The Very Large Telescope Interferometer (VLTI) at ESO s Paranal Observatory in Chile has obtained the sharpest view ever of the dusty disk around the close pair of aging stars IRAS 08544-4431. For the first time, such disks can be compared to the disks around young stars and they look surprisingly similar. ... The inset shows the VLTI reconstructed image, with the brighter central star removed. The background view shows the surroundings of this star in the constellation Vela the Sails. ...

The ESA/ESO Astronomy Exercise Series 2 . The Distance to Messier 100 as Determined by Cepheid Variable Stars . ... The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...
