NASA’s James Webb Space Telescope snaps NGC 604, unlocks some star formation mysteries

[ad_1] Stars are born in chaotic and fascinating environments, and scientists are eager to understand more about these processes. And at the forefront of this exploration is US space agency NASA's James Webb Space Telescope. Ever since its launch, it is helping astronomers see these celestial events like never before.Recently, James Webb Space Telescope captured two stunning images of NGC 604, a place in the Triangulum galaxy where stars are forming. It's about 2.73 million light-years away from Earth. These images show us bubbles and long strands of gas where stars are being born. Inside NGC 604, there are over 200 very hot and massive stars. These stars, called B-types and O-types, are rare in our cosmic neighborhood. There's nowhere quite like NGC 604 in our own Milky Way galaxy. Bec...

NASA’s Hubble Space Telescope image reveals massive star birth in celestial tapestry

[ad_1] n a vibrant display of cosmic artistry, the NASA's Hubble Space Telescope has captured a captivating image of the star-forming region IRAS 16562-3959 within the Milky Way Galaxy. Situated approximately 5,900 light-years away in the Scorpius constellation, this celestial panorama reveals a dynamic tapestry of colours and activities.Hubble's Precision PaletteThe mesmerising snapshot, composed by Hubble Telescope's Wide Field Camera 3, unveils the intricacies of IRAS 16562-3959 through the lens of four specialised filters. These filters, akin to thin slivers of expertly crafted material, selectively allow specific wavelengths of light to pass through, offering a detailed exploration of the region's composition, temperature, and density. The Enigmatic CoreAt the heart of the image li...

Webb Telescope snaps 45000 galaxies in ONE frame; universe seen like never before

[ad_1] The James Webb Space Telescope (JWST) has made significant contributions to our understanding of how galaxies and stars came into existence. NASA recently shared an infrared image captured by Webb as part of the JWST Advanced Deep Extragalactic Survey (JADES) program, shedding more light on the vast expanse of the universe.This particular image focuses on a region of the sky known as GOODS-Sout. Amazingly this one photo packs over 45,000 galaxies, as reported by NASA. Researchers from the University of Texas at Austin conducted a study of galaxies that emerged 500 to 850 million years after the Big Bang, also referred to as the Epoch of Reionisation. During this epoch, the universe was shrouded in a gaseous fog that rendered it opaque. Approximately one billion years after the Bi...

NASA Astronomy Picture of the Day 21 March 2023: Dark Nebulae and the Taurus Molecular Cloud

[ad_1] When gas, dust and plasma get accumulated in space, it usually leads to the formation of interstellar clouds. Initially, these clouds are hot in nature but when they become dense and cool enough, molecules form inside them, giving them the name of Interstellar Molecular Clouds. Molecular clouds are places where stars first form and they help astronomers in learning about the earliest stages of stars. According to NASA, these celestial objects are so dense that the dust within blocks visible wavelengths of light. Telescopes that see visible light only detect ghostly dark patches in the sky, called Dark Nebulae.Today's NASA Astronomy Picture of the Day is a fascinating snapshot of the dark nebulae and the star formation in the Taurus Molecular Cloud (TMC). Located about 400 light-...

NASA Webb telescope captures star on cusp of death

[ad_1] The Webb Space Telescope has captured the rare and fleeting phase of a star on the cusp of death.NASA released the picture Tuesday at the South by Southwest conference in Austin, Texas. The observation was among the first made by Webb following its launch in late 2021. Its infrared eyes observed all the gas and dust flung into space by a huge, hot star 15,000 light-years away. A light-year is about 5.8 trillion miles. Shimmering in purple like a cherry blossom, the cast-off material once comprised the star's outer layer. The Hubble Space Telescope snapped a shot of the same transitioning star a few decades ago, but it appeared more like a fireball without the delicate details.Such a transformation occurs only with some stars and normally is the last step before they explode, goi...

NASA Astronomy Picture of the Day 24 February 2023: Death Shroud! Here is Headphone Nebula

[ad_1] According to NASA, a nebula is a vast collection of gas and dust in space. These celestial objects can be found in the Interstellar space that separates stars. There are two types of nebulae: those that are created by the remnants of a dying star, and those that serve as regions where stars are formed and eventually birthed. Although many nebulae are located extremely far away, NASA has been able to observe them using advanced technology such as the Spitzer Space Telescope, the Hubble Space Telescope, and the recently launched James Webb Space Telescope.NASA's Astronomy Picture of the Day is a mesmerizing snapshot of a stellar nebula known as Jones-Emberson 1. It is also called as the Headphone Nebula owing to its peculiar headphone-like shape. The Headphone Nebula is located ab...

Awesome find! Indian scientists detect radio signal from 9bn years ago

[ad_1] Indian astronomers have detected a radio signal from a distant galaxy that is as old as around 9 billion years. The latest study looked back in time to the early universe to answer some of the most-asked questions - "How do stars form in the early galaxies?" To answer this, many astronomers have been trying to detect radio signals emitted by nearby galaxies. However, the difficulty to pick up the signal intensifies with the distance of the galaxy from the Earth. The vast expansion of the universe causes the reduction in energy due to the stretch of its wavelength. This means, telescopes available on Earth require a natural boost to detect long-wavelength and low-energy radio waves. Now, Indian Astronomers have captured a radio signal, that too from the most distant galaxy at ...

Never been seen before! James Webb Space Telescope reveals ethereal forming star

[ad_1] The James Webb Space Telescope unveiled its latest image of celestial majesty, an ethereal hourglass of orange and blue dust being shot out from a newly forming star at its centre. The James Webb Space Telescope unveiled its latest image of celestial majesty on Wednesday, an ethereal hourglass of orange and blue dust being shot out from a newly forming star at its centre.The colourful clouds are only visible in infrared light, so had never been seen before being captured by Webb's Near-Infrared Camera (NIRCam), NASA and the European Space Agency said in a statement. The very young star, known as protostar L1527, is hidden in darkness by the edge of a rotating disk of gas at the neck of the hourglass. However light spills out from the top and bottom of the disk, lighting up the ...

Brilliant! NASA’s JWST photo shows planet being BORN; Check out stunning image

[ad_1] An awesome NASA photo, taken by James Webb Space Telescope, shows a star being born in Eagle Nebula. It is virtually in the womb. The James Webb Space Telescope, operated by NASA, has captured the STUNNING formation of a star. The NASA photo shows a planet virtually in the womb itself for all intents and purposes. It is a gas giant in the earliest stages of birth. NASA has captured the spectacular image from the Eagle Nebula's towering tendrils of gas and dust, known as the "Pillars of Creation." These permeable pillars that appear semi-transparent in near-infrared light. Nasa said that these solid rock formations are actually interstellar gases. As per the report, the region is located 6,500 light-years from Earth and within the Eagle Nebula. It was previously seen by the Hu...

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...
