The Chicxulub asteroid impact that ended the dinosaur era left the site in what is now Mexico hot enough to sustain underground microbial life for at least 8 million years. New analysis of rock cores shows the hydrothermal system lasted far longer than earlier estimates suggested.

Nasa's Psyche spacecraft has used Mars' gravity to accelerate toward its target asteroid. The maneuver occurred on May 15 when the probe passed close to the planet.

New research has resolved a long-standing debate, confirming that the Silverpit Crater beneath the North Sea resulted from an asteroid strike about 43 to 46 million years ago. The impact generated a tsunami over 100 meters high. Led by Dr. Uisdean Nicholson of Heriot-Watt University, the study used seismic imaging and shocked minerals to provide definitive evidence.

Images from NASA's DART mission have provided the first direct visual evidence that asteroids in binary systems exchange material through slow-moving debris. Faint streaks on the asteroid moon Dimorphos suggest debris from its parent asteroid Didymos landed there, driven by sunlight-induced spin. This discovery highlights the dynamic nature of near-Earth asteroids.
