The DART spacecraft has purposefully crashed into the asteroid Dimorphos, hopefully changing its orbit by a few minutes, in a milestone test of future planetary defense techniques
A new potential rule from the U.S. Federal Communications Commission would set a five-year deadline for defunct satellites to be removed from space
The James Webb Space Telescope’s first images of the distant universe shocked astronomers. Is the discovery of unimaginably distant galaxies a mirage or a revolution?
Seismology has been a long-overlooked tool in planetary exploration, but the success of NASA’s InSight lander has reignited the field
The suits, supplied by Axiom Space and Collins Aerospace, will be used in NASA’s upcoming Artemis lunar missions and will protect space travellers from micrometeoroids, moon dust and even vomit...
Russia’s invasion of Ukraine ended hopes of launching the ExoMars rover in 2022. Now the mission may never lift off at all
After delivering extraterrestrial samples to Earth in 2023, OSIRIS-REx will embark on an extended mission to a potentially planet-threatening space rock
Scientists are beginning to dream of how a new generation of super-heavy-lift rockets might enable revolutionary space telescopes and bigger, bolder interplanetary missions

Weighing in at seven times the mass of our sun, the dark object is by far the best-yet candidate for a free-floating stellar-mass black hole
Kepler-1708 b-i appears to be a giant moon orbiting a Jupiter-sized planet thousands of light-years from Earth
Independent concepts from each nation envision launching high-speed spacecraft on aspirational multigenerational voyages into the great unknown of interstellar space
With a density close to that of pure iron, GJ 367b may be the remnant metal-rich core of an evaporated giant world
A privately funded telescope called Toliman will seek habitable worlds in our nearest neighboring star system, potentially sparking a new wave of exoplanetary exploration
Sparked by major advances in their field, astrobiologists are grappling with how best to discuss possible breakthrough discoveries with the public
New results from the mission reveal that its landing site of Jezero Crater has a surprisingly dynamic and complex hydrologic history
Although our sun is considered a quiet star, it is now thought to have repeatedly pelted our planet with enormous eruptions in the not too distant past. Could another occur in the near future?...
The NASA mission used seismic waves from marsquakes to perform a core-to-crust survey of the planet’s subsurface
The huge object may be the biggest comet ever seen. And it is already showing signs of activity as it approaches the orbit of Saturn
