Scientists Make The Most Precise Measurment Of Early Universe Yet

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...

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
2013-09-24 10:15:41

[ 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
2013-09-14 03:38:45

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...

Mapping The Skies In 3D Gets Help From University Of Colorado
2013-06-26 13:16:46

Brett Smith for redOrbit.com - Your Universe Online The University of Colorado has announced it is becoming a full partner of the Sloan Digital Sky Survey-IV (SDSS-IV), looking to help in efforts to map the entire sky in three dimensions. The program began in 2000 and has currently mapped about 50 percent of the visible northern sky in three dimensions. In the process of creating this map, the project has identified almost 500 million astronomical objects, including asteroids, stars,...

University Of Utah Joins Sky Survey’s Fourth Phase With W.L. Eccles Grant
2013-06-25 12:01:02

University of Utah University of Utah astronomers will participate in a six-year project to study the formation of our Milky Way galaxy; map stars, gas and supermassive black holes in 10,000 neighbor galaxies; and chart 1 million galaxies and quasars to learn about mysterious “dark energy” that makes the universe expand. Five years after joining the third phase of the Sloan Digital Sky Survey, or SDSS-III, Utah’s largest research university is signing up for the fourth phase of...

Stellar Patrons Of The Milky Way Bar Identified By Astronomers
2012-12-19 15:03:31

SDSS-III Forget the restaurant at the end of the Universe – astronomers now have the clearest understanding yet of the bar at the center of the Milky Way. Scientists with the Sloan Digital Sky Survey III (SDSS-III) have announced the discovery of hundreds of stars rapidly moving together in long, looping orbits around the center of our Galaxy. "The best explanation for their orbits is that these stars are part of the Milky Way bar," says David Nidever, a Dean B. McLaughin Fellow...
