NASA Astronomy Picture of the Day 6 February 2023: Heart of the Rosette Nebula

[ad_1] A breathtaking image of a nebula, which is around 5200 light-years away from Earth has been featured as the NASA Astronomy Picture of the Day. While explaining the image, NASA says in the heart of the Rosette Nebula, there lies a bright cluster of stars that light up the nebula. NGC 2244's stars only formed a few million years ago from the surrounding gas. The center of the Rosette Nebula, visible through binoculars in the Monoceros constellation, measures about 50 light-years in diameter.NASA further mentioned that the featured image was captured in mid-January using multiple exposures and specific colours. Sulfur is shown in red, Hydrogen in green, and Oxygen in blue, providing a highly detailed view of the central region. A hot wind of particles from the cluster stars contrib...

NASA Astronomy Picture of the Day 4 February 2023: A nebula-3200 light years away

[ad_1] Nebula is nothing but the beginning of a star! How? NASA explains that Nebulae are composed of dust and gaseous matter, primarily hydrogen and helium. Despite being dispersed, gravity can cause clumps of dust and gas to converge over time, leading to increased gravitational pull. Once these clumps become substantial, they collapse under their own gravity, heating up the central material and forming the beginnings of a star.Today's NASA's Astronomy Picture of the Day is NGC 2626, a beautiful, bright, blue reflection nebula in the southern Milky Way which is centered in this colourful cosmic canvas. NGC 2626 is located near a dusty cloud and encircled by reddish hydrogen emissions from the H II region RCW 27. It is part of a group of dusty molecular clouds called the Vela Molecula...

Hubble Space Telescope snaps spectacular image of Orion Nebula

[ad_1] NASA's Hubble Space Telescope snapped an amazing image of Orion Nebula with the help of two of its special instruments. NASA's Hubble Space Telescope has been in orbit since 1990. It has been in service for more than 32 years and since then it has delivered some spectacular views of space, star formations, nebulae, galaxies, exoplanets, and much more. The latest breathtaking image captured by the Hubble Space Telescope shows a stunning view of the bright variable star V 372 Orionis. It also captured a smaller companion star in the upper left of this image. Both of these stars are located in the Orion Nebula, a massive star forming region that is roughly 1450 light-years away from Earth.Data from two Hubble instruments are superimposed on this image. Rich details of this region ...

James Webb Telescope, Chandra Observatory snap astonishing Tarantula Nebula image

[ad_1] NASA’s James Webb Space Telescope has teamed up with the Chandra X-ray Observatory to show an astonishing view of the Tarantula Nebula. Last year, NASA's James Webb Space Telescope snapped the Tarantula Nebula, also called 30 Doradus, located in the Large Magellanic Cloud, a small neighbouring galaxy to the Milky Way Galaxy. It has long been studied by astronomers to better understand how stars like the Sun are born and evolve. Now, NASA's Chandra X-ray Observatory and James Webb Telescope have teamed up to reveal an astonishing view of the Tarantula Nebula. The new composite image combines X-ray data from the Chandra X-ray Observatory and infrared images from the James Webb Space Telescope to show a stellar view of the Nebula."The X-rays (royal blue and purple) reveal gas that...

NASA Astronomy Picture of the Day 15 January 2023: Hubble Telescope snaps spooky Crab Nebula

[ad_1] NASA’s Astronomy Picture of the Day for 15 January, 2023 is one of a spooky Crab Nebula image captured by the Hubble Telescope. NASA Astronomy picture of the day takes everyone into a fascinatingly different dimension of the cosmos on a daily basis. Today, it took an eerie turn with a an image of a Crab Nebula! “This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments,” NASA explained about the images. The filaments in the image are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion.This image has been captured by NASA's Hubble Space Telescope, while the surprising fact is that the Crab...

NASA Hubble Telescope captures mesmerizing 4-mn year old Nebula bubble

[ad_1] NASA’s Hubble Telescope has shared a breathtaking Nebula Bubble, which is 4 million years old. Even after 32 years of service, NASA's old Hubble Space Telescope has captured another breathtaking glimpse from deep space, revealing the cosmic Bubble Nebula. The stunning image depicts one of the most famous star bubbles, a cosmic bubble wrap which is 7100 light-years away from Earth in the constellation Cassiopeia. NASA shared the image on its Instagram account while revealing that this Nebula has a star 45 times more massive than our own.⁣While sharing the picture, NASA says, "Gas on the star gets so hot that it escapes into space at a speed of 4 million miles per hour (6.4 million kilometers per hour); when the hot "stellar wind" meets the surrounding rigidness of space, it fold...

Childhood of stars shapes stellar evolution

[ad_1] Scientists now show that the biography of stars is indeed shaped by their early stage. In classical models of stellar evolution, so far little importance has been attached to the early evolution of stars. Scientists now show that the biography of stars is indeed shaped by their early stage. From babies to teenagers: stars in their "young years" are a major challenge for science. The process of star formation is particularly complex and difficult to map in theoretical models. One of the few ways to learn more about the formation, structure or age of stars is to observe their oscillations. "Comparable to the exploration of the Earth's interior with the help of seismology, we can also make statements about their intern...

How massive stars steal planets – new research

[ad_1] Our Sun has a rather lonely existence in the Milky Way galaxy. It sits on its own, four light years away from the nearest star, with only its planetary system for company. But it wasn’t always like this. Our Sun has a rather lonely existence in the Milky Way galaxy. It sits on its own, four light years away from the nearest star, with only its planetary system for company. But it wasn't always like this. We almost exclusively observe young stars in groups, so-called stellar nurseries, where they brush shoulders with stellar siblings.These stellar nurseries are densely populated places, where hundreds of thousands of stars often reside in the same volume of space that the Sun inhabits on its own. Violent interactions, i...
