GREENBELT, Md – There has been a lot of interesting cosmic news lately. The Pentagon talks about the existence of “off-road vehicles.” NASA discovered the solar system, just like ours. The NEOWISE comet illuminates the night sky. If all this is not interesting enough, NASA officials are now giving the world a wonderful view of the sixth planet, Saturn.
Taken with the Hubble Space Telescope, Saturn’s icy rings are perfectly visible on July 4th. In the picture. Different color bars can be seen on the surface of the planet. Hubble’s photo also captures two of Saturn’s 82 months. Mim is seen on the right, and Enceladus is at the bottom of the stage, more than 800 million miles away.
Summer time on Saturn
A NASA team in Maryland says summer is currently in the northern hemisphere of the planet. Some scientists believe this is the cause of a small red mist covering Saturn. Increased exposure to sunlight due to extra heat can remove icy aerosols from the atmosphere.
It can also change the amount of photochemical mist. In the southern pillar, Saturn looks blue, probably because it’s there in the winter.
“It̵7;s amazing that we’re seeing seasonal changes in Saturn over the next few years,” chief researcher Amy Simon of Goddard Space Flight Center said in a press release.
What are those iconic rings made of?
The authors of the new post also make new observations about Saturn’s famous rings. They believe that the rings are mostly pieces of ice ranging in size from small grains to large boulders. NASA says it’s unclear how and when Saturn’s rings formed, but that doesn’t allow scientists to offer so many different opinions about it.
Some astronomers believe the rings formed when the planet was born more than four billion years ago. Others speculate that the rings are younger because they are so bright. Opponents of this theory do not see how bright rings could form in the last few hundred million years.
“Measuring small grains pouring into Saturn’s atmosphere on NASA’s Cassini spacecraft shows that the rings can only last another 300 million years, which is one of the arguments why the ring system is young,” says Michael Wong of the University of California, Berkeley. . .
Hubble has been in space since 1990. Edvid Hubble, a celebrity named after the telescope, became famous in the 1920s for discovering galaxies outside the Milky Way at his observatory in California.
