The Ingenuity Experimental Martian Helicopter contains a small sample of fabric from the Wright Flyer, the aircraft in which the Wright brothers performed the first controlled, powered flights of the Earth. history of aviation, NASA revealed on Tuesday. On Mars for a little over a month, the Americ

Large Low Shear Velocity Provinces (LLSVP) are among the largest and strangest of all isolated structures on Earth. Where do they come from? According to new simulations, it could be the remains of Theia, this protoplanet to which we owe the Moon. Two huge drops of dense rock lurk deep in the lowes

The US space agency recently sent the Perseverance rover to the Red Planet to collect soil samples. However, it is not able to determine whether life will be present there or not. The samples will have to be sent back to Earth for analysis. What is Perseverance looking for? The Perseverance rover a

Twelve bottles of Petrus spent a few months on board the International Space Station, accompanied by a few vines. The tasting notes were unveiled this Wednesday at the town hall of Bordeaux. Result:weightlessness did not ruin the wine, and seemed to energize the plants. A little over a year ago, th

Two years ago, the Event Horizon Telescope collaboration revealed the incredible first-ever image of a black holes shadow. These same researchers have just published a new portrait of the object, revealing new details related to its magnetic field. M87 is a black hole 6.5 billion times more massive

Europe, led by France and Italy, calls for a coordinated approach in a bid to compete with SpaceX, a leader in rocket launches, during the next decade. But can she really do it? Towards a more aggressive spatial strategy Concerned by the ever-increasing power of SpaceX, the European Union is aiming

Are we alone in the galaxy? Many wonder. In recent decades, some have even tried to signal our presence to possible extraterrestrials. Here are the different messages sent. We start in 1962. At the time, Soviet researchers pointed a radio transmitter at Venus and greeted the planet in Morse code. T

According to a new study, the global ocean of the moon Enceladus is not homogeneous. Currents very similar to those on Earth could flow there under twenty kilometers of ice. Enceladus, Saturns sixth largest moon, is a small ball of ice 500 kilometers in diameter. Despite its size, the object has at

While collisions between satellites are so rare that only one has occurred in history, the multiplication of these objects in orbit increases the risks. NASA and SpaceX have therefore entered into an unprecedented agreement. Both parties will thus collaborate to avoid potential future collisions. M

On our planet, the remains of the first forms of life have almost entirely disappeared. But on cold, dry Mars, they could be buried right under our feet. A little over a month ago, Perseverance successfully landed on Mars. Since then, the teams have been working to check the rovers instruments. Res

The list of objects posing a potential threat to Earth is quite short, and for a time, the asteroid Apophis was one of them. But not anymore. The object has indeed just lost its  potentially dangerous  status for at least the next 100 years, according to new observations. Astronomers have been moni

Wrongly considered a primordial explosion, the Big Bang does not represent a starting point, but the horizon line beyond which we cannot go, and from which were born the notions of space and time. What do we know about this primitive era? The discovery in 1929 by Edwin Hubble that the Universe was

Several researchers are campaigning for sending a mission to Uranus and Neptune. Such a project could reveal a treasure trove of information about the two ice giants, but also allow astronomers to peer much deeper into the universe. Poor Uranus and Neptune! The only portraits we have of these outer

Light from an explosion in the early universe illuminated an intermediate-mass black hole. This new discovery could expand our understanding of the formation of these enigmatic celestial objects. There are three classes of black holes in the universe. On one side we have the stellar mass objects.

At the center of the Abell 2261 galaxy must be a black hole as massive as several billion suns. However, the researchers do not detect any sign of the presence of such an object. Is it just inactive? Has it been screened elsewhere? The investigation is ongoing. Missing black hole We have known for

A team of astronomers announces the discovery of a new exoplanet:a super-Earth located less than 36 light years from our system. On the other hand, this a priori rocky world does not evolve in the habitable zone of its star. To detect exoplanets, astronomers generally rely on two methods:transit an

Researchers relying on the Gran Telescopio Canarias announce that they have isolated the most densely populated cluster of galaxies in formation in the early universe. Their work is published in the Monthly Notices of the Royal Astronomical Society. Galaxy clusters are associations of several galax

Gliese 486 b could help astronomers better understand the atmospheres of rocky planets. This world will soon be targeted by the James Webb Telescope, which is still scheduled for launch in October. Gliese 486 b is an exoplanet recently discovered by researchers at the Max Planck Institute for Astro

The loss of a lucrative contract with the Pentagon forces Blue Origin to postpone the inaugural launch of its new launcher:the New Glenn. Even if it is lagging behind, Blue Origin, created in 2000 by Jeff Bezos (Amazon), is today the main competitor of SpaceX. For several years, the company has bee

Last July, C/2020 F3, nicknamed comet NEOWISE, was visible to the naked eye in the French sky. To locate it, it was enough to observe the claws of the Big Dipper. Will we be able to enjoy such a show again this year? The object that interests us today is Comet Leonard, cataloged C/2021 A1, discover
