Studies by two independent groups from the US and the Netherlands indicate that the observed excess of gamma rays from the inner galaxy likely comes from a new source rather than from dark matter. The best candidates are rapidly rotating neutron stars, which will be prime targets for future searches. The Princeton/MIT group and the Netherlands-based group used two different techniques...
Gemini South by the full moon News.science360.gov.org
This picture taken with a fish-eye lens from inside the Gemini South dome shows the telescope nested in its altazimuth mount, pointing just high enough so that its monstrous 8-meter primary mirror is visible. The sky seen through the dome’s open vent gates which remain open during observing runs--when winds are relatively light-- to help equalize air temperatures inside and outside th...

The old adage "what goes up must come down" even applies to an immense cloud of hydrogen gas outside our Milky Way galaxy. First discovered in the 1960s, the comet-shaped cloud is 11,000 light-years long and 2,500 light-years across. If the cloud could be seen in visible light, it would span the sky with an apparent diameter 30 times greater than the size of ...

Some of the Milky Way's "celebrity stars" opulent, attention-getting, and short-lived can be found in this Hubble Space Telescope image of the glittering star cluster called Trumpler 14. It is located 8,000 light-years away in the Carina Nebula, a huge star-formation region in our galaxy. Because the cluster is only 500,000 years old, it has one of the highes...
