A colossal hourglass-shaped structure has been spotted in the middle of the Milky Way by the MeerKAT telescope at the South African Radio Astronomy Observatory.
Researchers examining the almost-symmetrical pair of enormous radio-emitting bubbles that tower above and below the central plane of our galaxy (marked by the series of bright features running horizontally through the image) think they were formed by a phenomenally energetic burst that erupted near Sagittarius A*, the supermassive black hole at the centre of our Galaxy, millions of years ago.
“These enormous bubbles have, until now, been hidden by the glare of extremely bright radio emissions from the centre of the Galaxy,” says Dr Fernando Camilo of SARAO.
