In a Landmark Study, Scientists Discover Just How Much Earth’s Temperature Has Changed Over Nearly 500 Million Years
Researchers show the average surface temperature on our planet has shifted between 51.8 to 96.8 degrees Fahrenheit
Earth Had Rings Like Saturn Millions of Years Ago, Study Suggests
A weird number of craters are located close to the equator, and the odds that this is random are incredibly low, researchers say.
Earth may have once had a Saturn-like ring system, new evidence suggests
To reach that surprisingly conclusion, scientists studied the positions of 21 asteroid impact craters during the Ordovician period – the second of six periods in the
Earth once wore a Saturn-like ring, study of ancient craters suggests
Earth may have had a giant ring of space rocks surrounding it, similar to those around Saturn, which could have led to chaotic meteorite strikes on our planet's surface, new research suggests. The hypothesized ring may have formed roughly 466 million years ago and was the remains of a gigantic asteroid tugged apart by Earth's tidal forces after passing our planet's Roche limit.
Earth May Have Had Rings Like Saturn 466 Million Years Ago
"Over millions of years, material from this ring gradually fell to Earth, creating the spike in meteorite impacts," said researcher Andy Tomkins.
Earth may once have had a ring like Saturn
A ring of asteroid debris could have orbited Earth for tens of millions of years, and perhaps even have altered the planet's climate
Earth may once have had Saturn-like ring, scientists say
Earth may briefly have had a ring system similar to Saturn’s over 450 million years ago during a period of unusually intense meteorite bombardment, a new study proposes. Scientists assessed 21 asteroid craters from the “Ordovician impact spike” period 466 million years ago and noticed that these were strangely located in a narrow band of land close to the equator,
Scientists unveil theory: Earth once had Saturn-like rings
Scientists have concluded that the Earth may have had a ring system similar to Saturn's based on the analysis of the location of craters on our planet. Scientists claim that over 450 million years ago,
The Earth had a Saturn-like ring of its own once, a shocking new study has suggested
Scientists suggest Earth had a colossal ring of space debris 466 million years ago, leading to meteor showers and a significant cooling event.
