A NASA Mars orbiter recently spotted the Curiosity rover driving across the Red Planet's surface, capturing an unprecedented off-Earth action shot.

About 380,000 years after the Big Bang, the first atoms formed. The first light of what we now see as the cosmic microwave background was released, and the primordial hydrogen and helium grew cold and dark. The cosmos entered a dark age for about 100 million years until the first stars and galaxies started to form. You could say the rise of galaxies marked cosmic morning. But star formation didn't really kick into gear for another 2-3 billion years, during what astronomers call cosmic noon. This period can be difficult to observe, but a new study gives us an unprecedented view of this epoch.

Thirty-five years ago today, the Hubble Space Telescope was launched into Earth orbit.

Nobody knows it, but the universe has a secret smile, and it uses it only for Earth.

The Milky Way has more than 30 known satellite galaxies. The Large and Small Magellanic Clouds are the largest and most well-known; other lesser-known ones, like the Sagittarius Dwarf Galaxy, are also on the list. Astronomers think there are many more small satellites that are difficult to detect but essential in understanding the Milky Way. The Vera Rubin Observatory should help astronomers find many more of them.

Super-Earths can exist in wider orbits around their parent stars than was previously believed, suggesting these Earth-like exoplanets could be more common than we thought.

The three astronauts of China's Shenzhou 20 mission arrived at the nation's Tiangong space station today (April 24), about 6.5 hours after lifting off.

The first public look at Predator: Badlands has finally arrived, and it's safe to say this new entry is doubling down on the series' sci-fi worldbuilding.

Using the James Webb Space Telescope, astronomers have peered into galaxies that existed at cosmic noon to hunt ravenously feeding black holes and bursts of starbirth.

We associate complex chemistry with planets or other bodies, where energy and matter interact in dynamic associations. But as science advances, researchers are finding prebiotic chemistry in a wider variety of places, including in space itself. New research shows that some prebiotic chemicals, part of the recipe for life itself, can form in the cold vacuum of space.

Despite a rocky start, Ubisoft Massive is nowhere near done with Star Wars Outlaws. Next up, Kay and Nix will meet infamous pirate Hondo Ohnaka.

I do love the names of the European Southern Observatory installations. You are familiar I’m sure with the Very Large Telescope but have you heard of the Overwhelmingly Large Telescope? It was intended to house a 100m mirror but never got commissioned due to its complexity. There is however, an Extremely Large Telescope with a 39 metre mirror and its due to be completed in a couple of years. This image was taken on 12 April 2025 by photographer Eduardo Garcés showing its progress.

Astronauts repaired and upgraded NASA's Hubble Space Telescope over the course of five servicing missions from 1993 to 2009. Could yet another astronaut visit be in the cards?

Occasionally, the Universe seems to literally smile upon us. If skies are clear Friday morning on April 25th, early rising sky watchers may witness a rare scene, as brilliant Venus and fainter Saturn form the ‘eyes’ and a thin crescent Moon nearby completes the ‘grin’ low to the east at dawn.

For the first time, scientists have identified climate change as the top driver of human-caused biodiversity loss among species protected under the Endangered Species Act.

A powerful new instrument added to the Daniel K. Inouye Solar Telescope promises to maximize the information gleaned from the sun's light.

Here are the best star projectors to enjoy a night-sky experience from the comfort of your couch. The prices are often reduced on special occasions, such as Amazon Prime Day, so keep your eyes open.

To mark the 35th anniversary of the Hubble Space Telescope, Space.com looks at some of the most scientifically significant images that have emerged from the observatory's lens.

ESA's Biomass mission is on the launch pad at Europe’s Spaceport in Kourou, French Guiana. Don’t miss the live coverage of liftoff on Tuesday 29 April, on ESA WebTV. Coverage will start at 10:55 CEST with commentary live from Kourou and ESA’s European Space Operations Centre in Germany. The Vega-C rocket carrying Biomass is scheduled for liftoff at 11:15.

By teaming up with the James Webb Space Telescope, or by scientists delving into its long history of observations, Hubble is cementing its legacy.
