The interiors of rocky #exoplanets may have large quantities of #water.

But how large are those quantities and can they be estimated?

Assuming planets have four different layers enables such an estimation.

Given an iron core, a rock mantle, a high-pressure ice layer, and a surface ice/water layer, water fraction of planets can be produced by modelling their structures and comparing them to observed planetary properties.

The results show that #Proxima Centauri b, Ross 128 b, Teegarden’s b and c, GJ 1061 c and d, and TRAPPIST-1 e may have an extended liquid water reservoir.

Furthermore, extremely high water content of the exoplanets Kepler-62 f, Kepler-1652 b, Kepler-452 b, and Kepler-442 b suggests that these #planets may maintain a water vapour #atmosphere and may in fact be examples of larger ocean worlds.

Il y a 9 ans, j'étais à Baïkonour pour le décollage de Thomas Pesquet pour sa mission #Proxima.
Oui, à droite, c'est la fusée à un peu plus de 1 km.
Incroyable moment !

C'était jouable. Les individus de son espèce vivaient un milliard d'années en moyenne, cela représentait pour elle l'équivalent d'un quart de sa vie. Elle enfila son maillot jaune et commença à pédaler. (2/2)

‘The pie is big’: French railways open up to European rivals.

This summer, a high-speed train from Paris to Marseille ran under Italian colours for the first time, the latest dent in national operator SNCF’s dominant position in French rail.

Italian and Spanish high-speed train operators and start-ups challenge the dominance of state-owned SNCF.

If it wasn't already clear, #Proxima b and d can now be considered confirmed #planets because they have been clearly identified in independent near-infrared Doppler spectroscopic data.

Если вы настраивали отказоустойчивый кластер Postgres, то сталкивались с необходимостью перенаправления пользовательского трафика на пишущий узел после аварии на основном узле и переключения на резервный. Мы разработали расширение Proxima, которое снимает необходимость в настройке и администрировании дополнительного программного обеспечения. Разработчик программного обеспечения Postgres Professional Тофиг Алиев расскажет, как мы делали Proxima, какие архитектурные решения заложены в расширение, почему мы выбрали именно такой подход. Разберет тонкости реализации, которые позволили нам обрабатывать более 10 тысяч одновременных клиентских сессий. Рассмотрит примеры использования и ответит на вопросы.

Proxima Centauri is our nearest stellar neighbor and is known to be a very active M dwarf #star.

Known to host a potentially #habitable #planet, the star #Proxima exhibits very active #flare activity in optical wavelengths.

Depending on the energy and frequency of these flares, nearby planets in the habitable zone might be rendered uninhabitable as the flares strip planetary atmospheres of necessary ingredients such as ozone and water.

Extremely Large Telescope should be able to gather spectra not just on #exoplanets that transit their #star, but also from non-transiting exoplanets via reflected starlight.

It should be possible to make clear and accurate distinctions for nearby star systems.

For the closest star, #Proxima Centauri, we could detect #life on an Earth-like world Proxima b with only 10 hours of observations.

https://phys.org/news/2025-03-extremely-large-telescope-hints-life.html

The upcoming extremely large telescopes will provide the first opportunity to search for signs of #habitability and #life on non-transiting #terrestrial #exoplanets.

For the most accessible nearby target, #Proxima Centauri b, we may be able to rule out a sub-Neptune #atmosphere in as little as a single hour of observing, and some #biosignature disequilibrium pairs may be accessible in 10 hours.

The closest #star system to the Sun is the Alpha #Centauri system.

Of the three #stars in the system, the dimmest -- called #Proxima Centauri -- is actually the nearest star.

The bright stars Alpha Centauri A and B form a close #binary as they are separated by only 23 times the Earth- Sun distance - slightly greater than the distance between Uranus and the Sun.

Tiny gram-scale #interstellar probes pushed by laser light are likely to be the only technology capable of reaching another #star this century.

This requires a laser beamer to boost a few grams to relativistic speed, lasersails robust enough to survive launch, and terrestrial light buckets big enough to catch optical signals.

The mission is to fly by the potentially #habitable world #Proxima b, with a large autonomous swarm of 1000s of tiny probes.
