NASA Astronomy Picture of the Day 15 June 2023: M15 Globular Star Cluster snapped by Hubble

[ad_1] Over the past few months, we've seen several amazing images of celestial objects as part of NASA Astronomy Picture of the Day, which is published on a daily basis featuring astrophotographers from around the world. Some of these include snapshots of fascinating celestial objects documented by Charles Messier. The French astronomer studied and catalogued these objects in Catalogue des Nébuleuses et des Amas d'Étoiles and the catalogue is today known as the Messier Objects which contains 110 objects. Today's NASA Astronomy Picture of the Day is a breathtaking snapshot of M15, a globular star cluster that is located about 33600 light-years away towards the constellation of Pegasus. According to NASA, Messier 15 is one of the densest ever discovered, with hot blue stars and cooler or...

NASA Astronomy Picture of the Day 13 April 2023: Globular Star Cluster NGC 2419

[ad_1] 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 light-years away towards the constellation of Lynx. According to NASA, the stars populating globular clusters are very similar because they formed at roughly the same time and because of this, they tend to display similar properties. Tech which helped capture the ima...

NASA Astronomy Picture of the Day 30 March 2023: Globular star cluster and Dark Doodad Nebula

[ad_1] 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 spherical shape that holds a bright, central concentration of stars surrounded by an increasingly sparse sprinkling of stars.Today's NASA Astronomy Picture of the Day is the Dark Doodad Nebula which lies beside the globular star cluster NGC 4372. Also known as Caldwell 10...

NASA Astronomy Picture of the Day 20 February 2023: Hubble snaps Stellar double Star Cluster

[ad_1] NASA Astronomy Picture of the Day 20 February 2023: Our universe is illuminated by trillions of stars in the sky. These bright objects are formed in a giant cloud of dust and gas in space, known as a Nebula. After formation, many stars 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. Sometimes, sky watchers might confuse star clusters in our own Milky Way Galaxy with clusters in other galaxies due to their similar appearance.One of these star clusters is NGC 1850, which makes NASA's Astronomy Picture of the Day. It is a 100-million-year-old globular star cluster located 160,000 light-years away in the constellation Dorado. What's unusual about this star cluster is its size and shape is remini...

NASA Astronomy Picture of the Day 30 January 2023: Hubble snaps Globular Star Cluster 6355

[ad_1] 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 stars, but Hubble has also captured breathtaking images of groups of stars, known as Star Clusters.NASA's Astronomy Picture of the Day is a breathtaking snapshot of the Globular Star Cluster NGC 6355, which is nearly 13 billion years old. Stars are celestial objects m...
