Watch the Sept. 21 partial solar eclipse live online with this handy livestream. Coverage begins at 2 p.m. EDT (1800 GMT).
After decades of relying on aging satellites, NOAA is launching a purpose-built eye on the sun.
This limited-time deal gets you the Sony A7 III for just $1498 ahead of Amazon Prime Day in October and the Harvest moon — but it ends in three days.
In a move that’s concerning astronomers and environmental groups alike, the Federal Communications Commission (FCC) has proposed reducing environmental oversight of space-based operations.
Astronomers have unveiled the most detailed 3D map ever made of stellar nurseries in our Milky Way galaxy.
A trio of missions are on track to intercept and study the famous near-Earth asteroid Apophis during its close encounter with our planet in April 2029.
NASA's Curiosity Mars rover has been exploring the slopes of Mount Sharp looking for clues about Mars' watery past. Here, it looks at the boxwork pattern for ancient water flow.
I search for deals for a living and have been doing so for years. Below, I've rounded up the six best Lego deals Walmart is offering during its Bricktember event.
The discovery of a rare runaway galaxy suggests some isolated systems were shaped by past group interactions before being flung into solitude.
Hidden beneath the biggest ice mass on Earth, hundreds of subglacial lakes form a crucial part of Antarctica’s icy structure, affecting the movement and stability of glaciers, and consequentially influencing global sea level rise.
On these dark evenings the Perseus Double Cluster and the Andromeda Galaxy, M31, await in the northeast. They're only two fist-widths apart.

The age of exoplanets began in 1992, when astronomers detected a pair of planets orbiting a pulsar. Then, in 1995, astronomers discovered the first exoplanet orbiting a main sequence star. As NASA's Kepler and TESS missions got going, the number of confirmed exoplanets continued to rise.
In February 2016, scientists at the Laser Interferometer Gravitational wave Observatory (LIGO) announced the first detection of gravitational waves (GW). These ripples in space time, originally predicted by Einstein's Theory of General Relativity, are caused by the merger of massive objects (like neutron stars and black holes). Since then, gravitational wave observatories like LIGO, VIRGO, and the Kamioka Gravitational Wave Detector (KAGRA) have detected around 300 gravitational wave (GW) events.
A new program has discovered chaos in a nearby planetary system, which could explain the existence of a phenomenon astronomers call the hot-Neptunian desert.
Mysteriously powerful cosmic winds around neutron star may be 'game-changer' for understanding monster black holes
A remote solar eclipse ends the final season of 2025.
Before we get to Mars, we’re going to have to practice. And develop radical leaps in technology, but also practice. A Mars mission will be utterly unlike anything attempted by humanity. We’re talking about a group of settlers, maybe as few as an initial team of four, traveling over a hundred million miles away from home to a literally alien environment, one that is so hostile to life that nothing lives there, and turn it into a home.
In November 2019, Japan's Hayabusa 2 mission departed the asteroid Ryugu after 1.5 years of observations. It had successfully collected a sample from the near-Earth object and in December 2020, the spacecraft returned the valuable sample to Earth. If its mission had ended there, it would've been deemed one of the most successful and challenging missions ever conducted.
