Nasa’s James Webb telescope fully deployed in space, ready to study every phase of cosmic history
- The most powerful space telescope ever built and the successor to Hubble, Webb is heading to its orbital point, a million miles (1.5 million km) from Earth
- Webb’s infrared technology allows it to see the first stars and galaxies that formed 13.5 billion years ago
The James Webb Space Telescope completed its two-week-long deployment phase on Saturday, unfolding the final mirror panel as it readies to study every phase of cosmic history.
“The final wing is now deployed,” Nasa said on Twitter, adding the team was working “to latch the wing into place, a multi-hour process.”
Because the telescope was too large to fit into a rocket’s nose cone in its operational configuration, it was transported folded up. Unfurling has been a complex and challenging task – the most daunting such project has ever attempted, according to Nasa.
The most powerful space telescope ever built and the successor to Hubble, Webb blasted off in an Ariane 5 rocket from French Guiana on December 25, and is heading to its orbital point, a million miles (1.5 million km) from Earth.
Its infrared technology allows it to see the first stars and galaxies that formed 13.5 billion years ago, giving astronomers new insight into the earliest epoch of the Universe.
