Saturn’s weird wobbly moon, Mimas

Ithaca - Saturn’s moon Mimas is already an oddity, being the most cratered object in the Solar System and likened to the Death Star of Star Wars fame. But new research this week points to Mimas being even weirder than previously thought.

Charlottesville - A team of US-based astronomers has identified an ancient stellar remnant, a white dwarf star so cool that it’s caused carbon to crystallize effectively producing an Earth-sized diamond in space.

Molecule essential for water found in dying stars

New evidence suggests that some dying stars contain OH+ which can be used as a building block for water. This lends more credibility to the argument for additional life in the universe.

This artist’s impression shows exocomets orbiting the star Beta Pictoris. Astronomers analysing observations of nearly 500 individual comets made with the HARPS instrument at ESO’s La Silla Observatory have discovered two families of exocomets around this nearby young star. The first consists of old exocomets that have made multiple passages near the star. The second family, shown in this illustration, consists of younger exocomets on the same orbit, which probably came from the recent break

Bridging Cities of Galaxies: Planck has discovered a bridge of hot gas connecting galaxy clusters Abell 399 (lower center) & Abell 401 (top left). The galaxy pair is located about a billion light-years from Earth. The gas bridge extends approximately 10 million light-years between them. The image shows the two galaxy clusters as seen at optical wavelengths with ground-based telescopes & through the Sunyaev-Zel'dovich effect (in orange) with the Planck satellite.

The ESO Very Large Telescope (VLT) during observations. A reddish laser beam is launched to create an artificial star at an altitude of 90 km in the Earth´s mesosphere. This Laser Guide Star (LGS) allows astronomers to remove the effects of atmospheric turbulence, producing images almost as sharp as if the telescope were in space.
