These Are the James Webb Space Telescope’s Most Scientifically Glorious Discoveries of 2023

• No. 1 Cosmic Headaches:
• No. 2 Water, Water Everywhere.
• No. 3 Young Carbon.
• No. 4 That’s a Big Black Hole.
• No. 5 Charlotte’s Cosmic Web.
• No. 6 Jumping Jupiter Jet Streams.
• No. 7 Supernova Hat Trick.

Here are some of the James Webb Space Telescope’s discoveries in 2023: 

• Supermassive black hole The telescope discovered the most distant supermassive black hole, which is estimated to be 90 million times the mass of the sun. It formed 570 million years after the big bang. 
• Jupiter-sized planets In September 2023, the telescope discovered over 80 pairs of Jupiter-sized planets in the Orion Nebula. 
• Star-forming region In July 2023, the telescope released a close-up image of the nearest star-forming region to Earth. The region is 390 light-years away, allowing the telescope to capture highly detailed images. 
• New galaxies The telescope discovered hundreds of new galaxies, many of which are from the early universe. 
• Evidence of ice on Mars NASA found evidence of ice on Mars. 

The telescope also took many stunning photos in 2023, including: 

• HH 211 
• Rho Ophiuchi 
• Uranus 
• The Crab Nebula 
• The Orion Bar

The James Webb Space Telescope has made many discoveries, including: 

• Carbon In 2023, astronomers using the telescope detected carbon in a galaxy that existed just one billion years after the Big Bang. 
• Planetary atmospheres The telescope can gather information about the atmospheres of planets orbiting stars hundreds of light-years away. 
• Jupiter’s atmosphere In 2023, the telescope discovered a new feature in Jupiter’s atmosphere: a high-speed jet stream that spans more than 3,000 miles wide. 
• Exoplanets In January 2023, the telescope discovered its first exoplanet, LHS 475 b. The planet is almost the same size as Earth, but a few hundred degrees warmer. 

The telescope has also taken detailed images of galaxies that existed when the universe was only 900 million years old. These galaxies are clumpy, often elongated, and are actively forming stars.

In August 2023, the James Webb Space Telescope (JWST) captured an image of Earendel, the most distant star ever detected. The star is 28 billion light-years away and appears as a reddish dot in the Sunrise Arc galaxy. The starlight the JWST captured was produced in the first billion years of the universe’s 13.8 billion year history

The JWST has also spotted the most distant galaxy cluster ever found, which is nearly 30 billion light years away. Scientists have also used the JWST to find the second and fourth most distant galaxies ever discovered, which are around 33 billion light-years away

The James Webb Space Telescope (JWST) can see 13.6 billion light yearsaway, which is the farthest we’ve ever seen into space. A single light year is just under 6 trillion miles

The JWST can see light from over 13 billion light years in the past, located in galaxies that are currently around 33 billion light years away. It can see what the universe looked like around a quarter of a billion years after the Big Bang, when the first stars and galaxies started to form. 

The JWST can see further than the Hubble Space Telescope because it is in the infrared. Its high-resolution and high-sensitivity instruments allow it to view objects too old, distant, or faint for the Hubble Space Telescope.

Yes, the James Webb Space Telescope (JWST) can observe planets beyond the orbit of Mars, as well as satellites, comets, asteroids, and Kuiper belt objects. The telescope can also monitor the weather of planets and their moons

In September 2022, the JWST took the first-ever direct image of a planet outside our solar system. The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable. 

The JWST also observed the exoplanet K2-18 b, which is 8.6 times the size of Earth. The telescope discovered the presence of methane and carbon dioxide on the planet, which indicates it could be a Hycean exoplanet that might be able to support life. 

The JWST can also detect faint chemical signatures in light coming from exoplanets. In the coming months, the telescope is set to turn its mirrors toward TRAPPIST-1e, a potentially habitable Earth-sized planet 39 light-years from Earth.

Yes, the James Webb Space Telescope (JWST) has detected water on a distant planet

the JWST detected water, clouds, and haze in the atmosphere of a hot gas giant planet called WASP-96 b. The planet orbits a star similar to our Sun, over a thousand light years away.

In 2023, the JWST detected water vapor in the PDS 70 star system. The water vapor was detected in a region less than 100 million miles from the star, where rocky planets may be forming. 

In November 2023, astronomers used the JWST to study the atmosphere of the exoplanet WASP-107b. They found water vapor, sulfur dioxide, and silicate sand clouds in the planet’s atmosphere. 

The JWST has also detected methane and carbon dioxide on the planet K2-18b. These findings suggest the presence of a water ocean beneath a hydrogen-rich atmosphere. 

The JWST’s detection of water vapor and other gases on distant planets could be a breakthrough for exoplanet research. It could help scientists search for other worlds that could support life.
