Earth's oldest meteorite crater discovered in Australian outback

Researchers say the 3.47-billion-year-old meteorite impact crater could help explain how life on Earth began.

Violence can leave genetic marks on future generations

In 1982, the Syrian government besieged the city of Hama, killing tens of thousands of its own citizens in sectarian violence.The grandchildren of women who were pregnant during the siege still bear marks of it in their genomes.

Sunken Continents Near Earth's Core Could Unbalance Our Magnetic Field

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field.

Radio Telescopes Are Revealing a Trove of Faint Circular Objects in The Sky

Radio astronomers see what the naked eye can't. As we study the sky with telescopes that record radio signals rather than light, we end up seeing a lot of circles.

Melting Antarctic ice will slow the world's strongest ocean current

Part of the system that pumps water, heat and nutrients around the globe is at risk. Climate change could slow the Antarctic Circumpolar Current down 20% by 2050.

Water May Have Come Into Existence Far Earlier Than We Ever Realized

Life's most vital elixir may have formed within 200 million years of the Big Bang, new research suggests.

Centre of the Earth could hold large reservoir of iron-helium compounds

In the new work, Hirose and colleagues at other institutions in Japan and Taiwan propose that the iron core of the Earth formed bonds with helium, allowing the core to act as a reservoir. 

This Robot Swarm Can Flow Like Liquid and Support a Humans 'Weight

These robots can flow around obstacles before hardening into weight-bearing tools that push, throw, twist objects like a wrench—and bear up to 150 pounds of weight.

The International Space Station is overly sterile

Astronauts often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space. These issues could be due to the excessively sterile nature of spacecraft. 

Star mergers produce universe's highest-energy particles

Ultrahigh Energy Cosmic Rays are the highest-energy particles in the universe, whose energies are more than a million times what can be achieved by humans.

Melting Antarctic ice sheets are slowing Earth's strongest ocean current

This melting has implications for global climate indicators, including sea level rise, ocean warming and viability of marine ecosystems.

NASA's Hubble provides bird's-eye view of Andromeda galaxy's ecosystem

Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon. 

Speedy white dwarf planets are more likely to be habitable

Speedy’ planets orbiting faster in smaller orbits around white dwarfs are warmer than expected and more likely to maintain habitable conditions than the planets around the sun-like stars.

Lucy Captures Its First Images of Main-Belt Asteroid Donaldjohanson

NASA's Lucy spacecraft will fly by the small asteroid Donaldjohanson on April 20, 2025.

Study Reveals How Earth's Orbit Triggers Ice Ages

New research has demonstrated the precise relationship between past ice ages and each wobble, tilt, and angle of the planet's path, unlocking a new tool for predicting the future fluctuations of our global climate.
