XMM-Newton spies first clear X-ray flares from massive stellar lighthouse

In 2014, ESA’s XMM-Newton spotted X-rays emanating from the massive star Rho Ophiuchi A and, last year, found these to ebb and flow periodically in the form of intense flares – both unexpected results. The team has now used ESO’s Very Large Telescope to find that the star boasts a strong magnetic field, confirming its status as a cosmic lighthouse.
