Fresh off the heels of our most detailed ever look at the mysterious interstellar comet 3I/ATLAS, the astronomy world is once again abuzz with excitement today after ANU researchers at the Mount Stromlo Observatory captured a mysterious and incredibly energetic being entering Australian airspace.

It was business as usual for Associate Professor Brad Tucker, who was manning the state-of-the-art, high resolution Infrared All-Sky Camera, which captures images of the night sky every 30 seconds, at the observatory where he was scanning for supernovas and comets.

It was at that moment he spotted something unusual – the faint red glow of something, or someone, darting through the Canberra sky at the speed of light.

Brad is advising all kids to get to bed before Santa’s imminent arrival.

Merry Christmas and a Happy New Year to all!
