NASA’s James Webb Space Telescope Set For Blastoff To Study Universe’s Origin
NASA’s $10 billion telescope, the James Webb Space Telescope, is designed to capture the first glimpse of the universe shortly after the Big Bang. The target is at the European Space Agency’s French Guiana Kourou on Saturday, December 25 at 7:20 am Launched from the European Space Agency’s Kuru launch site on Christmas Day. In the next ten years, this revolutionary world’s first space science observatory will capture the earliest galaxies believed to have formed during the formation of the early universe. The new telescope will help scientists probe the structure and origin of our universe and our position in it. But after launching, Weber will deploy a sun visor the size of a tennis court, which will block MIRI and other instruments from the heat of the sun and allow them to passively cool down. Starting approximately 77 days after launch, MIRI’s cryogenic cooler will take 19 days to reduce the temperature of the instrument’s detector below 7 Kelvin. Penanen explained that for the space observatory, a physically compact, energy-efficient cooler instrument is needed. It must be highly reliable because we cannot go out and repair it. “So these are the challenges we face. In this regard, I would like to say that the MIRI cryogenic cooler is definitely at the forefront.” The 7.2-ton James Webb Space Telescope [JWST] will be launched from Northeast South America on the Ariane 5 rocket. The coast launch is designed to capture starlight from the first galaxies and will be the largest telescope ever put into orbit by NASA. One of Weber’s scientific goals will be to study the properties of the first generation of stars that formed in the universe. Weber’s near-infrared camera or NIRCam instrument will be able to detect these extremely distant objects, and MIRI will help scientists confirm that NASA explained that these faint light sources are clusters of first-generation stars, rather than forming as galaxies evolve Of the second generation of stars.

Nasa’s old map of Jupiter, which reminds many of dosa, has gone viral once more
Certain images or videos frequently resurface on the Internet, leaving people speechless. When those clips or pictures are shared again on one social media platform or another, they create a buzz. The National Aeronautics and Space Administration (Nasa) created and posted this image of a map of Jupiter online a few years ago. After being shared on Twitter, the image drew a lot of attention this time. And, as usual, the image made people think of dosa, a popular South Indian dish.
The image was shared by the Twitter account Latest in Space. “From the very bottom of Jupiter, I’m looking up. While tweeting the image, they wrote, “Seen by NASA Cassini.” The images from the Cassini spacecraft’s narrow-angle camera were used to create this out-of-this-world image, which is part of a coloured map series produced by the space agency.
The article was published a few days ago. The tweet has received nearly 20,000 likes since it was shared, and the number is growing. The tweet has been retweeted more than 2,000 times. Take a look at some of the comments to see how the image of Jupiter looks like dosa.
A Twitter user commented, “Looks like a designer dosa.” “When I rush to pick up a call, this is what happens to my dosa on the dosa pan,” one joked. “This is how my mother makes Dosa,” a third said. “Jupiter in the making,” wrote a fourth, along with a photo of someone preparing – you guessed it – dosa.
