NASA’s Astronomy Picture of the Day is a stunning snapshot of two galaxies colliding almost 400 million light-years away from Earth. NASA Astronomy Picture of the Day 23 January 2023: Galaxies are large collections of stars, gas, dust, and dark matter held together by gravity. They come in a variety of sizes, from small dwarf galaxies with only a few billion stars to giant elliptical galaxies with trillions of stars. Although most galaxies have elliptical shapes, a few have unusual shapes like toothpicks or rings. Most…

NASA’s Astronomy Picture of the Day is a breathtaking snapshot of two dominant galaxies locked in gravitational combat. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, according to NASA. A galaxy is held together by gravity. They come in a variety of sizes, from small dwarf galaxies with only a few billion stars to giant elliptical galaxies with trillions of stars. Although most galaxies have elliptical shapes, a few have unusual shapes like toothpicks or rings.NASA's…

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…

NASA’s Astronomy Picture of the Day is a captivating image of a galaxy cluster captured by the James Webb Telescope. The James Webb Space Telescope is impressing us with its capabilities with each passing day. NASA's $10 billion space telescope has been capturing breathtaking images of far-off galaxies, star clusters, black holes and more. The space telescope was launched on December 25, 2021 and since then it has added many feathers in its cap. One such image was of Galaxy clusters, which are some of the largest…

NASA’s Astronomy Picture of the Day is a riveting snapshot of the Andromeda Galaxy and the oxygen-emitting blue arcs that surround it. The Andromeda Galaxy is one of the most distant, yet easily visible objects to the eye. Also known as Messier 31, it is a spiral galaxy located approximately 2.5 million light-years away from Earth in the constellation Andromeda. According to NASA, the Andromeda Galaxy is twice the size of our own Milky Way Galaxy, spanning across nearly 260,000 light-years and containing over 1…

NASA’s Astronomy Picture of the Day is a stunning image of the Moon, showing all of its features in detail. The Moon has long been one of the central pieces of the studies related to Earth. Its presence influences various phenomena on the planet, such as tides. The Moon is believed to have formed about 4.5 billion years ago, shortly after the formation of the solar system. According to one theory , a huge Mars-sized celestial object called Theia collided with Earth around 4.5 billion years ago and the Moon was formed…

NASA’s Astronomy Picture of the day is a mesmerizing snapshot of a young star cluster in the Small Magellanic Cloud. Group of stars that are close to each other bound together by mutual gravitational attraction are known as star clusters. Stars 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, forming a Star Cluster. According to NASA, Star clusters can contain as few as ten stars or as…

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…

NASA’s Astronomy Picture of the Day is a mesmerizing snapshot of Auroras spiralling over the night-sky in Iceland. Scientists have long studied Auroras to better understand the workings of Earth's magnetic field and the solar wind. Auroras, also known as the Northern and Southern Lights, put on a mesmerizing show of lights in the night skies of the polar regions. Although auroras are usually green in colour, they can appear as pink sometimes too. Green auroras are formed when energy particles hit the oxygen atoms at…

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…
