A Cosmic Bat Takes Flight
The European Space Agency (ESA) released a new image of the Bat Nebula on October 31, coinciding with Halloween. The nebula, located approximately 10,000 light-years from Earth, strikingly resembles a bat with outstretched wings.
The nebula’s eerie shape is formed by swirling clouds of gas and dust. These clouds emit light as hydrogen atoms become energized by radiation from young stars within the nebula, making it a meaningful stellar nursery.
Observational Details
The image was taken using the 268-megapixel Omegacam instrument on the 2.6-meter VLT Survey Telescope at the European Southern Observatory’s Paranal site in Chile’s Atacama Desert. Astronomers utilized a variety of filters to capture the nebula’s light, combining it with infrared observations to reveal its hidden structures.
