CAPE CANAVERAL, Fla. – Astronomers have revealed a nearby spiral galaxy in all its brilliant glory, shining in thousands of colors.
The breathtaking panoramic image unveiled on Wednesday, capturing the Sculptor galaxy, was taken by a telescope in Chile. The detail in this photo is so precise that it already functions as a densely populated star map.
Researchers employed the European Southern Observatory’s Very Large Telescope for their observations of the galaxy, dedicating around 50 hours to gather data. They compiled over 100 separate exposures to assemble the photograph, which covers 65,000 light-years, nearly the galaxy’s entire span. A single light-year equates to 5.8 trillion miles.
The Sculptor galaxy — officially designated as NGC 253 — is identified as a starburst galaxy known for its intense star formation activities. Situated 11 million light-years away within the Southern Hemisphere’s constellation Sculptor, it is easily visible with the aid of binoculars or small telescopes.
“The Sculptor galaxy is in a sweet spot,” the observatory’s Enrico Congiu, who led the research, said in a statement. “It is close enough that we can resolve its internal structure and study its building blocks with incredible detail, but at the same time, big enough that we can still see it as a whole system.”
The more shades of color from stars, gas and dust in a galaxy, the more clues to their age, composition and motion, according to the scientists. Sculptor’s latest snapshot contains thousands of colors — a glowing montage of purples, pinks and yellows — compared with just a handful for traditional pictures.
The team has already discovered 500 planetary nebulae, clouds of gas and dust from dying stars that can serve as cosmic mile markers. Their research has been accepted for publication in the journal Astronomy & Astrophysics.
