New advanced NASA image reveals flowing ‘river of stars’

The Hubble Telescope has provided an incredible image of a river of star formation as four galaxies interact.

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

On May 17, NASA revealed the new image in which scientists refer to the depicted phenomenon as a river of star formation.

“This newly revised NASA Hubble Space Telescope image of the Hickson Compact Group 31 (HCG31) galaxies highlights streams of star-formation as four dwarf galaxies interact,” the agency wrote.

In the image, to the top right of center is a distorted cluster of bright, blue and white stars, NASA reports.

This region is called NGC 1741 and is actually two dwarf galaxies colliding.

To his right, the cigar-sized dwarf galaxy is joined by a thin, blue stream of stars that connects all three.

A fourth galaxy sits at the bottom left of the center of the picture.

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

The bright object in the middle of the image is a star located between Earth and HCG 31, NASA wrote.

Dwarf galaxy encounters are typically observed billions of light-years away, meaning they occurred billions of years ago.

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

This newly-revised image sheds light on the star-forming regions that have popped up as galaxies interact, dubbed the “gravitational dance of the Quartet” by NASA.

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

Hubble’s Impressive Imagery

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

Also in May, the telescope captured an astonishing image of A spiral galaxy with a ‘grand design’.

The stunning photo was taken via its Wide Field Camera 3 (WFC3) and shows the galaxy, named Messier 99 (or M99), in ultraviolet and optical light.

In the photo, the galaxy’s dazzling arms occupy most of the frame as they glow in many shades of purple, blue and deep red.

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

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.

The scientists noted that this image is important because it helped them study two separate celestial phenomena.

Astronomers were able to detect a vanishing cosmic explosion whose brightness level is somewhere between a nova and a supernova.

Nova in binary systems are caused by interactions between white dwarfs and massive stars, while supernovae involve the horrific violent deaths of massive stars.

The eruption was first observed in 2010 and is considered a big mystery by scientists, who are unsure of its cause.

One such explanation proposed by the researchers includes that the increased brightness of the star may be due to “a giant planet sinking into its parent star,” NASA said.

Second, the researchers were able to use the image to trace the connection between a young star and the gas clouds that rise from it.
