With this instrument, researchers will make a deep-space map of where galaxies lie to s...

When the LIGO collaboration first detected the spacetime ripples of a gravitational wave it came from the merger of two black holes. To date, scientists have detected at least ten pairs of black holes spiraling into and combining with each other. But there’s still an outstanding mystery about these singularities: why are some of them so big? Some have been far larger than scie...

This spacecraft will detect if exoplanet skies are cloudy, hazy, or clear

NASA announced last week that it will contribute to a European Space Agency mission scheduled to launch in 2028. The spacecraft, called ARIEL (for Atmospheric Remote-sensing Infrared Exoplanet Large-survey), will be the first space mission dedicated to studying exoplanet atmospheres.During its primary mission lasting some four years, ARIEL will study the atmospheres of roughly 1,0...

How could we find a wormhole hiding in the Milky Way?

If there was a wormhole in the center of our galaxy, how could we tell? Two physicists propose that carefully watching the motions of a star orbiting the Milky Way's supermassive black hole might help scientists start to check. The researchers published the idea in a recent paper in the journal Physical Review D. A wormhole is a hypothetical concept that connec...
