UGCA 307 is a small irregular galaxy located approximately 26 million light-years away from Earth in the constellation Corvus. It is part of the Local Group of galaxies that includes our, and it is notable for its diffuse band of stars and red bubbles of gas that signify recent star formation. UGCA 307 is also sometimes referred to as the “Wolf-Lundmark-Melotte” galaxy, named after the astronomers who first discovered it.
. The small galaxy consists of a diffuse band of stars containing red bubbles of gas that mark regions of recent star formation, and lies roughly 26 million light-years from Earth in the constellation Corvus. Appearing as just a small patch of stars, UGCA 307 is a diminutivewithout a defined structure — resembling nothing more than a hazy patch of passing cloud.
This image is part of a Hubble project to explore every known nearby galaxy, giving astronomers insights into our galactic neighborhood. Before this set of observations, almost three quarters of nearby galaxies had been investigated by Hubble in enough detail to spot the brightestand build up an understanding of the stars populating each galaxy. This Hubble project set out to explore the remaining quarter of nearby galaxies by taking advantage of short gaps in Hubble’s observing schedule.
This crystal-clear image was captured by Hubble’s Advanced Camera for Surveys , which was installed on the telescope in 2002 during. Hubble’s vantage point in low Earth orbit means that it is above atmospheric turbulence, giving it a sharper view of the Universe. However, it is also close enough to Earth that astronauts could visit the telescope to repair and refurbish the telescope.
