(Space Fellowship) Cluster and Starforming Region Westerlund 2

Located 20,000 light-years away in the constellation Carina, the young cluster and starforming region Westerlund 2 fills this cosmic scene. Captured with Hubble's cameras in near-infrared and visible light, the stunning image is a celebration of the 25th anniversary of the launch of the Hubble Space Telescope on April 24, 1990. The cluster's dense concentration of luminous, massive stars is about 10 light-years across. Strong winds and radiation from those massive young stars have sculpted an [...]

(ScienceDaily) Examining Einstein: Precise experiments using lasers and clocks in space

Albert Einstein tells us that clocks run slower the deeper they are in the gravitational potential well of a mass – the closer they are to a heavenly body, for example. This effect is described by General Relativity Theory as the gravitational red shift – it is detectable in spectral lines that shift toward the red end of the spectrum. General Relativity Theory also predicts that the rates of all clocks are equally influenced by gravitation independent of how these clocks are physically or technically constructed. However, more recent theories of gravitation allow for the possibility that the type of clock indeed influences the degree of gravitational red shift. To test this theory-about-a-theory, scientists have launched a high-altitude research rocket to send various types of clocks into space and back again.   

(Discovery News) Hubble at 25: Brief History of the Hubble Space Telescope

(ScienceDaily) To flare or not to flare: The riddle of galactic thin to thick disk solved

A long-standing puzzle regarding the nature of disk galaxies has finally been solved by a team of astronomers using state-of-the-art theoretical models. The new study shows that groups of stars with the same age always flare as the result of massive galactic collisions. When taken all together, these flares, nested like the petals of a blooming rose, puff up the disk and constitute what astronomers call the “thick” disk.   

(ScienceDaily) Giant cosmic tsunami wakes up comatose galaxies

Galaxies are often found in clusters, which contain many 'red and dead' members that stopped forming stars in the distant past. Now an international team of astronomers have discovered that these comatose galaxies can sometimes come back to life. If clusters of galaxies merge, a huge shock wave can drive the birth of a new generation of stars -- the sleeping galaxies get a new lease of life.

Also known as sea sparkles or blue tears, the marine plankton's bioluminescence is stimulated by wave motion. City lights along the coast of mainland China shine beneath low clouds in the west but stars and the faint Milky  [...]

(Space Fellowship) Astronomers Find Runaway Galaxies

Cambridge, MA - We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy forever. Now, astronomers have spotted 11 runaway galaxies that have been flung out of their homes to wander the void of intergalactic space. "These galaxies are facing a lonely future, exiled from the galaxy clusters they used to live in," said astronomer Igor Chilingarian (Harvard-Smithsonian Center for Astrophysics/Moscow State University). Chilingarian is the lead aut [...]
