Mars once looked far more like Earth, with a thicker atmosphere and liquid water pooling on its surface, yet today it is a frozen desert where even a thin wisp of air struggles to hold on. NASA’s latest mission aims to catch the planet in the act of losing what remains of that air,

Scientists have been fascinated by the third interstellar object to ever known to visit our solar system that is revealing more and more surprising secrets.

New 3I/ATLAS images from NASA and the ESA suggest the interstellar comet is active as it approaches Earth in December.

New Hubble images show the interstellar object in detail, amid claims by Harvard astrophysicist Avi Loeb that 3I/ATLAS could be more than a comet.

WASHINGTON, Dec 17 - The U.S. Senate on Wednesday confirmed billionaire private astronaut Jared Isaacman to become President Donald Trump's NASA administrator, making an advocate of Mars missions and a former associate of SpaceX CEO Elon Musk the space agency's 15th leader.

MAVEN (Mars Atmosphere and Volatile EvolutioN) is one of only three NASA missions currently in operation around Mars, and one of five spacecraft serving as a communications relay for the space agency's rover missions on the Martian surface.

Hubble images of interstellar object 3I/ATLAS reveal a sunward anti-tail, showing a teardrop-shaped coma with separated non-volatile objects, as reported by Avi Loeb and NASA observations.

The James Webb Space Telescope (JWST) has once again spotted a distant exoplanet that I have exactly zero interest in visiting. The ultrahot super-Earth, descriptively named TOI-561 b, is surrounded by a thick blanket of hot gas that churns above a broiling magma ocean. Fun!

NASA’s new ESCAPADE mission is set to uncover the mysteries of Mars’ atmospheric loss, offering crucial insights into how the planet evolved from a potentially habitable world to the dry, barren landscape we see today.
