Galaxy Messier 87 (M87)

Galaxy Messier 87 (M87):

Scientists studying the galaxy Messier 87 (M87) – which surrounds the only black hole to have been imaged so far – have come up with a theoretical model of the jets of material emanating from M87.

  • The calculated images published in Nature Astronomy resemble closely what is observed, and help confirm Einstein’s theory of relativity.
  • Messier 87 (also known as Virgo A or NGC 4486, generally abbreviated to M87) is a supergiant elliptical galaxy with several trillion stars in the constellation Virgo.
  • One of the most massive galaxies in the local universe, it has a large population of globular clusters—about 15,000 compared with the 150–200 orbiting the Milky Way and a jet of energetic plasma that originates at the core and extends at least 1,500 parsecs (4,900 light-years), traveling at a relativistic speed.
  • It is one of the brightest radio sources in the sky and a popular target for both amateur and professional astronomers.
