seen by southwestern American Indians, as suggested by certain rock paintings discovered in Arizona andNew Mexico. It was bright enough to be seen during the day, and its great luminosity lasted for weeks. Other prominent supernovae are known to have been observed fromEarthin 185, 393, 1006,...
Astronomers have spotted the most powerful cosmic explosion ever seen — a mysterious, years-long eruption 10 times brighter than any observed supernova.Astronomers spotted the event, named AT2021lwx, 8 billion light-years from Earth. Releasing rough... ...
Astronomers have never seen a gamma-ray burst in our galactic neighborhood (meaning the local galaxies around us). That's because stellar explosions themselves aren't too common. A star in our Milky Way galaxy will go supernova around once a century. But a huge star, the type that's ...
SN2016aps also lacks the [O III] emission seen at 5000Å (see also Supplementary Information). The apparent absorption in PS16dtm at 7000Å is a telluric feature from the Earth’s atmosphere. Supplementary information Supplementary Information Supplementary discussion. Rights and permissions ...
It was so powerful that it affected Earth’s atmosphere, a remarkable feat for something more than two billion light-years away. It’s the brightest GRB ever observed, and since then, astrophysicists have searched for its source. Continue reading“The Brightest Gamma Ray Burst Ever Seen Came ...
some 700 others have been observed since. In 1987 Supernova 1987A appeared in the Large Magellanic Cloud. It was the first supernova visible to the unaided eye since 1604, and its eruption marked the first time that neutrinos were detected on earth from such an event (seeneutrino astronomy)...
Fermi-LAT detection of G118.4+37.0: a supernova remnant in the Galactic halo seen around the Calvera pulsar The discovery of a non-thermal radio ring of low surface brightness about one degree in diameter has been recently reported around the location in the sky ... M Araya - 《Monthly No...
supernova had settled into the expected color palette, suggesting that the explosion had finally destroyed the dust shell. This rapid change from red to the normal blue of a very hot shockwave, within the first few hours after the exp...
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...
This image shows the process of going from the raw data captured by a telescope to a stunning astronomical image like the one featured here, showing the Vela supernova remnant as seen with the VLT Survey Telescope (VST). You might wonder how you get from a 268-megapixel sensor to a 5...
