New observations with the James Webb Space Telescope reveal the most distant pair of merging black holes ever spotted. The discovery further challenges leading theories of cosmology.

The strongest solar flare in half a decade just launched off the sun from the same sunspot group that triggered dazzling auroras last weekend. But don't expect northern lights this time around.

Coronal moss grows, solar rain falls and plasma eruptions rear their gargantuan heads in this fiery landscape of the sun's outer atmosphere, taken by ESA's Solar Orbiter.

The James Webb Space Telescope's possible detection of biological chemicals on the exoplanet K2-18b may just have been methane gas, a new study cautions. Planned follow-up observations could solve the mystery for good.

Fiery pink towers could be seen erupting from the sun during the total solar eclipse on April 8. What are they?

A solar eclipse viewing party at Canada's Royal Botanical Gardens peaked with a 90-second totality that blew minds and moved hearts. Also, there were geese.

It may not be too late to get last minute solar eclipse glasses for today, depending on your location.

A total solar eclipse will be visible to millions of people in North America today. Here's everything you need to know about where, when, and how to view the 2024 solar eclipse.

These 2024 solar eclipse maps will help you make the best decision about where and how to watch the total solar eclipse on Monday (April 8).

Two gargantuan structures discovered near our galaxy's ancient heart may be some of the earliest building blocks of the Milky Way. Researchers have named them Shiva and Shakti.

The Spring equinox (March 19, 2024) signals the start of spring in the Northern Hemisphere, the beginning of autumn in the Southern Hemisphere, and a rare moment of "equal night" across the world.

After enduring two weeks in the freezing lunar night, Japan's SLIM moon lander awoke long enough to snap some new pictures and communicate with researchers on Earth.

From a 'potentially hazardous' asteroid to a pair of galaxies unable to quell their attraction, here are five of the most beautiful heart-shaped objects seen in space.

Scientists using the eROSITA X-ray telescope have released a trove of data that reveals more than 900,000 objects in space, including 700,000 supermassive black holes and other 'exotic' objects.

The latest photos from NASA's immobile Ingenuity Mars helicopter reveal the extent of the rotor blade damage it sustained on its fateful 72nd flight.

NASA's Ingeunity helicopter has finally ended its three-year mission on Mars after sustaining irreparable rotor damage on its 72nd flight over the Red Planet. It was only designed to fly five times.

Japan's SLIM lander successfully reached the lunar surface on Friday, Jan. 19, but problems with its solar cells mean it could be dead on the moon within hours.

In the final hours of Dec. 31, 2023, the sun launched its most powerful solar flare in 6 years. On Jan. 2, radiation from the blast may bring auroras to Earth's skies.

Aliens made headlines in 2023, but are we really any closer to finding life beyond Earth? A recap of the best new evidence, and other remarkable stories from the year in space.

Halley's Comet was predicted to reach its farthest point from the sun on Dec. 9, beginning a 38-year journey toward Earth that culminates in 2061.

The James Webb Space Telescope has discovered a cosmic 'peanut' and 'fluff ball' that happen to be two of the four oldest galaxies in the known universe.

The James Webb Space Telescope has discovered a massive chain of 20 galaxies in the early universe, raising questions about the formation of the largest structures in the cosmos.

In the glare of the sun, an unknown number of near-Earth asteroids move on unseen orbits. A new generation of space telescopes could be our best defense against potential disaster.
