Next - three #OpenClusters with very different stories #NGC6791 is 8 billion years old, #NGC6939 rocks in at 1 billion while #M29 is the baby at 10 million years old. It's interesting science - most clusters are done and dusted (dissolve) after 500 million... yet some survive MUCH longer 🔭 2/5

A stunning composite image of the Soul Nebula (W5) in Cassiopeia. This vibrant nebula, located 6,500 light-years away, showcases star formation within its fiery, colorful landscape of hydrogen (red), sulfur (yellow), and oxygen (blue) emissions. Dark dust lanes and bright star clusters are visible against the backdrop of a rich star field.

A Double Star Cluster in Perseus

Breathtaking image of the Double Cluster (h and chi Persei, NGC 869 and NGC 884) in the constellation Perseus. These two open star clusters, visible to the naked eye under dark skies, are only a few hundred light-years apart and share a similar age, suggesting a common origin. Cataloged by Hipparchus in 130 BC, they're a stunning binocular target, showcasing bright, young stars against the backdrop of the night sky.

The Pleiades star cluster, also known as the Seven Sisters, is a young, open cluster of stars located in the constellation Taurus. Its hot, blue stars are surrounded by a faint, wispy nebula, remnants of the gas from which they formed.

Not all stars are born alone. Many form in star clusters, groups of stars that share a common origin and age. #StarClusters #StellarEvolution #OpenClusters

Many stars exist in open clusters, relatively loose groups of stars that formed from the same giant molecular cloud. These clusters eventually disperse over time. #OpenClusters #StarClusters #StarFormation

Some exoplanets have been detected orbiting stars in open clusters, less dense groupings of stars than globular clusters. Studying these planets can provide insights into how planetary systems form and evolve in different stellar environments. #OpenClusters #ExoplanetEnvironments #StellarClusters

NASA’s Hubble and Webb Telescopes Reveal Two Faces of a Star Cluster Duo
A riotous expanse of gas, dust, and stars stake out the dazzling territory of a duo of star clusters in this combined image from NASA’s Hubble and Webb space telescopes. Open clusters NGC 460 and NGC 456 reside in the Small Magellanic Cloud, a dwarf galaxy orbiting the Milky Way. Open clusters consist of anywhere […] The post NASA’s Hubble and Webb Telescopes Reveal Two Faces of a Star Cluster Duo first appeared on VibeWire Magazine.
