Older stars can birth planets
Recalculating the ages of young clusters of stars seems to solve apparent discrepancies between star ages and planetary disk formation times, according to Dr Tim Naylor of Exeter University, who presented his work at the European Week of Astronomy and Space Science.

Most distant starbursting galaxies discovered
Galaxies have been observed undergoing furious bursts of star formation during a very early period of the Universe, long before established models of galaxy formation predict that they should.

Will the Sun's decline affect climate change?
The lack of current solar activity came under the spotlight today at the European Week of Astronomy and Space Science. "Activity is at an all time low since the start of the space age," says Professor Mike Lockwood of the University of Southampton and the Rutherford Appleton Laboratory.

Are imaged planets really failed stars?
Most of the images of exoplanets released towards the end of 2008 may not be planets at all, according to new research presented at the European Week of Astronomy and Space Science being held at the University of Hertfordshire.

Organic 'Lego' molecules hint at origins of life's building blocks
An interstellar cloud of gas close to the galactic centre rich in a veritable soup of chemicals has produced its two most complex molecules yet, which are just a step away from organic molecules that are the basis of life as we know it.

Satellite galaxies knocking Newton
The behaviour of the Milky Way's satellite galaxies suggest that Newton's gravitation doesn't apply to them, so say a team of scientists from Germany, Austria and Australia. If this is the case then is a modification of gravity needed?

Energy ribbons cause explosive solar flares
Tight ribbons of energy on the Sun called sigmoids have been found to cause explosive solar flare events. X-ray telescopes can see these sigmoids in the Sun's corona (it's tenuous outer atmosphere), but models produced by scientists now explain how they form.

Video: Look for the Lyrids this week
The spring drought of meteor showers is over with the return of the Lyrids, peaking over the next few days. Shooting out of their radiant near Vega and out towards the southern horizon, their often bright, lingering trails are worth looking out for, as Greg Smye-Rumsby shows.

What's the big deal
about dust?
Dust has a habit of getting everywhere, as we all know. It's even found in space, but interstellar dust is much more important than the fluffy stuff that accumulates on your sideboard at home. Without interstellar dust, you and I and planet Earth wouldn't even exist.
