Hubble finds hints the Sombrero galaxy had a turbulent past

New data from the Hubble Space Telescope reveals the popular Sombrero galaxy may have had a more violent past than previously thought. Based on the number of metal-rich stars Hubble spotted in the galaxy’s extended halo, astronomers think the seemingly serene Sombrero galaxy could have once went through a major merger with another galaxy.“The Sombrero has always been a bit of...

Hubble captures a smeared fingerprint of an "anemic" galaxy

Looking at this face-on view of the galaxy NGC 4689, as seen by the Hubble Space Telescope, you can barely tell it's a spiral galaxy. Instead, thanks to its relatively dim spiral arms, NGC 4689 looks more like a smeared cosmic fingerprint — especially when compared to some of Hubble's other high-contrast hits.This mottled appearance is because NGC 4689 is an “anemic...

The hottest known exoplanet is melting molecules in its atmosphere

The hottest known exoplanet is back in the news, answering some questions about ultra-hot planets, while also raising some new ones. The planet, KELT-9b, was first announced in 2017. It’s roughly three times the mass of Jupiter, orbits its star every day and a half, and is a whopping 7,800 degrees Fahrenheit (4,300 Celsius). Just for the record, that’s hotter than some...

Astronomers target the celestial hourglass of a dying star

Beauty can come after death — well, at least after the death of a star. The image captured above, taken by the Gemini Observatory, showcases the planetary nebula known as CVMP 1, which is the outcome of a main-sequence star that blew off its outer layers as it ballooned into a red giant. This cosmic wonder doesn't have a long lifespan, though. Its hourglass shape will onl...

When Betelgeuse goes supernova, what will it look like from Earth?

A plume of gas nearly the size of our solar system erupts from Betelgeuse's surface in this artist's illustration of real observations gathered by astronomers using the Very Large Telescope in Chile. If you stargaze on a clear winter night, it’s hard to miss the constellation Orion the Hunter, with his shield in one arm and the other arm stretched high to the heavens. A...

How many planets are there in the universe?

Astronomers estimate that there is roughly one exoplanet per star in our galaxy. Of course, some stars have many planets – our own Sun has eight. And some stars have none. But if a star lives long enough, forming planets seems to be the rule, rather than the exception.That doesn’t mean astronomers can map all of those billions of stars though. When it comes to exopl...
