Many large heavenly bodies and events in the universe, such as the birth and death of stars, generate energy in different wavelengths of light, which existing telescopes can find, says Nergis Mavalvala, the Curtis and Ka...

Astronomers have studied the carbon monoxide in a galaxy over 12 billion light years from Earth and discovered that it's running out of gas, quite literally, and headed for a 'red and dead' future.

Asteroid and comet impacts could have destroyed some habitats for life while also creating new ones for bacteria --

On 12 July, 10 August and 9 September 2014, a full moon will occur when the satellite is closest to Earth in orbit. Called a 'perigee moon' its brightness is increased and size enlarged due to proximity to Earthbound sky...

An M6-class flare erupted from sunspot AR2113 on June 8th, 2014. NASA's Solar Dynamics Observatory captured the fireworks in multiple wavelengths.

The vast reaches of empty space between galaxies are bridged by tendrils of hydrogen and helium, which can be used as a precise "light meter." In a recent study published in The Astrophysical Journal Letters, a team of s...

Last week, we encouraged those of you with a decent sized backyard telescope (and a little patience) to try and spot tiny dwarf planet Pluto. One of our favorite astrophotographers, John Chumack, did just that using the ...

The 30-minute webcast, which is called "Spotlight Live: The Hunt for Other Worlds Heats Up," begins at 3:00 p.m. EDT Wednesday. You can watch it live here on Space.com, courtesy of the nonprofit Kavli Foundation, which i...

A NASA probe recently spotted the dazzling Pan-STARRS comet as it hurtled through space against the backdrop of a distant galaxy.

'Tis the season once again, when rogue Full Moons nearing perigee seem roam the summer skies to the breathless exhortations of many an astronomical neophyte at will. We know... by now, you'd think that there'd be nothing...

Processes that shaped the ridges and troughs on the surface of Jupiter's icy moon Ganymede are likely similar to tectonic processes seen on Earth, according to a team of researchers led by Southwest Research Institute (S...

People on the main island of Japan are preparing to get hit by the strongest cyclone the Western Pacific has seen in the 2014 season: Typhoon Neoguri. It has already passed over Okinawa, and its 190 kilometer per hour (1...

NASA Breaking News: NASA's James Webb Space Telescope has reached another development milestone with the completion of static load testing of its primary mirror backplane support structure (PMBSS) moving the telescope on...

Something is amiss in the Universe. There appears to be an enormous deficit of ultraviolet light in the cosmic budget.

NASA's Goddard Space Flight Center: Atmospheric physicist Ralph Kahn works with a brilliant climate change community, from the national to international level.

NASA's James Webb Space Telescope has reached another development milestone with the completion of static load testing of its primary mirror backplane support structure (PMBSS) moving the telescope one step closer to its...

Carnegie Institution for Science: Pasadena, CA--Something is amiss in the Universe. There appears to be an enormous deficit of ultraviolet light in the cosmic budget. The vast reaches of empty space between galaxies are ...

Astronomers have created a detailed 3D model of the expanding cloud of debris produced in the outburst of a doomed star. The model can be reproduced at home by anyone with a 3D printer. The team report their findings in ...

Royal Astronomical Society: Astronomers have created a detailed 3D model of the expanding cloud of debris produced in the outburst of a doomed star. The model can be reproduced at home by anyone with a 3D printer. The te...

While Hurricane Arthur was still a hurricane, the new Global Precipitation Measurement (GPM) Core Observatory flew over the storm last week and captured its structure in 3-D. This was a good test of the new satellite, wh...

Global warming is real, and we're starting to feel the physical effects now. It's difficult to pin any one event on a warming world; it's like playing craps with a pair of loaded die. That 12 you rolled may have been ran...

Astronomers have found a "hotspot" beneath the Big Dipper emitting a disproportionate number of the highest-energy cosmic rays. The discovery moves physics another step toward identifying the mysterious sources of the mo...
