The latest deep space observer, the James Webb Space Telescope, will give us a deeper insight into the infrared universe than the Hubble satellite.
A new video from the European Space Agency (ESA) shows how Webb is opening up new perspectives to astronomical objects around the universe, from galaxies formed billions of years ago to the clouds of gas and dust surrounding the newborn stars.
Infrared light is a heat -carrying piece of the electromagnetic spectrum with wavelengths longer than visible light. The Hubble Space Telescope is powered by visible light but can detect some ultraviolet (shorter wavelengths than is detected) and some infrared. Webb was developed as an infrared technology that could carry long infrared waves. That is, for example, it has a deeper understanding of the universe than Hubble.
As the universe expands, galaxes in the distance are much faster than those in the near future. The light emitted by these galaxes is changed to have longer, redder, longer wavelengths, due to the Doppler effect (the same effect that converts the sound of a moving car), as seen redshift returns to astronomy.

With better ideas around the world, NASA announced a separate release last year about Webb’s infrared powers, which astronomers hope will gain more information about how with the growth of galaxies.
Because of the small amount of infrared light in the obstruction from the Earth, Webb allows astronomers to see what is going on in the Earth’s clouds in the near universe. “We can get into the ground and see the processes that lead to the formation of the star and the earth,” ESA said in a statement.
This means, for example, that Hubble’s 2020 view of the Eagle Nebula “Pillars of Creation” differs from infrared from Webb’s infrared view. The Pillas are a popular site for star formation, where Webb provides more information.
“Stars around the universe are located in the centers of flat, dusty clouds, which cover our eyes with visible wavelengths,” ESA said in a statement.
Looking at things in the universe to provide additional answers will further help astronomers build their understanding of the evolution of the universe.
“We need to understand the universe in order to understand the universe,” said Martha Boyer, managing director of Webb near-infrared cameras (NIRCam), one of two cameras on Webb’s board. create infrared sensors. said in the NASA release.
Speaking about the galaxies closest to us, the Milky Way, Boyer said that the so-called ‘Local Group’ is a mini-laboratory where astronomers can observe the galaxies. in higher definition.
The Earthquake consists of three large galaxes, the Milky Way, all located within 5 million light -years of Earth, according to EarthSky. Andromeda is the largest of these galaxies, the Milky Way is the center, and the galaxy called Triangulum is the smallest of the three. The group also includes about 50 dwarf galaxies in most large galaxies.
According to Boyer, we can’t determine the exact details, so we’re not sure what’s going on.
