... In the picture it looks like a peaceful place, but astronomers have spotted the violent explosions of two stars in this galaxy over the past 30 years. The explosion of a massive star is called a supernova. ... The first supernova that was spotted in this galaxy was discovered by professional astronomers, using a big telescope that is based in the desert in the country Chile in South America. ... Any changes in the brightness of an area of the galaxy could mean that a star has exploded. ...

It is possible to piece together the processes that have shaped the observed characteristics of a galaxy by studying its stars in detail. The Large Magellanic Cloud (LMC) is an excellent candidate for this type of study because of its favourable viewing angle and ongoing star formation. I present the results of high-resolution VLT/FLAMES observations of ~80 red giant stars around star cluster NGC 1846, located in the disc of the LMC. ...

Next: Pulsations Up: PHYSICAL CHARACTERISTICS Previous: PHYSICAL CHARACTERISTICS . The fundamental properties of RCBs may be deduced from their spectra at maximum light. ... The properties of a stellar atmosphere may be measured from both the large-scale features - the broad-band flux distribution - and the detailed spectrum of absorption lines. ...

... 2008 September 10 . The Anthe Arc around Saturn . Credit: Cassini Imaging Team , SSI , JPL , ESA , NASA . ... Since the arc occupies the same orbit as the small moon Anthe , a leading hypothesis holds that the arc was created by, and is replenished by, meteor impacts on Anthe. Similar arcs have been previously discovered, including an arc associated with the small Saturnian moon Methone , one arc related to Saturn's G ring , and several arcs orbiting Neptune . ...

... This year's eclipse is unique in duration. ... Although, at the present time, there are 6 solar observatories belonging to leading space agencies in orbit around the Earth, the eclipse of 22 July, 2009, will only be seen by two of them: the Russian CORONAS-PHOTON satellite equipped with TESIS telescopes and Japan's HINODE satellite fitted with an XRT space telescope. ... TESIS will be the first of the two devices (and the very first on Earth) to witness the solar eclipse. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... STScI-PRC99-13 HUBBLE CLICKS IMAGES OF IO SWEEPING ACROSS JUPITER While hunting for volcanic plumes on Io, NASA's Hubble Space Telescope captured these images of the volatile moon sweeping across the giant face of Jupiter. Only a few weeks before these dramatic images were taken, the orbiting telescope snapped a portrait of one of Io's volcanoes spewing sulfur dioxide "snow." ... Astronomers increased the color contrast and added false colors to the image to make the faint plume visible. ...
