Curiosity rover provides new insights into how Mars became uninhabitable

This is an artist’s concept of an early Mars with liquid water (blue areas) on its surface. Ancient regions on Mars bear signs of abundant water – such as features…

Astronomers use Webb to probe a ‘steam world’ in the constellation Pisces

The study found that the planet’s atmosphere contains a high concentration of heavier molecules, including a significant amount of water vapor. Credit: NASA, ESA, Leah Hustak (STSCI), Ralf Crawford (STSCI)…

Astronomers detect multiple extended tidal tails in an old globular cluster

High-probability members of NGC 288’s tidal tails. The green points show stars lying along the trailing tail, the cyan points designate candidate stars in the inner leading tail, and yellow…

Nuclear rockets could travel to Mars in half the time, but designing the reactors that would power them isn’t easy

Traces of antimatter in cosmic rays reopen the search for ‘WIMPs’ as dark matter

The image shows the predicted flux of antihelium-3 produced from dark matter (WIMPs) that annihilate producing these antinuclei. Each color represents the prediction for a different mass of dark matter,…
