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 ...

Exoplanet May Reveal Secrets About the Edge of Habitability

How close can a rocky planet be to a star, and still sustain water and life? A recently discovered exoplanet may be key to solving that ...

Clean, Sustainable Fuels Made 'from Thin Air' and Plastic Waste

Researchers have demonstrated how carbon dioxide can be captured from industrial processes -- or even directly from the air -- and transformed into clean, sustainable fuels using just the energy from the ...

For Experimental Physicists, Quantum Frustration Leads to Fundamental Discovery

A team of physicists recently announced that they have discovered a new phase of matter. Called the 'chiral bose-liquid state,' the discovery opens a new path in the age-old effort to understand the nature of the physical ...
