Peeking at the Earth

As the Artemis II crew came close to passing behind the Moon and experiencing a planned loss of signal, they captured this image of a crescent Earth setting on the Moon’s limb.

A New View of the Moon

Wowzer!

Earthset captured through the Orion spacecraft window during the Artemis II crew’s flyby of the Moon.

Posting in the Fediverse since last week: @uksolarphysics! 🇬🇧 ☀️

The UK Solar Physics community (UKSP) is a Specialist Scientific Group affiliated to the Royal Astronomical Society. They regularly provide relevant news and nuggets both to their members as well as the international solar physics community at large via https://uksolphys.org/

If you're interested in the research of the Sun, our closest star, at all, consider following them for their announcements either at https://uksolphys.org/news/recent-news-summary/, or via their UKSP newsletter (mailing list), or now directly here via their Mastodon account @uksolarphysics

Maybe don't expect them to interact a lot, but if you *are* here for their very useful announcements, it is now really easy to follow and also boost those. So, a warm welcome to @uksolarphysics 🌞

Time for a change.

Since late last year, I've only shared my photos from the 21 days we spent in Iceland in Sept/Oct 2025.

I also have over 150,000 photos from other trips there in 2014 (Sept), 2015 (July/Aug), 2016 (Mar and Nov), 2019 (Feb), 2021 (Oct/Nov), and 2024 (Jan). All of the best ones have been edited and signed. From now on, I'll be sharing photos from all years.

📣 Neues Titelbild 🖼️

Das Diagramm zeigt die Ergebnisse der bisher empfindlichsten Suche nach kontinuierlichen Gravitationswellen.

Forschende des @mpi_grav haben dafür die von Freiwilligen gespendete Rechenleistung von @einsteinathome eingesetzt, um genauer als je zuvor in Daten von @LIGO nach den schwachen bislang noch nie beobachteten Signalen zu suchen.

Als erste haben sie alle „hardware injections“ (künstlich in die Daten eingefügte Signale) aufgespürt.

Weil Rechenleistung und Effizienz der Suchmethoden entscheidend sind, geht das Team geht davon aus, dass ihre Ergebnisse mit den noch nicht veröffentlichten Untersuchungen von LIGO-Forschenden mithalten können, obwohl letztere noch genauere Messdaten haben.
