Liftoff! Curiosity Bound for
Mars
With NASA's Mars Science Laboratory (MSL) spacecraft sealed
inside its payload fairing, the United Launch Alliance Atlas V rocket
rides smoke and flames as it rises from the launch pad at Space Launch
Complex-41 on Cape Canaveral Air Force Station in Florida at 10:02 a.m.

Asteroid Lutetia
This image of the unusual asteroid Lutetia was taken
by ESA’s Rosetta probe during its closest approach in July 2010. Lutetia,
which is about 100 kilometres across, seems to be a leftover fragment of
the same original material that formed the Earth, Venus and Mercury. It is
now part of the main asteroid belt, between the orbits of Mars and
Jupiter, but its composition suggests that it was originally much closer
to the Sun.

Faraway Eris is Pluto's
Twin
 Dwarf planet sized up accurately as it blocks light
of faint star 26 October 2011
Astronomers have accurately measured the diameter of the faraway dwarf
planet Eris for the first time by catching it as it passed in front of a
faint star. This event was seen at the end of 2010 by telescopes in Chile,
including the Belgian TRAPPIST telescope at ESO’s La Silla Observatory.
The observations show that Eris is an almost perfect twin of Pluto in
size.

A Closeup View of the Giant
Asteroid Vesta.
In this image of Vesta, taken by NASA's Dawn spacecraft just
shortly before the beginning of high altitude mapping orbit, north is up
and the upper right corner is to the northeast. The spacecraft's distance
to Vesta's center is about 420 miles (680 kilometers), and the image
resolution is approximately 65 meters per pixel.

Fifty New
Exoplanets Discovered by HARPS
Richest haul of planets so far
includes 16 new super-Earths 12 September 2011
Astronomers using ESO’s world-leading exoplanet
hunter HARPS have announced a rich haul of more than 50 new exoplanets,
including 16 super-Earths, one of which orbits at the edge of the
habitable zone of its star. By studying the properties of all the HARPS
planets found so far, the team has found that about 40% of stars similar
to the Sun have at least one planet lighter than Saturn.

Oblique View of Warm Season Flows in Newton
Crater
An image combining orbital imagery with 3-D
modeling shows flows that appear in spring and summer on a slope inside
Mars' Newton crater. Sequences of observations recording the seasonal
changes at this site and a few others with similar flows might be evidence
of salty liquid water active on Mars today. Evidence for that possible
interpretation is presented in a report by McEwen et al. in the Aug. 5,
2011, edition of Science.
