Teen students spot a mysterious X-ray source

During a EXTraS workshop, highschool students discover a mysterious X-ray flare. The discovery led to a publication on the journal Astronomy&Astrophysics that you can read here, on arXiv or here, on A&A.

 

This finding produced a broad echo in the media: you can read more on the journal Nature and on the European Commission websites. You might also want to read the ESA press release (in English) or the news on Media INAF (in Italian).
