A cosmic story of Dr. Jekyll and Mr. Hyde: A double star system appears to change its behavior rapidly and unpredictably!

April 5, 2020April 5, 2020 Ektoras PouliasisArticle

Astronomers have detected a double (or a binary as it is called) star system that it is flip-flopping between two alter egos using NASA’s Chandra X-ray Observatory and the National Science Foundation’s Karl F. Jansky Very Large Array (VLA). This Read More …

Case: A cosmic homicide!

April 2, 2020April 2, 2020 Ektoras PouliasisArticle

An artistic view of a star tearing apart by a black hole. Image credit: NASA. Astronomers solved the mystery and found the perpetrator, an intermediate-mass black hole that was caught in action tearing apart a star that just happened to Read More …

Testing “Theory of Everything” through Chandra X-ray Observatory!

March 20, 2020April 2, 2020 Ektoras PouliasisArticle

Source: NASA / CXC / University of Cambridge / C. Reynolds et al. The “Theory of everything” is a big idea that all forces, particles and interactions in Universe connect with each other under the same framework of physics with Read More …

Scratching the edge of the Universe: the most distant Blazar yet!

March 19, 2020 Ektoras PouliasisArticle

Scientists have detected an ancient super-massive black hole with the name PSO J030947.49+271757.31. Its distance was calculated 13 billion light-years from Earth making it officially the most distant blazar ever observed with a relativistic jet pointing directly toward Earth. The Read More …

BOOM! The biggest known explosion ever in the Universe’s history!

March 17, 2020March 17, 2020 Ektoras PouliasisArticle

Scientists, while studying a very distant cluster of galaxies, have discovered the biggest explosion ever seen in the Universe since the Big Bang! The energy released from this explosion is five times larger than the previous record holder, which occurred Read More …

XMM-Newton: Mapping the dynamic behaviour and surroundings of a black hole

February 10, 2020February 10, 2020 Vasileia Aspasia MasouraArticle

ESA’s XMM-Newton X-ray observatory has used, for the first time, the reverberating echoes of X-ray radiation in order to map the dynamic behaviour and surroundings of a black hole (BH). This emission is the result of the infalling material into Read More …

An X-ray detection of star formation in a strongly lensed galaxy

October 19, 2019October 19, 2019 Vasileia Aspasia MasouraArticle

Astronomers reported an X-ray detection of star formation in a highly magnified, strongly lensed galaxy. The system is a low-mass, low-metallicity starburst with increased X-ray emission and is an infant galaxy! Specifically, it was formed when our universe was less Read More …

Nobel Prize in Physics 2019!

October 9, 2019 Vasileia Aspasia MasouraArticle

Like every year, the winners of the Nobel Prize in Physics were announced for their contributions to science. The benchmark for 2019 was the broader field of Astrophysics, as Nobel shared with three scientists for their contributions to Astronomy and Read More …

Are you ready to explore the X-ray Universe?

Welcome to CLAXSON!

(Classification of X-ray Sources for Novices)

Now available in EN, FR, ES and GR!

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.

Invitation to submit news

Astronomers are invited to advertise their work and/or recent results in our website. Publications/news related to High Energy Astrophysics are of particular interest.
