The red supergiant Betelgeuse is one of the brightest stars in the night sky and appears even more luminous because it is so close to Earth, only 650 light-years away. But the star also periodically changes in brightness, which was first noted in the 1830s by the British astronomer John Herschel. Betelgeuse experienced an unexpected dimming during December 2019 and the first quarter of 2020, reaching an historic minimum on February 7-13. This dimming has mystified astronomers, who scrambled to develop several theories for the abrupt change. Ultraviolet observations by the NASA/ESA Hubble Space Telescope suggest that the dimming was probably caused by an immense amount of superhot material ejected into space. The material cooled and formed a dust cloud that blocked the starlight coming from about a quarter of Betelgeuse’s surface.
If ever there might be a suitable world that Marvel’s Jade Giant might want to settle down on, it’s this spooky, green-tinted rendering of Mars’ nightside atmosphere delivered by the enterprising folks at NASA.
The Pentagon is expected to unveil a task force dedicated to investigating reports of unidentified flying objects (UFOs) from service members led by top officials in the coming days.
Astronomers looking at the core of the Milky Way have discovered some of the most extreme stars in our galaxy. Orbiting the central supermassive black hole known as Sagittarius A*, one of these stars is now the fastest ever discovered in the galaxy, moving at around 8 percent of the speed of light.
To breathe or not to breathe, that is the question.
The end of the universe as we know it will not come with a bang. Most stars will very, very slowly fizzle as their temperatures fade to zero.
A nighttime drive on a mountain path half a century ago led to a legend that forever changed this community and could now be instrumental in its survival.
