The Webb Telescope Just Peeked Into the Heart of a Fascinating Galaxy

The James Webb Space Telescope is so powerful that it can clearly see stars in the Milky Way 17 million light-years away.

Astronomers point to the most advanced space observatory ever built on the galaxy NGC 5068, peering deep into its stellar core. The bigger goal is to better understand how stars, like our energizing sun, is formed and evolves in galaxies. Importantly, the web sees a type of light that is invisible to the naked eye, called infrared light. These long infrared light waves penetrate thick clouds of cosmic dust and gas, giving us unprecedented views into galactic hearts.

“With its ability to peer through the gas and dust that surrounds newborn stars, Webb is the perfect telescope to explore the processes governing star formation,” the European Space Agency said in collaboration on the telescope. NASA And the Canadian Space Agency wrote. The Solar System The cosmic dust-wrapped birth cannot be seen with visible light telescopes like Hubble, the space agency said.

In the image below, Webb peered through “huge clouds of dust.” Here’s what you’re seeing:

• The bright white bar is the core of the Milky Way. Similar to the Milky Way, NGC 5068 is a barred spiral galaxy, meaning that it has a long bar-shaped structure at its center, which is densely packed with stars.
• All the bright points in the core and populating the image are stars. Many thousands are visible. And although we can’t see them, many of those stars almost certainly harbor wild, alien planets.
• To the right is the curved, spiral arm of the Milky Way. (In our galaxy, the Earth resides reach of a spiral arm,
• The ESA explains that the general skeleton-like structure in the Milky Way is made up of clumps and filaments of dust.

The Webb Telescope is designed to peer into the deepest universe and reveal unprecedented insights about the early universe. But it’s also tracking our interesting planets GALAXYAnd even the planets of our solar system.

Here’s how the web is achieving unique things, and possibly decades:

• Giant Mirror: Webb’s mirror, which captures the light, is more than 21 feet wide. It is two and a half times larger than the mirror of the Hubble Space Telescope. Taking in more light allows Webb to see more distant, ancient objects. As mentioned above, the telescope is looking at stars and galaxies that formed 13 billion years ago, just a few hundred million years after the Big Bang.

  “We’re going to see the very first stars and galaxies forming,” Gene Creighton, an astronomer and director of the Manfred Olson Planetarium at the University of Wisconsin-Milwaukee, told Mashable in 2021.

• Infrared view: Unlike Hubble, which largely observes light visible to us, Webb is primarily an infrared telescope, meaning it observes light in the infrared spectrum. This allows us to see more of the universe. Infrared is long wavelength Compared to visible light, therefore, light waves slip through cosmic clouds more efficiently; Light often does not collide with these densely packed particles and is not scattered. Ultimately, Webb’s infrared vision can penetrate places Hubble cannot.

  “It lifts the veil,” Creighton said.

• Peeking into distant exoplanets: webb telescope carries a special instrument called a spectrometer Which will revolutionize our understanding of these distant worlds. The instruments can understand which molecules (such as water, carbon dioxide and methane) are present in the atmospheres of distant exoplanets – whether gas giants or small rocky worlds. Webb will look for exoplanets in the Milky Way galaxy. Who knows what we’ll find.

  “We can learn things we never thought about,” Mercedes López-Morales, an exoplanet researcher and astrophysicist Center for Astrophysics-Harvard & Smithsoniantold Mashable in 2021.

  Already, astronomers have successfully detected intriguing chemical reactions on a planet 700 light-years away, and the observatory has begun looking at one of the most anticipated places in the universe: TRAPPIST, the solar system’s rocky, Earth-sized planet. Planet.
