Helix nebula, HST image Featured 31 Mar 2005 Print

Helix nebula, HST image

Helix Nebula. Hubble Space Telescope image of the Helix planetary nebula (NGC 7293). This comprises shells of gas cast off a Sun-like star near the end of its life. The colours are due to gases in the shells being ionised by radiation from the central star that ejected them. The blue colour comes from oxygen and the red from hydrogen and nitrogen. Despite its ring shape, it is thought that the nebula is actually a cylinder aligned end on to Earth. This is one of the nearest planetary nebulae to Earth, lying 650 light years away in the constellation Aquarius. It is 3 light years in diameter, and appears half a Moon-width wide

Starfield centred on the Southern Cross Featured 31 Mar 2005 Print

Starfield centred on the Southern Cross

Splendid starfield centred on the constellation of the Southern Cross (Crux Australis). It shows an area of our galaxy, the Milky Way, extremely rich in star clusters, dark and bright (pink) nebulae. Four bright stars at centre left identify the familiar cross-shaped asterism in the Southern Cross. The two brightest stars at centre far left are Alpha (closer to the edge) and Beta Centauri. The larger pink area at centre right is Eta Carinae, a giant emission nebula having a diameter of about 300 light years. Omega Centauri, the largest and brightest globular star cluster in the sky, is the white, round object at top left

Researcher and snake Featured 31 Mar 2005 Print

Researcher and snake

Snake research. Researcher holds a Malaysian pit viper (Calloselasma rhodostoma) before milking its venom. The venom contains an anticoagulant drug which is being studied for use in treating stroke patients. The drug, Ancrod, improves blood flow by reducing the amount of fibrinogen (a clotting protein) in the blood plasma. Strokes occur when the blood supply to part of the brain is cut off by a blockage or bleeding in the brain. They can lead to brain damage and are a leading cause of death. Ancrod may reduce the extent of brain damage and lower the mortality rate. This work is being done by Knoll AG, a division of BASF Pharma, in Ludwigshafen, Germany
