The electricity jostled atoms of gas in the atmosphere, prompting them to emit blue light. A similar scenario would likely play out online in the case of a surprise supernova, with NASA and other science institutions leading the awareness campaign. The most recent nearby supernova appeared long before people could panic about it on Twitter, in , but it could be seen only in very dark parts of the Southern Hemisphere, far from artificial lights.

Other examples are found even deeper in history, in and Betelgeuse would provide a far better show; the other stars were thousands of light-years from Earth, rather than hundreds.

When stars explode, they release a cascade of newly forged elements into space. These elements glide across the universe inside particles of dust, settling on whatever they encounter. It is also visual to everyone except at latitudes south of 82 degrees between mid-September to mid-March, with the best observations in mid-December.

The Brightest Stars in the constellation Orion. Betelgeuse is considered a red supergiant based on the size and temperature and appears orange-red in color because of its low temperature. In late , it was reported that the brightness of Betelgeuse had decreased significantly and that it may be approaching supernova. But we need to be judicious while moderating your comments.
