JWST Might Have Imaged a Hycean World for the First Time, With a Hydrogen-Rich Atmosphere and a Deep Planet-Wide Water Ocean
Despite its great oceans, Earth is not really an ocean world. It has less water than icy moons such as Europa and Enceladus, a relatively thin nitrogen-rich atmosphere, and vast continents that rise above sea level. A true ocean world would have no continents, a warm sea hundreds of kilometers deep, and a thick hydrogen and water-rich atmosphere. They are known as hydrogen-ocean planets or hycean worlds. While we’ve long thought they exist, the James Webb Space Telescope may now have found one.

'Artificial star' helps test satellite navigation systems (photo)
The builders of star trackers need to test their tools before launching them aboard satellites. And that's where star simulators come in handy.
Webb discovers methane and carbon dioxide in atmosphere of K2-18 b
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.

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.
