Observations made with NASA's newly refurbished Hubble Space Telescope of a nearby supernova are allowing astronomers to measure the velocity and composition of "star guts" being ejected into space following the explosion, according to a new study.

Recipe for water: Just add starlight

The European Space Agency's Herschel infrared space observatory has discovered that ultraviolet starlight is the key ingredient for making water in space. It is the only explanation for why a dying star is surrounded by a gigantic cloud of hot water vapor.

Ultraviolet source helps NASA spacecraft measure the origins of space weather

With a brilliant, finely tuned spark of ultraviolet light, a physicist has helped NASA scientists successfully position a crucial UV sensor inside a space-borne instrument to observe a "hidden" layer of the Sun where violent space weather can originate.

Navigation satellites contend with stormy Sun

Just as we grow used to satellite navigation in everyday life, media reports argue that a coming surge in solar activity could render satnav devices useless, perhaps even frying satellites themselves. Is it true? No.

New solar prediction system gives time to prepare for the storms ahead

A new method of predicting solar storms that could help to avoid widespread power and communications blackouts costing billions of pounds has been launched by researchers in the UK.

Superwind Galaxy NGC 4666

The galaxy NGC 4666 takes pride of place at the centre of this new image, made in visible light with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. NGC 4666 is a remarkable galaxy with very vigorous star formation and an unusual "superwind" of out-flowing gas. It had previously been observed in X-rays by the ESA XMM-Newton space telescope, and the image presented here was taken to allow further study of other objects detected in the earlier X-ray observations.
