Here’s what the James Webb Space Telescope has seen in just a week of looking

A quintet of galaxies. A nursery of toddler stars. A climate report for an exoplanet. And a preview of our personal solar’s demise.

After years of delays, a 930,000-mile journey into house and months of hypothesis over what the James Webb Area Telelescope’s first photos would possibly reveal, NASA on Tuesday launched the primary full set of photos captured by its $10-billion observatory.

They present stars of their infancy and of their remaining gasps, together with sweeping views of the cosmos and the majestic objects in it.

“Each dot of sunshine we see right here is a person star, not in contrast to our solar. And plenty of of those probably even have planets,” NASA astrophysicist Amber Straughn mentioned whereas introducing a picture of the Carina Nebula, a multihued panorama of gasoline and nascent stars.

“It simply jogs my memory that our solar and our planets and, in the end, us had been fashioned out of the identical sort of stuff that we see right here,” she mentioned. “We people actually are linked to the universe. We’re made from the identical stuff on this lovely panorama.”

Because the universe expands, the earliest galaxies transfer away from us so rapidly that the seen gentle emanating from them is stretched into infrared wavelengths, which neither people nor the Hubble Area Telescope can see.

However Webb can. Which means it’s capable of see the very first stars that glowed. The telescope’s two infrared cameras — the Close to Infrared Digital camera (NIRCam) and the Mid-Infrared Instrument (MIRI), every tuned to completely different components of the sunshine spectrum — also can peer previous the mud and gasoline that generally obscure Hubble’s view.

“The pictures are completely spectacular,” mentioned Andrea Ghez, a UCLA astrophysicist who received the 2020 Nobel Prize in physics for her function in discovering the supermassive black gap on the the Milky Means’s core.

Later this yr, Ghez and her colleagues will use Webb to review star formation on the middle of our galaxy. Hers is certainly one of 286 analysis groups NASA has accredited to gather observations from Webb in its first yr.

“I can’t wait to see what these photos will reveal concerning the broader surroundings across the black gap,” she mentioned.

Michael Ressler, a scientist at NASA’s Jet Propulsion Laboratory in La Cañada Flintridge who helped design MIRI, mentioned the clearer photos of objects that had already been seen by the Hubble Area Telescope could also be gorgeous, however they’re not what he finds most fun — “it’s truly seeing issues that we’ve by no means seen earlier than.”

All the photos launched Tuesday level to one thing scientists didn’t know concerning the cosmos.

“It’s the sweetness but additionally the story,” NASA astrophysicist John Mather, Webb’s senior venture scientist, mentioned after the reveal. “It’s the story of the place did we come from.”

Right here’s a more in-depth take a look at what Webb noticed in its first weeks on the job.
