A team of astronomers announces the discovery of a rocky exoplanet in our cosmic quarter, just 66 light years from Earth. More than 24 years after 51 Pegasi B, the first extrasolar world discovered and confirmed in 1995, our cosmic address book now has more than 4,100 exoplanets. However, the vast majority are gas or […]

The rapid increase in CO2 levels in the air threatens to severely degrade the cognitive abilities of students in the classroom. Results recently presented at the American Geophysical Union Meeting and which extend those obtained by previous work. In particular, they invite to take a more serious interest in this direct effect of CO2 in […]

Everyone admitted, nations have failed to make serious climate commitments. Between disappointment and anger, observers believe that this is a totally missed opportunity, an important missed opportunity to display the ambition to respond to the climate crisis. A bitter-tasting COP25 COP25, whose slogan was “Time for Action”, took place from December 2 to 13 in […]

A report from IUCN suggests that the oceans have lost a lot of oxygen since the 1960s. In addition, there are now fifteen times more “dead zones” than sixty years ago. Terrestrial species need oxygen to live, but let’s not forget that marine species also. You and I do not run out of oxygen. In […]

Scientists in Scotland have recently autopsied a sperm whale that has washed up on a beach. He had 100 kilos of garbage in his stomach. On November 30, members of the Scottish Marine Animal Strandings Scheme (SMASS) opened the belly of a sperm whale. The young mammal had come aground two days earlier on the […]

When a star like the Sun ages, it begins to swell until it becomes a red giant. When it reaches the end of its life, the star finally expels its outer layers of gas, leaving behind a dense nucleus. You then get a star corpse, called “white dwarf”. This is how our Sun will end […]

One study investigated the possible link between arctic melting in the Arctic and the spread of a virus. It is about a virus usually present in Atlantic mammals having contaminated other animals in the Pacific! An epidemic that questions In 2017, researchers had alerted about old viruses that could be “revitalized” by melting ice or […]

A team of researchers has recently developed small “artificial sunflowers” capable of tracking sunlight. What to maximize the yields of photovoltaic systems. Sunflowers, to survive, developed during their evolution a very interesting technique: heliotropism. The idea is to follow the sun’s light, source of heat, in order to warm their reproductive organs. In doing so, […]
