(Phys.org) --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 quic...

The supermassive singularity at the center of our galaxy (Sgr A*) flares in X-ray radiation every 5 - 10 days. Astronomers swing NASA's Swift XRT spacecraft to spy on the 4 million solar mass black hole every few days.

How did youthful galaxies in the early universe fatten up to become the behemoths we see today? One explanation, put forth more than a decade ago, is that galaxies in the early universe supped on... --

The LRO Diviner Lunar Radiometer has been mapping the entire Moon on a nearly continuous basis since July, 2009. The Diviner team has produced maps of the thermal behavior and and a range of derived quantities at Chang'e...

Today the Baryon Oscillation Spectroscopic Survey (BOSS) Collaboration announced that BOSS has measured the scale of the universe to an accuracy of one percent. This and future measures at this precision are the key to d...

The $100-billion International Space Station will be extended by four years, or until at least 2024, allowing for more global research and scientific collaboration, NASA said Wednesday.

Northerners thawing out from a bitter freeze may get rewarded with shimmering northern lights the next couple days.

Recent observations by NASA's Swift spacecraft have provided scientists a unique glimpse into the activity at the center of our galaxy and led to the discovery of a rare celestial entity that may help them test predictio...

The five Great Lakes, in all their glory, barely peak out from the veil of clouds and whooshing snowfall above them in a new satellite image captured Monday (Jan. 6) as the Arctic's polar vortex barreled southward.

NATIONAL HARBOR, Md.--More galaxies are separated by about 490 million light-years than by any other large distance, astronomers have found in the most precise measurement yet of this key cosmic... --

NASA and White House officials are announcing plans today (Jan. 8) to keep the International Space Station running through at least 2024 -- a four-year life extension for the largest spacecraft ever built.

An ultraprecise new galaxy map is shedding light on the properties of dark energy, the mysterious force thought to be responsible for the universe's accelerating expansion.

NASA announced today that the Obama administration has approved NASA’s request for an extension of operations for the International Space Station for an additional four years to 2024. This means work on board the orbit...

Lawrence Berkeley National Laboratory: The Baryon Oscillation Spectroscopic Survey (BOSS), the largest component of the third Sloan Digital Sky Survey, has measured the clustering of nearly 1.3 million galaxies spectrosc...

Right now, the Sun is sporting a huge sunspot called AR1944. It's grown in size over the past few days to a staggering 200,000 kilometers (125,000 miles) across. As I wrote the other day, sunspots are regions of intense ...

During its four-year mission, NASA's Kepler space telescope discovered thousands of "planetary candidates" in our Milky Way galaxy--the vast majority of which are almost certainly actual planets. But before scientists ca...

NASA's Goddard Space Flight Center: After a holiday break, final tests for the GPM Core Observatory resumed on Dec. 30, 2013, with alignment measurements. The spacecraft's instruments and components, such as star tracker...
