Sneezing comet and lines in space.

A new galaxy in the constellation Hydra, dunes seen on Mars and natural habitats from space. In February 2015, the Rosetta probe of the European Space Agency has captured in a surprise explosion on the comet 67P. The plume of ice and dust may have been caused by a landslide.


The margin of the perennial northern ice cap of Mars shows the interior of the cap layers, each with a different composition of water, dust and debris. It is likely that the various layers correspond to different climatic conditions.


The lines on the surface of Saturn’s moon Dione reveal the ancient tectonic movements of the satellite. The scholars are analyzing to understand how the moon is heated and cooled from its formation.


This digital model of the Martian soil created from data of the Mars Reconnaissance Orbiter shows a field of dunes in Becquerel Crater. The tops of the dunes rises to 700 meters from the crater floor.


The Hubble telescope took this image of NGC 5264, a dwarf galaxy located 15 million years away in the constellation Hydra. The blue spots are areas of formation of new stars, caused by the passage of other galaxies close to NGC 5264.


Landsat 8 took this picture of the barrier islands near the Cape Hatteras National Seashore, North Carolina. The coast provides a habitat for many species of birds and sea creatures.
