Нептун и Уран: Ледене гиганте показују нове боје планета

New research has unveiled surprising new colors for the icy giants of our solar system, Neptune and Uranus. While Neptune has long been known as the “blue planet” and Uranus as the “green planet,” recent studies show that these two planets may have more similar hues than previously thought. Professor Patrick Irwin, an American astrophysicist, presented the findings of his research, revealing that both planets have a shade of bluish-green.

This new understanding of the colors of Neptune and Uranus comes from the application of a new model to original data and the reconstruction of the most accurate representation of their colors. Professor Irwin emphasizes the significance of this research, which combines quantitative models with imaging data to provide an informative and unique representation of the colors of Neptune and Uranus.

The study also addresses the question of why Uranus’ color changes during its orbit around the Sun. By studying the light emitted from the Observatory Lovell in Arizona, researchers discovered that Uranus slightly greens during solstices (summer and winter) while appearing blue during equinoxes. This can be explained by the unusual rotation of Uranus, which tilts almost on its side during its orbit, resulting in a greater concentration of scattered methane particles in those regions.

This research helps us better understand our icy giants and answers questions that have been a mystery for decades. We now see Neptune and Uranus in a new light, as bluish-green planets in our solar system.

Frequently Asked Questions

Why did we think Neptune was blue and Uranus was green?

Old photographs of Neptune were retouched and shifted towards blue, while images of Uranus were closer to the planet’s actual color. This influenced our perception of both planets’ colors.

Why does Uranus’ color change during its orbit?

Uranus’ rotation, which tilts on a slant during its orbit, results in a greater concentration of dispersed methane ice, which affects the planet’s color.

How was this experiment conducted?

Professor Irwin applied a new model to the original data and reconstructed the colors of Neptune and Uranus, a process that required precision and accuracy.
