Space is filled with bizarre signals that us Earthlings scramble to put meaning to. Researchers detected yet another mysterious signal that emanated from near a neutron star, and, for the first time, it’s infrared.
This signal, they found, was about 800 light-years away and was “extended,” meaning it was spread across a large stretch of space, unlike typical “point” signals from neutron stars that emit X-rays. Specifically, the signal stretched across 200 astronomical units (AU) of space, or 2.5 times the orbit of Pluto around the sun, according to a statement from Penn State. (One AU is the average distance from Earth to the sun — about 93 million miles, or 150 million kilometers.)
