NASA’s newly enhanced image shows a flowing “river of stars” as four galaxies interact

THE Hubble telescope has provided an incredible image of a flux of star formation as four galaxies closely interact.

The newly revised image, originally released in 2010, shows a rare interaction between the celestial bodies in the Hickson Compact Group 31.

NASA unveiled the new image on May 17, with scientists dubbing the phenomenon pictured a flux of star formation.

“This newly revised NASA Hubble Space Telescope Hickson Compact Group 31 (HCG 31) image of galaxies highlights streams of star formation as four dwarf galaxies interact,” the agency wrote.

There is a distorted cluster of bright blue and white stars in the upper-right center of the image, NASA reports.

This area is called NGC 1741, and it’s actually two dwarf galaxies colliding.

Attached to its right is a cigar-shaped dwarf galaxy with a thin stream of blue stars connecting the trio.

A fourth galaxy sits in the lower left center of the photo.

A stream of young blue stars points directly at it, tying all four together in the relatively small space.

The bright object at the center of the photo is a star sandwiched between Earth and HCG 31, NASA wrote.

Encounters with dwarf galaxies can usually be seen billions of light-years away, meaning they happened billions of years ago.

However, HCG 31 is located about 166 million light-years from Earth, which is relatively close by cosmic standards.

This newly revised image highlights star-forming regions formed by the merging of galaxies in what NASA calls “the gravitational dance of the quartet.”

“The color blue represents visible blue light and shows young, hot, blue stars, while the color red represents near-infrared light,” scientists wrote.

HUBBLES IMPRESSIVE PICTURES

The Hubble Telescope has been helping scientists explore universes for over three decades.

Also in May, the telescope captured an impressive image of a spiral galaxy with “magnificent design”.

Taken with the Wide Field Camera 3 (WFC3), the stunning photo shows the galaxy named Messier 99 (or M99) in ultraviolet and optical light.

In the photo, the galaxy’s dazzling arms take up most of the frame as they shine in multiple shades of purple, blue, and crimson.

M99 is located about 55 million light-years from Earth in the constellation of Coma Berenices.

It is considered a so-called grand design galaxy because of its “well-defined, prominent spiral arms,” ​​the European Space Agency said in a statement.

Scientists determined that this image is significant because it helped them study two different astronomical phenomena.

Astronomers have been able to further study a fading cosmic explosion whose luminosity falls somewhere between novae and supernovae.

Novas are caused by the interactions between white dwarfs and larger stars in binary star systems, while supernovas involve the catastrophically violent deaths of massive stars.

The explosion was first observed in 2010 and is considered a major mystery by scientists unsure of what caused it.

One such explanation proposed by researchers includes that the star’s increased brightness could have been caused by “a giant planet plunging into its parent star,” NASA said.

Second, the researchers were able to use the image to study the connection between a young star and the gas clouds from which it grows.
