Astronomers have Watch Woman Living in A Motel Room Onlinespotted a pair of exotic features believed to be the aftermath of a colossal cosmic smackdown — not between two galaxies, but two groupsof galaxies.
These glowing arcs of radio energy are known as "radio relics," faint clouds resulting from powerful shockwaves surging through hot gas that fills the spaceamid a galaxy cluster.
The cluster, PSZ2 G181.06+48.47, is some 963 million light-yearsfrom Earth, but its image is less forgettable than its name. Using the Giant Metrewave Radio Telescope in India and the Very Large Array in New Mexico, a team of researchers spotted the arcs flanking the cluster like giant parentheses. The distance between the punctuation is an estimated 11 million light-years — about 100 times the span of the Milky Way.
That makes their separation a record holder — "the largest known to date," according to a paperpublished on the discovery in The Astrophysical Journal.

These groups and clusters, containing hundreds to thousands of galactic neighborhoods, serve as building blocks for the larger structures of the universe. Clusters are also composed of scorching gas that reaches millions of degrees as well as dark matter, an invisible material that scientists don't yet fully understand.
The team, led by Kamlesh Rajpurohit, an astronomer at the Harvard & Smithsonian Center for Astrophysics, thinks the newfound radio relics formed when shock fronts sped through space following two clusters wrecking. These waves can force particles to shine in radio light.
Though these two come as a pair, they're not identical twins. The researchers describe the northernmost glow as brighter and polarized, meaning its light is moving in the same direction. Its companion to the south has a stranger ghostly shape and an energy pattern that may mean it was caused by a more powerful shockwave.

In the past, astronomers have dubbed clusters fun nicknames based on the shapes of their relics, such as the Toothbrush Cluster. Perhaps in the future this one will leave behind its numerical moniker for something a bit snazzier, like the Eyebrows Cluster or the Air Quotes Cluster. Until that time, you can call it Planck cluster G181+48 for short, Rajpurohit said.
Scientists discovered one other curiosity between the relics: a faint glow at the center of the cluster. This could be a so-called "radio halo," another kind of radio source that emerges when churning gas and particles create turbulence after a violent cosmic crash.
Astronomers have previously detected less than 30 such clusters with relic pairs. But the upcoming Square Kilometre Array being built in South Africa and Australia could be a "game changer," according to the paper's authors.
"There could potentially be many more awaiting discovery in the era of large radio surveys," they said.
