Hubble Captures Star Cluster in Hues of Crimson, White, and Blue


This image taken with the NASA/ESA Hubble Space Telescope depicts the open star cluster NGC 330, which lies around 180,000 light-years away inside the Small Magellanic Cloud. The cluster – which is in the constellation Tucana (the Toucan) – contains a multitude of stars, many of which are scattered across this striking image.

This week’s Hubble picture is, appropriately sufficient, a star cluster known as NGC 330 which glitters in shades of crimson, white, and blue. Stars seem totally different colours due to the variations of their temperatures and ages, with the most well liked stars glowing blue and the good glowing crimson. There’s a large distinction within the vary of temperatures stars might be, with the most well liked blue stars having a temperature of over 40,000 Kelvin, whereas the good crimson stars might be as little as 2,500 Okay.

At a distance of round 180,000 light-years away, this star cluster is situated contained in the Small Magellanic Cloud. The Small Magellanic Cloud or SMC is a satellite tv for pc galaxy of the Milky Means, that means it’s a smaller companion galaxy which orbits our personal galaxy. The SMC is tiny in comparison with the Milky Means, at simply 7,000 light-years throughout, and incorporates a whole lot of hundreds of thousands of stars. It’s one among a pair of satellite tv for pc galaxies together with its companion, the Large Magellanic Cloud.

In addition to being lovely to look out, observing star clusters is usually a helpful approach to be taught in regards to the lifecycle of stars. Because the Hubble scientists explain, “As a result of star clusters kind from a single primordial cloud of fuel and dirt, all the celebs they comprise are roughly the identical age. This makes them helpful pure laboratories for astronomers to find out how stars kind and evolve.”

So as to create this picture, the Hubble scientists mixed two units of observations which each focused this specific area of house. “This picture makes use of observations from Hubble’s Broad Subject Digicam 3 and incorporates information from two very totally different astronomical investigations,” they write.

“The primary aimed to know why stars in star clusters seem to evolve in another way from stars elsewhere, a peculiarity first noticed with Hubble. The second aimed to find out how massive stars might be earlier than they grow to be doomed to finish their lives in cataclysmic supernova explosions.”
