Astronomers confirm a 2nd Trojan asteroid for Earth

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.

A Tracking System is now Scanning the Sky Every 24 Hours

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.

New "Test-bed" telescope joins hunt for threatening asteroids

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.

Earth Is Safe From Asteroid Apophis for 100 Years

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. 

New superhighway system discovered in the Solar System

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.

Hayabusa-2: Capsule with asteroid samples in 'perfect' shape

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.

OSIRIS-REx captures samples from asteroid Bennu

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.

Ganymede shows hints of Solar System's largest impact

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.

Earth's oldest asteroid strike linked to 'big thaw'

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. 

In death of dinosaurs, it was all about the asteroid

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.

Earth's Oldest Rock Found on the Moon

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.

NASA mission OSIRIS-REx has arrived at near-Earth asteroid Bennu

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.

Japan lands rovers on asteroid in historic mission

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.

Mission to Slam Spacecraft Into Asteroid Has Begun Construction

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.

First interstellar immigrant discovered in the solar system

The asteroid, currently nestling in Jupiter's orbit, is the first known asteroid to have been captured from another star system.
