Two galaxies are merging successful nan heavy cosmos. And nan James Webb Space Telescope conscionable captured a vivid position of nan scene.

The interacting galaxies, called Arp 107, collided hundreds of millions of years ago, and a span of stars has formed betwixt them arsenic they acquisition nan long, gradual process of merging into one. Our Milky Way, too, has merged before, and may, successful nan distant future, meld pinch an moreover larger galaxy.

Here's what you're seeing successful Webb's caller image, which shows an arena transpiring 450 cardinal light-years way:

- Older stars and nan bridge: The achromatic areas are older stars, which you tin spot plentifulness of successful some nan galaxies. These stars besides dress up nan "tenuous span of state and stars that runs betwixt [the galaxies]," nan European Space Agency (ESA) explained.

- Vibrant prima formation: When galaxies collide pinch 1 another, their gasses meet and condense. The resulting weighty clouds of state tin collapse, driving nan statement of caller stars. In this image, Webb's Mid-Infrared Instrument reveals these expansive star-forming regions successful orangish and red.

- Deep abstraction galaxies: Nearly each those objects successful nan inheritance are distant galaxies — galore spirals for illustration ours — each teeming pinch their ain stars, and apt planets.

Space is so vast, but galaxies collide because they harbor unimaginable amounts of gravity, and are attracted to each other. "It's very apt that a postulation will brushwood a postulation comparable aliases smaller complete nan people of its lifetime," Diego Muñoz, an astrophysicist astatine Northern Arizona University, recently told Mashable.

But conscionable because these behemoth objects collide doesn't mean nan planets they incorporate are doomed. There are immense distances betwixt nan stars, and stars are comparatively tiny. "In fact, if you were to shrink nan sun to nan size of a soil grain, nan region to nan nearest prima would beryllium measured successful miles. That makes adjacent encounters pinch different stars highly unlikely, moreover during a postulation merger," Sally Dodson-Robinson, a planetary intelligence astatine nan University of Delaware, told Mashable.

The Webb telescope's powerful abilities

The Webb scope — a technological collaboration betwixt NASA, ESA, and nan Canadian Space Agency — is designed to adjacent into nan deepest cosmos and uncover caller insights astir nan early universe. But it's besides examining intriguing planets successful our galaxy, on pinch nan planets and moons successful our star system.

Here's really Webb is achieving unparalleled feats, and likely will for decades to come:

- Giant mirror: Webb's mirror, which captures light, is complete 21 feet across. That's complete two-and-a-half times larger than nan Hubble Space Telescope's mirror. Capturing much ray allows Webb to spot much distant, ancient objects. The scope is peering astatine stars and galaxies that formed complete 13 cardinal years ago, conscionable a fewer 100 cardinal years aft nan Big Bang. "We're going to spot nan very first stars and galaxies that ever formed," Jean Creighton, an astronomer and nan head of nan Manfred Olson Planetarium astatine nan University of Wisconsin–Milwaukee, told Mashable successful 2021.

- Infrared view: Unlike Hubble, which mostly views ray that's visible to us, Webb is chiefly an infrared telescope, meaning it views ray successful nan infrared spectrum. This allows america to spot acold much of nan universe. Infrared has longer wavelengths than visible light, truthful nan ray waves much efficiently gaffe done cosmic clouds; nan ray doesn't arsenic often collide pinch and get scattered by these densely packed particles. Ultimately, Webb's infrared eyesight tin penetrate places Hubble can't.

"It lifts nan veil," said Creighton.

- Peering into distant exoplanets: The Webb scope carries specialized instrumentality called spectrographs that will revolutionize our knowing of these far-off worlds. The instruments tin decipher what molecules (such arsenic water, c dioxide, and methane) beryllium successful nan atmospheres of distant exoplanets, beryllium they state giants aliases smaller rocky worlds. Webb looks astatine exoplanets successful nan Milky Way galaxy. Who knows what we'll find?

"We mightiness study things we ne'er thought about," Mercedes López-Morales, an exoplanet interrogator and astrophysicist astatine nan Center for Astrophysics-Harvard & Smithsonian, told Mashable successful 2021.

Already, astronomers person successfully recovered intriguing chemic reactions connected a planet 700 light-years away, and person started looking astatine 1 of nan astir anticipated places successful nan cosmos: nan rocky, Earth-sized planets of nan TRAPPIST star system.
