The James Webb Space Telescope was launched successfully

It’s a moment that’s been a long time coming. On Christmas morning, NASA’s top space observatory for the next decade, the James Webb Space Telescope, was safely launched.

At 7:20 a.m., the telescope launched atop an Ariane 5 rocket from Europe’s Spaceport in French Guiana. ET.
NASA tweeted, “We had LIFTOFF of the @NASAWebb Space Telescope!” “The beginning of a new, thrilling decade of research soared to the sky at 7:20 a.m. ET (12:20 a.m. UTC), with Webb’s goal to #UnfoldTheUniverse changing our understanding of space as we know it.”\


The Webb telescope has endured years of delays, including a combination of factors brought on by the pandemic and technical challenges. But the world’s most powerful and complex space observatory will answer questions about our solar system, study exoplanets in new ways and look deeper into the universe than we’ve ever been able to.
The European Space Agency aptly referred to it as “an awesome Christmas present” for the international launch teams, as well as the whole of space science, on Twitter. NASA Administrator Bill Nelson shared his gratitude for the international teams that made the mission and the Christmas Day launch possible. “This is a great day for planet Earth,” Nelson said shortly after the launch. “Thanks to the team. You all have just been incredible. Over three decades, you produced this telescope that is now going to take us back to the very beginnings of the universe. We are going to discover incredible things that we never imagined.”

Webb will peer into the very atmospheres of exoplanets, some of which are potentially habitable, and it could uncover clues in the ongoing search for life outside of Earth. The telescope comes equipped with a mirror that can extend 21 feet and 4 inches (6.5 meters) — a massive length that will allow the mirror to collect more light from the objects it observes once the telescope is in space. The more light the mirror can collect, the more details the telescope can observe. The mirror includes 18 hexagonal gold-coated segments, each 4.3 feet (1.32 meters) in diameter. It’s the largest mirror NASA has ever built, the agency said, but its size created a unique problem. The mirror was so large that it couldn’t fit inside a rocket. So the NASA team designed the telescope as a series of moving parts that can fold origami-style and fit inside a 16-foot (5-meter) space for launch.
Webb will act as an infrared detective, detecting light that is invisible to us and revealing otherwise hidden regions of space, according to NASA.

Since 2004, thousands of scientists, technicians and engineers from 14 countries have spent 40 million hours building the telescope. The telescope includes instruments from the Canadian Space Agency and the European Space Agency. Now, Webb is ready to help us understand the origins of the universe and begin to answer key questions about our existence, such as where we came from and if we’re alone in the cosmos.

What Webb will see
The Webb telescope will look at every phase of cosmic history, including the first glows after the big bang that created our universe and the formation of the galaxies, stars and planets that fill it today. Its capabilities will enable the observatory to answer questions about our own solar system and investigate faint signals from the first galaxies formed 13.5 billion years ago.

The telescope will take a closer look at a selection of exoplanets to peer inside their atmospheres, if they have them, and help answer questions about how the planets formed and evolved. Data collected by the telescope can tell scientists if methane, carbon dioxide or carbon monoxide is in the atmosphere. The gases within these alien atmospheres could reveal the very building blocks of life. Other objects of interest for the initial science campaign include observing the supermassive black hole at the center of the Milky Way, actively forming planetary systems, bright quasars at the center of galaxies, and leftovers from the formation of our solar system known as Kuiper Belt Objects.
