One of the brightest stars °
Peony one of the brightest stars in the center of the galaxy Scientists estimate the Peony star, located in the center of the galaxy, with a mass 150 times greater than the sun and a brightness of 3.2 million suns. Will this and other stars like Eta Carinae force us to revolve around them? How old would that orbit Earth? Which of these two massive stars explode first?
The discovery of the new star was carried out by the Spitzer Space Telescope team with the help of the European Southern Observatory, located in Chile.

Peony "is a fascinating creature. Seems to be the second brightest star in our galaxy that we know and is located deep in the center of the galaxy, "said Lidia Oskinova, an astronomer at the University of Potsdam, Germany.
According to the models of stellar evolution, astronomers think Eta Carinae similar in characteristics to the newly discovered Peony, will end his days in a cataclysmic supernova explosion. There
accuracy of when this will happen, but it could be within the next thousand years, a brief period in the life cycle of any star. Is may even have the good fortune to observe this phenomenon during the period of our lives such as occurred on May 1, 1006 when the sky watchers saw the agony of the supernova SN 1006, which exploded in the Milky ago 8,000 years.
The Citizen What is Spitzer Telescope Spitzer Space Telescope (formerly SIRTF, for its acronym in English, or the Space Infrared Telescope Facility) is a space observatory cryogenically cooled infrared observatory capable of studying objects ranging from our Solar System to more distant regions of the Universe. Spitzer is the final element of the Program of NASA's Great Observatories, and a key from the standpoint of scientific and technical program of the new Astronomical Search for Origins. Spitzer observatory consists of a telescope of 0.85 meters with three cryogenically cooled science instruments capable of taking images and spectra from 3 to 180 microns. With its high sensitivity, whole large format detectors, high efficiency and long life observational cryogenic Spitzer provides unprecedented observational capabilities. The observatory was launched in August 2003 and current estimates suggest a lifetime of about 5 years.
