NuSTAR Helps Unravel The Mystery Of How A Dead Star Can Power Intense Gamma Rays

Whitney Clavin, Jet Propulsion Laboratory Our Milky Way galaxy is littered with the still-sizzling remains of exploded stars. When the most massive stars explode as supernovas, they don't fade into the night, but sometimes glow ferociously...

ESA’s Fly-eyed Telescope To Spot Risky Asteroids
2014-09-11 03:56:39

ESA Spotting Earth-threatening asteroids is tough partly because the sky is so big. But insects offer an answer, since they figured out long ago how to look in many directions at once. As part of the global effort to hunt out risky celestial objects such as asteroids and comets, ESA is developing an automated telescope for nightly sky surveys. This telescope is the first in a future network that would completely scan the sky and automatically identify possible new near-Earth...

fishing for galaxies

Whitney Clavin, NASA Jet Propulsion Laboratory A new survey of galaxies by NASA's Spitzer Space Telescope is taking a plunge into the deep and uncharted waters of our cosmos. In one of the longest surveys the telescope will have ever performed, astronomers have begun a three-month expedition trawling for faint galaxies billions of light-years away. The results are already yielding surprises. "If you think of our survey as fishing for galaxies in the cosmic sea, then we are finding...

Pleiades

Dave Finley, National Radio Astronomy Observatory Astronomers have used a worldwide network of radio telescopes to resolve a controversy over the distance to a famous star cluster -- a controversy that posed a potential challenge to scientists' basic understanding of how stars form and evolve. The new work shows that the measurement made by a cosmic-mapping research satellite was wrong. The astronomers studied the Pleiades, the famous "Seven Sisters" star cluster in the constellation...

Chuck Bednar for redOrbit.com - Your Universe Online An eruption of dust around a young solar-analog star discovered using the Spitzer Space Telescope could be the type of massive collision between asteroids that ultimately result in the formation of planets, astronomers report in Thursday’s online edition of the journal Science. Scientists began tracking the star in question, identified as NGC 2547-ID8, after it first surged with a large amount of fresh dust between August 2012 and...

WASHINGTON, Aug. 28, 2014 /PRNewswire-USNewswire/ -- NASA's Spitzer Space Telescope has spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of planets. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Scientists had been regularly tracking the star, called NGC 2547-ID8, when it surged with a huge amount of fresh dust between August 2012 and January 2013. "We...

firestorm of star birth

NASA/Space Telescope Science Institute/ESA Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed “Sparky,” is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate. The discovery was made possible through combined observations from NASA’s Hubble and Spitzer space telescopes, the W.M. Keck Observatory in Mauna Kea, Hawaii, and the European Space...

extreme ultraviolet light activity on the sun

April Flowers for redOrbit.com - Your Universe Online As children, we are told never to look directly at the Sun, especially through the lens of a camera, telescope or magnifying glass. Even if a person used the special filters that would allow them to gaze at the Sun, they would not be able to see all of the wavelengths of light emanating from the Sun. To fully understand our star, scientists must use spacecraft that can observe this invisible light before it is absorbed by the...

supermassive black hole

April Flowers for redOrbit.com - Your Universe Online An extreme and rare event in the region of space immediately surrounding a supermassive black hole has been captured by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. The corona of the black hole, a compact source of X-rays that is situated nearby, has moved closer to the black hole over a period of just days. "The corona recently collapsed in toward the black hole, with the result that the black hole's intense gravity...

Alan Buis and Steve Cole, NASA Just over a month after launch, the Orbiting Carbon Observatory-2 (OCO-2) -- NASA's first spacecraft dedicated to studying atmospheric carbon dioxide -- has maneuvered into its final operating orbit and produced its first science data, confirming the health of its science instrument. Atmospheric carbon dioxide is the leading human-produced greenhouse gas responsible for warming our world. It is a critical natural component of Earth's carbon cycle. OCO-2...

Whitney Clavin, Jet Propulsion Laboratory NASA's Spitzer Space Telescope has received the 2014 AIAA Space Science Award for its ongoing infrared studies of the hidden cosmos. The American Institute of Aeronautics and Astronautics, or AIAA, a society for the field of aerospace engineering, established the award in 1961 for "individuals demonstrating leadership of innovative scientific investigation associated with space science missions." Michael Werner, the project scientist for Spitzer...
