XMM-Newton’s Xray tagged posts

Scientists have finally confirmed a powerful coronal mass ejection from another star, using LOFAR radio data paired with XMM-Newton’s Xray insights. The eruption blasted into space at extraordinary speeds, strong enough to strip atmospheres from close-orbiting worlds. This suggests planets around active red dwarfs may be far less hospitable than hoped.

Astronomers working with the European Space Agency’s XMM-Newton observatory and the LOFAR radio telescope have obtained clear evidence of a violent burst of material hurled into space by a distant star. The outflow was strong enough that any nearby planet in its path would likely have its atmosphere stripped away.

This burst was identified as a coronal mass ejection (CME), a typ...
