Today, astronomers announced they have discovered eight galaxies so bright, there isn’t even a scientific word to describe them yet. When an infrared galaxy is analyzed and rated to consist of 1 trillion solar luminosities, it’s called “ultra-luminous.” When a galaxy is at 10 trillion solar luminosities, it is “hyper-luminous.” But these galaxies are so bright they are measured at 100 trillion solar luminosities. In the world of astronomy, this is unheard of.

A team from the University of Massachusetts Amherst, led by astronomy professor Min Yun and senior undergraduate Kevin Harrington, has taken to calling these galaxies “outrageously luminous” — not an official scientific term but super apt regardless — in their report in the Monthly Notices of the Royal Astronomical Society. The team estimates that these galaxies are about 10 billion years old and formed an estimated four billion years after the Big Bang.

“The galaxies we found were not predicted by theory to exist; they’re too big and too bright,” Yun says in a press release.

To search for these massive star clusters, the team used a 50-meter diameter Large Millimeter Telescope, which is is located at the summit of a 15,000 extinct volcano in Puebla, Mexico. The telescope is considered the largest, most sensitive single-aperture for studying star formation in existence. They also collaborated with NASA and the ESA to use the Planck satellite, which can detect the glow of the Big Bang and cosmic microwave background.

The telescope is jointly operated by Mexico's Instituto Nacional de Astrofísica, Óptica y Electrónica.

The researchers theorize that one reason analyses have revealed these galaxies to be so bright is because they were created by an “amazingly high” rate of star formation. While the Milky Way is thought to produce only a few solar masses of stars per year, these galaxies seem to have formed one star every hour.

Gravitational lensing, a phenomenon that happens when magnified light passes by massive objects, is also thought to be why these look so bright. In reality, these galaxies look to Earth-bound astronomers probably 10 times brighter than they actually are. Regardless, they are brighter than anything astronomers have seen before.

Besides looking really cool, the team behind this research hopes that by studying these eight galaxies, they can gain a better understanding of how matter collects and forms a galaxy. This, in turn, could explain some of the mystery of what the Universe was like in its earliest years.

“Knowing that they really do exist and how much they have grown in the first four billion years since the Big Bang helps us estimate how much material was there for them to work with,” says Yun. “They suggest that this process is more complex than many people thought.”

Daft Punk must have invaded the ears of NASA staff when planning for the Space Launch System rocket, taking, “Harder, Better, Faster, Stronger” to heart.

The SLS has been constructed for the first mission of (hopefully) many to chase ambitions of deep space travel, and once completed, it will claim the title as the most powerful rocket in the world. In a video released Monday, NASA explains how assembling the pieces constructed across the United States presents engineers with a dizzying challenge.

There are a lot of reasons to be excited about the recent discovery of an Earth-like, frozen planet orbiting one of our neighboring stars. For one, it represents the culmination of years of searching for exoplanets, and two, as one scientist involved in the search tells Inverse, it may open the floodgate to finding more potentially habitable planets in the future.

It’s that time of year where the pressure’s on to find super cool gifts for the people you love. Instead of scrambling around this year for last-minute gifts, why not head over to one of our favorite lifestyle product sites, Huckberry, and take a look at the Levimoon, which you’ve probably guessed by now is a levitating moon.

Jason’s bloodstained hockey mask hangs from the office door of Dr. Anthony Tobia, an associate professor of psychiatry at Rutgers University’s Robert Wood Johnson Medical School. It’s a chilling introduction to his October “didactics,” classes in which he and his residents watch a horror movie each night of the month through the spooky lens of psychiatry. Today, he’s showing his students a classic: the original Nightmare on Elm Street.
