The moss was attached to the International Space Station, fully exposed to the harsh environment of the cosmos. Not only did the spores endure, but they could still reproduce after returning to Earth.

The object is the third interstellar visitor to our solar system ever confirmed. It will reach its closest point to Earth next month.

Trump originally announced Isaacman as his pick in December 2024, then pulled the nomination five months months later.

A supermassive black hole violently gobbled up an enormous star, producing a gargantuan cosmic outburst, according to a new study.

Musk's company is behind schedule in developing its Starship rocket. NASA's interim leader, meanwhile, wants to put astronauts on the moon while Trump is in office.

The Australian Space Agency said the object "is likely a propellant tank or pressure vessel from a space launch vehicle."

China aims to put its astronauts on the moon by 2030. For NASA to get back there first, it needs SpaceX to quickly complete its Starship rocket — but it faces major hurdles.

The director of the California lab said the layoffs — around 10% of the JPL workforce — aren't a result of the government shutdown.

Maricopa County, Arizona, and Clark County, Nevada, offer a cautionary tale about what it takes to keep people alive in extreme temperatures.

The comets can be seen from the Northern Hemisphere as their orbits take them through our cosmic backyard. Two such appearances in the same month are uncommon.

Interstellar comet 3I/ATLAS is just the third such object ever confirmed to have entered our solar system. It has attracted intense interest among astronomers and amateur enthusiasts.

Temperatures across the region are expected to be up to 30 degrees higher than normal Friday and Saturday.

A paper from several NASA scientists and other researchers explores whether an asteroid with a 4% chance of hitting the moon in 2032 should be deflected or blown up.

The city of Mathis typically pumps its drinking water from Lake Corpus Christi, but worsening drought conditions are expected to plunge water levels too low to safely extract usable water.

This type of transformation is a hallmark of climate change, as rising temperatures and melting ice reshape landscapes in dramatic ways.

The potential “biosignature” isn’t direct evidence of life itself, but rather a leftover sign that textural features on the rock may have biological origins.

That raises the possibility that the TRAPPIST-1e exoplanet could also have liquid water and therefore support life.

Acting NASA administrator Sean Duffy also told agency employees not to let "safety be the enemy of progress."

The bottom of the hull was largely intact, but the sides of the 137-foot ship had split open — likely due to 138 years of being battered by wind, waves and ice.
