A recent study published in Nature Astronomy suggests that the methane concentrations measured by Cassini in the plumes of Enceladus could have a biological origin. This methane production could also be the result of non-biological geochemical processes unknown on Earth. Where does Enceladus methan

In collaboration with private companies, Japan is preparing the development of intercontinental spacecraft connecting the main cities of the world in two hours. In any case, this is what a recent report indicates. On May 12, the Japanese Ministry of Education, Culture, Sports, Science and Technolog

Last February, NASA set its sights on the Northtop Grumman company to develop the engines that will power the rocket responsible for placing the Martian samples set aside by Perseverance into orbit. , where they can be collected to be brought back to Earth. The course of the mission You know it:NAS

Less than a year ago, NASA announced that the Sun had begun a new cycle of activity. For eleven years, it will be about major solar flares. However, these could harm our technological world, because their magnitude is still quite difficult to imagine. A new cycle of solar activity The media often t

Endowed with artificial intelligence, the Perlmutter supercomputer should help in the study of dark energy and the acceleration of the expansion of the Universe . His goal ? Help make the largest 3D map of the visible Universe. A very important mission The Perlmutter is one of the most powerful sup

Little, viable mice are born from freeze-dried sperm that spent years around the planet aboard the ISS. This work, the results of which are published in Science Advances , allow a better understanding of the effects of space radiation on living organisms and their heritage. Those who follow space n

A mini wooden satellite will soon be released into space for the first time. Integrated sensors will be responsible for evaluating the potential of the material in the space environment. But concretely, why turn to wood? The worlds first wooden satellite will be placed in orbit before the end of th

New images of the stars surface taken using ESOs Very Large Telescope shed light on recent and mysterious dips in brightness of the star Betelgeuse. The culprit is a gigantic cloud of dust. Betelgeuse, a supergiant found in the Constellation of Orion, is an end-of-life star likely to explode within

On June 13, 2021, the Hubble Space Telescope stopped working due to a problem with its payload computer. This malfunction is probably related to prolonged exposure to radiation from space. Operations are underway to attempt to repair the observatory. Hubble, which celebrated its 30th year in orbit

Researchers have recently been able to measure the shape of the heliosphere, the protective bubble surrounding our solar system. This new study could help us better understand the environment of the Solar System and how it interacts with interstellar space. What is the heliosphere? The heliosphere

In just over a year, after traveling more than seven million miles, a small vessel the size of a dishwasher will pounce on a small asteroid, itself orbiting a larger one as part of the DART mission. If all goes as planned, the trajectory of the small moon will have deviated enough to be detectable f

Planets, stars, galaxies and other clusters of galaxies… All these objects evolve in rotation in the Universe. A recent study suggests that angular momentum is also at work at much larger scales. Its hard to imagine the structure of the Universe from our point of view, but if you took a long, long

NASA recently released a photo of a mannequin nicknamed Moonikin. This first (false) passenger will fly aboard the Artemis I mission to prepare for the return of humans to the Moon. If all goes as planned, NASA will kick off its Artemis program next November with the launch of Artemis 1, the first

If aliens ever visit us, its likely to be an artificial life form, says an astronomer from the Seti Institute. An organic life form such as ours could not sustain such a long stay in space. Seth Shostak is an astronomer at the Seti Institute, a non-profit organization focused for several years on t

A team of astronomers announces that they have isolated a gigantic row of galaxies spanning more than 3.3 billion light years. If the discovery is confirmed, it would be one of the largest structures ever identified in the Universe. The cosmological principle of homogeneity and isotropy tells us th

Turkey plans to send a rover to the Moon by 2030. This mission should rely on a domestically built rocket engine, the first of which launch should take place in 2023. A first Turkish astronaut should also integrate the International Space Station in a few years. In 2020, NASA shared its Artemis Acc

As the Covid-19 pandemic continues to impact many countries, so too does the shortage of electronic components. It thus involves various sectors and could also affect the space sector, including satellite manufacturers. Industry giants stronger than small ones For several months, a shortage of semi

The strange spiral drawn in the New Caledonian sky on June 18 is finally explained. According to American astronomer Jonathan McDowell, a specialist in space launches, this spectacular phenomenon was the work of the degassing of a Chinese rocket. A spiral in the sky The recent report on unidentifie

As part of a competition organized by NASA, the Masten company proposes the development of a rover capable of extracting ice from the lunar surface to turn it into water vapour. Very precious, this resource could be used by the astronauts of the Artemis program on the Moon. NASA and its partners pl

Dmitry Rogozin, director general of Roscosmos, recently expressed his intention to send cosmonauts to the new Chinese space station. If such a collaboration materializes, several technical challenges will have to be met. A few days ago, China again made an impression by sending its first crew to it
