Did Something Hit Saturn? Astronomers Investigate Possible Impact Flash
Unlike rocky planets where asteroid impacts leave visible craters, gas giants like Saturn have outer layers of hydrogen and helium that can absorb impacts without obvious traces.

Study Reveals Earth's Small Asteroid Likely Originated from the Moon
Asteroid 2024 PT5, discovered near Earth in 2024, is suspected to be a fragment from the Moon’s surface. Researchers found its composition matches lunar rock samples, specifically silicate-rich materials, unlike any known asteroid. Analysis from NASA’s Center for Near Earth Object Studies confirmed it is a natural object, not human-made debris,...

Hera Spacecraft Embarks on Mission to Study Asteroid Redirected by NASA in 2022
The Hera spacecraft has successfully launched from Cape Canaveral, embarking on an international mission to study the asteroid Dimorphos, which was altered in course by NASA’s Double Asteroid Redirection Test (DART) in 2022. Expected to reach its target by December 2026, Hera will examine the impact crater left by the DART mission and deploy two ...

Scientists Reveal It Wasn't Just One Asteroid That Wiped Out Dinosaurs
The massive asteroid that ended the dinosaurs 66 million years ago was not an isolated event, new research has revealed.

Could Earth Have Had Rings Like Saturn? Study Suggests Asteroid Breakup and Cooling Climate
Scientists have proposed that Earth may once have had a ring system similar to Saturn’s, formed by an asteroid breakup 466 million years ago. This ring may have triggered global cooling, contributing to the Hirnantian Ice Age. Evidence includes impact craters near the equator and meteorite debris in sedimentary rocks.

Study Of Craters Suggests Earth Once Had Saturn-Like Rings
The study said that the asteroid belt was formed due to the break-up of an asteroid passing within Earth's Roche limit.

Asteroid Impact Reoriented Jupiter’s Largest Moon Ganymede 4 Billion Years Ago
A colossal asteroid impact about 4 billion years ago dramatically altered Ganymede, Jupiter's largest moon. The asteroid, estimated to be 186 miles wide, struck Ganymede with such force that it reoriented the moon and removed a significant portion of its original surface. This impact not only created a massive crater but also affected Ganymede's in...

Apart From Chicxulub, Another Asteroid Might Have Contributed to Dinosaur Extinction
A mysterious asteroid impact crater have been spotted on the seafloor which is believed to have formed at the same time when dinosaurs were wiped out from the planet. This could mean that not one, but two asteroid impacts were behind the extinction of dinosaurs.

Scientists Discover Undersea Crater Created When Dinosaurs Disappeared
The researchers have named the other crater as Nadir. It is more than 300 metres below the seabed, some 400 km off the coast of Guinea.

Asteroid Bennu's Boulders Act as 'Body Armour' Against Small Meteoroids, Say Researchers
Scientists think that the boulders on the surface of Asteroid Bennu might be acting as a shield against meteoroids. When a meteoroid collides with Bennu, which is a rubber-pile asteroid formed from a much bigger asteroid, it ends up fracturing, chipping, or breaking apart the boulders. Impactors also create smaller craters on Bennu due to the boul...

ESA Shares Photo Of One of The Biggest Impact Basins On Martian Surface
The European Space Agency (ESA) has shared stunning images of one of the biggest impact basins in the Solar System, located on Mars. Hellas, with a diameter of 1,430 miles (2,300km) and a depth of over 4.3 miles (7km), is believed to have formed between 3.8 billion and 4.1 billion years ago after a large asteroid hit the surface of Mars.

World Asteroid Day 2020: Why Is It Observed And All You Need To Know
World Asteroid Day 2020: In December 2016, the UN General Assembly adopted a resolution in order to "observe each year, at the international level, the anniversary of the Tunguska impact over Siberia, on 30 June 1908, and to raise public awareness about the asteroid impact hazard."

Japan Creates First Artificial Crater On Asteroid
Japanese scientists have succeeded in creating what they called the first-ever artificial crater on an asteroid, a step towards shedding light on how the solar system evolved, the country's space agency said Thursday.

Japan Space Agency's Probe Sends Impactor To Blast Asteroid
A Japanese probe on Friday launched an explosive device at an asteroid, aiming to blast a crater in the surface and scoop up material that could shed light on how the solar system evolved.
