Scientists have long said Saturn’s rings are not permanent and may disappear in time. That “time” may have started as Saturn is losing its rings, scientists claim.
New research from NASA scientists found that Saturn’s iconic rings are disappearing, and it’s happening faster than expected. The scientists estimate that the rings will be gone in 300 million years, or sooner. The planet’s gravity slowly pulls the rings, which are the brightest and biggest rings in the solar system.
They're wide enough to fit six Earths in a row.
The scientists project that the rate of ring disappearance is fast enough to fill an Olympic-size pool in 30 minutes, according to a study published in the journal Icarus.
James O’Donoghue of NASA’s Goddard Space Flight Center, lead author of the study, said:
“From this alone, the entire ring system will be gone in 300 million years, but add to this the Cassini-spacecraft measured ring-material detected falling into Saturn’s equator, and the rings have less than 100 million years to live. This is relatively short, compared to Saturn’s age of over 4 billion years.”
In the past, scientists wondered if Saturn had the rings when it was formed, or they appeared later in life. But, the new study shows that these rings were formed after the birth of the planet, which means they’re unlikely to be older than 100 million years.
Saturn's rings were formed long after the birth of the planet.
“We are lucky to be around to see Saturn’s ring system, which appears to be in the middle of its lifetime. However, if rings are temporary, perhaps we just missed out on seeing giant ring systems of Jupiter, Uranus, and Neptune, which have only thin ringlets today.”
The rings are composed of many separate particles, ranging from pea-sized particles to giant ones.
These are made of chunks of water ice, which can be microscopic grains to huge boulders. However, there are also traces of rock materials in these rings. Though people today may not be able to witness the disappearance of Saturn’s rings, we’re lucky enough to know that the rings are still existing.
Scientists Destroy HIV-Positive Cells In Major Breakthrough
The new discovery could change the future for HIV-positive patients.
The cure for AIDS might finally be here. A group of scientists has successfully destroyed HIV-positive cells in a major breakthrough.
The researchers at Institut Pasteur in Paris have revealed that they might have a cure for AIDS. According to the scientists, they have successfully destroyed cells infected with the virus. Although the cells are typically treated with antiretroviral drugs, they claim to have found a way to eliminate infected cells.
Scientists may have found a way to combat the HIV virus in the body.
So how does it work? According to the medical journal Cell Metabolism, the scientists' discovery works in conjunction with antiretroviral drugs. Although the medication is able to block the infection, it is unable to remove the virus from the body. The breakthrough found a way to target the virus hiding in cells and completely destroy it....
NASA’s Official Mission Posters Are Awesome And Cringeworthy At The Same Time
Yes, NASA has official movie-style posters for their space missions!
As kids, most of us grew up dreaming of becoming astronauts. In our young eyes, we saw it as the coolest job in the world. Besides, astronauts get to explore outer space alll the time - just like in our favorite sci-fi movies.
Well as it turns out, there's at least one more similarity between astronauts and movies. In a BoredPanda feature, we learn that the National Aeronautics and Space Administration (NASA) actually has official posters for their space missions and many of them are direct references to pop culture.
As the article tells us:...
Ancient 99-Million-Year-Old Frogs Look Just Like Modern-Day Toads
Frogs will always be frogs, whether they were born today or in the Cretaceous Period.
The world is filled with exciting new discoveries from ancient times. Scientists have just uncovered evidence that frogs roamed the Earth during the Cretaceous Period about 100 million years ago. Interestingly, these ancient toads seem to look just like their modern-day descendants.
A new report confirms that scientists have found four frog fossils in northern Myanmar. The tiny bodies were encased in amber and offer a clear glimpse at what tropical rainforests looked like in the Cretaceous Period. In any case, the discovery is groundbreaking since frogs rarely become fossils.
One of the amber deposits reveals that the ancient frogs had died beside a few tiny insects.
David C. Blackburn, one of the authors of the new study, explains why the ancient frog fossils are special....
