NASA reveals a new Hubble image with thousands of multicolored stars



NASA’s Hubble Space Telescope has captured an image showing what the space agency calls a “pocket of stars” – a section of the universe filled with thousands of multicolored stars. The image captures the “globular” cluster called NGC 1805, which is located near the Large Magellanic Cloud, a satellite galaxy of the Milky Way.

Typically, globular clusters contain stars that are born at the same time, NASA said. But NGC 1805 is unusual: Scientists believe it contains two different populations of stars with an age of millions of years.

NASA compared the narrow orbit of stars to bees swarming around a hive. The agency said the stars in the center are unlikely to orbit the planets, because they are 1

00 to 1,000 times closer to each other than the stars closest to our sun.

The cluster is visible from the southern hemisphere in the constellation “Dorado”, which is Portuguese for dolphin fish.

Hubble’s placement in space grants it the unique ability to capture different wavelengths of light. The Earth’s atmosphere absorbs most of the ultraviolet light, making it impossible to observe the difference in the colors of the stars from the ground.

The image combines different types of light to highlight the notable difference in the colors of the stars: blue stars, which shine brighter near ultraviolet light, and red stars, which are brighter in red and near infrared.

Astronomers are interested in observing clusters such as NGC 1805 to learn more about the evolution of stars and the factors that cause them to die white dwarfs against explosive supernovae.
