Carina Nebula (NGC 3372)

15.01.2004


Previously unseen details of a mysterious, complex structure within the Carina Nebula (NGC 3372), also called the ’Keyhole Nebula’, are revealed by this image obtained with the NASA/ESA Hubble Space Telescope.

The picture is a montage assembled from four different April 1999 telescope pointings with Hubble’s Wide Field Planetary Camera 2, which used six different colour filters.
The picture is dominated by a large, approximately circular feature, about 7 light-years across, which is part of the Keyhole Nebula, named in the 19th century by British astronomer Sir John Herschel. This region, about 8000 light-years from Earth, is located near to the famous explosive variable star Eta Carinae, which lies just outside the field of view toward the upper right.

The Carina Nebula also contains several other stars that are among the hottest and most massive known, each about 10 times as hot, and 100 times as massive, as our Sun.



The circular ’keyhole’ structure contains both bright filaments of hot gas and dark silhouetted clouds of cold molecules and dust, all of which are in rapid, chaotic motion. Two striking large, sharp-edged dust clouds are located near the bottom centre and upper-left edges of the image. These large dark clouds may eventually evaporate or, if there are sufficiently dense condensations within them, give birth to small star clusters.

The Carina Nebula, with an overall diameter of more than 200 light-years, is one of the outstanding features of the southern-hemisphere part of the Milky Way.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
