A recent image from the Hubble Space Telescope captures a gorgeous spiral galaxy bursting with new star formation.

An audacious NASA mission suggests that dust blown north from Greenland couldhelp explain why Arctic ice is melting even faster than expected.

Earlier this week, the Space Telescope Science Institute (STScI) announced the science objectives for the fourth cycle of the James Webb Space Telescope's (JWST) General Observations program - aka. Cycle 4 GO. In keeping with Webb's major science objectives, many of these programs will focus on the study of the earliest galaxies in the Universe.

Why are there so many cyclones around the north pole of Jupiter?

Ingenuity proved beyond a shadow of a doubt that a helicopter can operate on another planet. Over 72 flights, the little quadcopter that could captivated the imagination of space exploration fans everywhere. But, several factors limited it, and researchers at NASA think they can do better. Two papers presented at the recent Lunar and Planetary Science Conference, held March 10-14 in The Woodlands, Texas, and led by Pascal Lee of NASA Ames and Derric Loya of the SETI Institute and Colorado Mesa University, describe a use case for that still-under-development helicopter, which they call Nighthawk.

Know no fear brother, because 'Warhammer 40,000: Space Marine 3' is officially on the way.

Exploration of the outer Solar System may be getting a boost from the Vera Rubin Observatory (VRO). When this gigantic telescope opens its eye later in 2025, it begins a decade-long survey of the ever-changing sky. As part of this time-lapse vision of the cosmos, distant objects in the Kuiper Belt will be among its most challenging targets.

A NASA photographer captured a time-lapse image of the lunar eclipse and blood moon above the Space Environments Complex at NASA’s Glenn Research Center at Neil Armstrong Test Facility in Sandusky, OH on March 14, 2025.
