Suni Williams surpasses the most time by a woman on EVA during a spacewalk with Butch Wilmore outside the International Space Station.

Last year, 2024, was the warmest year on record for the planet, easily breaking the previous record set just a year earlier.

A NASA spacecraft has returned asteroid samples that hold not only the pristine building blocks for life but also the salty remains of an ancient water world.

Rock and dust samples from the Bennu asteroid contain molecules that are the "key to life" on Earth, NASA officials announced on Wednesday.

There are 20 amino acids that create the proteins required for life on our planet — and scientists have now found exactly 14 of them on an asteroid millions of miles away. The asteroid in question, named Bennu, was the focus of a very dreamy NASA mission called OSIRIS-REx that launched in 2016.

All forms of Earth life have specific chemicals in their makeup, such as amino acids and sugars. Scientists have known that asteroids hold molecules believed to be the precursors to these chemicals. By studying the Bennu samples, they hope to gain more insight into how these ingredients could have evolved.

Scientists say the unfolding El Niño event superimposed on long-term global warming is a primary driver of this huge spike in global surface temperatures since mid-2023. But the magnitude of the increase shocked many experts, leaving them somewhat puzzled about what else could be behind the remarkable temperature.

Molecules friendly to life have been found in samples of the asteroid Bennu, which NASA collected with a robotic probe five years ago.

Scientists from NASA and other institutions who have been analyzing the Bennu asteroid sample that returned to Earth last September found molecules, including amino acids, which are essential ingredients of life as we know it.

BS4 may be anywhere between 17 and 40 feet across, and will approach at about twice the distance between the Earth and moon.
