Even though Hubble will be replaced in 2021 with the James Webb Space Telescope, the good old telescope proves that it won’t go down without having plenty more to prove. A supernova is one of the most immersive celestial shows in the Universe, as it can be more powerful and bright than an entire galaxy. Capturing such sight in a photo is always welcomed, and the Hubble Space Telescope is still up for such kind of missions.
Even though a supernova means the death of a star, it can also lead to the emergence of many other stars due to the enriching elements sent into space. Supernovae are truly incredible cosmic events, and we now have the privilege to feast our eyes on a portion of another one captured by Hubble.
Blast wave of the Cygnus supernova spotted
Due to the fact that the supernova is located 2,400 light-years away, it cannot possibly pose any threat to our existence. The Hubble telescope operated by NASA and ESA has revealed a new photo for a portion of the imposing cosmic phenomenon:
It may look innocent and delicate, but you would never want to get too close to such a structure. The name of the supernova’s remnant refers to its position in the constellation of Cygnus (The Swan).
An official statement from the Hubble astronomers reveals precious info about the star that caused the supernova remnant:
The original Cygnus supernova explosion blasted apart a dying star about 20 times more massive than our Sun between 10,000 and 20,000 years ago,
Since then, the remnant has expanded 60 light-years from its center.
However, the researchers provide further info about how fast the shockwave expands:
The shockwave marks the outer edge of the supernova remnant and continues to expand at around 350 km per second (217.5 miles per second).
The Hubble Space Telescope will still last somehow through the mid-2020s. Launched 35 years ago, Hubble should continue to work for some space missions through 2025.
