Gap – These signals are never noticed in the heart of the Milky Way. Thanks for this one Radiation telescopes Jideng Wang, who holds a PhD from the University of Sydney School of Physics, told ASKAP that the most important people in the world. Found. The characteristics of these waves are strange, report astronomers this Tuesday, October 12th Journal of Astronomy. They are particularly interested in the light they emit: the signal is turned on and then off approximately.

Other astronomical objects have different light, such as “supernovae”. Comets Or pulsars, a type of “dead” star that does not shine constantly. That’s why scientists initially thought it was dealing with this kind of celestial body, but “the signals coming from this new source don’t match,” says Jideng Wang.

The unknown signal was further observed by radio telescopes in Australia and South Africa. The signal has disappeared. Then he reappeared, but with a different demeanor: “The evidence disappeared overnight, while it lasted several weeks during our previous visit,” says Professor Murphy, one of the audience.

“Solve these mysteries” is a new super powerful telescope

The discrepancy between these signals can be categorized by what English speakers call the Galactic Center Radio Transients (GCRT). They are temporary signals activated at the center of the galaxy. David Kaplan, a professor at the University of Wisconsin-Milwaukee, one of the study’s supervisors, explains that there are “some parallels” with these mysterious objects. In the 2000s, there were three GRCTs Already determined.

In the years to come, scientists will be on the lookout for these signals to determine their origin. To help them, a new, powerful radio telescope, SKA, “R.Solve mysteries like this latest discovery and open up new areas of the universe, ”believes one of the authors of the study.
