A powerful solar storm hit Earth 9,000 years ago when the Sun was quiet
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…
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…
What are these dark “finger-like” structures seen in solar flares?
Twenty years that astronomers wonder what really hides behind the dark structures that seem to fall towards the Sun during an eruption. The hypothesis of a consequence of the magnetic…

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…
The Sun unleashed a powerful storm on the Earth 9,000 years ago when it was at its calmest

We are passing through a huge gas bubble on the surface of which stars are forming
Our Solar System is navigating through a particularly empty region of space. Surrounded by a local bubble, as astronomers call it. And today, they tell us how this bubble was…
Vitamin D: should it be taken in winter?
Vitamin D is made by the skin when exposed to sunlight. In winter, in the latitudes of mainland France, we risk suffering from a vitamin D deficiency. So, should we…
The Sun and the Moon would (a little) influence living beings
The Moon and the Sun move in space following a well-crafted choreography. And varying the gravitational forces exerted on the Earth. Are these gravimetric tides strong enough to influence behavior…
