A dead star 730 light years away appears to be forming a powerful structure around itself — and despite their best efforts, astronomers aren’t sure how. The cosmic corpse, designated RXJ0528+2838, is ...

A new study reveals a rare-breaking white dwarf star, dubbed RXJ0528+2838, that is somehow generating a rainbow-like "bow shock" as it zooms through the Milky Way. The cosmic zombie is also ripping ...
