According to the Russian news Agency, Tass #Roscosmos is contemplating their own version of the " Starlink " internet satellite system. The report indicates it should go on line in 2025. (Me: "raises a skeptical eye" We will see...) https://tass.com/science/1535097

One last photo highlight of the week: the fearsome 1,800 metre high Eiger Nordwand as seen from Kleine Scheidegg, the famous & appropriately named Hotel Bellevue in the foreground.

This mountain has lived in my dreams since I was young, reading of the first British ascent by Chris Bonington & Ian Clough in 1962. It’s always a thrill to see it in person.

Also thinking of Ueli Steck & his stunning 2h23m solo ascent in 2015, 18 months before his death on Everest.

Heart-shaped pendant with a lock of hair from Marie Antoinette. If this is her hair, it must have been presented before the abortive flight to Varennes in 1791, when Marie's hair allegedly went white overnight.

Is it possible for a person’s hair to go white overnight? Researchers found that hormones produced in response to stress can deplete the melanocyte stem cells that determine hair color. But there’s no scientific evidence that this can happen within hours due to trauma. #histodons

If you're new at this

Another design consideration re: Mastodon is that it works well for ephemeral asynchronous communications, but for many reasons should not be counted on as an archival resource. Media attachments are periodically purged and may not be available after a week, or a month, etc. While some servers may try to preserve content forever, this may be costly and unsustainable. Creators, researchers should treat this as an ephemeral resource and make provisions for self-archiving anything important.

Decently deep image considering that it was taken with an untracked iPhone 11 in night-mode (30 sec exposure) & from a suburban garden in one of the most densely-populated parts of Europe, the Randstad 🌃

The crisp clear skies & lack of Moon tonight obviously helped 🤷‍♂️🙂

A big thanks for the warm welcome to Mastodon! I’ll be posting more of my favourite images of the #ScottishHighlands over the next few days. This is one of my more popular photos - sunrise over Loch Avon in the Cairngorms.

Is there a #teachingcommunity here ? Would love to join #teachers #teachingassistants #learning

After many years in psychology, I happen to publish in Nature! (Astronomy) 🙂 #Science

We will try to let you see the stars with your ears! 💪

Hello #ScienceMastodon! I am an Associate Professor in Psychology at University of Padua. I study #hearing #perception and the relationship between #perception and #cognition I also developed tools for research in #hearing #perception (one new coming out soon). I support #openscience

In my free time #kayak and #rowing If you pop by here I’ll take you paddling in the #venice #lagoon

Here's a really nice introduction article to the #astronomy field of research I am currently working in.

You've heard of Gravitational Waves (GWs) - but did you also know there is a GW spectrum - and much like the EM spectrum, different sources produce different frequencies of GWs.

The GWs we've so far discovered are generated by stellar mass black holes and neutron stars, but the research I am involved with is searching for GWs generated by supermassive black holes (SMBHs) - found in the hearts of galaxies. These SMBHs give off their gravitational radiation as galaxies merge and collide.

Though these are nanohertz frequencies and have wave periods lasting not seconds, but decades! So, we can't use terrestrial detectors to discover them. Instead, we use pulsars located around the Galaxy - each as an analogue to a giant interferometer arm.

This Thursday I am submitting my Master's Thesis on this very topic! For the last 12 months I have assessed 10 new millisecond pulsars to see how they improve the Parkes Pulsar Timing Array's sensitivity to detecting these GWs.

Hello! It's great to be here. I'm a PhD student at Rutgers at the moment, and this will be my "very professional" mastodon account! I'm currently working with moon rocks, specifically meteorites, specifically-specifically lunar breccias.

Look up tonight! The Northern Taurid #meteor shower is expected to peak with the possibility of #fireballs. More on EarthSky: https://earthsky.org/astronomy-essentials/taurid-meteors-all-you-need-to-know/ and SPACE.com: https://www.space.com/nothern-taurid-meteor-shower-peaks-saturday-nov-12-2022

It's not the most active shower of the year, but you might get lucky if you have very dark skies and clear weather 🌠 #meteorshower #taurids #cometencke #skywatching
