Why was the Search for #Extraterrestrial Intelligence (#SETI) 👽 unsuccessful so far ?

#Life 🦠 appeared pretty much as soon as it could, right when the #oceans formed and our #planet stopped being a molten 🌋 hellscape. That might have been as early as 3.7 billion years ago. But #intelligent life appeared basically yesterday—what we identify as anatomically modern humans arose about 120,000 years ago. https://arstechnica.com/space/2023/05/were-essentially-alone-in-the-universe-and-thats-ok

Early action from regarding mining new frontiers would demonstrate leadership, signal that Canada welcomes innovation and investment, and support the transfer of technology between sectors. The is one of Canada’s most R&D intensive.
Mining in northern, remote, and isolated communities and in 🌌 face common challenges related to exploration, infrastructure development, and operating in harsh and remote environments. The minerals sector is taking advantage of such as , remote sensing, and aerial and earth technologies to create safer, cleaner and more efficient operations. https://natural-resources.canada.ca/sites/nrcan/files/CMMP/CMMP_The_Plan-EN.pdf

In 2017, I crocheted myself a solar system costume. The headpiece is mounted on a bike helmet for stability (I got that tip from some folks who build showgirl costumes). The tunic is made from fine black linen yarn, very matte, very tedious, much like I imagine space is most of the time. The planets are made using an online sphere pattern generator, so that I could vary the sizes in a predictable way; they are strung on a fishing line with beads, and suspended from an elastic collar, also crocheted. They are also kept in place with a beaded "asteroid belt", located between Mars and Jupiter, of course. Photographed at Manhattan Beach Pier. All second-hand yarns, though I had to ask around for enough yellow to make the sun so large. #solarsystem #crochet #costume #planets #sun #astronomy #planetary #yesplutotoo

Going to talk about planetary differentiation in today's bit of teaching with the lens of one of my favourite-ever arXiv papers: what happens if you replace the Earth with an equal mass of blueberries? https://arxiv.org/pdf/1807.10553.pdf

LeftistLawyer, to world

From the Law & Political Economy blog. Today's must read:

"Fredric Jameson once noted that 'it is easier to imagine the end of the #world than the end of #capitalism.'

That’s the famous version. What Jameson wrote in context is, 'Someone once said that it is easier to imagine the end of the world than to imagine the end of capitalism. We can now revise that and witness the attempt to imagine capitalism by way of imagining the end of the world.'

#ClimateChange offers a vivid illustration of Jameson’s point. Through climate change, the end of the world as #humans have known it is now imaginable to an unprecedented degree. And capitalism, viewed through the lens of climate change, appears to some observers to be a terminal #planetary #disease."

Hi fediverse and #welcome to #Astrodon
Time for a new #introduction after the latest #twittermigration I’m a #planetary scientist studying the #atmospheres and volatiles on the #Moon. I haven’t posted much lately because of a #CareerChange from @jhuapl where I worked in strategic leadership as the Chief Scientist for #exoplanets to @nasagoddard where I’m working in the Planetary Systems Laboratory https://science.gsfc.nasa.gov/solarsystem/planetarysystems/

Try zooming in on Valles Marineris. Reminds me of the procedurally generated planets in Space Engine but it's actual streamed accurate data.

Now that I have a new home on solarsystem.social, here's a new #introduction!

I am a #planetary scientist working at the Institut de Physique du Globe de Paris (#IPGP) in France. My research uses the #gravity field, #topography, and #MagneticField of the planets to decipher their internal structure and geologic evolution. My favorite terrestrial body is the #Moon, but I also work with #Mercury, #Venus, and #Mars. Soon I will need to learn about #Psyche and the icy satellites of #Jupiter!

Using impact as a dating tool, Institute Research Scientist Alexander Morgan has determined maximum timescales for the formation of valley networks shaped by running water.

The Andromeda Galaxy obvi gets all the attention for deep-sky objects in the #constellation #Andromeda (including in our most recent #podcast), but I also appreciate NGC 7662 aka Blue Snowball Nebula!

This planetary nebula is located ~2500 LY from earth!

Giant gas #planets can be agents of chaos, ensuring nothing lives on their Earth-like neighbors around other #stars. New studies show, in some #planetary systems, the giants tend to kick smaller planets out of orbit and wreak havoc on their climates.

The LPI #Lunar Summer program is open again for grad students (from anywhere in the world) interested in lunar science and exploration.

I was part of this program back in 2009, which was a lot of fun, despite the fact that we watched Constellation get cancelled from under us. This should be a much better time to get into lunar exploration, and a rare opportunity for non-US students to get their foot into the NASA door.

Was only able to sharpen it up a tiny bit more. Bad seeing conditions that evening but I'm happy with it since I wasn't even planning on doing any planetary astronomy/astrophotography this year.
