'Remarkable' explosions from colliding, dead stars could reveal the true expansion rate of the universe

The collision and merger of two stellar corpses called neutron stars could help scientists unravel a long-standing mystery surrounding the expansion rate of the universe. Since the early 1900s, scientists have known that the universe is expanding. The discovery was made thanks to astronomer Edwin Hubble’s observation that the more distant galaxies are from each…

NASA astronaut walks on the 'moon' to get ready for Artemis landings (photos)

Chandrayaan-3’s measurements of sulfur open the doors for lunar science and exploration

In an exciting milestone for lunar scientists around the globe, India’s Chandrayaan-3 lander touched down 375 miles (600 km) from the south pole of the Moon on Aug. 23, 2023. In just under 14 Earth days, Chandrayaan-3 provided scientists with valuable new data and further inspiration to explore the moon. And the Indian Space Research Organization has shared these initial results with the world. While the data…

Could AI find alien life faster than humans, and would it tell us?

World Space Week 2023 is here and Space.com is looking at the current state of artificial intelligence (AI) and its impact on astronomy and space exploration as the space age celebrates its 66th anniversary. Here, Keith Cooper discusses how AI might help humans detect alien life. Turn a radio telescope to the stars in the…

Satellite time-lapse shows 45-mile long iceberg colliding with Clarence Island in Antarctica

A massive iceberg around half the size of Rhode Island recently smashed into a penguin refuge in Antarctica, two years after it was birthed from a similar collision. But it seems to have caused minimal damage. The hefty tabular berg, named D-30A, is around 45 miles (72 kilometers) long and 12.5 miles (20 km) wide.…

Severe space weather is messing up bird migrations, new study suggests

New research indicates that severe space weather events, such as solar flares, disrupt birds’ navigational skills during long migrations. Previous research has indicated that when flying at night, birds (and many other animals) use Earth’s magnetic field for navigation. Because solar events disrupt the magnetic field — as well as produce auroras — birds have more difficulty…

What are kilonovas?

A kilonova is a bright blast of electromagnetic radiation that happens when two neutron stars or a neutron star and a stellar-mass black hole collide and merge.  When these collisions occur, a vast amount of material is ejected from the neutron stars, the ultradense cores of massive stars that have reached the ends of their…

Euclid 'dark universe' telescope is back on track after finding its guiding stars

The European Space Agency’s (ESA) dark universe detective, the Euclid spacecraft, is on track after locating its guiding stars, which it lost as a result of cosmic misidentification.  The satellite can now begin investigating dark matter and dark energy, which are some of the greatest mysteries in cosmology. Dark matter  accounts for 85% of the…
