Hulk to Dr Who: NASA names new constellations after the stars of science fiction. Is your favorite there?

NASA scientists have developed a new set of 21 modern gamma-ray constellations and named them after fictional characters such as Hulk and Godzilla.

The constellations, constructed with visible sources using its gamma ray telescope, were designed to celebrate the completion of the 10-year operation of the Fermi Gamma Ray Telescope.

The new constellations include some characters from modern myths.

Among them are the Little Prince, Doctor Who's TARDIS, which distorts time, Godzilla and his heat ray, the U.S. with antimatter motor. Star Trek Enterprise: The Original Series & # 39; and Hulk, the product of a gamma ray experiment that went wrong.
"Developing these unofficial constellations was a fun way to celebrate a decade of Fermi achievements," said Julie McEnery, chief scientist of the Fermi project at NASA's Goddard Space Flight Center in the United States.

"In one way or another, all the ray constellations have a connection with the science of Fermi," said McEnery.

Since July 2008, the Fermi Large Area Telescope (LAT) has scanned the entire sky every day, mapping and measuring gamma-ray sources, the highest energy light in the universe.

The emission can come from pulsars, nova explosions, supernova explosions debris and giant gamma bubbles located in our own galaxy, supermbadive black holes and bursts. gamma – the most powerful explosions in the cosmos – in others.

"In 2015, the number of different sources mapped by the Fermi LAT had been multiplied by 3 – 10 times the number known before the mission," said Elizabeth Ferrara, head of the constellation project. .

"For the fi rst time, the number of known gamma ray sources was comparable to the number of bright stars, so we thought that a new set of constellations was a great way to get around." 39; illustrate this point, "said Ferrara.

The 21 gamma rays the constellations include famous sites – such as the recovered Swedish warship, Vasa, the Washington Monument and Mount Fuji in Japan – in countries contributing to the Fermi science.

The Others Scientists represent ideas or tools, from Schrodinger's cat to Albert Einstein, Radio Telescope and Black Widow Spider, named after a clbad of pulsars that evaporate their unhappy companions.

Researchers have developed an interactive web-based tool for presenting constellations with illustrations. by Aurore Simonnet, illustrator at Sonoma State University in Rohnert Park, California, and Fermi's gamma ray sky chart.
