A new image from the European Southern Observatory captures a Cosmic Bat tucked away in one of the darkest corners of the Orion constellation.
The Cosmic Bat, formally known as NGC 1788, is a dusty nebula located two thousand light-years from Earth. Taken by the ESO’s Very Large Telescope (VLT) in northern Chile, the photo offers a stunning view of the nebula’s bat-like wings stretched through interstellar space.
NGC 1788 is a reflection nebula that hosts a group of young stars at its core. While NGC 1788 doesn’t emit light, its clouds of gas and dust reflect the light of the stars, thus illuminating the otherwise dim nebula.
The nebula appears to be isolated in space, far from other cosmic objects in Orion (The Hunter). Therefore, astronomers believe the strong stellar winds of distant stars shaped the nebula, giving the Cosmic Bat its contorted appearance, according to a statement from ESO.
The image was taken using the FOcal Reducer and low dispersion Spectrograph 2, or FORS2, instrument mounted on Antu — one of the VLT’s telescopes at the Paranal Observatory.
“Since its first light 20 years ago, FORS2 has become known as ‘the Swiss army knife of instruments.’ This moniker originates from its uniquely broad set of functions,” ESO officials said in the statement. “FORS2’s versatility extends beyond purely scientific uses — its ability to capture beautiful high-quality images like this makes it a particularly useful tool for public outreach.”
The new image offers the most detailed view of the Cosmic Bat taken to date, and it was captured as part of the ESO’s Cosmic Gems program, which is an outreach initiative that uses ESO telescopes and “produces breathtaking images of some of the most striking objects in the night sky,” ESO officials said in the statement.
