NASA’s new space telescope has captured its first starlight and even taken a selfie of its giant, gold mirror. All 18 segments of the primary mirror on the James Webb Space Telescope seem to be working properly 1 1/2 months into the mission. The telescope’s first target was a bright star 258 light-years away in the constellation Ursa Major.

What

  1. Over the next few months, the hexagonal mirror segments each the size of a coffee table will be aligned and focused as one, allowing science observations to begin by the end of June.
  2. The $10 billion infrared observatory considered the successor to the aging Hubble Space Telescope will seek light from the first stars and galaxies that formed in the universe nearly 14 billion years ago.
  3. It will also examine the atmospheres of alien worlds for any possible signs of life.
  4. NASA did not detect the crippling flaw in Hubble’s mirror until after its 1990 launch; more than three years passed before spacewalking astronauts were able to correct the telescope’s blurry vision.
  5. While everything is looking good so far with Webb, engineers should be able to rule out any major mirror flaws by next month.
  6. Webb’s 21-foot (6.5-meter), gold-plated mirror is the largest ever launched into space. An infrared camera on the telescope snapped a picture of the mirror as one segment gazed upon the targeted star.
  7. Webb blasted off from South America in December and reached its designated perch 1 million miles (1.6 million kilometers) away last month.
