New maps pinpoint possible sites of the Red Planet's ancient seas and current underground reservoirs --

A primitive ocean on Mars held more water than Earth's Arctic Ocean, and covered a greater portion of the planet's surface than the Atlantic Ocean does on Earth, according to new results published today....

Researchers, including physicists from Heidelberg University, have gained new insights into dark energy and the theory of gravitation by analysing data from the "Planck" satellite mission of the European Space Agency (ES...

Ancient Mars likely once had an ocean large enough to cover 20 percent of the Martian surface, a fifth of the planet, scientists say. But over time, most of that water was lost to space.

The fastest-known star in the Milky Way is on a path out of the galaxy, and new research suggests it was a supernova that gave it the boot.

For the first time, a cosmic magnifying glass has allowed scientists to see the same star explosion four times, possibly offering a revealing glimpse into these explosive stellar deaths and the nature of the accelerating...

About 4.5 billion years ago, the Red Planet was a much wetter place. New isotopic measurements of Mars by several ground-based telescopes on Earth reveal a new map of where the water laid and a model of water loss over t...

New research reveals that a compact helium star that's traveling out of the Milky Way galaxy was once donating its mass as part of a type Ia supernova pair. The spin of the star increased dramatically over time leading t...

Albert Einstein's General Theory of Relativity celebrates its 100th anniversary in 2015. See the basic facts of Einstein's relativity in our infographic here.

Over the past several decades, astronomers have come to realize that the sky is filled with magnifying glasses that allow the study of very distant and faint objects barely visible with even the largest telescopes.

NASA's Jet Propulsion Laboratory News and Features: NASA's next mission to Mars, InSight, is on track to launch a year from today and to study the Red Planet's interior to learn about how rocky planets like Earth evolved...

The Indian Space Research Organisation (ISRO) will conduct its long-delayed initial test flight of a reusable launcher technology demonstrator by midyear. The post India To Fly RLV Tech Demo by June appeared first on Spa...

A patent board offered SpaceX a split decision on its protest of a reusable launch vehicle patent held by Blue Origin, approving a review of some, but not all, claims of that patent. The post SpaceX Gets "Partial Win" in...

Researchers wanting to know more about the influences of multiple stars on exoplanets have come up with a new case study: a planet in a four-star system....

A primitive ocean on Mars held more water than Earth's Arctic Ocean, according to NASA scientists who, using ground-based observatories, measured water signatures in the Red Planet's atmosphere.

"Nobody really understands how life got started on Earth," says Scott Sandford, a space science researcher at NASA Ames. "Our experiments suggest that once the Earth formed, many of the building blocks of life were likel...
