Did an ancient impact bowl Pluto over?
(Oct 6, 2007)
Pluto
and its large moon Charon
may have been bowled over when they were struck by wayward space rocks
in the past, a new study suggests. If so, NASA's New Horizons spacecraft
may find evidence of these rolls when it arrives at the distant worlds
in 2015.

Mirrors 'could deflect' asteroids
(Oct 6, 2007)
Flying mirrors could save earth from a catastrophic asteroid
collision, researchers have claimed. Up to 5,000 mirrors would be
used to focus a beam of sunlight on to the asteroid, melting the rock
and altering its orbital path away from earth. The announcement came
after a team at the University of Glasgow compared nine different
methods of deflecting near earth objects asteroids and comets.

Sun's 'twin' an ideal hunting ground for
alien life
(Oct 4, 2007)
Astronomers have found the most Sun-like star yet, and they say it
is an ideal place to hunt for alien civilisations. The star, called
HIP 56948, lies a little more than 200 light years from Earth. Its
size, mass, temperature, and chemical makeup are all so similar to
the Sun's that no measurable differences could be found in high-resolution
observations made by the 2.7-metre telescope at the McDonald Observatory
in Texas.

Though colder than Earth, Titan is tropical
in nature
(Oct 3, 2007)
If space travelers ever visit Saturn's
largest moon, they will find a tropical world where temperatures
plunge to minus 274 degrees Fahrenheit, methane rains from the sky
and dunes of ice or tar cover the planet's most arid regions. These
conditions reflect a cold mirror image of Earth's tropical and subtropical
climates, according to scientists at the University of Chicago.

Is a naked singularity lurking in our
Galaxy
(Oct 2, 2007)
Could a naked
singularity, the bare core of a black
hole, be sitting at the centre of our galaxy? A new study shows
how astronomers could detect such a brazen object – which is
so dense it would shred the known laws of physics.
