Every second in the universe meets spectacular events, some of which manage to create outstanding images. That’s the case for an event which took place on Thursday, when NASA’s Hubble Telescope captured some beautiful shots of Veil Nebula Supernova.
A Supernova is known to be the biggest explosion in the outer space, being extremely luminous. Typically, a Supernova appears once in 50 years in our galaxy. Also, a star’s explosion takes places each and every second and some of them are not that far from our planet.
The beautiful images were combined by the researchers into several videos, displaying a gathering of a multicolored material having 110 light-years wide and can be found in Cygnus constellation, at a distance of 2,100 light years from our planet.
With respect to the origins of this Supernova, it was created for about 8,000 years ago, after a star much bigger than the Sun exploded, emitting a bright light which could have been seen by the people living in those times.
Members of the ESA explain that many astronomers have already come up with theories as to the Veil Nebula’s birth. They believe that, before the source star of this nebula exploded, strong stellar winds began being expelled. Consequently, a large cavity appeared in the surrounding interstellar gas.
The picture as a whole is made up of 6 other images. Each color represents a different element. Red is hydrogen, blue is oxygen, green is sulfur.
NASA made a 3D video to see how the Supernova works, revealing its sparse and irregular structure.
Veil Nebula was also captured by Hubble Telescope in 1997, so the newly photographed pieces help astronomers see how the cloud evolved and expanded in the last 18 years. In 1997, the photographs were taken by Hubble’s Wide Field and Planetary Camera 2, while the recent once were taken by Wide Field Camera 3, installed by astronauts in 2009.
The Hubble Telescope started its activity in 1990. Its first images were blurry and soon the scientists discovered that it has a cracked mirror. When the problem was solved, Hubble began to capture amazing images.
