According to a new study, half of the calcium in our Universe comes from supernovae explosions. This means that the material, which consist of our bones and teeth, in fact, is the remains of dead stars that exploded long ago.
“These events are so small that we never know what led to the emergence of such a supernova,” said Wynn Jacobson-Galan, graduate student, North-West and the lead author of a new study published in the Astrophysical Journal this week.
“Watching what happened to supernova in the last month before it reached its stormy end, we looked into previously unexplored place, opening up new possibilities to explore,” added Jacobson-Galan.
An extremely bright event 55 million light years from Earth, has attracted the attention of the international astronomical community in April 2019.
“Every country has a telescope turned to look at the object,” recalls Jacobson-Galan.
Astronomers were so quick that many have observed a supernova in just ten hours after the explosion. “Blast trying to cool down,” — said in a statement Rafaella of Margutti from northwestern University and senior author of the study. “It gives the energy, and the release of calcium is an effective way to do it.”
As it turned out, the explosion was thrown a huge amount of calcium.
Astronomers have caught the event just in time to conclude that this was the greatest amount of calcium, which is ever observed, and ever stood out as a result of one event.
