New Massive Stars Spotted by Hubble

id = " Most of the biggest and brightest stars we've ever seen are packed in a cluster not even 170,000 light years from us. Now, Hubble has detected more massive stars in the group. Space Telescope has identified nine major stars with masses more than 100 times the mass of the Sun in the star cluster R136, which it is located in the Large Magellanic Cloud. Together, these nine stars are 30 million times brighter than the Sun. The results are published in the journal Monthly Notices of the Royal Astronomical Society, The team also found dozens of stars of 50 solar masses in the cluster, all packed in an area of ​​a few light years in diameter. were possible observations of the last update on Hubble in 2009, dramatically improved spatial resolution in the ultraviolet by repairing the Space Telescope Imaging Spectrograph (ITS). These bright and big stars are ultraviolet powers, so the Hubble has finally been able to solve individually. "The ability to distinguish ultraviolet light from a region so exceptionally busy into its component parts, the resolution of the signatures of individual stars, was only possible with the instruments on board the Hubble," said Paul Crowther, Sheffield University, lead author of the study, said in a statement. "Together with my colleagues, I would like to acknowledge the invaluable work done by astronauts during the last mission to repair Hubble: STIs are restored and put their lives at risk for the sake of the future science!" shown is the R136 cluster as seen in the ultraviolet. ESA / Hubble, NASA, KA Bostroem (STScI / UC Davis) R136 hosts the biggest, the brightest star ever observed, R136a, which has a mass of 265 suns and it is 8.7 million times the luminosity of our own star. This star and three more with a mass of 150 solar masses were discovered by Crowther and colleagues in 2010. The observations are amazing, but how these stellar giants form is still very mysterious. "These newly discovered stars are pushing the theoretical limits of what is possible in terms of the existence of a star," said Dr. Chris Pearson, an astronomer at the Space Campus RAL Harwell in the United Kingdom, in a comment sent to IFLScience. "Because of their size, they burn faster and brighter than our sun, which means that it hopes will significantly shorter life measured in millions rather than billions of years." This research is an important step forward in our understanding, but the team will continue to monitor this group in hopes of finding more clues about how these stars form. "Once again, our work shows that, despite being in orbit for more than 25 years, there are some areas of science that Hubble remains the only capable," Crowther said.
