Hubble’s Dazzling Display of Galaxies

Hubble’s Dazzling Display of Galaxies This busy image is a treasure trove of wonders. Bright stars from the Milky Way sparkle in the foreground, the magnificent swirls of several spiral galaxies are visible across the frame, and a glowing assortment of objects at the center makes up a massive galaxy…

X-ray “heartbeats” of two different black holes that ingest gas from their companion stars. GRS 1915 has nearly five times the mass of IGR J17091, which at three solar masses may be the smallest black hole known. Credits: NASA's Goddard Space Flight Center

NASA’s Rossi X-ray Timing Explorer Leaves Scientific ‘Treasure Trove’

NASA’s Rossi X-ray Timing Explorer Leaves Scientific ‘Treasure Trove’ NASA’s decommissioned Rossi X-ray Timing Explorer (RXTE) satellite re-entered Earth’s atmosphere on April 30. Orbiting for more than 22 years, the 6,700-pound satellite operated from 1996 to 2012, providing scientists with an unprecedented look into the extreme environments around neutron stars…

Hints of extra dimensions in gravitational waves?

Hints of extra dimensions in gravitational waves? Researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam found that hidden dimensions – as predicted by string theory – could influence gravitational waves. In a recently published paper they study the consequences of extra dimensions on these…
