HD1: MOST DISTANT GALAXY EVER SEEN

Context

A galaxy known as HD1 may be the most distant object yet discovered by scientists. The brilliance of this galaxy could be attributed to a vast black hole at its centre or the formation of large primordial stars.

Key Points

  • Fabio Pacucci and his colleagues at the Harvard-Smithsonian Center for Astrophysics in Massachusetts identified the galaxy HD1.
  • They went through massive volumes of publicly available data sets from multiple powerful telescopes.
  • After sorting through the data, they spotted HD1 using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.

What do these observations indicate?

  • These scans revealed that the newly discovered galaxy is around 33.4 billion light-years away, more than a billion light-years farther than the previously found most distant object, a galaxy known as GN-z11. 
  • The universe is approximately 13.8 billion years old because it is constantly expanding, yet the distance between this galaxy and the rest of the universe is significantly greater. 
  • This recently discovered galaxy is incredibly brilliant in ultraviolet wavelengths, implying that whatever is causing it is highly hot.

Reasons for this galaxy's radiance

  • There are two possibilities for why it shines so brightly: it is undergoing tremendous star creation compared to the galaxy's modest size, or it contains an active supermassive black hole.
