JAMES WEBB SPACE TELESCOPE

Feb. 13, 2022

NASA’s new space telescope has captured its first starlight and even taken a selfie of its giant, gold mirror.

About:

  • All 18 segments of the primary mirror on the James Webb Space Telescope seem to be working properly a month-and-half into the mission.

  • The telescope's first target was a bright star 258 light years away in the constellation Ursa Major.

  • Over the next few months, the hexagonal mirror segments will be aligned and focused as one, allowing science observations to begin by the end of June.

  • The $10 billion infrared observatory – considered the successor to the ageing Hubble Space Telescope – will seek light from the first stars and galaxies that formed in the universe nearly 14 billion years ago.

  • It will also examine the atmospheres of alien worlds for any possible signs of life.

  • Webb’s 6.5-metre, gold-plated mirror is the largest ever launched into space.

  • Webb blasted off from South America in December and reached its designated perch 1.6 million kilometres away last month.
