   13 Jun 01:00:01   |  Universe Today

Saturn’s moon Mimas is the smallest of the gas giant’s major moons. (Saturn has 62 moons, but some of them are tiny moonlets less than 1 km in diameter.) Two new studies show how Mimas acted as a kind of snow-plow, widening the Cassini division between Saturn’s rings. Saturn’s iconic rings set it apart from …

It?s Been Exactly One Year Since Opportunity Sent This Final Message Home ? on its 5,111th Martian Day

   12 Jun 01:00:01   |  Universe Today

Opportunity’s final message home is not much to look at on its own. If you’re old enough to remember film cameras, it looks like the final exposure on a roll of film, developed but partly missing. It’s a suitable epitaph for Opportunity’s mission. Opportunity captured this image with the left half of its PanCam, or …

Alpha Centauri is the closest star system to us, at 4.37 light-years (about 25 trillion miles) away. In 2016, astronomers discovered an exoplanet orbiting one of the three stars in the Alpha Centauri system. Spurred on by that discovery, the European Southern Observatory (ESO) has developed a new instrument to find any other planets that …

Perfect Example of a Barred Spiral Galaxy, Seen Face On. This is What Our Milky Way Might Look Like

   11 Jun 01:00:01   |  Universe Today

The Hubble Space Telescope has given us a beautiful image of the barred spiral galaxy NGC 7773. This is a classic galaxy of this type, and highlights the bright bar of concentrated stars that anchors the galaxy’s stately spiral arms. It was captured with the Hubble’s workhorse Wide Field Camera 3 (WFC3.) NGC 7773 is …

   10 Jun 01:00:01   |  Universe Today

370 light years away from us, a solar system is making baby planets. The star at the center of it all is young, only about 6 million years old. And its babies are two enormous planets, likely both gas giants, nursing on gaseous matter from the star’s circumsolar disk. The host star in this system …

   09 Jun 01:00:01   |  Universe Today

Whenever scientists announce an upcoming close encounter with an asteroid, certain corners of the internet light up like the synaptic rush that accompanies a meth binge, with panicky headlines shouted straight from the brain stem. But never mind that. We’re not that corner of the internet. We’re sober, yo! The fact of the matter is, …
