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

The planets in our solar system are not as fixed as Earth, and other planets also experience seasonal changes with changes in the atmosphere that occur throughout the year, according to a digitaltrend technical report.

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

And this year’s “Grand Tour” photos of the outer solar system have been published showing gas giants and ice giants that are very different from the rocky inner planets of Mercury, Venus, Earth and Mars. Twice the distance between the Earth and the Sun – it is also very cold.

It’s made up of different materials, too, and consists of what the European Space Agency describes as a “cold, gaseous soup of hydrogen, helium, ammonia, methane and other trace gases around a packed, compressed, superheated core.”

This year’s images show the ever-changing atmosphere of Jupiter, as new storms appear regularly and form shapes called barges. Another feature that appears in the image is the “son red dot”, a smaller spot that appeared under Jupiter’s famous Great Red Spot.

“Every time we get new data, the image quality and the detail in the cloud features always amazes me,” said Amy Simon of Goddard Space Flight Center in Greenbelt, Maryland. directly .

Saturn approaches autumn in the northern hemisphere, when there are color changes in its bands, and in the southern hemisphere, you can see the remains of winter in blue around the south pole of the planet.

And this is something we can do better with Hubble, and Michael Wong of the University of California, Berkeley, said: “Thanks to Hubble’s high resolution, we can narrow things down to the scale that is really changing,” said Michael Wong of the University of California, Berkeley, “If you look at this through a ground-based telescope, there is some blur in the Our atmosphere, you lose some of these color differences, and nothing from Earth will get visible-light images with the same resolution as the Hubble images.

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