But suppose we wanted to time an astronomical event--e.g. the time when the 1987 supernova was first detected. For that we need a single agreed-on clock, marking time world-wide, not tied to our locality. That isuniversal time(UT), which can be defined (with some slight imprecision, ...

The Sun does not have enough mass to explode as a supernova. Instead it will exit the main sequence in approximately 5 billion years and start to turn into a red giant. As a red giant, the Sun will grow so large that it will engulf Mercury, Venus, and probably Earth. Even before it...
60Fe in deep-ocean crusts indicates that two supernovae exploded in the solar neighbourhood, reheating the superbubble that harbours our Solar System; calculations of the trajectories and masses of the supernova progenitors gives their explosion times an
The end-of-life scenario for giant stars is different. Stars roughly eight to 40 times more massive than the sun, for example, go through a "red supergiant" phase. Their cores get hot enough to burn carbon, which our sun never will, and they eventually die in powerfulsupernovaexplosions....
Rest. Sorry gang. Sun goes supernova July 22. Some writers merely use the format as a vehicle for humour, as in these examples from Steven Harrison's weekly column from Sydney Australia featuring "a mix of ancient wisdom and modern nonsense": ...

How can you use objects like supernovas and Cepheids to determine distances and other astronomical phenomena? By calibrating their luminosity, we can use their brightness and the inverse square law to determine their distances. Additional resources Watch a video explaining Aristarchus' approach to...
If our sun exploded as a supernova, the resulting shock wave probably wouldn't destroy the whole Earth, butthe side of Earth facing the sun would boil away. Scientists estimate that the planet as a whole would increase in temperature to roughly 15 times hotter than our normal sun's surface...
Arryn Zech stated at Supernova 2018 that as far as she knows, "Sun is meant for Blake".[1] Arryn Zech compared Blake and Sun to Marinette and Adrien from the show Miraculous Ladybug, who form the semi-canonical pairing of Adrienette.[2] In The World of RWBY: The Official Companion ...
