... Astronomy news . ... Double Engine Fuels Star's Remarkable Nebula . ESO has just released a stunning new image of a field of stars towards the constellation of Carina (the Keel). ... Interactions in this double system, surrounded by a dusty disc, may be the engine fuelling the star s remarkable nebula. The new image, showing a very rich field of stars towards the Carina arm of the Milky Way, is centred on the star HD 87643, a member of the exotic class of B[e] stars [1]. ...

Many intermediate-age star clusters in the Magellanic Clouds exhibit very unusual features in their colour-magnitude diagrams that suggest they may have formed their stars over periods spanning hundreds of millions of years per cluster. ... Nonetheless, this interpretation is enticing in the context of the formation of ancient globular clusters, which almost always exhibit puzzling abundance patterns that apparently require multiple episodes of star formation to explain. ...

Astronomers usually measure the flux of an object by collecting light with a telescope, sending it through a known filter, and then determining the power. ... But astronomers usually give their photometric results in terms of magnitudes. ... Astronomers define an absolute magnitude that is independent of the distance of a star and only depends on the intrinsic properties of the object: the absolute magnitude is the magnitude the star would have if it were 10 parsecs away from the Earth. ...

We report on recent observations of molecular clouds in the tidal Magellanic Bridge; specifically, the Ы?kpc-long, tidally extended "tail" of the Small Magellanic Cloud. In particular, we identify an unusually high 12CO(3-2)/12CO(1-0) ratio of 2-3 to 1, toward one of the clouds, suggesting a warm and dense molecular material associated with imminent or current formation of stars. ...
