Globular

Globular clusters are stable, tightly bound groups of tens of thousands to millions of stars that are associated with all types of galaxies. According to NASA, it is possible that globular star clusters once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are less than 200 left.Today's NASA Astronomy Picture of the Day is the globular star cluster NGC 2419. It is a multi-generational star cluster located about 300,000…

After the formation of stars takes place in a nebula, many of them form groups from the same Nebula, forming a Star Cluster. Star clusters can contain as few as ten stars or as many as millions of stars. One type of star cluster is the globular star cluster. Globular clusters are stable, tightly bound groups of tens of thousands to millions of stars that are associated with all types of galaxies, according to NASA. Their dense populations of stars and mutual gravitational attraction give these clusters a roughly…

Detail of the globular cluster Messier 92 (M92) captured by Webb’s NIRCam instrument. This field of view covers the lower left quarter of the right half of the full image. Globular clusters are dense masses of tightly packed stars that all formed around the same time. In M92, there are about 300,000 stars packed into a ball about 100 light-years across. The night sky of a planet in the middle of M92 would shine with thousands of stars that appear thousands of times brighter than those in our own sky. The image shows stars…

NASA’s Astronomy Picture of the Day is a breathtaking snapshot of a group of stars known as Globular Star Cluster NGC 6355. Although the new James Webb Space Telescope has been capturing incredible images of celestial events, the Hubble Space Telescope has once again proved that, even though it may be old, it is still capable of capturing breathtaking images. Since the launch of Hubble in 1990, it has become relatively very easy to observe distant stars due to its presence about 340 miles above the Earth. Not just…

Hubble Telescope continues to impress despite the new kid in town, James Webb Space Telescope. Now, NASA's old Hubble Space Telescope has captured a stunning globular cluster of stars. Although the brand-new James Webb Space Telescope has recently captured some incredible images of celestial events, the Hubble Space Telescope has once again proved that it even though it may be old, it is still capable of capturing breathtaking images. Hubble Telescope has just captured a mesmerizing image of a scattered cluster of…

The Hubble space telescope might have a few decades under its belt, but it continues to deliver images that keep it working alongside the James Webb Space Telescope – its more powerful successor. The latest showcase of Hubble’s capabilities comes in the form of two photos of the NGC 1850 star cluster, which look startlingly different. The images might look quite different, but NASA says they were taken in the same region of space. The difference in colors and what we see, though, is caused by utilizing two…

CohenTerzan 1 is a globular cluster located around 22,000 light-years away from Earth in the constellation Scorpius. It is one of 11 globular clusters that were discovered by the Turkish-Armenian astronomer Agop Terzan between 1966 and 1971. This is a time period when he was working in France, based mostly at Lyon…
