Supernovas, when they occur in our galaxy, are so bright that they can be seen in the sky, even in the middle of the day. They don’t happen that often, however. Centuries or millennia can pass between a supernova which can be visible with the naked eye on Earth. Astronomers have ...
In our Galaxy the expected rate of supernovae is about one in every fifty years or so, although it is only the relatively nearby ones that are expected to be visible optically, due to obscuration. Over the last two thousand years or so there are historical records of nine Galactic super...
No supernova has been spotted in our Galaxy for the past 300 years. Since the explosion of a visible supernova is a chance event, there is no way to say when the next one might occur. Around the world, dozens of professional and amateur astronomers keep a sharp lookout for “new” sta...
Statistically speaking, a supernova in our own galaxy has been a long time coming. Supernovae occur in our galaxy at a rate of about one or two per century. Yet we haven’t seen a supernova in theMilky Wayin around 400 years. The most recent nearby supernova was observed in 1987, ...
Here we report UV spectra of the nearby SN 2023ixf in the galaxy Messier 101 (M101). Using the UV data as well as a comprehensive set of further multiwavelength observations, we temporally resolve the emergence of the explosion shock from a thick medium heated by the SN emission. We ...
Supernova Oh Over We could leave today And throw our cares away And dance until the night And dream throughout the day you and me My supernova dream My love My Love Oh We could leave today And throw our cares away And dance into the night And dream throughout the day You and me Oh...
As an example, Cabrales suggested that 32 star systems should already have seen the bright afterglow of SN 1987A, a supernova in our own Milky Way galaxy that lit up Earth’s skies in (you guessed it) 1987. If there’s anyone manning radio telescopes and transmitters on a planet around...
See the stunning Rosette Nebula in all its glorious colors How to see the stunning Perseid meteor shower this weekend Stunning images of Jupiter’s moon Europa show it has a floating icy shell Stunning image shows the magnetic fields of our galaxy’s supermassive black hole...
In 2021, amateur astronomer Dana Patchick tracked SN 1181 back to its location in the nebula Pa 30 that's situated within the Milky Way, determining the supernova erupted around 1,000 years ago (about 200 years before our ancestors spotted and documented it). An illustration shows a white...
Supernova 1991F appeared in the lenticular galaxy NGC 3458 (UGC 6037). On discovery, it was classified as type I, although no subtype (i.e., Ia or Ib/c) was assigned to it. In this paper, we present several low resolution spectra of this supernova. One of them was recorded ten da...
