Astronomers Have Detected A Mysterious Signal Coming From Empty Space. Nobody Knows What It Is

In the southern constellation of Fornax lies a tiny patch of sky just like any other. Your eyes may have brushed past it a hundred times without a thought.

Yet this otherwise unremarkable speck of the cosmos is among the most well-cataloged in the sky. The Hubble Space Telescope stared at it for more than 270 hours to obtain its famous Ultra Deep Field (HUDF) – and contained therein are nearly 10,000 galaxies extending billions of light-years into the Universe.

When the James Webb Space Telescope (JWST) launched, it was only natural that its golden mirrors would turn to the same region of space, using its vastly more sensitive infrared capabilities to find what Hubble may have missed.
