An international team of scientists found evidence that the rock was launched from Earth by a large impacting asteroid or comet. The impact sent material into space, where it collided with the surface of the Moon 4 bil years ago.
In 60 years of space exploration, we've placed almost 7,000 satellites in orbit. Less than a third still function. The rest is dangerous junk - and their number is growing. Here's how we might mitigate the threat.
The three confirmed planets discovered so far using TESS are all within 100 light-years of our solar system, substantially closer than the nearly 2,700 validated worlds detected using Kepler.
A fresh image from NASA’s New Horizons spacecraft released Tuesday showed the mission’s distant flyby target a billion miles beyond Pluto — nicknamed Ultima Thule — has an elongated shape.
More than 41 years and nearly 18 billion km from Earth, NASA’s Voyager 2 probe has finally passed beyond the protective bubble defined by the Sun’s magnetic fields and solar wind, joining its sistership Voyager 1 in the interstellar space.
It will map and study the tiny world in great detail, eventually returning a piece of Bennu to Earth in 2023. The discoveries of OSIRIS-REx will shed light on our solar system's ancient history.
The Hubble Space Telescope is a hero in the astronomy world - serving 25 years in space. And when it suffered a malfunctioning on October 5th, it took a heroic effort on the part of the Hubble team to get it working again.
NASA's planet-hunting telescope has run out of fuel after a nine-year mission that found more than 2,600 planets orbiting other stars along with thousands of candidate worlds.
Two instruments aboard NASA’s Spitzer Space Telescope – the Infrared Array Camera and the Multiband Imaging Photometer – have captured a spectacular image of the Cat’s Paw Nebula.
It's been a bad couple weeks in space. A week ago, technical difficulties forced engineers to put the Hubble Space Telescope's science mission on hold. Now, the Chandra X-ray Observatory is in safe mode, too.
Technosignatures are signs or signals, which if observed, would allow us to infer the existence of technological life elsewhere in the universe.
A mission to deflect asteroids that might threaten Earth has begun its final assembly phase, according to a news release. NASA is testing a technique meant to protect the planet from an impending asteroid strike.
Using data from NASA's Kepler Space Telescope, an international team has discovered a new exoplanet twice the size of Earth. It orbits its star every six days and is about 10 times closer than Mercury is to the Sun.
Hubble Space telescope snapped a series of stunning images of auroras dancing in the sky. The observations were taken before and after the Saturnian northern summer solstice.
Two years after launch, NASA’s OSIRIS-REx spacecraft has snapped its first pictures of asteroid Bennu, setting the stage for a cautious approach designed to put the probe in orbit around its quarry on New Year’s Eve.
