For the first time, a team of Israeli scientists managed to collect data on this cosmic phenomenon. The results of this pioneering research were recently published in the prestigious journal Nature.

About 20 million years ago, A Estrella Monumental Proportions reached the end of its life cycle in a spectacular way: Explodes in a supernova. This event in a nearby galaxy triggered Diffusion of elements essential to life everywhere.
A year ago, by a happy coincidence, the light emitted by this explosion finally reached the planet. TierraAllows a group of scientists from Israel Watch and register for the first time Initial stages of one Supernova.

The view constructed from this data provides a comprehensive overview of the birth of some of the most essential elements around the universe. FootballThe same one that strengthens teeth, and HierroAn essential mineral for the production of red blood cells.
Avishai Kal-yamAstrophysicist Weizmann Institute of ScienceRevealed: “We are actually looking at the cosmic furnace where the heavier elements are formed, as they form. We're watching it as it happens.. “This is truly a unique opportunity.”

In search of early detection of supernovae
The results of this pioneering research were recently published in a prestigious journal Nature magazineThere they announced a possible creation black hole After the explosion of a nearby giant star Galaxy Messier 101.

The discovery began with the observation of an amateur astronomer who discovered it Changes in the galaxy and alerted investigators to the developing phenomenon. Soon, the team turned their telescopes toward the star and began meticulously documenting the first. Eruption levels.
Cooperation with National Astronomy and Space Administration (NASA) Important because this space agency made its programming a target Hubble Space Telescope Towards a supernova allows us to observe the ultraviolet light emitted in the early stages of the explosion, an event normally hidden behind Earth's atmosphere.
Data collected with detection of elements such as Carbon, Nitrogen Y Oxygen Injected into space, it revealed a significant difference in the star's initial mass and the mass ejected during the explosion.

“We suspect that there was a black hole left after the explosion, a newly created black hole that wasn't there before. It is a remnant of the explosion. “A little bit of the star's mass collapsed toward the center,” Gal-Yam explained.
This exhaustive study found the supernova's fingerprint From its birth to its endThese could not only expand our understanding of cosmic phenomena, but also help scientists predict them Future supernovae In other corners of the universe.
“We suspect that in the next few years, not for all stars, but for some of them, this star we believe will explode.”Gale-Yam pointed out the relevance of this discovery for the study and prediction of puzzling astronomical phenomena.
