Astronomers take a photograph of the youngest supernova right after its explosion

Astronomers have obtained a never-before achieved radio astronomical photograph of the youngest supernova. Fourteen days after the explosion of a star in the galaxy Galàxia del Remolí (M51) last June, coordinated telescopes around Europe have taken a photograph of the cosmic explosion in great detail — equivalent to seeing a golf ball on the surface of the moon.

Barely at 23 million light years from Earth, in the constellation of Llebrers, Galàxia El Remolí can be the scene of one of the most violent phenomena in the universe, despite its beautiful appearance: the death of a star in the shape of a supernova explosion. Several combined telescopes spread over Spain, Sweden, Germay and Finland, and the data processing by means of a supercomputer in The Netherlands, enable to have the capacity of a telescope measuring thousands of kilometres. Thus, a really clear image has been obtained, with a detail a hundred times greater than that of the space telescope Hubble. This technique, known as radio interferometry, has allowed Iván Martí and his team to take a photograph of the supernovova SN2011dh just some days after its explosion.
