Transcript

  • 1. Supernova Important Facts
  • 2. Earliest Recorded Supernova
    • The earliest recorded supernova, SN 185 , was viewed by Chinese astronomers in 185 AD.
  • 3. The brightest recorded supernova
    • The brightest recorded supernova was the SN 1006 , which was described in detail by Chinese and Arab astronomers .
  • 4. The widely observed supernovae
    • The widely observed supernova SN 1054 produced the Crab Nebula .
    • Supernovae SN 1572 and SN 1604 , the last to be observed with the naked eye in the Milky Way galaxy.
  • 5.
    • The brightest recorded supernova was the SN 1006 , which was described in detail by Chinese and Arab astronomers . The widely observed supernova SN 1054 produced the Crab Nebula . Supernovae SN 1572 and SN 1604 , the last to be observed with the naked eye in the Milky Way galaxy, had notable effects on the development of astronomy in Europe because they were used to argue against the Aristotelian idea that the universe beyond the Moon and planets was immutable. [11]
  • 6. Against belief
    • The sight of supernovae had notable effects on the development of astronomy in Europe because earlier people used believe the Aristotelian idea that the universe beyond the Moon and planets was immutable.
  • 7. Impact of telescopes
    • Since the development of the telescope , the field of supernova discovery has enlarged to other galaxies,
    • For example, in 1885 supernova Andromedae was observed in the Andromeda galaxy .
  • 8. How do supernovae help us?
    • Supernovae provide important information on cosmological distances
  • 9. How do we report the discovery of a supernova?
    • Supernova discoveries are reported to the International Astronomical Union 's Central Bureau for Astronomical Telegrams
  • 10. Naming
    • The first 26 supernovae of the year get designated with an upper case letter from A to Z. Afterward, pairs of lower-case letters are used, starting with aa, ab, and so on
  • 11. Naming of supernova
    • For example, the last supernova of 2005 was SN 2005nc, indicating that it was the 367th supernova found in 2005
  • 12. Naming of Supernova
    • In another approach, scientists started to name supernova based on the absorption lines of the elements present in the ejected material
