Glows will surround helicopters flying in the Mars sky
Ingenuity will have been the very first. But there will undoubtedly be others. Helicopters in the skies of Mars. And they just might… illuminate the Martian atmosphere with a purple…
What are these dark “finger-like” structures seen in solar flares?
Twenty years that astronomers wonder what really hides behind the dark structures that seem to fall towards the Sun during an eruption. The hypothesis of a consequence of the magnetic…
End of the problem for Perseverance who sets out again to attack the Martian rocks!
The Perseverance rover drilled again into Martian rock several days after encountering a problem with its storage mechanism. NASA carried out a cleaning of the carousel of the rover before…

James Webb Space Telescope: international scientific collaboration at its peak
The arrival at the Lagrange L2 point of the James-Webb space telescope is the culmination of an epic launched more than 30 years ago. The new high-performance observatory has brought…
The Great Eta Carinae A Eruption was modeled by NASA with help from Hubble and Chandra
NASA teams have modeled in 3D the phenomenon of the Great Eruption of the star Eta Carinae A, in the Eta Carinae stellar system. Having taken place in 1838, the…
This Saturn moon would also hide an ocean under its surface
Around Saturn there was already Enceladus and Titan. Among the moons of the ringed planet that hide a liquid ocean under their surface, it will now probably also be necessary…
