From IAC: “Jellyfish by Cesar Blanco”

In the picture above, we have an excellent work of Cesar Blanco Gonzalez, from deep sky show IC 443, which is a supernova remnant located in the constellation of Gemini. Is believed to have originated from a supernova that exploded in a period of between 3.000 and 30.000 years ago, and that the core of the star parent responsible for this event has formed the neutron star cxou j061705. 3 + 222.127. it is a subject very studied, due to their interaction with other molecular clouds. IC 443 has an angular diameter of 50 Arc minutes, at a distance of 5.000 Light-years is equivalent to a real size of about 70 Light-years away. The Nebula, in both the visible as in radio waves, is shaped like a shell, which consists of two halves with different radio, and in the center, a third layer nebula, originally attributed to IC 443, is now recognised as the Supernova Remnant oldest called G189. 6 + 3.3. through observations with the observatory chandra x-Ray and the xmm-Newton, he has identified a pulsar near the southern bypass.

IC 443 is located in the direction of the galactic plane. Many objects are found in this area of the sky, as the region hii s249, and several young stars. The Nebula thrives in an environment rich and complex, with strong influence over its morphology; comments in long wavelengths conducted in this area of sky shows the presence of mysterious gradients and different shapes of the clouds. We know that massive stars have a relatively short life (about 30 million years ago) and end their lives when they are still within the cloud parent; the most massive stars (Stars of the class or) illuminate the environment with his mighty wind Stellar.

The Instituto de Astrofísica de Canarias(IAC) is an international research centre in Spain which comprises:

The Instituto de Astrofísica, the headquarters, which is in La Laguna (Tenerife).
The Centro de Astrofísica en La Palma (CALP)
The Observatorio del Teide (OT), in Izaña (Tenerife).
The Observatorio del Roque de los Muchachos (ORM), in Garafía (La Palma).

These centres, with all the facilities they bring together, make up the European Northern Observatory(ENO).

The IAC is constituted administratively as a Public Consortium, created by statute in 1982, with involvement from the Spanish Government, the Government of the Canary Islands, the University of La Laguna and Spain’s Science Research Council (CSIC).

The International Scientific Committee (CCI) manages participation in the observatories by institutions from other countries. A Time Allocation Committee (CAT) allocates the observing time reserved for Spain at the telescopes in the IAC’s observatories.

The exceptional quality of the sky over the Canaries for astronomical observations is protected by law. The IAC’s Sky Quality Protection Office (OTPC) regulates the application of the law and its Sky Quality Group continuously monitors the parameters that define observing quality at the IAC Observatories.

The IAC’s research programme includes astrophysical research and technological development projects.

The IAC is also involved in researcher training, university teachingand outreachactivities.

The IAC has devoted much energy to developing technology for the design and construction of a large 10.4 metre diameter telescope, the ( Gran Telescopio CANARIAS, GTC), which is sited at the Observatorio del Roque de los Muchachos.
