NASA Astronomy Picture of the Day 12 January 2023: Star Cluster and Flying Ghost Nebula captured

[ad_1] NASA’s Astronomy Picture of the Day is a stunning picture of the star cluster and the Flying Ghost Nebula surrounded by stardust. Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. They are celestial objects millions of years old floating in space. The older and bigger the star, the brighter it appears. They are formed in star-forming regions called Nebulae. The makeup of a Nebula consists of gases, mainly hydrogen and helium. Gravity within a molecular cloud causes the gas and dust to collapse, forming dense cores. As the cores grow denser and hotter, they begin to fuse hydrogen atoms into helium, which releases energy in the form of light and heat. Once a core reaches a certain temperature and density, a ...

NASA Astronomy Picture of the Day 5 January 2023: The Pleiades Star Cluster

[ad_1] NASA’s Astronomy Picture of the Day is a stunning picture of the Pleiades star cluster, the cosmic cloud located 400 light-years away from Earth. Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. They are celestial objects millions of years old floating in space. The older and bigger the star, the brighter it appears. They are formed in star-forming regions called Nebulae. The makeup of a Nebula consists of gases, mainly hydrogen and helium. After formation, many stars form groups from the same Nebula, which is known as a Star Cluster. According to NASA, Star clusters can contain as few as ten stars or as many as millions of stars.NASA's Astronomy Picture of the Day is of the Pleiades Star Cluster with its...

NASA Astronomy Picture of the Day 3 January 2023: Kemble’s Cascade of Stars adorns the sky

[ad_1] NASA’s Astronomy Picture of the Day is a mesmerizing picture of an Asterism known as Kemble's Cascade of Stars. Stars are celestial objects millions of years old floating in space. The older and bigger the star, the brighter it appears. Stars are the most widely recognized astronomical objects, and represent the most fundamental building blocks of galaxies. They are formed in star-forming regions called Nebulas. The makeup of a Nebula consists of gases, mainly hydrogen and helium. Although these gases are spread out, they can be pulled together by gravity. As they clump together, their gravity increases by such an amount that the gas cloud collapses, causing the material at the center of the core to heat up, and this is the birth of a star, according to NASA.Grouped stars somet...
