An instrument that uses high-energy electrons to take “snapshots” of ultrafast chemical processes at the atomic and molecular level just got a major upgrade. Researchers have conducted the first experiment using a new detector, installed in the megaelectronvolt ultrafast electron diffraction (MeV-UED) instrument, at the Linac Coherent Light Source (LCLS) at the Department of Energy’s […]
In Dante’s “Divine Comedy,” Hell is described as an “inferno” with nine concentric circles, the entrance of which has a sign that reads “Abandon all hope, ye who enter here.” For the planets of the solar system, Venus is about as close to this description as one can get. On the surface, temperatures are hot […]
For the first time in more than half a century, astronauts will fly around the moon on Monday, marking the high point of the Artemis 2’s lunar mission.

The Artemis astronauts entered the final phase of their run-up to a lunar loop on Monday, a tipping point of sorts that means the moon’s gravity is now having a stronger pull on the spacecraft than Earth’s.

The four astronauts on NASA’s Artemis 2 mission began their fifth day journeying to the moon on Sunday, after already taking in sights of the lunar surface never before seen by human eyes.

A team of US astronomers has carried out one of the deepest analyses to date of a sample from the asteroid Bennu, revealing new details about how water and organic material interacted during the earliest stages of the solar system.

Designed to hunt for new alien worlds, NASA’s Transiting Exoplanet Survey Satellite (TESS) has serendipitously observed the rising outburst of a black hole X-ray binary known as AT 2019wey. The observations, which may help us better understand the nature of this system, were presented March 25 on the arXiv pre-print server.

For some time, astronomers have theorized that there is a connection between planetary mass and rotation. In the solar system, Jupiter and Saturn both rotate rapidly, completing a rotation in roughly ten hours, while accounting for a significant fraction of the solar system’s rotational energy. Using the W.M. Keck Observatory on Maunakea, Hawai’i, a team […]
This image captured by U.S.-Indian Earth satellite NISAR on Nov. 10, 2025, shows Washington’s Mount St. Helens. The image is cropped from a much larger swath spanning the Pacific Northwest on a cloudy day; NISAR’s L-band SAR instrument is able to peer through the clouds at the surface below.

More than 50 years after humans first flew around the moon, Artemis astronauts will repeat the feat on Monday and use the most basic instrument to study it: their eyes.

The early universe is absolutely so far outside our understanding of how the world works it’s hard to describe in words. Back then, the cosmos wasn’t filled with stars and galaxies but with a boiling soup of quarks and gluons, with a few microscopic black holes thrown in, occasionally detonating like depth charges. That’s the […]

The Artemis astronauts have taken in sights of the moon never before seen by human eyes, crew members reported on Sunday as their spacecraft crossed the two-thirds mark on their journey to a long-anticipated lunar flyby.
