This photograph offered by NASA exhibits a “selfie” created utilizing a specialised pupil imaging lens within the NIRCam instrument that was designed to take pictures of the first mirror segments as a substitute of pictures of house.
Highlights
- NASA’s new house telescope captured its 1st starlight and brought selfie of its large, gold mirror
- All 18 segments of main mirror on James Webb Area Telescope appear to be working correctly
- The telescope’s first goal was a shiny star 258 light-years away within the constellation Ursa Main
NASA’s new house telescope has captured its first starlight and even taken a selfie of its large, gold mirror.
All 18 segments of the first mirror on the James Webb Area Telescope appear to be working correctly 1 1/2 months into the mission, officers stated on Friday.
The telescope’s first goal was a shiny star 258 light-years away within the constellation Ursa Main.
“That was only a actual wow second,” stated Marshall Perrin of the Area Telescope Science Institute in Baltimore.

Over the subsequent few months, the hexagonal mirror segments- every the scale of a espresso table- will likely be aligned and centered as one, permitting science observations to start by the top of June.
The $10 billion infrared observatory- thought-about the successor to the getting old Hubble Area Telescope- will search mild from the primary stars and galaxies that shaped within the universe practically 14 billion years in the past. It should additionally look at the atmospheres of alien worlds for any potential indicators of life.
NASA didn’t detect the crippling flaw in Hubble’s mirror till after its 1990 launch; greater than three years handed earlier than spacewalking astronauts have been in a position to appropriate the telescope’s blurry imaginative and prescient.
Whereas every little thing is trying good up to now with Webb, engineers ought to have the ability to rule out any main mirror flaws by subsequent month, Feinberg stated.
Webb’s 21-foot (6.5-meter), gold-plated mirror is the biggest ever launched into house. An infrared digicam on the telescope snapped an image of the mirror as one section gazed upon the focused star.
“Just about the response was ‘Holy Cow!’,” Feinberg stated.
NASA launched the selfie, together with a mosaic of starlight from every of the mirror segments. The 18 factors of starlight resemble shiny fireflies flitting in opposition to a black evening sky.
After 20 years with the venture, “it’s simply unbelievably satisfying” to see every little thing working so properly up to now, stated the College of Arizona’s Marcia Rieke, principal scientist for the infrared digicam.
Webb blasted off from South America in December and reached its designated perch 1 million miles (1.6 million kilometers) away final month.
