NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.
Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. 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.
An angular size doesn't depend on where you're standing.[quoting nasa.gov!] "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."
Nor do most people, including at news outlets, which commonly say it's "a million miles above the earth". No one even makes an effort at science education today, so let's just look at some pretty pictures (which many will think are just like Hubble all over again but more expensive).After a news item yesterday on the James Webb telescope I didn't understand its orbit.
The world is so full of cynicism and irrationality today that people forget all about that. A dose of awe is in order.After the first picture became available yesterday I circulated it to a few friends and relatives describing the JWT as the greates accomplishment of humankind. There is nothing so pure and innocent as the search for knowledge.
Saw this last night, stunning picture and interesting how the galaxy formed.The latest image from the James Webb Space Telescope shows the Cartwheel galaxy, a ring galaxy located 500 million light-years away that formed when a large spiral galaxy and a small galaxy violently collided.
