An ancient super-Earth offers an unexpected clue that life in our galaxy could be older than scientists thought

Artist's rendition of the hot, rocky planet in TOI-561 - one of the oldest, most metal-poor planetary systems discovered yet in the Milky Way. W. M. Keck Observatory/Adam Makarenko A super-Earth planet 280 light-years away seems to be about 10 billion years old, adding to growing evidence that rocky planets have existed almost as long as our galaxy. Ancient rocky planets offer further evidence that extraterrestrial life may have existed long before humans. Scientists may have better su...

Astronomers spotted a galaxy dying after a major collision. It's bleeding out 10,000 suns' worth of gas each year.

An artist's impression shows galaxy ID2299 losing a tail of gas after being formed in a galactic collision. ESO/M. Kornmesser Astronomers can see a distant galaxy dying as it bleeds cold gas into space. Such gas is critical for forming stars. Galaxies die when they can no longer do so. This galaxy formed from a collision in which two galaxies merged into one. That left a "tail" that's shedding 10,000 suns' worth of gas each year. Visit Business Insider's homepage for more stories.

Warped Starlight Reveals Smallest Rogue Planet Known to Science

Free-floating planets are not bound to any star, having been dumped from their original home systems. New research describes the smallest rogue planet discovered to date, in an astronomical achievement that took an Einstein-inspired technique to new extremes.Read more...

Star with strange chemistry is from out of town

Astronomers have discovered a star in the Milky Way Galaxy with a chemical composition unlike any other star in our Galaxy. This chemical composition has been seen in a small number of stars in dwarf galaxies orbiting the Milky Way. This suggests that the star was part of a dwarf galaxy that merged into the Milky Way.

Our Heartless Milky Way Is Stealing Stars From Other Galaxies

Our thieving Milky Way stole a bunch of stars from unsuspecting galaxies—and it feels no remorse.Read more...

Festive nebulae light up Milky Way Galaxy satellite

The sheer observing power of the NASA/ESA Hubble Space Telescope is rarely better illustrated than in an image such as this. This glowing pink nebula, named NGC 248, is located in the Small Magellanic Cloud, just under 200 000 light-years away and yet can still be seen in great detail.

New family of stars discovered in Milky Way shed new light on galaxy's formation

An astronomer from LJMU's Astrophysics Research Institute has discovered a new family of stars in the core of the Milky Way Galaxy which provides new insights into the early stages of the Galaxy's formation.

Winter Milky Way

The frosty outline of our own home galaxy arcs high overhead on these winter evenings. It stretches across or near some of the brightest stars in the night sky — from Sirius, the brightest of them all, low in the southeast; up past bright orange Betelgeuse above it; by yellow-orange Capella high overhead; and down to Deneb, the tail of the swan, low in the west. That feeble band of light — the Milky Way — represents the combined glow of millions of stars in the disk of the Milky Way galaxy. Yet...

Sculptor

The constellation Sculptor is a bit like a well in the middle of a forest. If you look around you, you see trees. But if you look into the well, all you see is darkness. And that’s the way with Sculptor. If you look at many of the other constellations around us, you see lots of stars. But in Sculptor, there are no bright stars at all. That’s because the constellation is home to the south pole of the Milky Way galaxy. So when you look in that direction, you’re looking away from the star-studded ...

M92

A globular cluster is an impressive sight — a tightly packed ball of hundreds of thousands of stars, held together by their mutual gravitational pull. The finest globular in northern skies is M13, in the constellation Hercules. It’s a favorite target of amateur astronomers. But professional astronomers are just as likely to point their telescopes at another cluster in Hercules. That’s because M92 may well be the oldest star cluster in the entire galaxy. One way astronomers know that is because...

Old Sparklers

Thousands of ancient stars sparkle in the heart of M13, one of the largest star clusters in the Milky Way galaxy. It contains perhaps 500,000 stars packed into a ball that's only a few dozen light-years across. The cluster's stars are all 10 billion years old or older. Under dark skies, M13 is just visible to the unaided eye in the constellation Hercules.

North Poles

The Big Dipper stands high overhead early this evening, with the bowl upside down. As you take in the view, link the two stars at the outer edge of the bowl. If you follow that line down toward the horizon, the first moderately bright star you come to is Polaris. Earth’s north pole aims directly at the star, so it’s also known as the North Star or the Pole Star — it marks true north in the sky. Another north pole stands much higher in the sky at that hour. It’s in Coma Berenices, a faint conste...
