Researchers have developed a new method using the Allen Telescope Array to search for interplanetary radio communication in the TRAPPIST-1 star system.

A new technique allows astronomers to home in on planets beyond our solar system that are in line with each other and with Earth to search for radio signals similar, for example, to ones used to communicate with the rovers on Mars...

The NASA/ESA Hubble Space Telescope has provided a dramatic and colorful close-up look at one of the most rambunctious stars in our galaxy, weaving a huge spiral pattern among the stars. Hubble’s images capture its details and its evolution is featured by a unique timelapse video.

Residing only roughly 700 light-years from Earth in the constellation Aquarius, R Aquarii is a symbiotic binary star: a type of binary star system consisting of a white dwarf and a red giant that is surrounded by a large, dynamic nebula. As the closest symbiotic star to Earth, R Aquarii was studied by none other than Edwin Hubble in an effort to understand the mechanism that powers the system.

R Aquarii undergoes violent eruptions that blast out huge filaments of glowing gas...

The OSIRIS-REx project made history last year as the first U.S. mission to bring back an asteroid sample from space—and with it came a treasure trove of data. An international collaboration, led by Sandia National Laboratories and including researchers at Los Alamos National Laboratory, has published a study in The Planetary Science Journal that reveals the preliminary findings from the capsule’s reentry.

The return of the OSIRIS-REx capsule was the largest geophysical observation campaign of its kind. “This project was a unique opportunity for us to observe the geophysical signals produced by a meter-sized object traveling at hypersonic speeds,” said Chris Carr, the lead author at Los Alamos National Lab...

A NASA spacecraft is ready to set sail for Jupiter and its moon Europa, one of the best bets for finding life beyond Earth.

Europa Clipper will peer beneath the moon’s icy crust where an ocean is thought to be sloshing fairly close to the surface. It won’t search for life, but rather determine whether conditions there could support it. Another mission would be needed to flush out any microorganisms lurking there.

“It’s a chance for us to explore not a world that might have been habitable billions of years ago, but a world that might be habitable today—right now,” said program scientist Curt Niebur.

Its massive solar ...
