Astronomers were shocked by the explosion of historic stars!

The bright stellar explosion explosion is known from our galaxy, as a typical supernova explosions released by the energy, you can leave the corpse of a star almost the same. However, in this case, a binary system still exists and plays an important role in a major explosion.

Armin left to determine the extent of the echo of Eta Carina, and the extent of the explosion surrounding it, in the last seven years by the Space Arizona team's Space Telescope Science Institute led by Nathan Smith and astronomers such extreme stellar celebrated Eta Carina.

In light of the bright light, when the event can be seen from clouds of dust, the light will be resonated, as dust like a distant mirror, the light will reach our direction. Like an audio echo, due to the limited speed of light, the incoming signal of reflected light is delayed after the original incident. In the case of Eta Carina, the brightest event star, "big explosion" is also known in the mid-19th century, during a major outbreak, it expelled a lot of quality. These delay signal resonance light so that light astronomers can be used modern telescopes and volcanic eruption decoding tools, even though the original mid-19th century saw erupted from the earth. It was sometime before the invention of modern equipment such as astronomical spectrometer.

Smith said, "Light reverberance is the next best option for time travel." "That's why they have such a beautiful echo that we are witnessing the first opportunity, the explosion of the explosion, to uncover the rare 170 years of mysteries, but we are giving the use of our modern telescope and the camera. Information about the residual nebula of 170 years can be expelled. This is a huge stellar explosion, from a very rare monster star, since our Milky Way is not so.

Large volcanic eruptions temporarily Eta Carina, in our second night sky, visible from bright stars, each star's energy in the galaxy is doing more than the energy production, then gradually with star visibility for naked eyes Disappear Explosive material (about 10 times the Sun's mass) also creates a bright cloud of flashing gas called Homunculus. This dumbbell-shaped residue can be seen from the vast star formation region. In the southern hemisphere a small amateur telescope and Earth's equatorial regions can also see explosion residues, but to see the best images taken by the Hubble Space Telescope.

Magellan telescope 8 meter Gemini south telescope, Kero Tololo Inter-American Observatory 4 meter Blanco telescope and Las Campanas Observatory and exploration explosion detailing the history of these on-the-flight echoes of the instrument used decoding the instrument used by the team. Rest representation "Gemini Spectroscopy At unprecedented speed, we help in determining this gas, which is observed in the speed between about 10,000 to 20,000 kilometers per second, is in motion." The research team, Gemini Observatory and Blanco Telescope are supported by the National Science Foundation (NSF).

"We saw these real high speeds in the supernova explosion, and the star was erased." Smith told. However, in this case, the star survived and explained that the researchers entered into new areas. Smith said, "Star of energy should be put in a lot of time as a lot of time." Smith and his colleagues say, 20 times faster than a typical big stars, according to Eta Carina's expulsion of wind speed, therefore, the help of two companion stars can explain extreme outflow.

Researchers suggest that the most direct way to interpret volcanic eruption and stellar system surrounding a variety of facts is a dramatic event in which two stars are in talks between three stars, including three stars, merged into a monster star. If this is the current dual system should be started as a triple system, one of the stars of the galaxy swallowed its brother.

"Understanding the dynamics of the biggest stars in the galaxy and surrounding environment is one of the toughest areas of astronomy," says Gemini Chief Financing Agency NSF Richard Green, director of astronomical science. "Compared with our stars like the sun, the life of a very large star is very short, but occupied is a planet statistically impossible in a major evolutionary step. This is the reason that it is so important that the cases of Eta Carina, And why NSF supports this research. "

In Chile a mission head of the Aura Observatory, Chris Smith and a part of the research team added a historical perspective. "I'm very excited, we can see a little echo from the events that John Herschel discovered in the mid-19th century.
