Team of telescopes finds X-ray engine inside mysterious supernova
ESA's high-energy space telescopes INTEGRAL and XMM-Newton have helped to find a source of powerful X-rays at the centre of an unprecedentedly bright and rapidly evolving stellar explosion that suddenly appeared in the sky earlier this year.
Hubble sees the brightest quasar in the early Universe [heic1902]
The NASA/ESA Hubble Space Telescope has discovered the brightest quasar ever seen in the early Universe. After 20 years of searching, astronomers have identified the ancient quasar with the help of strong gravitational lensing. This unique object provides an insight into the birth of galaxies when the Universe was less than a billion years old.
XMM-Newton captures final cries of star shredded by black hole
Astronomers using ESA's XMM-Newton space observatory have studied a black hole devouring a star and discovered an exceptionally bright and stable signal that allowed them to determine the black hole's spin rate.
Gaia reveals how Sun-like stars turn solid after their demise
Data captured by ESA's galaxy-mapping spacecraft Gaia has revealed for the first time how white dwarfs, the dead remnants of stars like our Sun, turn into solid spheres as the hot gas inside them cools down.
Hubble takes gigantic image of the Triangulum Galaxy [heic1901]
The NASA/ESA Hubble Space Telescope has captured the most detailed image yet of a close neighbour of the Milky Way – the Triangulum Galaxy, a spiral galaxy located at a distance of only three million light-years. This panoramic survey of the third-largest galaxy in our Local Group of galaxies provides a mesmerising view of the 40 billion stars that make up one of the most distant objects visible to the naked eye.
