The Fate of a Dark Matter Theory Hinges on These Unidentified X-Rays

Despite decades of searching, no one has yet cracked the mystery of dark matter. One hypothesis to explain it relies on strange x-rays emanating from distant galaxies and galaxy clusters, but a new paper appears to rule out dark matter as producing these mysterious x-rays. Read More >>

Oh Yeah, Betelgeuse Is Definitely Looking Weirder

At this point, we’re all crossing our fingers that the dying star Betelgeuse will hurry up and explode already, because who doesn’t love a good show? The red giant star (visible in the constellation Orion) has been growing dimmer since late last year, leading many to speculate it could soon go supernova. Scientists operating the European Southern Observatory’s Very Large Telescope have released new images of the supergiant star – and yep, it looks weird. Read More >>
