NASA explained that using an unprecedented resolution of the Hubble's camera it was able to locate and study regions of the star formation. In an image posted on the NASA web page, two yellow orbits can be seen over an arc of light painting a smiling face in the middle of an ocean of stars.

NASA says the "mouth" is created by a trick of the light.

By analysing the luminosity, size and formation rate of young stars in images like these, researchers at NASA hope to better understand how stars are formed in the cold and dusty corners of the Universe.

'The lower, arc-shaped galaxy has the characteristic shape of a galaxy that has been gravitationally lensed - its light has passed near a massive object en route to us, causing it to become distorted and stretched out of shape, ' it said. For a long time are the nurseries of stars are unstable, until it becomes a kind of "seed", which creates new solar lights.

Galaxy is located at a distance of 100 million light years from Earth. It's important to study stellar formation within different galaxies to gain a richer context, which is why Hubble had its gaze fixed on a galaxy cluster.

With the assistance of the powerful Hubble telescope, the Terrans got a unusual space news. The device got its name from the famous American astronomer Edwin Hubble.

The Hubble, behind iconic images such as Pillars of Creation has watched the skies for 28 years, having launched in 1990.

Hubble's primary mirror is 2.4 meters (7 feet, 10.5 inches) across and in total is 13.3 meters (43.5 feet) long - the length of a large school bus.
