The James Webb Space Telescope (JWST) was launched from the French Guiana launch site at 7:21 a.m. on Dec 25, 2021. The Arianespace Ariane 5 rocket is scheduled to lift off at 9:20 a.m. local time.
The James Webb Space Telescope will be the most powerful space telescope in the world and it will be used to investigate the history of the universe. It is one of NASA's Great Observations, huge space instruments that include the likes of the Hubble Space Telescope.
Key facts about the James Webb Space Telescope.
The launch date is December 25, 2021.
At the time of launch, the cost was $10 billion.
The sun will be around 1 million miles from Earth.
The primary mirror is 21.3 feet across.
The sun shield is 22 meters by 12 meters.
The mass is 14,300 lbs.
It took 30 days for the James Webb Space Telescope to reach its permanent home, which is a Lagrange point. The second sun-Earth lagrange point was L2 on January 24, 2022. The telescope will be able to stay in line with Earth as it travels through L2 because it lies opposite of the sun. It is a popular spot for several other space telescopes.
There are pictures of the James Webb Space Telescope.
According to NASA, the James Webb Space Telescope will focus on four main areas: first light in the universe, assembly of galaxies in the early universe, birth of stars and protoplanetary systems, and planets.
The telescope is undergoing a series of science and calibration tests. The Space Telescope Science Institute says that the best images from JWST will appear about six months after launch.
The Hubble Space Telescope is expected to take amazing photos of objects in the sky. The Hubble Space Telescope is in good shape and it is likely that the two telescopes will work together for the first few years. There are exoplanets that the Kepler Space Telescope found, or follow up on real-time observations from ground space telescopes.
The European Space Agency, the Canadian Space Agency, and NASA collaborated to create the James Webb Space Telescope. Over 300 universities, organizations and companies were involved in the project. The goal is 10 years, but the nominal duration is five years.

The James Webb Space Telescope was launched from the European Space Agency&s launch site in French Guiana at 7:21 a.m. The Arianespace Ariane 5 rocket is scheduled to lift off at 9:20 a.m. local time.
Thanks to a successful and precise launch, NASA announced that the JWST should have enough fuel to double its mission life expectancy. The James Webb Space Telescope has accomplished a lot since it was launched.
What is the location of the James Webb Space Telescope?
You can keep track of what is happening with the deployment of the telescope with NASA.
The observatory flew away from the Ariane 5 rocket that carried it into space. The video shows the rocket stage drifting away and the solar panels unfurling. This is the last view we will ever see of the James Webb Space Telescope, as the observatory doesn't have any cameras onboard.
According to a NASA statement, it took about one hour to deploy and test a key antenna for the James Webb Space Telescope. Twice daily science data dumps will be responsible for the antenna. The observatory sailed beyond the moon on December 27.
On December 31, 2021, the sun shield was unfurled. The tensioning of the sun shield began on January 3. On the next day, it was completed. The secondary mirror was latched on Jan. 5, 2022, after it was successfully deployed.
Then on Jan. 8. The giant primary mirror has been fully deployed, according to NASA. The alignment of the 18 individual mirrors that make up the observatory's primary mirror is the next step. It could take up to 120 days for the alignment to be complete, according to NASA.
L2 is the second sun-Earth lagrange point and will be the final destination for the James Webb Space Telescope. After traveling over a million miles. In space, lagrange points are stable.
On Feb, 11. The first images of starlight were captured by the James Webb Space Telescope. The first image taken was of a star. A mosaic of 18 bright dots was created by the light from HD84406 being captured by 18 mirror segments located on the primary mirror.
The 18 dots will slowly become a single star over the next few months, according to Thomas Zurbuchen, NASA's Associate Administrator for the Science Mission Directorate.
On Feb. 18. A new and improved image of HD84406 shows 18 unfocused copies of a star in a hexagonal formation. The image stacking process will begin once the individual segments of the primary mirror are aligned. This will allow for a clear view of 18 images on top of each other.
A specialized camera inside the NIRCam instrument has been used to take an impressive selfies by the man. The camera is designed to be used.
One of the mirror segments is shining brighter than the others, this is because it is the only segment at the time that successfully aligned and pointed at a star. One by one, the rest of the mirror segments were aligned.
On April 28, NASA announced in a statement that the James Webb Space Telescope had finished its alignment phase after demonstrating it can capture crisp, well focused images.
The next phase of work will include telescope calibration.
The science mandate is divided into four areas.
First light and reionization.
This refers to the early stages of the universe after the Big bang. The universe was a sea of particles and light was not visible until the universe cooled enough for these particles to combine. The epoch of reionization is when neutral hydrogen was reionized by radiation from the first stars.
There is an assembly of galaxies.
It's a good way to see how matter is organized on huge scales, which in turn gives us clues as to how the universe evolved. The spiral and elliptical galaxies we see today evolved from different shapes over billions of years, and one of the goals of the JWST is to understand that evolution. Scientists are trying to figure out how we got the variety of galaxies that are visible today.
Birth of planets and stars.
The Pillars of Creation are some of the most famous birthplaces for stars. As the stars grow, the radiation pressure they exert blows away the gas in the clouds, which could be used again for other stars. It is difficult to see inside the gas. The stars that are being born in these cocoons will be able to be seen by the eyes of the JWST.
There are planets and the beginnings of life.
The last decade has seen a lot of exoplanet discoveries. In some cases, the atmospheres of these planets will be imaged by the powerful sensors of the JWST. Understanding the atmospheres and the formation conditions for planets could help scientists better predict if certain planets are in or out of the water.
Four science instruments will allow for observations in the visible, near-IR and mid-IR wavelengths.
The successor to the Hubble Space Telescope is referred to as the James Webb Space Telescope.
Scientific advancement is all about standing on the shoulders of giants, and the JWST will do just that, as its scientific goals were motivated by the results from Hubble.
Hubble primarily observed the cosmos in optical and ultraviolet wavelengths, whilst the two space telescopes have different capabilities. The universe will be looked at by the JWST. The expansion of the universe causes light from distant objects to shift to longer wavelength at the red end of the spectrum. Some of the oldest stars and galaxies in the universe will be revealed by the JWST.
The difference between the Hubble Space Telescope and the James Webb Space Telescope is that Hubble is able to see the sun. Hubble was accessed and serviced by space shuttle missions.
Good things come to those who wait.
Astronomers have been testing their patience since the first planned fly in 2007. A mix of engineering problems, political hesitancy and project management issues have all contributed to countless delays.
In July of 2011, politicians in the U.S. threatened to pull funding for the JWST. The spacecraft was saved in November 2011. The launch of the JWST was delayed due to technical issues. The launch was recommended to be moved to March 2021.
In 2020, The global coronaviruses impacted the progress of the JWST and in July 2020, NASA announced a new launch date. The delays kept coming despite the perseverance and determination of the team.
Problems with the Ariane 5 launch vehicle pushed the launch date back to November or early December of 2021. In September NASA and the European Space Agency announced that the observatory had not yet been shipped from its original location in California to the launch site in French Guiana. The two agencies announced a new launch date, but bad weather stopped that from happening.
The JWST was successfully launched from the launch site in French Guiana at 7:21 a.m. on Dec 25, 2021. The Arianespace Ariane 5 rocket is scheduled to lift off at 9:20 a.m. local time.
The Next Generation Space Telescope was renamed the James Webb Space Telescope in 2002.
The former NASA chief is the subject of the JWST. The first man on the moon was just a few months after the retirement of the space agency's leader.
Although he is most associated with the Apollo moon program, he is also considered a leader in space science. Even in a time of great political turmoil, NASA's science objectives were set by the agency's director.
More than 75 space science missions were launched by NASA. They included missions that studied the sun, stars, and galaxies as well as space directly above Earth's atmosphere.
Some people are not happy with the name of the telescope. Critics started an online petition urging NASA to change the name of the telescope due to claims that it was used to discriminate against gay and lesbian NASA employees. NASA will not change the telescope's name despite complaints.
You can learn how the JWST is designed to answer some of the biggest questions in the universe with the UK Space Agency and explore it with NASA. There are fun facts and a folding puzzler to keep you entertained.
