Illustration of the Milky Way seen from Earth where supernova accelerates cosmic rays to high energies. Some of these cosmic ray particles enter the Earth’s atmosphere, where they produce shower structures of secondary particles. A surprising result is that changes in cosmic rays throughout Earth...
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 54...
The warping also produced multiple images of the explosion over different time periods that all arrived at Earth at the same time and were caught in one Hubble image. That was possible only because the magnified images took different routes through the cluster due both to diffe...
While astronomers have seen many supernovae over the years, it's relatively rare to catch one in the process of happening. It's even rarer to watch it throughout the days leading up to the explosion. For this supernova, named SN 2020tlf, the ...
According to archaeologists, an enigmatic stone found the Himalayan territory of Kashmir may represent the oldest depiction ever found on Earth of a supernova. Seen here is a copy of the stone carving superimposed on a sky map of HB9’s region.The newly published study on the drawing propos...
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 ...
Here, material near the reverse shock is seen in different ionisation stages, at the shock in X rays, and further inside in optical lines from highly-ionised Fe [236]. Such studies provide better detail about how atomic-line excitations depend on the kinematics of the ionising reverse shock,...
In 1987 a star exploded in the Large Magellanic Cloud and, even thought it was still 168,000 light years from Earth it afforded astronomers a great opportunity to study a supernova up close, closer than ever before. At the heart of the slowly expanding supernova remnant is a ...
11, 2021, was in a galaxy only 1 billion light-years from Earth, meaning the light traveled for a billion years through space before reaching the telescopes' sensors. That may seem extremely far, but most have come from between 6 and 13 billion light-years away, from the time of the ...
The supernova SN 1987A occurred 160,000 light-years from Earth in the Large Magellanic Cloud. It was first observed on Earth in February 1987, and its brightness peaked in May of that year. It was the first supernova that could be seen with the naked eye since Kepler’s Supernova was...
