The Hubble Space Telescope Spots Farthest Star Ever SeenNASA announced a new record today. The light that began its journey from a star 12.9 billion years ago has reached the Hubble Space Telescope, making it the furthest star humans have ever seen. That means this particular star existed within the first billion years of the universe's existence. The star has been dubbed Earendel, which is an Old English word for morning star. Earendel is (or was 12 billion years ago) more than 50 times as big as our sun, and millions of times brighter. Since it is so distant and so old, it may be made up of different material than more familiar stars. The previous record for the most distant star ever seen was a four-billion-year-old star detected in 2018. The new star Earendel is ripe for study, as NASA’s James Webb Space Telescope will be focusing on it for more information. Read more about the discovery of Earendel and what it tells us about the early universe at NASA. -via reddit#star #Hubble #NASA #Earendel

Three Galaxies Swirling Into Each Other Captured by the Hubble Space TelescopeThe Hubble Space Telescope has captured a fascinating image distant galaxies in the process of merging. The three galaxies IC 2431, located 681 million light-years away from Earth, are swirling into each other with a thick cloud of dust obscuring the center of the image. Light from a background galaxy was seen piercing through the outer parts.The image was found by Galaxy Zoo citizen science project, in which more than 100,000 volunteers sift through 900,000 unexamined galaxies as captured by the Hubble Space Telescope. Weird and interesting finds are then given to astronomers to take closer looks.The Galaxy Zoo shows how powerful a crowdsourced project could be: what would have been years of work for professional astronomers was  achieved in just 175 days.Image: ESA/Hubble & NASA, W.

Hubble Gives us a Closer Look at at Old Movie StarsOn December 18, the Astronomy Picture of the Day was of Stephan's Quintet, a view of five galaxies, four of which are about 300 million light years away. This image was taken by the Hubble space telescope in 2009. But you've seen these galaxies before, without even realizing it. It was the opening scene of the 1946 film It's a Wonderful Life, when the angels are talking about sending Clarence Oddbody down to save George Bailey.

Like a Galactic Lightsaber Piercing a Celestial Heart: Hubble's Wide Field Camera3 Captured a Herbig-Haro ObjectThe unusual celestial phenomenon seen in this stunning picture is known as a Herbig-Haro Object. This specific object is named HH111 and was captured by Hubble’s Wide Field Camera 3 or WFC3. These picturesque objects are formed under specific conditions where newly formed stars are very active and, in some cases, expel narrow jets of rapidly moving ionized charges. The stream of ionized gas then collides with the clouds of gas and dust around the newly formed stars at insane speeds of hundreds of kilometers per second.Herbig-Haro objects emit a lot of visible light, but they are surrounded by gas and dust, which absorb the light. WFC’s ability to observe at both optical and infrared wavelengths mean that it is able to observe the Herbig-Haro objects as infrared is not affected by the gas and dust.#Space #Hubble #Astronomy #Camera #HerbigHaro #NASA #ESAImage Credit: ESA/Hubble & NASA, B.
