A second Trojan asteroid from Earth has been discovered
Each planet in the Solar System orbiting the Sun has Lagrange points, the most famous of which in the case of Earth is L2, where the James-Webb telescope is in…
The amount of oxygen on Earth would have long stagnated at very low levels
The amount of oxygen in the atmosphere would have long stagnated at particularly low levels, impacting the development of the biosphere. New results that could lead to a revision of…
There are 73,000 species of trees on Earth, with more than 9,000 yet to be discovered.
More than 100 researchers from around the world conducted a study to estimate the number of tree species on Earth. They have developed the largest database and estimate the existence…
A powerful solar storm hit Earth 9,000 years ago
The biggest solar flares appear during the most intense periods of activity of our Star. It’s known. But researchers now show that around 9,200 years ago, a major storm erupted…
Even calm, the Sun can unleash powerful storms on the Earth, like 9,000 years ago
The biggest solar flares appear during the most intense periods of activity of our Star. It’s known. But researchers now show that around 9,200 years ago, a major storm erupted…
Why do we always see the same side of the Moon?
If we always see the same side of the Moon, it is because our natural satellite takes the same time to go around itself as it does around the Earth.…
Extraterrestrial life: life as we know it on Earth could also exist on Mars
Some environments on Earth are unmistakably similar to those that may have existed on Mars in the past. And in these environments, researchers find living organisms endowed with formidable adaptive…
Bacteria in hydrothermal vents are great energy powerhouses
Some hypotheses suggest that life appeared at the bottom of the oceans at hydrothermal vents. The bacteria currently observed there are based on methanogenesis, a process that releases energy if…
The Sun unleashed a powerful storm on the Earth 9,000 years ago when it was at its calmest
The biggest solar flares appear during the most intense periods of activity of our Star. It’s known. But researchers now show that about 9,200 years ago, a major storm erupted…
How fast do the continents move?
We are not aware of it, but the tectonic plates move slowly under our feet, at the speed of a few centimeters per year, driven by major tectonic and convective…
