We may have spotted a planet orbiting three stars for the first time - CNET

This composite image of GW Orionis comes from the European Southern Observatory's Very Large Telescope in Chile.

But new analysis of the protoplanetary cloud suggests that process may have already yielded some pretty big cosmic fruit.

Researchers led by Jeremy Smallwood, a recent Ph.D. graduate in astronomy from the University of Nevada, Las Vegas, noticed a significant and befuddling gap in the dusty discs, which are not only broken up but also warped.

Mysterious World Appears to Be The First Exoplanet Ever Found Orbiting 3 Stars

Our Solar System, with just one star in the sky, may be a bit of an oddball. Most of the stars in the Milky Way galaxy actually have at least one gravitationally bound stellar companion, meaning that two-starred worlds like Tatooine are probably not uncommon.

Star systems, however, are not confined to a maximum of two stars. We've found systems of up to seven stars bound together in a complex orbital dance.

UNLV grad's team may have found first planet orbiting 3 stars | Las Vegas Review-Journal

“Star Wars” showed us a planet with two suns in the sky. Now a UNLV researcher and an international team are doing one better: They may have identified the first planet orbiting around three stars.

In a star system 1,300 light years away in the constellation of Orion, Jeremy Smallwood and other researchers believe they’ve detected a planet — not because of what they can see with a high-powered telescope, but what they can’t.

Energy burst from most distant known galaxy might have been a satellite orbiting Earth

Recently, astronomers thought they had seen evidence for one of these explosions from the most distant galaxy every seen. But a recently published paper casts doubt on these claims, suggesting it might have been caused by a more mundane source much closer to home.

No gamma ray bursts have been documented in our galaxy yet, which may not be a bad thing. A gamma ray burst pointed directly at the Earth would probably lead to a mass extinction event, and the end of civilisation as we know it.

New UAE space mission will orbit Venus and land on an asteroid - KAKE

The United Arab Emirates is setting a course for Venus and the main asteroid belt. The new interplanetary mission, announced by the UAE Space Agency on Tuesday, will launch in 2028.

The spacecraft will go on a five-year expedition, orbiting Venus and Earth before reaching the main asteroid belt located between Mars and Jupiter in 2030. There, it will observe seven asteroids before landing on an asteroid that is 347 million miles (560 million kilometers) from Earth in 2033.

A NASA spacecraft orbiting Mars snapped a photo of the Perseverance rover in the crater below

In a recent satellite photograph, NASA’s Perseverance rover can be spotted rolling along Mars’ Jezero Crater in search of the next ancient boulder.

Earlier this year, the spacecraft captured the Curiosity rover trekking up Mont Mercou, which is part of a hilly region at the base of Mount Sharp – an area observed only from a distance since the rover landed nearby in 2012.

Watching Earth-Orbiting Satellites, by Dennis Mammana | Creators Syndicate

From time to time, my father would step into the backyard for an evening smoke, and I would often accompany him to gaze into the starry heavens and wonder.

It was on one of those nights in August of 1960 that my dad told me we would see a satellite named Echo that was carrying President Eisenhower's voice. As a 9-year-old boy, I imagined watching the satellite pass overhead while hearing Ike's voice booming from the heavens.
