Astronomers already knew Earth had one Trojan. Now we know it has two, with the second announced on February 1, 2022. This new Earth Trojan has been labeled 2020 XL5.
There was a huge weakness in our asteroid defense system when only one of the hemispheres was covered by telescopes that constantly scan the sky. Now NASA funded two more telescopes in the southern hemisphere.
Working alongside its northern-hemisphere partner telescope, the ESAs Test-Bed Telescope 2 (TBT2) at La Silla Observatory in Chile will keep a close eye on the sky for asteroids that could pose a risk to Earth.
Asteroid 99942 Apophis had been identified as one of the most hazardous asteroids. The near-Earth object was thought to pose a slight risk of impacting Earth in 2068, but now radar observations have ruled that out.
Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. They could be used to send spacecraft to the far reaches of our planetary system.
The container with material from a space rock called Ryugu parachuted down near Woomera in South Australia on Saturday evening. The samples were originally collected by the Japanese spacecraft Hayabusa-2.
NASA's asteroid sampling aircraft OSIRIS-REx, which touched asteroid Bennu last week, has collected such abundant quantity of asteroid particles that it is jammed open and these particles are leaking slowly in the space.
Researchers have found what may be remnants of the solar system’s largest impact structure, ancient concentric troughs that extend across almost the entire surface of Jupiter’s moon Ganymede.
Scientists have discovered Earth's oldest asteroid strike occurred at Yarrabubba, in outback Western Australia 2,2 billion years ago, and coincided with the end of a global deep freeze known as a Snowball Earth.
Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international team of researchers. It was all about the asteroid.
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.
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.
Japanese scientists have praised "the world’s first rover to land on the surface of an asteroid." The Hayabusa2 is expected to land a German-made lander carrying a larger rover in October.
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.
The asteroid, currently nestling in Jupiter's orbit, is the first known asteroid to have been captured from another star system.
