On May 27, 2021, an American telescope discovered the second highest energy cosmic rays in the history of their discovery. The energy intensity was so enormous that it challenges our ability to understand particle physics. A recent publication in Science announces the discovery of a cosmic ray that fell to Earth on May 27, 2021, … [Read more…]
This paper in the journal Science (new window) traces CO2 levels from 66 million years B.C. BC to today’s global warming with unprecedented precision. “This shows us the extent to which what we are doing is really, really unusual in Earth’s history,” lead author Baerbel Hoenisch, a researcher at Columbia University in New York, told … [Read more…]
Current levels of carbon dioxide in the atmosphere have not been reached on Earth for 14 million years, according to a major study that highlights the inhospitable climate humanity is heading towards. This paper in the journal Science (New Window) tracks CO2 levels from 66 million years B.C. BC to today’s global warming with unprecedented … [Read more…]

Since this summer, astronomers from all over the world have enjoyed observing the evolution of comet 12P/Pons-Brooks as it travels toward our sun. For the fourth time, starting in July, the comet’s luminosity suddenly began to increase, shining at magnitude 9 in the constellation Hercules. According to astronomers, this sudden increase in brightness is a … [Read more…]
Several asteroids threaten Earth! Marc Hay November 19, 2023 1:00 p.m. 7 min Asteroids lurk in the quiet darkness of space, potential threats hovering over our planet. Their irregular flight paths sometimes bring them close to Earth, We raise concerns and questions about our vulnerability to these celestial behemoths. But what threat do these asteroids … [Read more…]
On Earth, geological activity and the resulting formation of continents are thought to have played a crucial role in the origin and development of life. According to this principle, if an exoplanet has continents, its habitability potential increases. A recent study shows that certain exoplanets in our Milky Way may have formed continents more than … [Read more…]
The universe is full of secrets. New research published in the September issue of the American Astronomical Society’s Research Notes journal suggests that a number of exoplanets at the edges of our galaxy may have formed continents over time. In this way, they would have advanced life five billion years earlier than Earth, reports Live … [Read more…]
According to a study published November 1, 2023 in the journal Nature, remnants of a planet could be found beneath Earth’s surface, a remnant of an ancient collision with another star called Theia. According to the authors of this study published in the journal Nature in early November, a planet billions of years ago would … [Read more…]
Since November, the Center for Research on Heteroepitaxy and its Applications has hosted 100 mg samples collected by NASA on the asteroid Bennu. Research on these fragments should make it possible to learn more about the formation of the solar system. A piece of an asteroid in Valbonne in the Alpes-Maritimes. The Center for Research … [Read more…]
