NGC 2035 is an emission nebula located 160,000 light years from the Earth in the constellation Dorado.

The Large Magellanic Cloud is one of the closest galaxies to our own. Astronomers have now used the power of ESO’s Very Large Telescope to explore one of its lesser known regions. This new image shows clouds of gas and dust where hot new stars are being born and are sculpting their surroundings into odd shapes. But the image also shows the effects of stellar death — filaments created by a supernova explosion.

Located only about 160,000 light-years from us (eso1311) in the constellation of Dorado, the Large Magellanic Cloud is one of our closest galactic neighbours. It is actively forming new stars in regions that are so bright that some can even be seen from Earth with the naked eye, such as the Tarantula Nebula (eso1033). This new image, taken by ESO’s Very Large Telescope at the Paranal Observatory in Chile, explores an area called NGC 2035 (right), sometimes nicknamed the Dragon’s Head Nebula.

NGC 2035 is an HII region, or emission nebula, consisting of clouds of gas that glow due to the energetic radiation given off by young stars. This radiation strips electrons from atoms within the gas, which eventually recombine with other atoms and release light. Mixed in with the gas are dark clumps of dust that absorb rather than emit light, creating weaving lanes and dark shapes across the nebula.

This wide-field view captures several star formations regions in the constellation of Dorado. These glowing clouds of gas are located in the Large Magellanic Cloud, one of the Milky Way’s satellite galaxies. The bright region a little to the left of centre is NGC 2035.

This chart shows the southern constellation of Dorado (The Swordfish, sometimes referred to as a Dolphinfish). Most of the stars that can be seen in a dark sky with the unaided eye are marked. The location of the star formation region NGC 2035 in the Large Magellanic Cloud is indicated with a red circle. The nebula itself appears as a faint fuzzy patch in amateur telescopes, although the bright stars associated with this region can be very easily seen.

Zooming in on the star formation region NGC 2035
This zoom sequence starts with a broad view of the whole sky. We gradually close in on the Large Magellanic Cloud, a small neighbouring galaxy to our Milky Way. The final close-up shows a VLT image of NGC 2035, a star formation region that has an adjacent remnant created by a supernova explosion.
