NASA finds the ‘Lost Galaxy’

Recently, the Hubble Space Telescope of NASA captured the images of the NGC 4535 which is also known as the “Lost Galaxy”.  The image highlights that the young and hot stars that hang out are the bright blue spots. On the other hand, older and cooler stars are highlighted by the bright shades nearer to the center.

Background

An amateur astronomer Leland S. Copeland fixed his telescope lens on a distant galaxy in the Virgo constellation first in 1950s. He then withnessed an eerie spiral that was shrouded in dust. He named the spiral as “The Lost Galaxy”.

About the Lost Galaxy

  • It is also known as NGC 4535.
  • The galaxy is one of the largest of some 2,000 galaxies in the Virgo Cluster.
  • The galaxy is located about 50 million light-years from Earth.
  • It is a barred spiral galaxy that means a vast swirl of stars having a distinct bar structure at its center.
  • The galaxy gives the yellowish glow at its central bulge. The yellowish glow suggests the way to the oldest and coldest retinue of stars in the Lost Galaxy.
  • The Galaxy was discovered in 1785 by William Herschel who found the planet Uranus.
  • The galaxy was termed as the Lost Galaxy by Copeland because then he had a glimpse of NGC 4535 using his small yard lenses.

Spiral galaxy

The concept of the Spiral Galaxy was first described by Edwin Hubble in 1936 The Spiral galaxy is the most common type of galaxy in universe. It has a spiral shape because of long arm full of stars. The galaxy extends from the center into the galactic disc. The galaxy comprises of a flat, rotating disk containing the stars, gas and dust, and a central concentration of stars called as bulge. It is surrounded by a much fainter halo of stars.
