NASA Spots Galaxies In Form Of Smiley

As NASA explains in its blog, amidst the twinkling lights, the telescope captured a formation of galaxies resembling a smiling face.

Here, nestled among a sea of galaxies, is a clear and unmistakable smiley face - two bright blobs suspended above a streak of light.

The play of light creates a huge shadow.

According to the USA space agency, the lower arc is created by gravitational lensing - an effect caused by light getting deformed due to the influence of a massive object on its path. "By analyzing the luminosity, size and formation rate of different stellar nurseries, scientists hope to learn more about the processes that can lead to the formation of a newborn star". Hubble Space Telescope's Wide Field Camera 3 is capable of seeing distant galaxies in unparalleled resolution, yet, high enough to locate and study regions where new stars are forming. Over time, these focal points become unstable, yielding to gravitational forces, until they become a kind of "seeds" that produce new stars.

Recently, using the data collected by Hubble and Kepler telescope, a team of researchers at the Columbia University found the evidence of the first moon outside the solar system. 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.

President Trump holds final midterm rally in Missouri
Trump paused his stump speech for roughly five minutes after being alerted to a medical emergency in the crowd of thousands. Cape Girardeau, MO - President Donald Trump will speak at a rally in Cape Girardeau, Missouri on Monday night, November 5.

It is named after famed astronomer Edwin Hubble who was born in Missouri in 1889.

Earlier, scientists have uncovered the mystery of black holes in the Universe.

Originally set to last 15 years, Hubble has now been in action making scientific discoveries for more than 28 years.

It orbits Earth at a speed of about 17,000 mph in low Earth orbit at about 340 miles in altitude.
