James Webb’s sensors detected that 3I/ATLAS’s coma is composed primarily of carbon dioxide, an anomalous composition in the solar system. The James Webb Space Telescope (JWST), one of the most powerful observatories currently operating, took an image of 3I/ATLAS, the newly discovered interstellar comet transiting the solar system, for the first time. Infrared data made […]

For several weeks, an unexplained phenomenon has been taking place without interruption in China. Indeed, in the region of Inner Mongolia, dozens of sheep walk in a circle. According to some, it could be that the animals are affected by a disease affecting the nervous system, but this hypothesis does not seem to be verified. […]

The most powerful rocket built by NASA since the Apollo program is biding its time. Developed since 2011, this apricot-colored launcher will be responsible for sending crews to the Moon during the decade. If the SLS is not the future (too expensive and not reusable), we will have to rely on it for a few […]

NASA has just awarded several contracts aimed at demonstrating the potential of nuclear fission systems to power lunar infrastructures. The agency and the US Department of Energy have selected three design proposals that could be deployed on the Moon by the end of the decade to support the Artemis lunar exploration program. NASA and its […]

Future Starlink satellites will be larger and heavier than previous versions. To launch them, SpaceX will rely on the Starship, a fully reusable vehicle that will function as a gigantic PEZ dispenser. Once operational, SpaceX’s Starship will be the largest and most powerful space transportation system ever built. The company is developing its vehicle primarily […]

A new therizinosaurus dinosaur from the Osoushinai Marine Formation in Japan provides insight into the function and evolution of these animals’ claws. It is also the youngest therizinosaurus fossil from Japan and the first in Asia to have been found in marine sediments. A new dinosaur in Japan Therizinosaurs were a large group of theropod […]

Sakura trees are beautiful when they bloom, arousing fascination in many people. A recent study, however, suggests that this same flowering is increasingly earlier and would coincide with the increase in temperatures in Japan. However, this can have consequences on the surrounding fauna. Ever earlier flowering The term “sakura” refers to the ornamental cherry trees […]

A diffractive solar sail development project has moved into the third and final phase of NASA’s Advanced Concepts Program. The team behind the project now has two years to further develop this unconventional means of space propulsion. The concept of the solar sail has been known for a long time. Like a sailboat using the […]
