First 'Ghost Particle' Image of Milky Way

Scientists have revealed a uniquely different image of our galaxy by determining the galactic origin of thousands of neutrinos -- invisible 'ghost particles' which exist in great quantities but normally pass straight through Earth undetected. The neutrino-based image of the Milky Way is the first ...

Earliest Strands of the Cosmic Web

Galaxies are not scattered randomly across the universe. They gather together not only into clusters, but into vast interconnected filamentary structures with gigantic barren voids in between. This 'cosmic web' started out tenuous and became more distinct over time as gravity drew matter ...

Gravitational Waves from Colossal Black Holes Found Using 'Cosmic Clocks'

You can't see or feel it, but everything around you -- including your own body -- is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our galaxy. New results are the first evidence of the gravitational wave background -- a sort of soup ...

Life After Death: Astronomers Find a Planet That Shouldn't Exist

The star would have inflated up to 1.5 times the planet's orbital distance -- engulfing the planet in the process -- before shrinking to its current size at only one-tenth of that ...
