NASA Astronomy Picture of the Day 19 January 2023: Bewitching Star-forming Seagull Nebula

[ad_1] NASA Astronomy Picture of the Day 19 January 2023: Bewitching Star-forming Seagull Nebula located in the constellation Monoceros. NASA defines stars as 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. But how are these bright and shining objects formed? Wellm stars are formed in star-forming regions called Nebulas. 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 li...

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 10 January 2023: Mesmerizing Cone Nebula captured

[ad_1] NASA's Astronomy Picture of the Day provides a mesmerizing view of the star-forming region known as Cone Nebula. The region of a galaxy where stars are forming at an especially high rate is known as a Star Nursery or a Nebula. These star-forming regions are usually found in the spiral arms of galaxies, where there is a high density of molecular clouds. 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 new star is born.NASA's Astronomy Picture of the Day is a bewitching picture of a star-forming region known as a Cone Nebula. This Nebula has been g...

NASA Astronomy Picture of the Day 16 December 2022: Take a glimpse of Thor’s Helmet Nebula

[ad_1] NASA’s astronomy picture of the day is a mesmerizing picture of the Thor’s Helmet Nebula located thousands of light-years away from Earth. NASA Astronomy Picture of the Day 16 December 2022: Thor is the Norse hammer-wielding god, also known as the God of Thunder. Besides protecting his own land of Asgard, the Asgardian is also the protector of humankind. Thor is often likened to the planet Jupiter due to the lightning and thunder factor. He even has a day named after him – Thursday! But that's not all. It seems like even the vast emptiness of space bows down to him as there exists a Nebula resembling the Norse god's helmet!Today's NASA Astronomy Picture of the Day is a mesmerizing image of a cosmic cloud termed NGC 2359. Astonishingly, the Nebula is also called Thor's Helmet du...

NASA Astronomy Picture of the Day 12 December 2022: Elephant’s Trunk Nebula shot by NASA

[ad_1] NASA’s astronomy picture of the day is a mesmerizing snapshot of Elephant’s Trunk Nebula. 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. This is why a Nebula is also called a Star Nursery.NASA releases its Astronomy picture of the day on a daily basis. December 12's image is a mesmerizing snapshot of the Elephant's Trunk Nebula. The image was captured by astronomer Bernard Miller, an Arizona based retired electronic design engineer. He captured the image with the help of his o...
