Feeding of Teenage Galaxies

New observations which was made by using ESO’s Very Large Telescope will help to better understand the growth of teenage galaxies. In the biggest survey of its kind astronomers have found that galaxies changed their eating habits during their teenage years the period from about 3 to 5 billion years after the Big Bang. At the start of this phase smooth gas flow was the preferred snack, but later, galaxies mostly grew by cannibalising other smaller galaxies. Galaxies examined through the VLT are located in a tiny patch of sky more than 40 million light-years away, in the constellation of Cetus.

Helix Nebula Glows Like Giant Golden Eye

The Helix Nebula glows like a giant golden eye in the sky in the image, released on January 19, 2012 by the European Southern Observatory (ESO). This picture, taken in infrared light, reveals strands of cold nebular gas that are invisible in images taken in visible light, and brings to light a rich background of stars and galaxies. The picture was captured by ESO’s VISTA telescope, at the Paranal Observatory in Chile. The Helix Nebula is one of the closest and most remarkable examples of a planetary nebula. The Helix Nebula lies in the constellation of Aquarius, about 700 light-years away from Earth. This strange object formed when a star like the sun was in the final stages of its life.

Spiral Galaxy NGC 3521

With the help of the FORS1 instrument on the European Southern Observatory’s Very Large Telescope at the Paranal Observatory in Chile astronomers was taken the picture of the nearby galaxy NGC 3521. The large spiral galaxy lies in the constellation of Leo (The Lion), and is only 35 million llight-years from Earth.

The First Detected Hydrogen Peroxide in the Interplanetary Space

With the help of a radio telescope APEX scientists at European Southern Observatory in Chile (ESO) detected the presence of hydrogen peroxide in the cold gaseous nebula in the constellation Ophiuchus at a distance of 400 light years from Earth.Hydrogen peroxide (H202) is extremely active compound, which plays an important role in biological and chemical processes on Earth.
