What a great find...we are made of stardust it is true.
Amazing to have a record of it in bacterial form..Maybe one day they will be able to say which supernova it was and when it left the traces in
Heres a good wiki page on the history of supernova observation through history,I found this part interesting:
The supernova explosion that formed the Vela Supernova Remnant most likely occurred 10,000–20,000 years ago.
In 1976, NASA astronomers suggested that inhabitants of the southern hemisphere may have witnessed this explosion and recorded it symbolically.
A year later, archaeologist George Michanowsky recalled some incomprehensible ancient markings in Bolivia that were left by Native Americans.
The carvings showed four small circles flanked by two larger circles. The smaller circles resemble stellar groupings in the constellations Vela and
Carina. One of the larger circles may represent the star Capella. Another circle is located near the position of the supernova remnant, George
Michanowsky suggested this may represent the supernova explosion as witnessed by the indigenous residents.
In 185 CE, Chinese astronomers recorded the appearance of a bright star in the sky, and observed that it took about eight months to fade from the
It was observed to sparkle like a star and did not move across the heavens like a comet. These observations are consistent with the appearance of a
supernova, and this is believed to be the oldest confirmed record of a supernova event by humankind. SN 185 may have also possibly been recorded in
Roman literature, though no records have survived.
The gaseous shell RCW 86 is suspected as being the remnant of this event, and recent X-ray studies show a good match for the expected age.
Interesting stuff indeed,and you are right about the dangers-if a nearby star went supernova,we would be fried to dust.
And chillingly,we would get a certain amount of notice as the wave of gamma/x rays travelled through space towards us...
