Washington: The cosmic cliffs of the star nursery, the quintet of galaxies tied to the dance of celestial bodies: The James Webb Space Telescope released the next wave of images on Tuesday, heralding a new era of astronomy.
Webb also revealed the details of Stephan’s Quintet as something he had never seen before. This is a group of five galaxies, including four that experience repeated close encounters, providing insights into how the early galaxies were formed at the beginning of the universe.
The telescope dramatically captures the shock wave as one of the galaxies breaks through the center of the cluster.
The dim star in the center of the Southern Ring Nebula was revealed to be dust-covered for the first time as it spewed a ring of gas and dust in its death tragedy.
Understanding the molecules that exist in such stellar graveyards can help scientists learn more about the process of stellar death.
The telescope has also found water vapor in the atmosphere of distant gas giants. Spectroscopy (analysis of light revealing detailed information) was from the planet WASP-96b, which was discovered in 2014.
About 1,150 light-years away from Earth, WASP-96b weighs about half the mass of Jupiter and zips around it in just 3.4 days.
“We’ve seen what happens when a planet and its atmosphere pass in front of a star and the star’s light passes through the atmosphere. We can break it down into wavelengths of light,” NASA’s Knicole Colon. Mr. says.
“So you’re actually seeing uplifts and wiggles that indicate the presence of water vapor in the planet’s atmosphere.”
Launched by the Ariane 5 rocket from French Guiana in December 2021, the Webb is orbiting the Sun in a region of space called the Second Lagrange Point, at a distance of 1 million miles (1.6 million kilometers) from Earth. ..
Here, it remains fixed with respect to the Earth and the Sun, minimizing the fuel required to correct the course.
The total cost of the engineering wonder project is estimated at $ 10 billion, making it one of the most expensive scientific platforms ever built, comparable to CERN’s Large Hadron Collider. ..
Webb’s primary mirrors are over 21 feet (6.5 meters) wide and consist of 18 gold-coated mirror segments. Like a camera in your hand, the structure needs to be as stable as possible to get the best shots.
After the first image, projects are competitively selected through a process in which applicants and choosers do not know each other’s identities in order for astronomers around the world to share time with the telescope and minimize bias. ..
Thanks to its efficient launch, NASA estimates that Webb has enough propellant for a 20-year lifespan to answer basic space questions in collaboration with the Hubble Space Telescope and the Spitzer Space Telescope. increase.
