A chain of solar outbursts, including a "cannibal" coronal mass ejection that slammed Earth on Tuesday, will bring lovely auroras to parts of the northern US and most of Canada this weekend. Here's where to look.

To mark its second anniversary of operations, James Webb Space Telescope scientists share a stunning view of the Penguin and Egg galaxies as they slowly collide.

On Saturday (June 29), an asteroid larger than the Great Pyramid of Giza will fly past Earth at about three-quarters the distance from Earth to the moon. The asteroid, named 2024 MK, poses no risk to our planet.

Thousands of pieces of space debris, also known as space junk, are orbiting Earth, with tons more added each year. This orbital debris poses a significant threat to satellites, spacecraft, astronauts — and increasingly humans on Earth.

A gargantuan "exhaust vent" may be channeling hot gas away from the Milky Way's supermassive black hole at millions of miles per hour — and filling up two enormous bubbles that tower over the galaxy.

The James Webb telescope has spotted a peculiar group of baby stars firing enormous jets into space at nearly the exact same angle. The discovery could hold new insights into how stars are born.

Boeing's Starliner spacecraft successfully carried two NASA astronauts to space today (June 5) in the final test of the spacecraft's capabilities. Starliner is bound for the International Space Station.

The James Webb Space Telescope has detected the two earliest, most distant galaxies in the known universe, dating to just 300 million years after the Big Bang. The detection of even earlier galaxies is likely to follow.

The James Webb Space Telescope may have spotted the birth of some of the earliest galaxies in the universe for the first time ever, new research hints.

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).

With less than two weeks before the April 8 total solar eclipse in North America, it's time to get your certified solar eclipse glasses before they sell out. Just make sure you're buying from an approved vendor.

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.
