And yet, it would take 60,000 years to get there. (estimates vary depending on technology used). In other words... forgedaboudit we ain't sending peoples there Perhaps not in our lifetime, but less than 100 years ago the idea of sending humans to the Moon would have also seemed impossible. With the right discoveries and technological advancements, visiting Proxima Centauri will almost certainly be possible in the not-too-distant future.

But even if we learn to fly at near the speed of light, it will still take us 100,000 years to cross our own galaxy. So, our technological advancements better be in the realm of the exotic wormhole or even interdimensional travel, otherwise, we'll never make such a journey. It's still nice to dream, though :-) Link to comment Share on other sites More sharing options...

Still Waters Posted August 2, 2022 #30 Share Posted August 2, 2022 (IP: Staff) · Webb Captures Stellar Gymnastics in The Cartwheel Galaxy NASA’s James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy’s central black hole. Webb’s powerful infrared gaze produced this detailed image of the Cartwheel and two smaller companion galaxies against a backdrop of many other galaxies. This image provides a new view of how the Cartwheel Galaxy has changed over billions of years. The Cartwheel Galaxy, located about 500 million light-years away in the Sculptor constellation, is a rare sight. Its appearance, much like that of the wheel of a wagon, is the result of an intense event – a high-speed collision between a large spiral galaxy and a smaller galaxy not visible in this image. Collisions of galactic proportions cause a cascade of different, smaller events between the galaxies involved; the Cartwheel is no exception. https://www.nasa.gov/feature/goddard/2022/webb-captures-stellar-gymnastics-in-the-cartwheel-galaxy Link to comment Share on other sites More sharing options...
jethrofloyd Posted August 26, 2022 #31 Share Posted August 26, 2022 The James Webb telescope recorded CO2 in the atmosphere of an extrasolar planet for the first time NASA’s James Webb Space Telescope (JWST) has spotted carbon dioxide in the atmosphere of a planet 700 light years away called WASP-39b. This is the first time the compound has been found in any exoplanet, and the observations also revealed hints of a mystery within the distant world. WASP-39b is huge. It has a mass similar to Saturn’s, and a diameter 1.3 times that of Jupiter. It orbits relatively close to its star, giving it an average temperature around 900°C – the high temperature puffs up the atmosphere, making it easier for JWST to see starlight shining through it. https://www.newscientist.com/article/2335371-jwst-found-carbon-dioxide-in-an-exoplanet-atmosphere-and-a-mystery/ Link to comment Share on other sites More sharing options...
