#JamesWebbSpaceTelescope's new photo of the Tarantula Nebula caught thousands of never-before-seen baby stars

Astronomers focused the #JamesWebbSpaceTelescope on Tarantula Nebula, one of the brightest and most active star-forming regions in our galactic backyard, and found thousands of young stars they hadn't seen before, images released by NASA on Tuesday show.

The Tarantula Nebula, is an immense cloud of gas and dust about 160,000 light-years away in the Large Magellanic Cloud, a satellite galaxy of the #MilkyWay. The nebula has birthed some massive stars, a few that are more than 150 times the mass of our sun.

To find out more about this stellar birthplace, astronomers trained three of #Webb's high-resolution infrared instruments on it. By gathering infrared light, the telescope is able to cut through cosmic gas and dust, penetrating deeper into the cosmos.

#Webb's new image of the nebula taken with the Near-Infrared Camera (NIRCam), above, shows strands of gas that look like spider webs, "a burrowing tarantula's home, lined with its silk," according to @NASA.

The image shows distant galaxies in the background that look like fuzzy white dots. A cluster of massive young stars can be seen at the center of the image in sparkling blue. The space around the young stars is where gas has been cleared out by the stars' intense radiation.

Astronomers looked at the same region in longer infrared wavelengths detected by #Webb's Mid-Infrared Instrument (MIRI). In the right image below, "the hot stars fade, and the cooler gas and dust glow," NASA said.

Using #Webb's Near-Infrared Spectrograph, astronomers also caught an emerging star being released from a cocoon of dust. When nascent stars form inside nebula, they are surrounded by cocoon-like pillars of gas and dust, which block visible light.

#Brahmastra wipes out over ₹800 crore wealth of PVR and Inox #investors

businessinsider.in/stock-market/n…

By @jainrounak

Forget making back money, it looks like Brahmastra is taking down PVR & Inox investors with itself. With early reviews pouring cold water on #Brahmastra’s prospects, India’s largest theater chains PVR & Inox have cumulatively lost over ₹800 crore in market capitalization today.

In Indian mythology, #Brahmastra is known as a weapon of unstoppable destruction, which can only be stopped by its counterattack astra (weapon). Ironically, the movie could end up being a victim of the weapon it is named after.

Britain's longest-reigning monarch #QueenElizabethII died on Thursday at England’s Balmoral at the age of 96.

The Queen ruled Britain for 70 years following her father King George VI’s sudden death in 1953.

#QueenElizabeth

The late #QueenElizabethII has visited India three times – in 1961, 1983 and 1997, each time accompanied by her husband and Duke of Edinburgh, the late Prince Philip. Her first visit came nearly 15 years after India's independence.

From coins, notes to national anthem, here's how #KingCharlesIII will replace #QueenElizabethII

By @jainrounak

#KingCharlesIII takes over as the British monarch after the death of #QueenElizabethII, and that will lead to a demonetisation in the UK. New coins and currency notes will be minted and printed after the designs are approved.

#QueenElizabeth

The death of #QueenElizabethII has given the British monarchy its first King after over 70 years. The old coins and notes will be slowly phased out of circulation.

The old coins and notes featuring #QueenElizabeth II will continue to be legal tender for the time being.

#NASA's James Webb Space Telescope detects carbon dioxide in a distant world's atmosphere for the first time

#JamesWebbSpaceTelescope

businessinsider.in/science/news/n…

NASA's #JamesWebbSpaceTelescope have detected evidence of carbon dioxide in a world beyond our solar system.

The planet, called WASP-39 b, is a gas giant orbiting a sun-like star about 700 light-years away, where temperatures are consistently about 900 degrees Celsius.

#NASA

While the planet was first discovered in 2011, Webb's sensitive infrared instruments allowed researchers to analyze it in detail, definitely detecting carbon dioxide there for the first time.
