Find out why the Hubble Space Telescope takes pictures of exoplanets each year

The planets in our solar system are not as stable as Earth, and other planets are experiencing seasonal changes with changes in the atmosphere throughout the year, according to the Digital Trend Technology Report.

That’s why every year the Hubble Space Telescope takes pictures of the outer planets of our solar system, such as Jupiter, Saturn, Uranus and Neptune, so astronomers can see how they change over time.

This year’s “Grand Tour” images of the outer solar system showing gas giants and ice giants very different from the rocky inner planets Mercury, Venus, Earth and Mars were released. These extrasolar planets are very large, and they are far from the Sun – the farthest Neptune orbits at 30 times the distance between the Earth and the Sun – which is also very cold.

It is made up of a variety of materials, and the European Space Agency describes it as “a cold, gaseous soup of hydrogen, helium, ammonia, methane and other trace gases that surrounds the center of a superheated, condensed, superheat.”

This year’s images show that Jupiter’s atmosphere is constantly changing, with new storms constantly appearing and forming what is known as barges.

“Every time we get new data, the quality of the film and the details in the cloud features always amaze me,” said Amy Simon of the Goddard Space Flight Center in Greenfield, Maryland.

Saturn is approaching autumn in the Northern Hemisphere, and when there are color changes in its bands, in the Southern Hemisphere, you can see the remnants of winter in blue around the planet’s south pole.

This is something that can be done better with Hubble, and said Michael Wong of the University of California, Berkeley: “Thanks to Hubble’s high clarity, we can really reduce things to a changing level.” University of California, Berkeley, “If you look at this with a ground – based telescope, you’ll miss some of our atmosphere, some of these color variations, and nothing from the Earth will receive visible-light images with the same resolution. Hubble images.

Finally, Uranus and Neptune also showed changes, the bright north pole of Neptune being caused by ultraviolet radiation, the dark northern hemisphere of Uranus and a dark point moving around the planet.
