Hubble Views an Exploding Supernova (Video)

The Hubble Space Telescope, which has been operating in space for more than 30 years, has been able to observe a supernova that exploded 70 million light-years away using time-lapse photography. The observations made are of great importance in calculating the intergalactic distance.

Transported to orbit around Earth by the Discovery space shuttle in April 1990. Hubble Space TelescopeDuring his 30 years in space, he produced many impressive photographs. Now Hubble has overshadowed all the stars in his galaxy and 5 billion suns Managed to record a time lapse footage of a bright supernova revealing.

Observing the exploding star for a year, Hubble watched the explosion shrink and managed to shoot time-lapse shots that could be considered quite rare for supernovae. SN2018gv The supernova, known as the supernova, was first released from Earth in mid-January 2018. 70 million light years barred spiral celestial island located away NGC Of 2525 had been seen on the edge. Researchers Type Ia He says he has a supernova.

Supernova explosion observed by Hubble:

In the few seconds video above, with the Hubble Space Telescope February 2018 – February 2019 There are 1-year observations recorded between dates. These captured images are of great importance to the scientific world because the researchers used the brightness observed from Earth during Type Ia explosions the distance between galaxies they can calculate.

At this point, scientists compare the theoretical distance with the observed brightness to the supernova and the galaxy it is in. the distance They state that it is possible to calculate correctly. This shows scientists how fast the universe is expanding at different distances from a given point in space. (Hubble constant) offers more data to calculate. It can be said that this is one of the most important reasons for Hubble’s observation of the supernova.

When seen at the very beginning of the video, the supernova brighter than all other stars It was glowing somehow, but the intensity of the explosion rapidly decreased as the fuel ran out. NASA in a blog post on this topic “When a star releases in a few days as much energy as our Sun does in a few billion years, you know it won’t stay visible for long.” he wrote.
