Giant Ancient Collision May Have ‘Flipped’ the Moon’s Interior, Study Suggests
Scientists analyzing lunar samples from China’s Chang’e-6 mission have uncovered evidence of a colossal ancient asteroid impact. Elevated levels of heavy potassium isotopes suggest extreme heating that drove lighter elements into space, potentially explaining why the Moon’s far side lacks dark volcanic plains seen on the near side.

California Startup Designs Giant Inflatable Bag To Catch Asteroids And Space Debris. How It Works
TransAstra has designed and tested the Capture Bag - an inflatable device available in various sizes, capable of capturing objects ranging from small rocks to boulder-sized asteroids

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.

Asteroid Vesta May Be a Fragment of a Lost Planet, Say Scientists
Vesta, once believed to be a stalled protoplanet, may be a fragment of a long-lost differentiated planet. Using refined gravity data from NASA’s Dawn mission, scientists found it lacks a dense core, suggesting it was ejected during a primordial impact. This revised view may apply to other asteroids and reshape planetary formation theories.

Giant Sun "Umbrella" Tied To Asteroid Might Help Fight Global Warming, Says Scientist
To help combat the effects of global warming, scientists have proposed an innovative idea to shield Earth from the sun with a spaceborne "umbrella" of sorts.

Giant Asteroid To Fly Close To Earth Tomorrow, Has The Potential To Wipe Out A City
Astronomers with the International Asteroid Warning Network are using this close approach to learn as much as possible about 2023 DZ2 in a short time period.

Asteroid Bigger Than the Tallest Building on Earth Just Flew by Safely: Here's How People Are Reacting to It
An asteroid bigger than the tallest building on Earth safely flew by on January 19. The giant rock, named 7482 (1994 PC1), zipped past our planet, nearly 1.93 million kilometres away.

Giant Asteroid To Pass By Earth Today, Says NASA. Here's How You Can Track It
A giant asteroid will whiz past the earth today, NASA has said. The asteroid, called 7482 (1994 PC1), measures more than a kilometre in width (approximately 3,450 feet)

NASA Launches Spacecraft That Will Crash Into Asteroid. Why It's Important
NASA has launched a mission to deliberately smash a spacecraft into an asteroid -- a test run should humanity ever need to stop a giant space rock from wiping out life on Earth.

NASA Launches DART Mission Aboard SpaceX Rocket to Kick an Asteroid Off Course
NASA is preparing a mission to deliberately smash a spacecraft into an asteroid — a test run should humanity ever need to stop a giant space rock from wiping out life on Earth.
