Star formation underway 250 million years after Big Bang

Astronomers have observed a galaxy 13.3 billion light years away that includes stars that must have been shining just 250 million years after the Big Bang.

NASA just announced new evidence for water plumes on Europa

Citing data collected by NASA's Galileo probe more than two decades ago, scientists report that giant jets of water are spouting more than 100 miles off Jupiter moon Eupora's surface.

Mars Helicopter to Fly on NASA’s Next Red Planet Rover Mission

The Mars Helicopter, a small, autonomous rotorcraft, will travel with the agency’s Mars 2020 rover mission, scheduled to launch in July 2020, to demonstrate the viability and potential of heavier-than-air vehicles on Mars.

‘Monster’ black hole consumes the Sun’s mass every two days

Australian astronomers have fond what may be the fastest-growing black hole in the known universe, an ancient 20-billion-solar mass beast consuming the mass of the Sun every two days.

Upgraded SpaceX Falcon 9 rocket launched

SpaceX successfully launched its first "block 5" Falcon 9 rocket, carrying a satellite for Bangladesh. Then the rocket's first stage made a safe landing on an offshore droneship -- the 25th such recovery for SpaceX so far.

UK astronomers find exoplanets with sodium, helium in atmospheres

A team of researchers, using Europe’s Very Large Telescope in Chile, has found an exoplanet, WASP-96b, with a cloud-free atmosphere, allowing them to detect sodium in levels similar to abundances on Earth.

Stellar mass black holes swarm in Milky Way’s core

The Chandra Observatory has found direct evidence for up to 10 stellar-mass black holes and thousands more lurking within a few light years of Sagittarius A*, the supermassive black hole at the center of the Milky Way.

Jupiter and Venus Change Earth's Orbit Every 405,000 Years

A new study presents the first physical evidence that the Venus’ and Jupiter’s gravity can cause shifts in Earth’s orbit—and swings in its climate—every 405,000 years.

Massive sinkhole opens up in New Zealand

One scientist and several nearby dairy farmers said that the sinkhole was the largest they had ever seen, and the earth at the bottom dates back to the paleolithic era dating 60,000 years ago.

NASA's InSight Lander Is On Its Way to Mars

NASA’s robotic lander InSight officially started its journey to Mars following a successful predawn launch aboard an Atlas V rocket Saturday morning. The launch took place at 4:05am local time from California.

Scientists detected helium in an exoplanet's atmosphere for the first time

WASP-107, the star around which WASP-107b orbits every six days, is so powerful that it is gradually dissolving the exoplanet’s atmosphere. As a result, WASP-107b leaves a comet-like trail of helium in its wake.

Stephen Hawking's final theory about the big bang

The theory, which was submitted for publication before Hawking's death earlier this year, is based on string theory and predicts the universe is finite and far simpler than many current theories about the big bang say.

A Hidden Galaxy Has Been Found Orbiting Our Milky Way

Scientists have found what looks like an exceedingly small galaxy in orbit around our Milky Way. Named Hydrus 1, it’s located about 90,000 light-years from Earth, between the Small and Large Magellanic Clouds.
