In the Milky Way there's a single X-ray binary -- a system consisting of a black hole capturing and heating material from an orbiting companion star -- known as Cygnus X-1. But 30 million light-years away in the Whirlpoo...

A prestigious panel of scientists recommends sending humans to the red planet as the space agency's wisest long-range goal --

SpaceX president respondedto nagging questions about the company's ability to keep pace with its growing launch manifest.

Scientists recently upgraded the Atacama Large Millimeter/submillimeter Array (ALMA) by installing an ultraprecise atomic clock at ALMA's Array Operations Site, home to the observatory's supercomputing correlator. This u...

In a discovery decades in the making, scientists have detected the first of a "theoretical" class of stars first proposed in 1975 by physicist Kip Thorne and astronomer Anna ytkow. Thorne- ytkow objects (T Os) are hybrid...

The five brightest planets of the night sky, Mercury, Venus, Mars, Jupiter and Saturn, can be a dazzling sight to see in the June sky, but only if you know when and where to look. Here's a look at the most amazing planet...

What is it like to make contact with a 36-year old dormant spacecraft? "The intellectual side of you systematically goes through all the procedures but you really end up doing a happy dance when it actually works," Keith...

Intense light from the enormous explosion of a star more than 12 billion years ago -- shortly after the Big Bang -- recently reached Earth and was visible in the sky. Known as a gamma-ray burst, light from the rare,...

A galactic cluster four-way collision has been recorded 5 billion light-years distant, an event previously unseen by astronomers.

Astronomers studying two classes of black-hole-powered galaxies monitored by NASA's Fermi Gamma-ray Space Telescope have found evidence that they represent different sides of the same cosmic coin. By unraveling how these...

One has never been spotted for sure in the wild jungle of strange stellar objects out there, but astronomers now think they have finally found a theoretical cosmic curiosity: a Thorne-Zytkow Object, or TZO, hiding in the...

Waves on Saturn's largest moon indicate methane seas—a potential home to alternative forms of life --

Waves on Titan indicate bodies of liquid methane may be home to life --

SpaceX's three-core Falcon Heavy rocket is a mega-booster that would be the largest, most powerful launch vehicle since NASA's Saturn V moon rocket. Here's how SpaceX's Falcon Heavy rocket works.

Severe space weather events from common red dwarf stars could doom any chances for life on planets orbiting those stars, scientists say. That may mean that alien life might be rarer than previously thought.

(Phys.org) --Supernovas are often thought of as the tremendous explosions that mark the ends of massive stars' lives. While this is true, not all supernovas occur in this fashion. A common supernova class, called Type Ia...

Lawrence Berkeley National Laboratory: A new study of supermassive black holes at the centers of galaxies has found magnetic fields play an impressive role in the systems' dynamics. In fact, in dozens of black holes surv...

A new study of supermassive black holes at the centers of galaxies has found magnetic fields play an impressive role in the systems' dynamics. In fact, in dozens of black holes surveyed, the magnetic field strength match...

Y'know, back in May when I said that I had nothing to add to Stephen Colbert's takedown of anti-vaccine nonsense, I'm glad the folks at The Daily Show didn't listen. Because this: There's some truth in this segment; anti...

Double star systems in the night sky can be spotted in binoculars and telescopes if you know where to look. See how 'starhopping' can help lead the way.

The following is a statement from NASA regarding the National Research Council report, "Pathways to Exploration - Rationales and Approaches for a U.S. Program of Human Space Exploration."

NASA is seeking proposals from universities to advance the agency's plans for exploration to deep space and Mars. The Early Stage Innovations NASA Research Announcement calls for innovative space technology proposals tha...
