On Dec. 25, 2021, NASA's James Webb Space Telescope launched into space to peer farther back into the universe's history than ever before.
The Webb space telescope launched off planet Earth at 7:20 a.m. EST (1220 GMT) atop an Ariane 5 rocket built by Arianespace. The space telescope, NASA's biggest ever built, is headed to L2, or Lagrange Point 2, a stable point in space about 1 million miles from Earth where it will look for the first stars and galaxies in the universe.

The James Webb Space Telescope is a $10 billion infrared observatory designed to explore the universe in infrared light.
Scientists hope it will help them unravel the mysteries of how the first stars formed, seek out dark matter mysteries and peer pack more than 13 billion years in time to the earliest days of the universe.
To do this, the space telescope will observe the universe at the L2 point and use a novel sunshield the size of tennis court to keep it ultracold - minus 370 degrees Fahrenheit - in order to detect the earliest light in the cosmos.
But first, James Webb Space Telescope had to leave Earth behind and to do that, it had to get to its launch site.
Here is the cargo ship carrying NASA's James Webb Space Telescope that arrived in French Guiana on Oct. 12, 2021, after a 16-day sea voyage. The space telescope is so large that it could not fit inside the payload fairings of most U.S. rockets, so NASA and its European Space Agency partners (among others) picked Arianespace's Ariane 5 heavy-lift rocket to carry the observatory.
Ariane 5 rockets launch from Europe's Guiana Space Center in Kourou, French Guiana in South America, so the Webb space telescope was shipped by cargo ship to the site with some secrecy, as the mission team was concerned about pirates.

The Christmas launch was both celebrated and a challenge for Arianespace, NASA and other mission partners. With the launch originating from French Guiana, international travel restrictions from the coronavirus pandemic limited the amount of people able to travel for the launch.
The moment of ignition for the Ariane 5 rocket carrying the James Webb Space Telescope is captured here in a NASA TV video still.
The Ariane 5 rocket generated 2.6 million pounds (1,200 tons) of thrust at liftoff with its main stage and two strap-on boosters. It took 27 minutes to fully deploy the space telescope into space.
The Ariane 5 carrying the James Webb Space Telescope soared through some cloudy skies when it launched off the Earth.
Those clouds posed no problem for the launch, even though bad weather delayed the launch from a Christmas Eve liftoff to Christmas Day.
"Don't let those clouds fool you, we are go for launch," NASA's Rob Navias said before liftoff.

"Today's countdown was as flawless as you can imagine," NASA spokesperson Rob Navias said after liftoff. "Everything fell together on this Christmas Day to send a new present to the world's astronomers."

The space center is the primary spaceport for the European Space Agency and other European countries and is the home port for the Ariane 5 rocket. Arianespace also launches Russian-built Soyuz rockets from the spaceport.
