Bursts of Light Discovered in a Suspected Binary Protostar

  Two of NASA’s Great Observatories, the Spitzer and Hubble space telescopes, have teamed up to uncover a mysterious infant star that behaves like a police strobe light. This Hubble Space Telescope monochromatic-color image resolves the detailed structure around the protostar, consisting of two cavities that are traced by light scattered off their edges above [continue reading]

The Largest-Known Spiral Galaxy Revealed

  The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil has crowned it the largest-known spiral, based on archival data from NASA’s Galaxy Evolution Explorer (GALEX) mission, which has since been loaned to the California Institute [continue reading]

Cosmic Blender Churns Galaxy Cluster

  Scientists have used a suite of X-ray observations to find evidence of large scale swirling gas motion in the Perseus galaxy cluster. The Perseus Cluster, located 237 million light-years away in the constellation of Perseus, contains thousands of galaxies immersed in a vast cloud of multimillion degree gas. Image Credit: Jean-Charles Cuillandre (CFHT) & Giovanni [continue reading]

41 New Exoplanets Discovered!

  Two newly submitted studies verify 41 new transiting planets in 20 star systems. These results may increase the number of Kepler’s confirmed planets by more than 50 percent: to 116 planets hosted in 67 systems, over half of which contain more than one planet. The papers are currently under scientific peer-review. The diagram shows [continue reading]

Halo of Neutrinos Alters Physics of Supernovae

  Sparse halos of neutrinos within the hearts of exploding stars exert a previously unrecognized influence on the physics of the explosion and may alter which elements can be forged by these violent events. The titanic supernova, called SN 1987A, blazed with the power of 100 million suns for several months following its discovery on [continue reading]

Star Clusters in the Tarantula Nebula on a Collision Course

  Astronomers using data from NASA’s Hubble Space Telescope have caught two clusters full of massive stars that may be in the early stages of merging. The clusters are 170,000 light-years away in the Large Magellanic Cloud, a small satellite galaxy to our Milky Way. This is a Hubble Space Telescope image of a pair [continue reading]
