Saturn rings are disappearing this way. Soon we will have Saturn in its ring free state.

The planet Saturn has an extensive set of planetary rings in the Solar System. These iconic rings make it easily recognizable. These rings actually consist of numerous small dust particles that are ranging in size from the micro meter (μm) to a few meters (m) in size and orbit around the Saturn.

Recently, researchers have found that the rings of Saturn are now getting smaller than the previously thought and consequently, this feature of the planet won’t last much longer. However, these rings are less than 100 million old and still are a “new feature” of the planet that would not be sticking around the planet longer.

The ring components are made entirely of icy water material with a trace amount of rocky material. The mechanism of their formation is still unknown. The theoretical models indicate that the rings were likely to have formed early in the Solar System’s history, but new research data from Cassini suggests that they were formed on the order of 100 million years.

-Why Does Saturn have rings around it?

Galileo was the first person to observe the rings around Saturn through his telescope in 1610. But for four centuries, astronomers have been contemplating them, but all their efforts ended up in vain to explain why these rings exist and orbit about the Saturn.

But the answer to this question is given by Robin Canup during his research last month. He has published a new theory of the formation of rings in the science journal. He proposed that “the rings are icy remnants of a bygone moon. When Saturn came into existence along with other satellites and planet in the solar system, one of the large moons of Saturn got so close in order to maintain a stable orbit.

The moon then started to moved spiral about Saturn inward as a conseq-uence, Saturn’s gravity ripped away from its icy outer layers and flung them into orbit to create the rings we see today. After 10,000 years, the moon’s rocky leftover crashed into Saturn and crumble.

As we know that the Saturn consists of a ring system that orbit around it and the rings have countless separate particles with sizes ranging from pea-sized to giant boulders. The rings are mainly composed of frozen water and they are actively dumping a large amount of ice onto the planet constantly. This rain is responsible for the rings to be disappeared within 3 million years and this rain will soon turn the Saturn to the ring less state.

 A new research indicates that Saturn’s iconic rings are now getting smaller as previously observed and gradually disappearing at an extremely faster rate. The researchers from NASA found that the rings are draining away to-wards the planet as a dusty rain of ice particles. Since Saturn’s ring system mostly consists of water ice that ranges in size from microscopic dust to large boulders.

The ultraviolet light from the Sun and plasma clouds from tiny meteoroids strike charge the icy dust, which then becomes bound to Saturn’s magnetic field and pulled into the planet by gravity. This material rains into the pla-net and begins to disintegrate, allowing it to reacts chemically with the elec-trically charged part of Saturn’s upper atmosphere-the ionosphere. The ions glow in infrared light as a part of this process if the rain is light, but the emissions dim if the rain is heavy.

The Instruments attached to the Keck Telescope in Hawaii observed this rate of disappearance in the ring rain study and based on these observ-ations the scientists concluded that Saturn’s rings formed less than 100 million years ago. This means Saturn was not born this way, as the planet is known to be over 4 billion years old. And when the ring rain data is comb-ined with observations made by the Voyager 1 and 2 missions, scientists from NASA’s Goddard space station are able to estimate that the rings will be gone in 300 million years. So, if this rain doesn’t go away, Saturn will be ring-less another day. 



  1. First of all I want to say excellent blog! I had a quick question in which I’d like
    to ask if you do not mind. I was curious to find out how
    you center yourself and clear your mind before writing.
    I’ve had a hard time clearing my thoughts in getting my thoughts out.
    I truly do enjoy writing however it just seems like the first 10
    to 15 minutes are generally wasted just trying to figure out how to begin.
    Any ideas or hints? Kudos!

  2. I’m really inspired with your writing skills and also with the layout for your blog.
    Is this a paid subject matter or did you modify it your self?
    Anyway keep up the excellent quality writing, it’s uncommon to see a
    great weblog like this one nowadays..

  3. My brother recommended I might like this website.
    He was entirely right. This publish actually made my day. You cann’t
    imagine simply how a lot time I had spent for this info!
    Thank you!

  4. I don’t know if it’s just me or if perhaps everyone else experiencing problems with your site.
    It seems like some of the written text within your posts are running off the screen. Can someone else please provide feedback and let me know if this is happening to them as well?

    This might be a problem with my internet browser because I’ve had this happen previously.
    Many thanks

  5. I’m extremely inspired together with your writing talents as smartly as with the
    structure in your weblog. Is this a paid subject matter or
    did you customize it yourself? Anyway keep up the excellent quality writing, it’s uncommon to look a nice weblog like this one today..

  6. Wow, this piece of writing is good, my younger sister is analyzing such things, therefore I am going to inform her.

  7. Today, while I was at work, my cousin stole my iphone and tested to see if it can survive a 40 foot
    drop, just so she can be a youtube sensation. My iPad is now broken and she has 83 views.
    I know this is completely off topic but I had to share it with someone!

  8. Hello.This article was really remarkable, especially because I was browsing for thoughts on this topic last couple of days.
