Just minutes after the two American astronauts landed on Sunday, several pleasure boats crowded around the capsule. NASA and SpaceX intend to put in place the necessary means to prevent this from happening again. You may have followed it live. Bob Behnken and Doug Hurley landed off Florida on Sunda

Researchers have just identified the best place on Earth to observe the stars through a telescope. The challenge ? This place located in Antarctica is one of the coldest and most remote on the planet. To observe the stars on our small scale, we just need to get as far away as possible from any sour

On Mars, many valleys were carved by melting subglacial water, not free-flowing rivers as previously thought, according to a study published on Monday. Since the discovery of thousands of Martian valleys decades ago, the prevailing assumption has been that all of these structures were carved out by

As part of its future crewed missions in collaboration with NASA, SpaceX will be able to reuse its own capsules. This understanding between the two organizations was expected, but not so quickly. A successful landing for NASA This Sunday, NASA astronauts Bob Behnken and Doug Hurley splashed down at

A fungus found in Chernobyl reactor number 4 could be the subject of a revolution in terms of space conquest. Indeed, it is a question of using the latter in order to build anti-cosmic radiation shields. This innovation could be used for the International Space Station (ISS) but also and above all i

Recently, a company announced a contract with the United States Department of Defense. The goal? Develop a station or rather an autonomous space outpost that could be put into orbit in 2022. A scalable and autonomous space station In a context of spatial tensions with China and Russia, the United

Based on a recent study published in The Astrophysical Journal , up to seven habitable planets could orbit a star under certain conditions. In our system, it would also seem that Jupiter played the spoilsport. Discovered in 2017 39 light years from Earth, the TRAPPIST-1 system captured our imaginat

A team of astronomers announces the discovery of a veritable cloud wall thousands of miles long moving around Venus. This is the first time that such a phenomenon has been observed in the Solar System. Venus is a real atmospheric laboratory where everything goes to extremes. And for good reason:its

The dwarf planet Ceres is an oceanic world, with liquid, salty water flowing beneath its surface, according to a series of studies published on Monday. Discovered by Giuseppe Piazzi in 1801, Ceres is the largest object in the asteroid belt, between Mars and Jupiter. This dwarf planet, once conside

Discovered a handful of years ago, exoplanet K2-25 b is giving planet formation specialists a hard time. Its main feature? Its astonishing density for its size which could challenge theories on the subject! A real headache As the NASA exoplanet catalog states, K2-25 b is a Neptune-like exoplanet or

The US Space Force has just published a 41-page doctrine. The document details the basic principles on which the different action plans of this new military branch in space will be based. Just over two years ago, US President Donald Trump declared his intention to develop an American space force. S

This summer, dont miss the Perseid meteor shower, with peak activity scheduled for the night of August 12 to 13. Nearly a hundred meteors could split the sky every hour. Look up! Its one of the most anticipated astronomical events of the summer:the Perseid meteor shower. Already visible in the nigh

The American probe Juno has just revealed to us a new type of lightning in the upper atmosphere of Jupiter. At these altitudes, ammonia hailstones can also form, playing a key role in the atmospheric dynamics of the giant. Since the passage of the American probe Voyager 1 in the Jovian system in 1

NASA has again just partnered with the SETI Institute. The goal:to ensure that the current and future missions of the American agency comply with planetary protection standards. Protect and protect ourselves When exploring a planet or moon, the problem of microbial contamination must arise. Our ger

A white dwarf star that fell victim to a partial supernova thousands of years ago is now traveling the galaxy at over 900,000 km/h. White dwarfs are the cores of medium-sized stars, like the Sun, that have expelled all of their outer layers. You then get a stellar corpse, cold and dark, the size o

C/2020 F3, nicknamed comet NEOWISE, is currently visible to the naked eye in the French sky. To spot it, all you have to do is observe the claws of the Great Bear. A fascinating spectacle that wont last forever! If comets ATLAS and SWAN were to be the stars of this summer, it is ultimately NEOWISE

Astronauts Bob Behnken and Doug Hurley, members of SpaceXs first-ever crewed mission to the ISS, will return to Earth on August 2. Landing is planned in the Atlantic. On May 30, SpaceX propelled astronauts Bob Behnken and Doug Hurley to the International Space Station (ISS). A historic takeoff for

Known since ancient times, comets are leftovers from the formation of the Solar System. Composed of a core a few kilometers in diameter, these revolve around the Sun within the Kuiper belt. How to define a comet and where does this luminosity that characterizes it come from? What is a comet? At the

A new document published by the Chinese space agency brings new details about the Tianwen-1 mission, which plans to send a rover to Mars. If no official date has yet been communicated, the launch could take place this Thursday. On July 19, a Japanese rocket launched Hope, the first Mars mission fro

Astronauts Bob Behnken and Chris Cassidy have each just completed their tenth extravehicular activity (EVA) from the ISS. Only two other astronauts have done so. Bob Behnken, who arrived on the ISS on May 31, and Expedition 63 Commander Chris Cassidy each completed their tenth spacewalk this Tuesda
