❄️ Season’s Greetings ❄️

The Snowman Nebula ☃️ is an emission nebula that resides in the constellation Puppis in the southern sky, about 6,000 light-years away from Earth.
Emission nebulae are diffuse clouds of gas that have become so charged by the energy of nearby massive stars that they glow with their own light. The radiation from these massive stars strips electrons from the nebula’s hydrogen atoms in a process called ionization.
As the energized electrons revert from their higher-energy state to a lower-energy state, they emit energy in the form of light, causing the nebula’s gas to glow.

The remarkable image shows Comet C/2021 A1, commonly known as Comet Leonard ☄️, which was first discovered in 3rd January 2021 by astronomer Greg Leonard.
It made its closest pass on 12th December 2021.
On 25 December 2021, Gerald Rhemann captured a dramatic moment in the life of a comet: a disconnection event.
This happens when a piece of the comet's tail becomes separated after being hit by high velocity solar particles.
However, the comet won’t be seen from Earth ever again, which makes his photo all the more remarkable✨!

New James Webb Space Telescope images, released Monday, captured the most detailed and sharpest images ever taken of the Orion Nebula.
The Orion Nebula is a massive star-forming region 1,350 light-years from Earth, making it the nearest stellar nursery to us. Dense clouds of cosmic dust in the nebula obscure star-forming structures from instruments that rely on visible light, like the Hubble Space Telescope. By gathering infrared light, Webb is able to peer through those layers of dust, giving astronomers unprecedented views of the nebula's various components.
Young, newly-forming stars nestle inside dense cocoons of cold gas and dust, which are difficult to see in visible light. Webb, however, is so sensitive to infrared light it would be able to detect the heat of a bumblebee on Earth from as far away as the moon.
In the new images, Webb was able to capture a star forming inside a cocoon of gas, which isn't visible in Hubble's images of the nebula.
The Orion Nebula is home to a massive group of stars called the Trapezium Cluster. This group of young stars emits intense ultraviolet radiation, shaping the surrounding cloud of dust and gas.
The Orion Nebula is similar to the environment our solar system was born in, so studying it could be key to understanding our solar system.

When Generations Meet! 🌟🔭

M74 or NGC 628 or Phantom Galaxy is one of the most spectacular galaxies visible from Earth.

Situated some 32 million light-years away from Earth, in the constellation Pisces, it is known for its well-defined spiral shape with prominent arms emanating from its center.

While the 32-year-old Hubble Space Telescope captures the universe mostly in the visible light spectrum, revealing the distribution of stars in the galaxy, Webb focuses on the infrared spectrum, spotting heat-emitting gas and dust that accumulates in the galaxy's spiral arms.

Hubble's image is in ultraviolet and optical wavelengths. It shows thick, dark, ropy regions that are dense with dust and bursts of red. These are huge clouds of hydrogen gas that are glowing brightly in ultraviolet, the result of intense flurries of star formation.

What Hubble can't do very well is pe*****te deeper into the dust and gas to obtain more detail about those recent episodes of star formation. This is where JWST comes into play with its its sensitive and powerful infrared capabilities.

Infrared radiation has a longer wavelength than visible or infrared light, which at shorter wavelengths is scattered more easily by small particles. This means infrared light can pass relatively unobscured through dusty, cloudy regions; if you can see in infrared, as we can with JWST, you can see things you wouldn't be able to see in shorter wavelengths.

When combined, observations by the two great space telescopes provide a comprehensive view of the galaxy including regions in which stars form that can be seen as reddish bubbles scattered across the spiral arms.

History has been made!

NASA releases James Webb Telescopes’s first fully colored image of SMACS 0723 galaxy cluster located 4.6 billions light years away from us.

This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.

This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks.

The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it which are around 13 billion light years away.

For reference, our universe is 13.8 billion years old.

NASA releases first “Fully Aligned” image from James Webb Space Telescope
“WE HAVE THE HIGHEST RESOLUTION INFRARED IMAGES TAKEN FROM SPACE EVER,
said Scott Acton, wavefront sensing and controls scientist working on JWST.
While the purpose of this image was to focus on the bright star at the center for alignment evaluation, Webb's optics and NIRCam are so sensitive that the galaxies and stars seen in the background show up. At this stage of Webb’s mirror alignment, known as “fine phasing,” the telescope perfectly aligned its 18 hexagonal mirror segments to focus on a single bright star.
This image of the star, which is called 2MASS J17554042+6551277, uses a red filter to optimize visual contrast.
Scientists are now hoping to complete the last steps of the alignment process before preparing the JSWT’s scientific instruments.
Despite the big success, official operations won’t kick off for another couple of months — but the excitement is certainly palpable.

Tonga’s Hunga Tonga Volcano had one of the most violent volcano eruptions ever captured on satellite..🌋🛰
Tonga undersea volcano eruptions released upto 18 megatons of energy. Thats about 1200 times more powerful than the atomic bomb US dropped on Hiroshima in 1945.

The undersea volcano had been burbling since late December 2021, shaking the seas near Tonga with a series of outbursts. Things kicked into higher gear this month, with powerful blasts on Jan. 13 and Jan. 14 and then an even bigger eruption on Jan. 15 that sent ash and dust 25 miles (40 kilometers) into the Pacific sky.
