James Webb Space Telescope
New space telescope shows Jupiter's auroras, tiny moons
The world’s newest and biggest space telescope is showing Jupiter as never before, auroras and all.
Scientists released the shots Monday of the solar system's biggest planet.
The James Webb Space Telescope took the photos in July, capturing unprecedented views of Jupiter’s northern and southern lights, and swirling polar haze. Jupiter's Great Red Spot, a storm big enough to swallow Earth, stands out brightly alongside countless smaller storms.
One wide-field picture is particularly dramatic, showing the faint rings around the planet, as well as two tiny moons against a glittering background of galaxies.

“We’ve never seen Jupiter like this. It’s all quite incredible,” said planetary astronomer Imke de Pater, of the University of California, Berkeley, who helped lead the observations.
“We hadn’t really expected it to be this good, to be honest," she added in a statement.
The infrared images were artificially colored in blue, white, green, yellow and orange, according to the U.S.-French research team, to make the features stand out.
NASA and the European Space Agency's $10 billion successor to the Hubble Space Telescope rocketed away at the end of last year and has been observing the cosmos in the infrared since summer. Scientists hope to behold the dawn of the universe with Webb, peering all the way back to when the first stars and galaxies were forming 13.7 billion years ago.

New space telescope reaches final stop million miles out
The world’s biggest, most powerful space telescope arrived at its observation post 1 million miles from Earth on Monday, a month after it lifted off on a quest to behold the dawn of the universe.
On command, the James Webb Space Telescope fired its rocket thrusters for nearly five minutes to go into orbit around the sun at its designated location, and NASA confirmed the operation went as planned.
The mirrors on the $10 billion observatory still must be meticulously aligned, the infrared detectors sufficiently chilled and the scientific instruments calibrated before observations can begin in June.

But flight controllers in Baltimore were euphoric after chalking up another success.
“We’re one step closer to uncovering the mysteries of the universe. And I can’t wait to see Webb’s first new views of the universe this summer!” NASA Administrator Bill Nelson said in a statement.
The telescope will enable astronomers to peer back further in time than ever before, all the way back to when the first stars and galaxies were forming 13.7 billion years ago. That’s a mere 100 million years from the Big Bang, when the universe was created.
Besides making stellar observations, Webb will scan the atmospheres of alien worlds for possible signs of life.
