Space – like a beautiful marble on the edge of our solar system. space telescope James Webb Delivering unprecedented footage of Neptune and its rings that provide valuable information about its atmosphere, NASA announced Wednesday, September 21.
Astronomy scientists You haven’t had such a clear view of the farthest planet in the solar system since the short and unique passage of a probe, Voyager 2, near this icy giant in 1989.
The telescope’s infrared vision provides a new way to analyze its atmosphere, said Mark McGreen, Science and Exploration Adviser at the European Space Agency (ESA).

The telescope removes all glare from the sun’s reflection off Neptune’s surface and light pollution from its surroundings, so “to begin to guess the composition of the atmosphere” Of the planet, this astronomer who has worked for more than 20 years on the James Webb project told AFP.
Neptune had a bluish appearance in images taken in the visible wavelength range. Hubble telescopeBecause of the presence of methane in its atmosphere.

Using the James Webb NIRCam instrument, operating in the near infrared, the planet takes on a whitish-gray color. The image also appears “strange light” At one of the poles of Neptune PeopleIn a press release.
The telescope also took pictures of seven of the planet’s 14 known moons. In particular, Triton, whose brilliance resembles a small star. Larger than the dwarf planet Pluto, it also appears brighter than Neptune due to sunlight reflecting off its icy surface.

Astronomers looking for planets outside our solar system have found that those like Neptune or Uranus are the most common.
“Being able to observe these closely will make it easier to observe other (ice giants) orbiting other stars.” Of Our Sun, Mark McGreen explained.
In service since last July, James Webb is the most powerful space telescope ever deployed. It will allow some kind of astronomy “Which was unimaginable even five years ago”Mark McCogren said.
