NASA Astronomy Picture of the Day 31 January 2023: Green Comet ZTF over Spain

[ad_1] NASA’s Astronomy Picture of the Day is a snapshot of the rare Green Comet ZTF captured in the skies above Spain. NASA Astronomy Picture of the Day 31 January 2023: A comet orbits the Sun, but unlike an asteroid, it's composed of ice and dust. When a comet gets close to the Sun, its ice and dust content start to vaporize. So, when seen in a telescope, a comet appears fuzzy and has a tail. If you are a fan of watching comets, there is some exciting news for you. A comet which was last seen by Neanderthals is all set to pass Earth this year. The comet is called Comet C/2022E3 (ZTF). It is a long-period comet that originated in the Oort cloud.NASA's Astronomy Picture of the Day is an image of the Comet ZTF captured in a triple view in Caceres, Spain, by astrophotographers Javier Ca...

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...

NASA Astronomy Picture of the Day 27 January 2023: Green Comet ZTF lights up the sky

[ad_1] NASA’s Astronomy Picture of the Day is a stunning snapshot of the Rare Green Comet ZTF crossing the orbital plane. Comets are of interest to scientists because they are remnants of the early Solar System, and can tell us about the conditions and composition of the early Solar System. When a comet approaches the Sun, the heat causes the ices in the comet to turn into a gas, which surrounds the nucleus of the comet in a bright coma. The gas and dust in the coma form a bright tail that always points away from the Sun. The Earth will soon get to witness a historic moment. An extremely rare comet named Comet C/2022 E3 (ZTF), which last visited us when humanity still lived in caves, is going to pay us a visit.The comet has a period of around 50,000 years, meaning the last time it fle...

NASA Astronomy Picture of the Day 26 January 2023: Dazzling Active Galaxy

[ad_1] NASA’s Astronomy Picture of the Day is a mesmerizing snapshot of the Active Galaxy NGC 1275 residing at the center of Perseus Galaxy Cluster. In the Universe, galaxies exist in the vast expanse of space. But they are not alone. In fact, galaxies exist in huge groups which are closely connected by gravity. Most galaxies exist in groups or clusters with dozens or hundreds of members, and these cluster galaxies are all in constant motion, pulled and twisted by their neighbour's gravity. Galaxy clusters are the largest objects in the Universe bound by gravity and astronomers can use them to measure important cosmological properties, according to NASA.Galaxy Clusters are also known to contain dark matter which is invisible to telescopes since they do not emit, absorb, or reflect any...

NASA Astronomy Picture of the Day 25 January 2023: The Enchanting Lynds’ Dark Nebula

[ad_1] NASA's Astronomy Picture of the Day is an enchanting snapshot of Lynds' Dark Nebula captured by astrophotographer Joshua Carter. Nebulas exist in the space between stars, known as the Interstellar space. In fact, there is a Nebula close to Earth which could possibly be the remnant of the dying star, according to NASA. It is called the Helix Nebula and is located approximately 700 light-years away from Earth. NASA captures the Nebulas with the help of its Spitzer Space Telescope, Hubble Space Telescope and the new James Webb Space Telescope.Lynds' Dark Nebula is a catalog of over 700 dark nebulae discovered by American astronomer Barbara Lynds in the 1960s. Dark nebulae are clouds of dust and gas that block the light from stars and other objects behind them, making them appear d...

NASA Astronomy Picture of the Day 24 January 2023: Webb’s exoplanet discovery generated by AI

[ad_1] NASA’s Astronomy Picture of the Day is a stunning AI-generated picture of an exoplanet named LHS 475 b. Humans have been on the hunt for an Earth-like planet for years. The space race has led mankind to the Moon, Mars and even the outer solar system. Space agencies like NASA, ISRO, CNSA and ESA use their extensive resources to search for potential planets which could support life one day should the need to ever leave Earth arise. Although there are more planets in the Universe than you could ever imagine, only a handful of them have the potential to support life one day.To search for habitable planets which could potentially support life, NASA launched its Transiting Exoplanet Survey Satellite (TESS) on April 18, 2018. TESS is an all-sky survey mission that will discover thousa...

NASA Astronomy Picture of the Day 23 January 2023: Hubble snaps collision of galaxies

[ad_1] 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.

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...
