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...

Our new view of the Milky Way

  A lot can change in a year. First came the photo of an orange-and-black ring swirling in a distant galaxy. It splashed across newspapers worldwide last year, announcing the first-ever image of a black hole. Then, early this year, scientists released a data-based picture of our solar system floating at the edge of a towering wave of dazzling molecular clouds and stellar nurseries...

Why astronomy is considered the oldest science

  Millions of years ago, ancient humans living on the African savanna likely gazed up in wonderment at the bright Moon and star-filled sky. This cosmic backdrop wasn't too different from the one we see today; but how they interacted with it almost assuredly was. It wasn’t until humans came to view the stars as tools that we became masters at understanding their movement...

High-energy cosmic rays: Solving a century-old mystery

  “The Earth is being constantly bombarded from space by cosmic rays of an unknown origin!”    This may seem like the cry of a panicking news reporter in a lurid sci-fi tale, but it’s actually a scientific fact — albeit a slightly hyperbolic one.  Mysterious cosmic rays traveling at speeds approaching that of light constantly pelt Earth’s u...
