Scientists fret about the possibility of an asteroid hitting Earth with catastrophic consequences, just ask the dinosaurs.

NASA's 23-year-old Odyssey Mars orbiter is days away from celebrating an incredible milestone: 100,000 trips around Mars. To mark the record-setting occasion, NASA has released a new image of Olympus Mons, the tallest volcano in the solar system.

NASA's iconic Hubble Space Telescope has been going into protective "safe mode" after having issues with one of its three remaining gyroscopes forcing it to suspend science operations.

The James Webb Space Telescope (JWST) has been busy peering into the distant reaches of the Universe, otherwise known as the "Cosmic Dawn." This period when the Universe was only a few hundred million years old is a treasure trove of information about how galaxies evolved when the Universe was very young.

NASA has unveiled a new infrared camera that promises to drive impressive new science on Earth and beyond.

The many photos taken of the spectacular aurora lights that lit up the skies of North America and Europe last weekend will help NASA study solar storms for years to come.

Many conspiracy theories retain a foothold along the edges of society. Some of them are relatively innocent; others are downright dangerous. But few persist and propagate as effectively as conspiracies surrounding the Apollo 11 Moon landing.

NASA has released a fascinating flight map that charts all the Mars avigations taken by the space agency's recently defunct Ingenuity helicopter.

Following the journey of the James Webb Space Telescope and the brilliant minds who made it possible, Deep Sky is a new IMAX film hitting theaters tomorrow, April 19. PetaPixel chatted with one of these brilliant minds, NASA's Matt Mountain, who has worked on the Webb team since 2002.

NASA has been urged to offer its "advanced imaging technology" to help in a new search for the Loch Ness Monster.

NASA's Lunar Reconnaissance Orbiter (LRO) and the Korea Aerospace Research Institute's Danuri lunar orbiter crossed paths recently, and the former managed to snap a photo of the latter zipping past it at the relative velocity of 7,200 miles per hour.

In 1181, a supernova explosion appeared in the night sky for 185 days. Historical records show that the supernova, which some witnesses said looked like a "temporary star," shined as bright as Saturn in the constellation Cassiopeia.

As it used the last of its power reserves, the Intuitive Machines Odysseus Moon lander captured one final photo before shutting down.

The Sun has been very active so far this month, with powerful sympathetic solar flares dazzling scientists and viewers alike and recent X-class flares making many wonder about communications network integrity. NASA's Solar Dynamics Observatory (SDO) constantly monitors the Sun and captures the recent powerful solar flares in exquisite detail across multiple wavelengths.

The Odysseus moon lander, developed by Houston-based company Intuitive Machines, has sent incredible photos back to Earth. The private space exploration behind the lander has selected four to share with the world.

This week, NASA Goddard released a new video that highlights the Landsat program's achievements in 2023. A joint mission between NASA and the United States Geological Survey (USGS), satellite imagers have been orbiting Earth since Landsat 1 was launched in July 1972.

NASA engineers are working hard to resolve a critical issue with the Voyager 1 but communications with the longest-operating spacecraft in history may ultimately be lost.

A team from NASA's Goddard Space Flight Center has proposed a design for a lunar-based multi-camera telescope array that could start small, but expand to be much larger over time.

After greatly exceeding expectations and making dozens more trips into the Martian sky than planned, NASA's Ingenuity helicopter drone has made its final flight. Rest now, king.

Two powerful solar flares exploded nearly simultaneously on the Sun earlier this week, creating a spectacular and exceptionally rare sight.

NASA and the United States Postal Service (USPS) have teamed up on two new Priority Mail stamps that celebrate the James Webb Space Telescope (JWST/Webb).

While the James Webb Space Telescope has been busy helping scientists solve some of the greatest mysteries of the early Universe, the powerful telescope has also found that many distant galaxies have flattened oval disk and tube-like shapes, unlike the spiral and elliptical structures that are more typically seen in closer galaxies.

NASA has shared an image of a pair of galaxies that look like a penguin and its egg millions of light-years from Earth.

150 million light-years from Earth, a relatively small galaxy, UGC 5189A, was the site of a massive supernova, a super-powerful star explosion.
