In short, if Earth had rings, life would probably still exist, but not life as we know it.
The rings would probably reflect so much sunlight that the planet would never fully plunge into darkness, but remain in a gentle twilight even in the depth of night. During the day, the rings could potentially cause light levels on Earth to skyrocket [source: Atkinson].
Although Earth doesn't have a ring system today, it may have had one in the past. All gas giant planets (Jupiter, Saturn, Uranus and Neptune) in the Solar System have rings, while the terrestrial ones (Mercury, Venus, Earth and Mars) do not.
The rings would have to be made out of rock, because if they were ice, they would quickly melt. If you lived near the equator, you would see a thin band of light across the sky, but the further you moved up or down the earth, the larger the rings would appear. The ISS would run into some troubles with potentially.
Hence, it's possible that there was a stage of our planet's history that the researchers dubbed “Purple Earth”. That time would date somewhere between 2.4 to 3.5 billion years ago, prior to the Great Oxygenation Event, which was likely due to the rise chlorophyll-based photosynthesis.
Earth once had two moons, which merged in a slow-motion collision that took several hours to complete, researchers propose in Nature today. Both satellites would have formed from debris that was ejected when a Mars-size protoplanet smacked into Earth late in its formation period.
Though Kepler 16b is even closer to its two suns than we are to our one, it registers temperatures of around minus-100 degrees Fahrenheit. So, if we kept our same distance despite doubling up on smaller suns, Earth would be a bleak and icy place – and the chances of life would be extremely low.
During the summer in the Northern Hemisphere and the winter in the Southern Hemisphere, the rings would cast their shadows on the Southern Hemisphere, and vice versa. This could mean that winters in both hemispheres might be colder and more severe than they are on our Earth.
Cassini observed that the rings were losing many tons of mass per second, which means the rings don't have much time left, astronomically speaking. The researchers estimate that the rings will only be around another few hundred million years at most.
Introduction. The seventh planet from the Sun with the third largest diameter in our solar system, Uranus is very cold and windy. The ice giant is surrounded by 13 faint rings and 27 small moons as it rotates at a nearly 90-degree angle from the plane of its orbit.
Life would be: Built and proportioned differently. If gravity were twice as strong, bodies possessing the same construction and mass as our flora and fauna would weigh twice as much and would collapse. It'd be "timber!" for tall, thick trees such as redwoods.
No, the One Ring would be slightly diminished but it would still grant other powers. First of all, you don't just “destroy the other rings of power.” It's not that easy. The Ringwraiths are the human bearers of nine rings of power, and they are neither going to take them off or die easily.
("Air" on Saturn is mostly hydrogen.) The color there is blue. "Saturn's skies are blue, we think, for the same reason Earth's skies are blue," says West. Molecules in the atmosphere scatter sunlight.
It has been 34 years since the film was released, though in the timeline of the series, “200 moons” have passed, or 16.66666 years, according to my calculator.
Venus and Earth are sometimes called twins because they're pretty much about the same size. Venus is almost as big as Earth. They also formed in the same inner part of the solar system.
Before Earth and the Moon, there were proto-Earth and Theia (a roughly Mars-sized planet). The giant-impact model suggests that at some point in Earth's very early history, these two bodies collided.
The name Earth derives from the eighth century Anglo-Saxon word erda, which means ground or soil, and ultimately descends from Proto-Indo European *erþō. From this it has cognates throughout the Germanic languages, including with Jörð, the name of the giantess of Norse myth.
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.
Researchers discovered the ancient pink pigments in 1.1-billion-year-old rocks deep beneath the Sahara Desert in the Taoudeni Basin of Mauritania, West Africa, making them the oldest colors in the geological record.
Notable astrophysicist Neil deGrasse Tyson, some time back, had revealed how all living beings on our planet would die if the Earth were to stop rotating even for one second. The scientist had said that the incident could have similar implications as one not wearing a safety belt during a severe car accident.
The closest planet to us, Proxima Centauri b, is a super-Earth discovered in 2016. Its existence is known from detecting the slight wobbles of its star, which are caused by Proxima Centauri b's pulls and tugs. But none of our current telescopes are positioned to capture light from its atmosphere.
While modern Earth's surface is about 70 percent water-covered, the new research indicates that our planet was a true ocean world some 3 billion years ago. At this point, only scattered archipelagos breached our global ocean's briny surface. That is, if any land existed at all.
