Open Cluster M50 - January 28th, 1997.

"Many stars form in clusters. Two types of star clusters are visible in our Milky Way galaxy: open clusters and globular clusters. Open clusters like M50, shown above, typically contain hundreds of stars, many of which are bright, young, and blue. In fact, most of the bright blue stars in the above picture belong to M50, but most of the dimmer, red stars do not. M50 lies about 3000 light-years from Earth and is about 20 light-years across. Open clusters tend to have irregular shapes and are mostly found in the plane of our galaxy."

"THIS STUNNING, DEEP VIEW OF THE LAGOON IS NEARLY 100 LIGHT-YEARS ACROSS."

PIC INFO: Resolution at 1401x2048 -- Spotlight on the The Wide and Deep Lagoon. 📸/🔭: Image & Copyright: Michael Miller, Jimmy Walker.

EXPLANATION/OVERVIEW: "Ridges of glowing interstellar gas and dark dust clouds inhabit the turbulent, cosmic depths of the Lagoon Nebula. Also known as M8, the bright star forming region is about 5,000 light-years distant. But it still makes for a popular stop on telescopic tours of the constellation Sagittarius, toward the centre of our Milky Way Galaxy. Dominated by the telltale red emission of ionized hydrogen atoms recombining with stripped electrons, this stunning, deep view of the Lagoon is nearly 100 light-years across. Right of centre, the bright, compact, hourglass shape is gas ionized and sculpted by energetic radiation and extreme stellar winds from a massive young star. In fact, the many bright stars of open cluster NGC 6530 drift within the nebula, just formed in the Lagoon several million years ago."

The Pleiades star cluster, my personal favorite!

Some of my favourite star clusters!

The Pleiades Star Cluster - September 3rd, 1996.

"It is the most famous star cluster in the sky. The Pleiades can be seen without binoculars from even the depths of a light-polluted city. Also known as the Seven Sisters and M45, the Pleiades is one of the brightest and most easily visible open clusters in the sky. The Pleiades contains over 3000 stars, is about 400 light years away, and is only 13 light years across. Quite evident in the above photograph is the blue reflection nebula that surrounds the bright cluster stars. Low mass, faint, brown dwarfs have been found in the Pleiades."

The Double Cluster in Perseus consists of two open star clusters near each other on the sky’s dome. Amateur astronomers know them as h and Chi Persei. The two clusters reside in the northern part of the constellation Perseus, quite close to the constellation Cassiopeia the Queen. If you have a dark sky and find Cassiopeia – which is easy, because the constellation has a distinctive M or W shape – be sure to look for Perseus, too. Then just scan between the two constellations with your binoculars for two glittering groups of stars. The Double Cluster – a breathtaking pair of open clusters, each containing supergiant suns – will be there.

#SomewhereDeepInTheNight "This image was obtained with the wide-field view of the Mosaic camera on the WIYN 0.9-meter telescope on Kitt Peak, Arizona. The Pleiades are an open cluster easily visible to the naked eye. The cluster is dominated by several hot, luminous and massive stars. The blue nebulosity surrounding the brightest stars are due to blue light from the stars scattering off of dust grains in the interstellar gas between us and the stars. The cluster is also known as the 'Seven Sisters'. And in Japan it is called Subaru. " NOIRLab
