Astronomers drawing on data from the Galactic Evolution Experiment (APOGEE), Apache Point Observatory, have isolated the presence of a fossil galaxy hidden in the depths of the Milky Way. In the universe, everything is in motion. It then sometimes happens that certain galaxies approach each other,

Could Mars be made habitable by restoring its atmosphere? Maybe one day, but not in this lifetime, says Elon Musk . In the meantime, if our species wants to settle on Mars, it will therefore have to deal with the particularly brutal environmental conditions of the red planet, and probably live under

NASAs Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, the presence of water on the moons sunlit surface. Great news for the future of human exploration of our satellite. This Friday, NASA teased us with an exciting discovery about the Moon from the Strato

The United States Space Agency has just announced two important discoveries about the Moon, this October 26, 2020. One of them concerns the presence of water as ice trapped in cold traps at the poles. And inevitably, there could be implications for the Artemis program. A few hours ago, NASA confirm

NASA is enlisting Houston-based Intuitive Machines to land an ice extractor on the Moons south pole in 2022. A new collaboration that will is part of the Artemis program of the American agency. Unless youve been living deep in a cave for several years, you know that NASA aims to rest astronauts on

Since leaving Florida on July 30, the Mars 2020 mission and its Perseverance rover are already halfway through their journey to the red planet. Landing is still scheduled for next February. On July 30, NASAs Mars 2020 mission was launched. Its goal is to deploy the Perseverance rover to the surface

NASA researchers announce that they have identified cyclopropenylidene in Titans atmosphere, and this is a first. This extremely rare molecule is so reactive that it can only exist on Earth in the laboratory. If youve never heard of cyclopropenylidene, or (C3H2), thats normal. It is indeed an extre

A team of astronomers announces that they have detected a wandering planet of Earth size, even Mars size. This is the first time that such a solitary world has been discovered. To date, we have discovered more than 4,000 exoplanets. There is everything:large, small, rocky, gaseous, very hot worlds

A few days ago, SpaceX invited some North American users to participate in public beta testing of its Starlink program. To participate, users must purchase all equipment on the ground and then pay a still very expensive monthly fee. On October 26, sixty new satellites joined the Starlink megaconste

Based on data from Kepler and Gaia telescopes, a team of astronomers tried to estimate the number of potentially habitable planets in the Milky Way. Details of this work are published in The Astronomical Journal. Proposed in 1961 by Dr. Frank Drake, the Drake Equation is a famous formula for estima

The list of objects posing a potential threat to Earth is quite short, but the asteroid Apophis is one of them. Recent follow-up analyzes indeed suggest that the object could still strike the Earth in 48 years. But that would be really bad luck. On April 13, 2029, we know that an asteroid 340 meter

A team of researchers announces that they have analyzed an almost unaltered meteorite that fell in Michigan two years ago. This work has made it possible to isolate thousands of organic compounds that may have participated in the development of life on Earth. A meteorite that fell to Earth Through

Before coming to rest on Comet Tchouri six years ago, the lander Philae bounced off the surface several times, sinking into a ice cream as fluffy as cappuccino froth. This is the conclusion of a study published on Wednesday. In 2014, more than ten years after its launch, the European Space Agency (

In orbit around the Earth for more than twenty years (for the oldest modules), the ISS is aging. In a few years, it will therefore be abandoned by the astronauts. But what will happen to the structure? On November 2, 2000, NASA astronaut Bill Shepherd and the two Russian cosmonauts, Yuri Gidzenko

A team of astronomers announces that they have identified several dozen primitive galaxies that are already very mature for their age. An astonishing discovery, which suggests that these objects developed faster than expected. Most galaxies formed when the Universe was still very young. The Milky W

The European Space Agency (ESA) on Tuesday, October 27 signed a memorandum of understanding formalizing its collaboration on the Lunar Orbital Platform-Gateway, the future outpost in NASA lunar orbit. NASA has set a goal of returning humans to the Moon as early as 2024 as part of its Artemis progra

An analysis of the teeth of Sue, one of the most famous T-Rex in the world, seems to confirm the idea that the animal suffered from an infection parasite at the end of its life. It may have been this infection that led to his death. Sue is one of the largest T-Rex ever found and it is also the most

NASA recently opposed a companys request to build a mega-constellation of satellites, citing concerns about potential collisions. This is the first time that the space agency has publicly opposed such a request for market access. To enable a better internet signal, we need to go through the sky. In

Among the most extreme exoplanets discovered to date are worlds orbiting so close to their star that some regions are just oceans of molten lava. Astronomers recently analyzed the weather cycle of one of these planets. Our planet might seem inhospitable in some places, at some times, but bless heav

The finding of Starlink satellites aimed at connecting the Earth is still far from complete. Nevertheless, SpaceX has already mentioned its desire to apply the same type of technology to the planet Mars. However, this project could be even more crucial than the one concerning our planet! After Eart
