The asteroid is estimated to be between 656 and 1,443 feet across, and will pass at 16 times the distance to the moon.

Alinda, measuring 2.6 miles wide, will be visible this weekend. Stargazers can spot it using basic equipment or watch a livestream. Events like this occur once in a decade.

On Monday night you may have a chance to witness the moon obscuring the Red Planet at its brightest, as well as a comet’s closest approach to the sun.

Nov. 13, 2024 — An asteroid struck Mars 11 million years ago and sent pieces of the red planet hurtling through space. One of these chunks of Mars eventually crashed into the Earth and is one of ...

Mars is home to perhaps the greatest mystery of the solar system: the so-called Martian dichotomy, which has baffled scientists since it was discovered in the 1970s.

While cameras have captured meteors streaking across the sky, capturing the sound of a complete meteorite strike on video is extremely rare.

A DRACO ground test would need to capture plume exhaust fully to ensure no radioactive materials are released to the environment, but the U.S. does not possess this type of engine test capability, Ramon Osorio, a spokesperson at NASA’s Marshall Space Flight Center in Huntsville, Alabama, tells Aviation Week.

The wildfires raging around Los Angeles have made plenty of headlines lately, though they are slowly starting to get under control. NASA was a part of that effort, tracking the fire’s evolution via the Airborne Visible/Infrared Imaging Spectrometer-3 (AVIRIS-3) as they raged through southern California.

Groundbreaking research into Mars' energy balance reveals a polar surplus driving dynamic weather patterns, including massive dust storms, offering clues to its climate stability. Scientists at the Un

A Chinese action camera used by NASA, the U.S. Air Force and many Americans is collecting data and communicating with servers in China and Russia, a study said.

Arrokoth is composed of two separate bodies, 3 and 9 miles across. In the distant past they rotated so slowly about each other that their mutual gravitational attraction caused them to come together and merge into a single body. The bi-lobed asteroid looks a lot like a snowman missing a head. Some see a giant peanut.

"it's not completely unusual for asteroids to be near the Earth," Gallagher said. "Our moon is about a quarter million miles away from the Earth. So something 7.6 million miles out would be many, many, many times father away from the Earth than the moon is. No cause for alarm."
