What’s Happening with Betelgeuse? Astronomers Propose a Specialized Telescope to Watch the Star Every Night20 Oct 2020, 10:26 UTC Starting in late 2019, Betelgeuse began drawing a lot of attention after it mysteriously started dimming, only to brighten again a few months later. For a variable star like Betelgeuse, periodic dimming and brightening are normal, but the extent of its fluctuation led to all sorts of theories as to what might be causing it.

Universe Today 16 Oct 2020, 19:44 UTC There are instances other than pandemics when it is necessary to work remotely. Spacecraft operators are forced to do most of their work remotely while their charges travel throughout the solar system. Sometimes those travels take place a little closer to home. Engineers at DLR, Germany’s space agency, recently got to take the concept of remote working to a whole new level when they operated a rover in a whole different country almost 700 kilometers away while working remotely from their primary office.

Image via NASA/ Johns Hopkins APL/ SWRI/ Thomas Pesquet/ ESA/ EurekAlert!.With their tall peaks reaching into the sky and and their snow glistening in the sun, snowcapped mountains on Earth are beautiful. Other planets, like Mars and Venus and even some moons, also have mountains, but they lack the scenic snow cover of earthly mountains. One notable exception, though, was discovered in 2015 by the New Horizons spacecraft, when it made its sweep through the outer reaches of our solar system. I’m talking about the snowcapped mountains of Pluto!Not only does Pluto have mountains, which was a bit surprising given its small size, but Pluto’s mountains also have snow on their peaks. There is one significant difference, though, between the mountains of Earth and Pluto. The “snow” or frost on Pluto consists of frozen methane (CH4) instead of water ice crystals. Meanwhile, Pluto’s mountains themselves are composed of rock-hard water ice.The new research, by an international team of scientists led by researchers from Centre National de la Recherche Scientifique (CNRS) in France, was announced on October 13, 2020.The associated peer-reviewed paper was published in ...
