NASA shares Hubble Space Telescope’s snap of LEDA 42160 galaxy that is 52 mn light-years away

[ad_1] In the vastness of space, galaxies journey through the cosmos, encountering mind-boggling challenges along the way. One such challenge is ram pressure, a force exerted by the gas and dust present in space. NASA and ESA-run Hubble Space Telescope recently captured an image showcasing the effects of this on a distant galaxy known as LEDA 42160.Situated approximately 52 million light-years away in the constellation Virgo, LEDA 42160 is a dwarf galaxy navigating through the dense gas within the Virgo cluster of galaxies. This intergalactic gas creates a pressure, known as ram pressure, which directly impacts the star formation processes within LEDA 42160. Ram pressure can have both positive and negative effects on galaxies. On one hand, it can strip a galaxy of its star-forming gas a...

NASA’s Hubble Telescope captures stellar Butterfly Nebula; Know all about NGC 2346

[ad_1] NASA's Hubble Telescope has once again captivated space enthusiasts with a stunning image showcasing the "last gasp" of a dying binary star system known as NGC 2346. This system, classified as a "planetary nebula," emerges from Sun-like stars that are approaching the final stages of their life cycles.What NASA says about NGC 2346The image, shared by NASA on Instagram offers a mesmerizing glimpse into NGC 2346, located about 2,000 light-years away in the constellation Monoceros. Planetary nebulae like this are formed when Sun-like stars reach the final stages of their life cycles and eject their outer layers into space. What makes NGC 2346 particularly fascinating is its central binary star system, where two stars orbit each other in a tight 16-day cycle. The evolutionary journey ...

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...

NASA’s Hubble Telescope snaps RARE Lenticular galaxy

[ad_1] Despite decades of service and the launch of the latest James Webb Space Telescope, the Hubble Space Telescope has not stopped surprising scientists with its cosmic revelations. Recently, NASA's Hubble Telescope shared an image of lenticular galaxy NGC 5283. It contains an active galactic nucleus (AGN), which is an extremely bright region at the heart of a galaxy where a supermassive black hole exists. As matter falls into a black hole, it produces a release of energy that emits light throughout the electromagnetic spectrum due to the heating of the dust and gas.What is a Lenticular galaxy? NASA says that it possesses characteristics of both spiral and elliptical galaxies. They share the central bulge and disk features of spiral galaxies, but they lack the spiral arms. Similar to...

NASA Astronomy Picture of the Day 22 April 2023: Hubble Telescope snaps amazing Stellar Nursery

[ad_1] NASA is sharing a jaw-dropping view of the Stellar Nursery which is seen as a reflection nebula. A reflection nebula forms when a nearby dust cloud scatters or reflects the light from a star. This scattered light is polarized to a small extent and exhibits a spectrum resembling that of the illuminating star but with a bluer hue. NASA says that just "like fog around a street lamp, a reflection nebula shines only because the light from an embedded source illuminates its dust; the nebula does not emit any visible light of its own."NASA's Explanation for Astronomy Picture of the DayWhile sharing the image, NASA has explained about the nebula, "In visible light, NGC 1333 is seen as a reflection nebula, dominated by bluish hues characteristic of starlight reflected by interstellar dust...

Webb Space Telescope spots early galaxies hidden from Hubble Space Telescope

[ad_1] NASA's Webb Space Telescope is finding bright, early galaxies that until now were hidden from view. NASA's Webb Space Telescope is finding bright, early galaxies that until now were hidden from view, including one that may have formed a mere 350 million (35 crore) years after the cosmic-creating Big Bang.Astronomers said on Thursday that if the results are verified, this newly-discovered throng of stars would beat the most distant galaxy identified by the Hubble Space Telescope, a record-holder that formed 400 million (40 crore) years after the universe began. Launched last December as a successor to Hubble, the Webb telescope is indicating stars may have formed sooner than previously thought -- perhaps within a couple million years of creation. Webb's latest discoveries were d...
