Moon and planets on Catalonia
Next month, Venus and Jupiter appear exceptionally close in the sky. The planetary alignment can be seen easily with the naked eye as Venus look brighter than any star in the background and Jupiter will be nearly as much. To see the lineup just have to look west after sunset. The closest approach will take place on March 15: only three degrees of separation between the two planets . Viewed from Earth, Venus will almost in front of Jupiter.
In the picture, a composition made last week in Catalonia ( Spain ), the crescent Moon is to the right of Venus and, at the top, Jupiter. The two areas distant sunlit were photographed behind a sculpture of the legendary battle between a warrior and a dragon .
Forum Asterisk APOD is a gallery of conjunctions , where invited to contribute. The next conjunction of Jupiter and Venus will be in May 2013.

The tails of the comet opposite Garradd
Why Garradd comet has two tails? The dust tail of Comet Garradd, visible on the left, consists of chunks of ice and dust that follow the comet in its orbit around the Sun The ion tail of comet Garradd, visible to the right, consists of gas ionized ejected from the Sun by the solar wind.
Most comets show two tails , but rarely seem to point in almost opposite directions. The comet Garradd currently displayed opposite tails due to the angle of view from Earth. This image , captured last week, shows the queue slightly yellow powder as its dust reflects achromatically sunlight, while the ion tail slightly blue color shines ions by carbon monoxide to more efficiently reflect the blue sunlight.
In the center and surrounding the comet nucleus is the point dyed green as it is a mixture of dust and gases emitted by the green include cyanogen.
Although currently underway to drift away from the Sun, the comet Garradd will make its closest approach to Earth next week.

The Wild past the most massive galaxies
Using the APEX telescope, a team of astronomers has found a clear relationship found so far among the most powerful bursts of star formation in the early universe and the most massive galaxies found today. Galaxies, starbursts with dramatic flourish in the early universe, witnessed the sudden interruption of the birth of stars, leaving them with the current appearance: massive galaxies - but passive - with old stars. Astronomers also have a possible culprit for the sudden end of the bursts of star formation: the birth of supermassive black holes.
Astronomers have combined observations of the ESO LABOCA operated in the 12-m telescope Atacama Pathfinder Experiment (APEX) [1] , with measures taken by the telescope of ESO Very Large Telescope and the Spitzer Space Telescope NASA , among others, to see how bright these distant galaxies cluster together in groups.
The closer cluster galaxies are the most massive halos of dark matter - invisible matter that makes up most of the mass of the galaxies. These new results are the most precise measurements ever made of clusters for this type of galaxy.

Track of Exoplanets on Sun Curious Chemistry
A groundbreaking survey of 500 stars, 70 of which are known to harbor planets, has been linked to former "lithium mystery" observed in the Sun to the presence of planetary systems. Using the HARPS spectrograph on ESO's successful, a team of astronomers has discovered that sun-like stars that host planets have destroyed their lithium much more efficiently than stars without planets. This finding not only sheds light on the lack of lithium in our stars, but also provides astronomers with a very efficient way of finding stars with planetary systems.
"For nearly 10 years we have tried to discover what distinguishes stars with planetary systems lacking these premiums," says Garik Israelian, lead author of a paper appearing this week in the journal Nature. "We have now found that the amount of lithium in solar-like stars depends on whether or not planets."
