stars of that color, had only been observed in the distant, young...

Las Cumbres Obsevatory Astronomy Imager Captures First Light
2013-08-02 09:25:02

Las Cumbres Observatory Las Cumbres Observatory Global Telescope (LCOGT), with first lights at nine new 1-meter telescopes since April of 2012, achieved another critical milestone by capturing the first on-sky image with a production Sinistro camera. In development for over six years, the camera is arguably more important than the telescopes that will use them. "A telescope is really nothing more than a large camera lens," explained Joe Tufts, instrumentation scientist on the Sinistro...

Exploring Hidden Milky Way
2013-08-01 08:48:11

John P. Millis, PhD for redOrbit.com - Your Universe Online Understanding how the Milky Way formed is one of the central scientific questions in astronomy. However, given the scale and complexity of the galaxy, there is a lot to consider. One of the ways researchers have found to tell the story of our galaxy's history is to create a detailed stellar census, analyzing spectra of large numbers of stars. "A star's spectrum is a powerful tool for learning about the star - it tells us key...
