Hubble discovers one of largest star located in neighbourhood of Milky Way

NASA/ESA joint venture Hubble Space Telescope has discovered a young super star cluster located 15,000 light years away. Named as Westerlund 1, it has very large stars and contains one of the largest stars ever discovered.

Scientists scanned the image beamed back by the HST and found the presence of an enormous star named Westerlund 1-26. Scientists classify stars according to their spectral type, surface temperature, and luminosity. However, the monster star is a red supergiant (although sometimes classified as a hypergiant) with a radius over 1,500 times that of our sun. If Westerlund 1-26 were placed where our sun is in our solar system, it would extend out beyond the orbit of Jupiter.

Most of Westerlund 1’s stars are thought to have formed in the same burst of activity, meaning that they have similar ages and compositions. The cluster is relatively young in astronomical terms —at around three million years old it is a baby compared to our own sun, which is some 4.6 billion years old.

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington, D.C.

The Hubble space telescope was launched in 1990 and since then it is the largest telescope in space. HST has helped scientists in exploring the deepest corners of the universe and has beamed back millions of stunning shots in its entire career. However, HST will be replaced by the James Webb Telescope in 2018 as it has thrice larger lens when compared to HST.
