COROT discovers smallest exoplanet yet, with a surface to walk on

Feb 4th, 2009 | By admin | Category: Physics, technology

COROT has found the smallest terrestrial planet ever detected outside the Solar System. The amazing planet is less than twice the size of Earth and orbits a Sun-like star. Its temperature is so high that it is possibly covered in lava or water vapour. About 330 exoplanets have been discovered so far, most of [...]

Biggest breach of Earth’s solar storm shield discovered

Dec 20th, 2008 | By admin | Category: Physics

GREENBELT, Md. — Earth’s magnetic field, which shields our planet from particles streaming outward from the Sun, often develops two holes that allow the largest leaks, according to researchers sponsored by NASA and the National Science Foundation.
“The discovery overturns a long-standing belief about how and when most of the solar particles penetrate Earth’s magnetic field, [...]



Mystery of missing hydrogen

Nov 29th, 2008 | By admin | Category: Physics

Something vital is missing in the far distant reaches of the Universe: hydrogen - the raw material for stars, planets and possible life.
The discovery of its apparent absence from distant galaxies by a team of Australian astronomers is puzzling because hydrogen gas is the most common constituent of normal matter in the Universe.
If anything, [...]



India on the Moon, national flag on lunar surface

Nov 14th, 2008 | By admin | Category: Physics

Bangalore, Nov 14 (PTI) India marked its presence on Moon tonight to be only the fourth nation to scale this historic milestone after a Moon Impact Probe with the national tri-colour painted successfully landed on the lunar surface after being detached from unmanned spacecraft Chandrayaan-1.
Joining the US, the erstwhile Soviet Union and the European Union, [...]



Complex systems and Mars missions help understand how life began

Nov 14th, 2008 | By admin | Category: Physics

Understanding how life started remains a major challenge for science. At a European Science Foundation (ESF) and COST ‘Frontiers of Science’ conference in Sicily in October, scientists discussed two new approaches to the problem. The first applies complex systems theory to the chemistry that preceded early life. The second involves studying Mars, which may yield [...]



Planetary “first family” discovered by astronomers using Gemini and Keck Observatories

Nov 14th, 2008 | By admin | Category: Physics

First direct images of a planetary familly around a normal star observed
Astronomers using the Gemini North telescope and W.M. Keck Observatory on Hawaii’s Mauna Kea, the tallest mountain in the Hawaiian chain, have obtained the first-ever direct images identifying a multi-planet system around a normal star.
The Gemini images allowed the international team to make the [...]
