From Manu Garcia: “30 Doradus, the Tarantula Nebula”


Manu Garcia, a friend from IAC.

The universe around us.
Astronomy, everything you wanted to know about our local universe and never dared to ask.

Beware arachnophobia, Hubble caught near the tarantula.

Tarantula Nebula.

Hubble has taken this impressive foreground of the Tarantula nebula . This star – forming region of ionized hydrogen gas is in the Large Magellanic Cloud (LMC), a small neighboring galaxy to the Milky Way. It is home to many extreme conditions, including supernova remnants and heaviest star ever found. The Tarantula Nebula is the brightest nebula of its kind in the local Universe.

Caught in the spider web.
The Hubble Space Telescope NASA / ESA has produced an outstanding image of the famous Tarantula Nebula , a cloud of gas and dust star in our neighboring galaxy, the Large Magellanic Cloud. In this picture, we see a close up of the central region of the Tarantula, glowing with ionised gas and young stars.

The dusty arms of the Tarantula Nebula was originally thought to resemble spindly spider legs, giving the nebula its unusual name tarantula. Part of the nebula visible in this image from the Advanced Camera for Hubble images is criss – crossed with tendrils of dust and gas agitated by recent supernovae. These residues include NGC 2060 supernova, visible above and left of the center of the image containing the known press brighter.

Tarantula bite goes beyond NGC 2060. Near the edge of the nebula, outside the frame, below and to the right are the remains of the supernova SN 1987a, the closest supernova to Earth seen from the invention of telescopes in the seventeenth century. Hubble and other telescopes have been returning to spy on this stellar explosion regularly since it exploded in 1987, and each subsequent visit shows an expansion wave that ignites the gas around the star, creating a pearl necklace of bright pockets of gas around remains of the star. SN 1987a is visible in wide field images Nebula, as taken by ESO MPG / 2.2m.

Together with dying stars, the Tarantula Nebula is full of young stars that have recently formed from the hydrogen supply by the nebula. These newly born stars shine with intense ultraviolet light ionizes the gas, causing it to glow red. The light is so intense that, although it is about 170,000 light – years away in the constellation Dorado, and outside the Milky Way, the Tarantula Nebula is visible without a telescope on a dark night observers linked to Earth . This nebula might be far away, but it is the brightest of its kind astronomers have observed in the local Universe example.

A set of compact and extremely bright stars called RMC 136 is above and to the left of this view, providing much of the power radiation multicolored glow. Until recently, astronomers debated whether the source of the intense light was a cluster tightly bound stars, or perhaps an unknown type of superstar thousands of times bigger than the sun. It is only in the last 20 years, with fine detail revealed by Hubble and the latest generation of ground-based telescopes, astronomers have been able to prove conclusively that it is, indeed, a star cluster.

But even if the Tarantula Nebula does not contain this hypothetical super-star, still gets some extreme phenomena, making it a popular target for telescopes. Within the group of bright stars is the RMC 136a1 star, who recently was found to be the heaviest ever discovered: the mass of the star when he was born was about 300 times the Sun This heavyweight challenges theories of astronomers. on the formation of stars, breaking the upper limit they thought existed in the stellar mass.

The Hubble Space Telescope is a project of international cooperation between ESA and NASA.
