A team of astronomers led by Carnegie's Meredith MacGregor and Alycia Weinberger detected a massive stellar flare--an energetic explosion of radiation--from the closest star to our own Sun, Proxima Centauri, which occurr...

Jupiter's icy moon Europa is a major target of astrobiology research as it offers a possible habitable environment. Under its 10 km-thick icy crust is an ocean of liquid water over 100 kilometers deep. Energy deriving fr...

NASA's new planetary protection officer is open to reexamining how the agency deals with both government and commercial missions to Mars and other potentially habitable worlds in the solar system. SpaceNews.com

The halo stars of our galaxy seem not to be randomly distributed in the halo - instead many are grouped together in giant structures - immense streams and clouds (or overdensities) of stars, some entirely encircling the ...

Michio Kaku tells Redditors his predictions about intelligent aliens.

"The discovery that these very bright objects, long thought to be black holes with masses up to 1,000 times that of the sun, are powered by much less massive neutron stars, was a huge scientific surprise," says Caltech's...

Astronomers have investigated a small population of stars in the halo of the Milky Way Galaxy, finding its chemical composition to closely match that of the Galactic disk. This similarity provides compelling evidence tha...

Where have all the planets gone? The end of February 2018 sees the three naked eye outer planets - Mars, Jupiter and Saturn-- hiding in the dawn. It takes an extra effort to brave the chill of a February morning, for sur...

In the 1980s, researchers began discovering extremely bright sources of X-rays in the outer portions of galaxies, away from the supermassive black holes that dominate their centers. At first, researchers thought these co...

Past, American waveriders had some critical flaws that the new Chinese design aims to solve.

Virgin Hyperloop One has released prototype for a levitating pod that is designed to zoom at speeds as high as 760 mph (1,200 km/h) through a Hyperloop connecting Dubai to Abu Dhabi, according to news sources.

Researchers have been testing the sub in a bucket-sized mock alien ocean in a lab.

The activity cycle of the sun - where the number of sunspots increase and decrease - has been monitored regularly for around 250 years, but the use of space-based telescopes has given us a whole new perspective of our ne...

Unistellar is proud to announce the first real scientific result obtained with our eVscope prototype. On Jan, 27, after designing a special observing mode for this purpose, we viewed an occultation of a magnitude-11 star...

National Radio Astronomy Observatory (NRAO): Space weather emitted by Proxima Centauri, the star closest to our sun, may make that system rather inhospitable to life after all. Using data from the Atacama Large Millimete...

On September 15th, 2017, after nearly 20 years in service, the Cassini spacecraft ended its mission by plunging into the atmosphere of Saturn. During the 13 years it spent in the Saturn system, this probe revealed a grea...

The NASA/ESA Hubble Space Telescope caught sight of a soft, diffuse-looking galaxy that is probably the aftermath of a long-ago galactic collision. Two spiral galaxies, each perhaps much like the Milky Way, swirled toget...

An amateur astronomer testing his new camera captures the moment a supernova became visible in the night sky, which has helped an international team of researchers to test their theory about the beginning stages of a ste...

Mission managers at NASA's Jet Propulsion Laboratory in Pasadena, California, this week lowered the orbit of the nearly 12-year-old CloudSat satellite following the loss of one of its reaction wheels, which control its o...
