Live and recent posts from across the Fediverse tagged #planetary, aggregated by home.social.

  1. "Pluto-like world’s thin atmosphere poses a mystery" by @cosmiclog / @alanboyle - A thin atmosphere may have been observed around a #KuiperBelt object a quarter Pluto's size. As the minor planet crossed in front of a star, telescopes saw light go out and come back slowly rather than instantly. And since Alan is author of "The Case for Pluto" book, he mentions a recent public discussion among politicians about reclassifying Pluto as a planet. cosmiclog.com/2026/05/08/pluto #astronomy #planetary #science

    Congratulations to Heike Rauer! 🎉

    I had the pleasure of experiencing her work firsthand in a colloquium at my former institute while I was still a student, and I remember her as an outstanding #planetary scientist. A very well-deserved recognition!

  8. Hace tiempo que no publico nada de lo que pude observar con el telescopio. Acá les dejo unas imagenes planetarias que tomé en setiembre (Saturno) y fines de febrero (Júpiter y la Luna a 30º de altura). Las tomé con una Celestron NexImage 5 a foco directo prestada, con una escala de placa nativa (sin filtros ni barlows) de 0.38"/px y un seeing regular #kasai #jscope80l #japan #telescopio #refractor #telescope #planet #planeta #saturn #jupiter #saturno #astronomía #astronomy #planetary

  9. What The Soviets Found On Venus

    • interesting vid to watch
    • learn about Soviet determination
    • unreal atmospheric pressures
    • temperatures higher than an oven in the atmosphere
    • braking systems for probes in water like behaving heavy Venus atmosphere
    • Venera 13 had a mic onboard!
    • Venus sounds horrifying (at least to my little cousin whose listening in as I make this toot) ;)
    • they had sent 14 probes at least to Venus

  10. 🌏 Why are only a few #planets suitable for life? And why is Earth one of them?

    Dr. Rob Spaargaren, together with his international team of astronomers, answers these questions in a new paper.

    It may have consequences for the search for life elsewhere.🔎

  11. This research fills a critical "missing link" in #planetary science, offering a comparative lens to understand the history of our own Solar System—specifically the #Kuiper Belt and the Moon's cratering—while helping scientists determine if our system's chaotic evolution is unique or a cosmic norm.

    These are the people who really understand #risk. 2 degrees by 2050. Mind you - average over 2023-25 was 1.48 degrees.

  16. Solar pacifiers: Influence of the planets may subdue solar activity
    Researchers at #HZDR find the Sun’s activity cycles can be traced to the tidal pull of planets – and that this #planetary “sync” naturally reins in #solar activity.

  17. Supplies of #dissolved #oxygen in bodies of water across the globe are dwindling rapidly, and scientists say it's one of the greatest risks to Earth's life support system.

    Just as atmospheric oxygen is vital for animals like ourselves, dissolved oxygen (DO) in water is essential for healthy aquatic ecosystems, whether freshwater or marine.

    With billions of people relying on marine and freshwater habitats for food and income, it's concerning these ecosystems' oxygen has been substantially and rapidly declining.

    A team of scientists is proposing that aquatic deoxygenation be added to the list of '#planetary #boundaries', which in its latest form describes nine domains that impose thresholds "within which humanity can continue to develop and thrive for generations to come."

    So far, the planetary boundaries are
    climate change,
    ocean acidification,
    stratospheric ozone depletion,
    interference with the global phosphorus and nitrogen cycles,
    rate of biodiversity loss,
    global freshwater use,
    land-system change,
    aerosol loading, and
    chemical pollution.
