ESA’s infrared Herschel Space Observatory has studied the dusty belt around the nearby star Fomalhaut. The dust appears to be coming from collisions that destroy up to thousands of icy comets every day.

2 of ESA’s space observatories have combined to create a multi-wavelength view of violent events taking place within the giant galaxy of Centaurus A. The new observations strengthen the view that it may have been created by the cataclysmic collision of two older galaxies.

An unprecedented survey of gravitationally lensed quasars, has used to measure the expansion history of the universe. The result provides strong evidence that the expansion of the universe is accelerating.

New anaysis of the planetary system around the star HD1080 that was known to have 6 planets orbiting it, has revealed 3 additional smaller planets. The new planets are 1,3x, 1,9x, and 5,1x the size of Earth, with orbital periods of 1, 10 and 68 days respectively. The system thus seems rather solarsystem-like, apart from the planets being much closer to their parent star
