The Very Large Telescope (VLT) has just achieved the feat of photographing two planets in orbit around a Sun-like star. This star system is about 300 light years from Earth. If today there are more than 4,000 worlds in more than 2,800 planetary systems, remember that all these planets have been loc

Recent analysis of several lunar craters suggests that the Earth-Moon system suffered a particularly violent episode of bombardment 800 million years ago. 40 to 50 trillion metric tons of meteorites hit the Earth-Moon system 800 million years ago, study finds. It was 30 to 60 times the amount of ma

Samples from the asteroid Ryugu, captured by Japans Hayabusa2 probe, are expected to land in Australia on December 6, local time, agency officials announced yesterday. space of the two countries. Standing on the surface of an asteroid, only the movie Armageddon could allow us to imagine it. But a f

In a few weeks, an asteroid about 50 meters in diameter will rub shoulders with Earth less than 75,000 kilometers away. Rest assured, the object poses no threat. Nevertheless, it remains large and close enough to be considered potentially dangerous by NASA. Things are happening above our heads! For

As part of a recent exchange, NASA administrator Jim Bridenstine discussed the various upcoming projects, mentioning in particular the Mars 2020 and Artemis. He also took the opportunity to take stock of the various preparations underway as part of a future human exploration of the red planet. As ​

An extensive cosmological study has led to the creation of the largest 3D map of the Universe ever made. This is the result of the analysis of several million galaxies and other quasars. This work thus traces a more continuous history of the Universe and offers a better understanding of the mechanis

Three joysticks used to fly the ship carrying astronauts to the Moon on the Apollo 11 mission have sold for over $780,000 at auction . Much to the chagrin of NASA. Two attitude control sticks and a manual translation control of the Columbia module of the Apollo 11 mission were auctioned off this Sa

A German citizen discovered the largest stony meteorite ever found in the country. For the German Aerospace Center (DLR) this is a sensational find! A 30 kg meteorite! Blaubeuren is the name of the stony meteorite that a German discovered in his garden. With its dimensions of 28x25x20 cm for a weig

NASA will deploy a 150-meter-wide balloon into the stratosphere. The goal:to observe the stellar feedback process in the infrared. Its launch is scheduled for December 2023. NASA is currently developing a large-scale mission named ASTHROS (short for Astrophysics Stratospheric Telescope for High Spe

A Martian meteorite found on Earth 20 years ago will travel on NASAs Mars 2020 mission. The American agency must indeed rely on it to calibrate several of its instruments. It is the Natural History Museum in London which, since its discovery in Oman in 1999, has kept this Martian meteorite called S

If all goes as planned, NASAs American Perseverance rover will land on Mars on February 18, 2021. During its descent phase, it will be guided autonomously to the safest possible landing site thanks to ultra-accurate maps. Although NASA, to date, has still managed to land eight machines on Mars, the

Virgin Galactic has just presented the interior of its ship that will allow passengers to float in space during suborbital travel. On the other hand, to afford a ticket, you will have to wait a little longer. Four years ago, the company Virgin Galactic, created by the famous Richard Branson, presen

Like all other objects in the Universe, stars are not eternal. They eventually die out, replaced by others that will take their place. However, not all stars suffer the same fate. Depending on their mass, their end can be more or less violent and chaotic. All stars do not have the same mass and ar

If the Universe has different civilizations, each with their own characteristics, they should however share a common point:the need for energy. According to the technological scale established by Russian physicist Nikolai Kardachev, a Type III civilization is capable of harnessing all the energy of

During the month of February, the Martian orbit will welcome three new arrivals from Earth:the UAEs Hope space probe, which successfully completed its orbital insertion on Tuesday February 9; the space probe (equipped with a lander) Tianwen-1, which also successfully placed itself in orbit today (We

Included in the standard cosmological model, Einsteins theory of general relativity (and its solutions) is the framework allowing today to describe the parameters and the evolution of the Universe. However, Einstein did not always buy into the idea of ​​a dynamic universe. This is why, two years aft

The solar wind is a flow of particles emitted by the Sun that travel throughout the Solar System. First proposed in the 1950s by University of Chicago physicist Eugene Parker, solar wind is visible in the halo around the Sun during an eclipse and sometimes when particles hit Earths atmosphere; like

Communicating with extraterrestrial civilizations is an old dream of science fiction writers, yet scientists have been trying hard to establish communications over the past few decades. If for the moment we have no clues concerning the potential existence of extraterrestrial intelligent life, astrop

After the formation of the Solar System, Mars was not very different from Earth. With an atmosphere and a magnetic field, the Red Planet potentially sported rivers and verdant plains. However, over time, the situation has deteriorated to the point that today the Martian atmosphere, almost non-existe

In the catalog of cosmic objects, neutron stars are certainly among the strangest elements. Products of the collapse of massive stars, the precise composition of these extremely dense objects is still unknown to astrophysicists. Certain particular forms of neutron stars, called pulsars, are of great
