TAMPA, Fla. (WFLA) — NASA launched the James Webb Space Telescope on Saturday, Dec. 25 aboard the Ariane 5 rocket.

NASA said the telescope, which is 100 times more powerful than the Hubble telescope, is designed to “solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it.”

According to NASA.gov, Webb will capture the universe’s first stars and galaxies from light stretched over space and time.

“Once the spacecraft has fully unfolded in space and begun collecting data, it will provide an unprecedented window into our universe’s deep past.”

The spacecraft and its payload arrived at the Arianespace ELA-3 launch complex Thursday afternoon at Europe’s Spaceport located near Kourou, French Guiana where it will stand on planet Earth for its last time.

Webb is scheduled for liftoff at 7:20 am EST Saturday, Dec. 25.

Before the launch, teams will power on the observatory while at the launch pad to run one final aliveness test and ensure all systems have power and are working properly.
