A nuclear explosion ending in fireworks, astronomers witnessed the spectacle

It is located in our immediate suburbs. He, or rather he. Because what the Hubble Space Telescope saw was really a double star. And not just anyone. Undoubtedly the most agitated pair of stars in our Milky Way.

That which AstronomersAstronomers A double star known as R Aquarii is not quite like the others. A so-called symbiotic star because the pair is made up of two very different stars. On the one hand, a red giant is 400 times more massive than our Sun. A bright star that changes dramatically in temperature and shineshine In about a year’s time. At its maximum brightness, it is about 5000 times brighter than our Sun.

Spectacular nuclear explosions

The other star that makes up E Aquarii is a white dwarf. It has made a habit of it, extracting hydrogen from its false twin red giant when it passes as close as it gets. Until the Titanic becomes enough gas to detonate. It appears to us in the form of a veritable cosmic fireworks display. with the The rocketThe rocket Plasma twisted by the force of the blast, channeled by the powerful Magnetic fieldMagnetic field And is expected to reach a distance of 400 billion kilometers at a speed of more than 1.6 million kilometers per hour. It is about 25 times our diameter. solar systemsolar system ! Astronomers believe that such an explosion would have occurred in the late 1970s.

And today, the teamEuropean Space AgencyEuropean Space Agency Those working on images returned by the Hubble Space Telescope take advantage of R Aquarii’s proximity – it’s about 700 A light yearA light year of our land – to offer us a Time lapseTime lapse abnormality of the system. The observations span from 2014 to 2023 and show the star’s dramatic evolution. BinaryBinary And NebulaNebula which surrounds him.
