A new investigation by an international team of astronomers using data from the NASA/ESA/CSA James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.

Meteosat Third Generation: painting the full picture
Video: 00:00:14
In a significant leap forward for meteorology, the preliminary data obtained by Meteosat Third Generation’s two instruments, the Flexible Combined Imager (FCI) and the Lightning Imager (LI), were successfully combined today for the first time – highlighting their complementary capabilities. This first set of animations gives us a preview of the system’s future impact.
Astronaut Frank Rubio breaks US record on way to spending a year in space

Mysterious moonquake traced to Apollo 17 lunar lander base
A reanalysis of Apollo 17 seismic data has revealed that the Apollo 17 lunar lander base is creating its own moonquakes.
Galileo becomes faster for every user
ESA satnav receiver vans – driving between the busy heart of Rotterdam, quiet countryside, and the Agency’s ESTEC technical centre – have confirmed that Galileo signals now provide a first position fix more rapidly, while also offering improved robustness in challenging environments and streamlined access to time information.
Kombucha: Ally for Moon and Mars
ESA is testing kombucha cultures, famous for their fermentative properties and potential health benefits, to assess their resilience in space. These cultures hold great promise for supporting humans on the Moon and Mars.
Polaris is the Closest, Brightest Cepheid Variable. Very Recently, Something Changed.
When you look up in the night sky and find your way to the North Star, you are looking at Polaris. Not only is it the brightest star in the Ursa Minor constellation (the Little Dipper), but its position relative to the north celestial pole (less than 1° away) makes it useful for orienteering and navigation. Since the age of modern astronomy, scientists have understood that the star is a binary system consisting of an F-type yellow supergiant (Polaris Aa) and a smaller main-sequence yellow dwarf (Polaris B). Further observations revealed that Polaris Aa is a classic Cepheid variable, a stellar class that pulses regularly.
The Closest Black Holes to Earth are Probably Hidden in This Nearby Star Cluster
In the constellation Taurus, there is a cluster of a few hundred stars known as the Hyades. The cluster is just 150 light-years away, and it could be harboring a stellar-mass black hole.

Every Night and Every Morning, the Moon Rumbles With Tiny Quakes
The Moon was geologically active between 3.7 and 2.5 billion years ago, experiencing quakes, volcanic eruptions, and outgassing. Thanks to the Moon being an airless body, evidence of this past has been carefully preserved in the form of extinct volcanoes, lava tubes, and other features. While the Moon has been geologically inert for billions of years, it still experiences small seismic events due to tidal flexing (because of Earth’s gravitational pull) and temperature variations. These latter events happen regularly and are known as “moonquakes.”
