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

This picture taken with the NASA/ESA Hubble Space Telescope depicts the open star cluster NGC 330, which lies round 180,000 light-years away contained in the Small Magellanic Cloud. The cluster – which is within the constellation Tucana (the Toucan) – comprises a mess of stars, a lot of that are scattered throughout this hanging picture. ESA/Hubble & NASA, J. Kalirai, A. Milone

This week’s Hubble picture is, appropriately sufficient, a star cluster referred to 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 best glowing crimson. There is a big 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 best crimson stars might be as little as 2,500 Ok.

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 Way, that means it’s a smaller companion galaxy which orbits our personal galaxy. The SMC is tiny in comparison with the Milky Way, at simply 7,000 light-years throughout, and comprises a whole bunch of hundreds of thousands of stars. It is one among a pair of satellite tv for pc galaxies together with its companion, the Large Magellanic Cloud.

As properly as being stunning to look out, observing star clusters is usually a helpful technique to study in regards to the lifecycle of stars. As the Hubble scientists explain, “Because star clusters form from a single primordial cloud of gas and dust, all the stars they contain are roughly the same age. This makes them useful natural laboratories for astronomers to learn how stars form and evolve.”

In order to create this picture, the Hubble scientists mixed two units of observations which each focused this specific area of house. “This image uses observations from Hubble’s Wide Field Camera 3 and incorporates data from two very different astronomical investigations,” they write.

“The first aimed to understand why stars in star clusters appear to evolve differently from stars elsewhere, a peculiarity first observed with Hubble. The second aimed to determine how large stars can be before they become doomed to end their lives in cataclysmic supernova explosions.”
