Death by Spaghettification: Telescopes Record Last Moments of Star Devoured by a Black Hole!

October 16, 2020October 16, 2020 Ektoras PouliasisArticle

A rare blast of light, emitted by a star as it is sucked in by a supermassive black hole, has been spotted by scientists using telescopes from around the world. The phenomenon, known as a tidal disruption event, is the Read More …

The black hole always chirps twice: Scientists find clues to decipher the shape of black holes!

October 10, 2020October 10, 2020 Ektoras PouliasisArticle

A team of gravitational wave researchers led by the ARC Center of Excellence for Gravitational Wave Discovery (OzGrav) report that when two black holes collide and merge, the remnant black hole “chirps” not once, but multiple times, emitting gravitational waves—intense Read More …

Three scientists share Nobel prize in physics for work on black holes!

October 6, 2020 Ektoras PouliasisArticle

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2020 with one half to Roger Penrose, University of Oxford, UK, “for the discovery that black hole formation is a robust prediction of the general Read More …

Are you ready to explore the X-ray Universe?

Welcome to CLAXSON!

(Classification of X-ray Sources for Novices)

CLAXSON is a platform that trains you to identify new objects observed in the X-ray sky with the European Space Agency X-ray telescope XMM-Newton. Be the first to find new supermassive black holes, stars, galaxies and other exotic objects in observations taken over the last 20 years, and help astronomers unravel the mysteries of the X-ray sky.
