NASA Spots Galaxies In Form Of Smiley

NASA has released the photo of distant galaxies seemingly smiling back to the observatory. WFC3 is able to view distant galaxies at an unprecedented resolution - high enough to locate and study regions of star formation within them.

On Saturday, it posted an image on its Instagram handle that showed two yellow orbs above an arc of light - painting a smiley face in space.

The sweeping arc of light that makes up the mouth appears to be pulled out of shape due to the strong gravitational forces distorting its light.

But the "smile" is actually evidence of a phenomenon known as "gravitational lensing" - wherelight is "bent" by the gravity of massive objects in the foreground on its way towards us. Because of its position, the space telescope can see and capture the effect, which cannot be detected by ground-based observatories.

A cluster of galaxies that look like a smiling face has been spotted by NASA's Hubble Space Telescope. The lifetime of the young stars is very small in astronomical terms - just a few million years.

NASA hopes to analyze the luminosity, the size, and the rate of formation of stars in different stellar nurseries from various points in time throughout the universe.

Hubble Space Telescope returned to normal operations on October 26 after successfully recovering a backup gyroscope that had replaced a failed one three weeks earlier. For two weeks, the space observatory had been placed into safe mode as engineers figured out their next step of action.

With the assistance of the powerful Hubble telescope, the Terrans got a unusual space news.
