CoRoT-9b

'Cool Jupiter' widens search for exoplanets

Thursday, 18 March 2010

Astronomers have found a temperate planet the size of Jupiter that whips around its star at close proximity.


Solar storm

Solar storms create 'killer electrons'

Thursday, 18 March 2010

'Killer electrons' - electrons circling Earth that wreck satellites and can cause cancer in astronauts - are created when Solar storms create shockwaves in the Earth's protective magnetic bubble, scientists said.


Ancient aurora

Early Earth embroiled in constant solar storm

Friday, 5 March 2010

A weak magnetic field and powerful solar wind stripped water from the early Earth's atmosphere 3.5 billions years ago and created stunning auroras, scientists said.


Moon

Ice discovered on Moon's north pole

Tuesday, 2 March 2010

A radar aboard an Indian spacecraft has detected craters filled with ice on the Moon's north pole, NASA scientists said.


Mars Rocket

To Mars in 39 days

Tuesday, 2 March 2010

A journey from Earth to Mars could eventually take just 39 days - cutting current travel time nearly six times - according to a rocket scientist who has the ear of U.S. space agency NASA.


Star Cluster

Milky Way brimming with alien stars

Monday, 1 March 2010

At least a quarter of the star clusters in the Milky Way were born elsewhere and have migrated into our galaxy, researchers say.


Murchison meteorite

Meteorite contains complex organic molecules

Tuesday, 16 February 2010

Previously unknown organic molecules have been discovered in a 40-year-old meteorite, suggesting the early Solar System contained a soup of highly complex organic chemistry long before life appeared.


Dylla and Falk

U.S. physics prize won by COSMOS writer

Friday, 12 February 2010

Dan Falk, a Canadian science writer, has won the American Institute of Physics' prestigious Science Writing Award for a cover story in Cosmos.


Dark matter

Hints of dark matter detected on Earth

Friday, 12 February 2010

There is a 75% chance that scientists have detected dark matter, in the form of weakly interacting massive particles (WIMPs), at an experiment deep underground in Minnesota, USA.


peculiar galaxy

Older galaxies more peculiar, census shows

Monday, 8 February 2010

The most common type of galaxy changed from a "peculiar" shape six billion years ago to a typical spiral shape today, and may indicate galaxies have a more violent past than previously believed.


Sunspots

Solar flares back, but oddly small

Friday, 5 February 2010

After a long silence, the Sun erupted in an unusual pattern of small solar flares, said an Australian astrophysicist, which may provide a unique opportunity to predict when bigger solar flares will erupt.


Gamma-ray flash

Tiny 'Firefly' satellite to study terrestrial gamma-ray flashes

Monday, 1 February 2010

Gamma-ray flashes that occur in the Earth's atmosphere have been a mystery for over 15 years. But now NASA scientists will launch the first dedicated survey.


From the Moon

Obama abandons plan to return to the Moon

Friday, 29 January 2010

President Barack Obama's 2011 budget, to be submitted to U.S. Congress Monday, will propose abandoning a program to return NASA astronauts to the Moon, two Florida newspapers reported.


Ribbon of particles

Mysterious band of particles holds clues to Solar System's future

Monday, 25 January 2010

A ribbon of particles at the Solar System's edge "shocked" NASA researchers. Now they say it's a reflection off a strong galactic magnetic field, and holds the clues to the future of the Solar System.


galaxy shapes

Galaxies shaped by dark past

Friday, 22 January 2010

Using a cosmological model that includes dark energy and dark matter, two American astrophysicists correctly predicted the shapes and proportions of the types of galaxies in the universe.
