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...

NASA Asteroid Initiative
2014-02-13 07:01:17

NASA In June of last year, NASA Administrator Charlie Bolden spoke to the United Nations Committee on Peaceful Uses of Outer Space (COPUOS) and shared with the international community what NASA is doing to detect and track asteroids. He also engaged the United Nation’s support for NASA’s mission to find, capture and redirect an asteroid to lunar orbit, and then send humans to explore it by 2025. Following Bolden’s presentation, Mazlan Othman, director of the U.N. Office for Outer...

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...

Car-Sized New Year's Asteroid Enters Earth Over Atlantic Ocean
2014-01-03 11:11:33

[ Watch the Video: First Asteroid Of 2014 ] Gerard LeBlond for redOrbit.com - Your Universe Online According to NASA, the first asteroid of the 2014 season was discovered by Catalina Sky Survey, a NASA-sponsored observatory near Tucson, Arizona. It has been designated as 2014 AA and was viewed moving across the sky early Wednesday morning, January 1, 2014. The size of 2014 AA was estimated to be between seven and 10 feet and had the potential of striking Earth. The exact path of the...

Newly Discovered Asteroid Has Slight Chance Of Impacting Earth
2013-10-18 12:02:43

[ Watch the Video: Earth Receives A Quick Visit From Asteroid ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers working at the Crimean Astrophysical Observatory in Ukraine found a new asteroid on October 13, 2013 and NASA confirmed it came within about 4.2 million miles of Earth on September 16. While 4.2 million miles seems far enough away, experts said the rock, known as asteroid 2013 TV135, will have a slight chance of impacting Earth when it returns in 2032. While...

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...

Dark Energy Survey Will Look For Supernovae
2013-07-01 18:32:12

John P. Mills, Ph.D. for redOrbit.com - Your Universe Online The greatest cosmological puzzle of the 21st century continues to be to measure, characterize and understand the source of dark energy, the apparent force that is driving the accelerating expansion of the Universe. One of the problems is that in order to make accurate measurements of the expansion rate, astronomers must measure the motions of distant galaxies, some near the very edge of the known Universe. At such great...

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,...

Near-Earth Object -- Near-Earth Objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger. Due to their size and proximity, NEO's are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development. In fact, some near-Earth asteroids can be reached with much less ΔV (change in velocity) than the Moon. In the United States, NASA...

Cerro Tololo Observatory -- astronomical observatory located on Cerro Tololo peak, Chile, with offices in La Serena, about 40 mi (64 km) to the west. Funded by the U.S. National Science Foundation (NSF), it is operated by the Association of Universities for Research in Astronomy (AURA), which also operates such other major national observatories as the Kitt Peak National Observatory in Arizona. The principal instrument is a 158-in. (4-m) reflecting telescope, the largest in the...
