A stellar structure known as the ‘Hand of God’ is a nebula of energy and particles blown by a pulsar left behind after a star exploded in our Milky Way Galaxy.

Otherwise known as MSH 15-52 or G320.4-1.2, the object is located some 17,000 light-years away in the constellation of Circinus.

In a paper in the Astrophysical Journal Letters, they report how quickly the supernova remnant associated with the hand is moving, as it strikes a cloud of gas called RCW 89; the inner edge of this cloud forms a gas wall located about 35 light-years from the center of the explosion.

In the new study, Dr. Kazimierz Borkowski and his colleagues from North Carolina State University used the data from NASA’s Chandra X-ray Observatory from 2004 and 2008, and then a combined image from observations taken in late 2017 and early 2018.

“The rectangle highlights the motion of the explosion’s blast wave, which is located near one of the fingertips. This feature is moving at almost 14.5 million km per hour (9 million mph),” the astronomers explained.

“The fixed squares enclose clumps of magnesium and neon that likely formed in the star before it exploded and shot into space once the star blew up.”

“Some of this explosion debris is moving at even faster speeds of more than 17.7 million km per hour (11 million mph).”

“The 2018 image shows the fingers in blue and green and the clumps of magnesium and neon in red and yellow.”

Cosmic Hand Hitting a Wall

The "hand" is actually a nebula of energy and particles generating by a pulsar.

As a blast wave from an exploded star moves through space, it is running into a cloud of gas.

Since the explosion, the supernova remnant — made of debris from the shattered star, plus the explosion's blast wave — and the X-ray nebula, have been changing as they expand outward into space.

Notably, the supernova remnant and X-ray nebula now resemble the shape of fingers and a palm.
