While studying asteroid Bennu up close, NASA’s OSIRIS-REx spacecraft witnessed periodic outbursts of material being kicked up from the surface; a dedicated observation campaign revealed details of the activity.
New observations allowed astronomers to see, for the first time, the shadow of GW Orionis’ inner ring, which helped them figure out its 3D orientation.
New study provides the best estimate to date that bacteria could survive a trip to Mars.
Cosmic gas cloud blinks in sync with circling black hole.
New observations suggest that the unexpected dimming of the supergiant star was most likely caused by a dust cloud that blocked starlight coming from the star’s surface.

What is the maximum number of habitable planets for a star, and what does this mean in our search for extraterrestrial life?
In a rare occurrence, astronomers have directly observed more than one planet orbiting a star similar to the Sun.
Plate tectonics are important for habitability, and it appears that the optimum conditions existed for planets forming early in the galaxy’s lifespan … and may be unlikely to easily recur.
Research sheds new light on our hope of finding intelligent life across the galaxy.
