Mini-jets make the Top 10!

An image taken with Cassini's narrow angle camera just after the spacecraft entered orbit around Saturn on 1 July 2004.  The inset shows presence of a "mini-jet" approximately 55km long emanating from the bright core of Saturn's F ring. These features are caused by the gentle (about 2 m/s) impact of icy objects with the core.  QMUL astronomers have shown that there are about 500 examples of such features detectable in the images taken by Cassini's cameras.

Work carried out by planetary scientists in the Astronomy Unit has been chosen as one of the Top 10 Science Highlights of NASA's Cassini mission in 2012.  Nick Attree, Carl Murray, Nick Cooper and Gareth Williams reported their work on trails, or "mini-jets", in Saturn's peculiar F ring in April 2012.  The image was taken with Cassini's narrow angle camera just after the spacecraft entered orbit around Saturn on 1 July 2004.  The inset shows presence of a "mini-jet" approximately 55km long emanating from the bright core of Saturn's F ring.  These features are caused by the gentle (about 2 m/s) impact of icy objects with the core.  The QMUL astronomers have shown that there are about 500 examples of such features detectable in the images taken by Cassini's cameras and provided an explanation for their unusual properties.

VISTA creates huge nine-gigapixel zoomable image of 84 million stars

VISTA creates huge nine-gigapixel zoomable image of 84 million stars

A nine-gigapixel zoomable image of 84 million stars has been created by an international team of astronomers using the UK-built VISTA infrared survey telescope at ESO’s Paranal Observatory. The image is so large that, if printed with the resolution of the average book, it would be nine metres long and seven metres tall. The huge dataset contains ten times more stars than previous studies and is a major step forward for the understanding of our home galaxy, the Milky Way.

Glittering Trails

PASADENA, Calif. - Scientists working with images from NASA's Cassini spacecraft have discovered strange half-mile-sized (kilometer-sized) objects punching through parts of Saturn's F ring, leaving glittering trails behind them.
