The IIgs was my dream computer. I had the brochure for it and pretty much looked at it everyday for years!

It is sooo good!

Excited to be making the space nerd pilgrimage: catching the midnight showing of Interstellar being re-released in IMAX 🍿🥤🚀🪐

Half the theater look like they weren’t born yet when the movie first came out but nevertheless so excited for this!

And to give you a scale of the signal power .... the signal from your home wi-fi is billions of times stronger (I think ~10 billion IIRC) than the signal Earth receives from Voyager spacecrafts. It's incredibly feeble, so detecting it is a big feat!

Well done to this team!

Why this is neat?

Well, the Voyagers are so far away (human's furthest objects) that we need the biggest telescopes in the world (the Deep Space Network) to normally communicate with them. Those are big 70m dishes, so much larger gain.

A 25m dish, and the work of amateurs is a really nice story!

A plot showing frequency offset on x-axis and power in dB on the y-axis. The data shows a radio signal with a lot of noise as the main component, and a single spike rising to 61 dB. This is the signal of the Voyager 1 spacecraft.

The 25m Dwingeloo radio telescope (owned by ASTRON) has been operating since '50s. Recently, it has been used more by amateurs and pro-am radio astronomers.

Excitingly, they picked up the Voyager 1 signal.

Voyager 1 is ~25 billion km away! (~4 x Pluto distance)

My favorite nebula! 😍

Sadly it’s unlikely I’ll be able to ever see it with my own eyes 😭

Incredible! I’m actually in the Southern Hemisphere (Sydney) for the first time in my life but I think I’ll have little chance to do any observing given all the clouds 😭

This is HUGE!

A few years ago I made some International Space Station HDEV-style renders from Mars Color Imager (MARCI) data, a camera which images most of the Martian surface daily. This video captures the 2018 global dust storm just as it was rolling into Oppy's field site in Meridiani Planum (at ~21 minutes)

Hi Blueskyers. I run the organization @protectdemocracy.org which aims to do just that.

Over the past decade we’ve won countless cases to protect voters and truth, helped pass legislation, and unfortunately predicted much of what’s happened.

Follow and repost so we can keep doing that here.

Sarah McBride: "It is an attempt to distract ... Every single time we hear them say the word 'trans,' look what they're doing with their right hand. Look at what they're doing to pick the pocket of American workers, to fleece seniors by privatizing Social Security and Medicare."

Governor Gavin Newsom is one of the few Democrats who has spoken up after the elections, in this continued fight for Democracy. For those who want to volunteer:

For the first time in my life, I’m on strike! ✊

Last weekend, Earth’s most famous technosignature — known as the Arecibo message — celebrated its 50th birthday.

In a story for SciAm, I had the chance to explore the transmission's significance, both then and now.

I couldn't have done it on my own, so here's a bit of how it came to be...🧵

Done! And I reported and blocked a couple more 🫠

Don’t ever think your vote doesn’t count in a blue state! 👇🏻

What I love about this Officially Verified Bluesky Press Lists is it includes a real mix of people at major legacy media outlets, independent organizations, and freelancers.

We can promote a diverse media when billionaires don't control what you see.

Let's keep it growing!

How Attacks Against Obamacare Turned Into Tools to Protect Abortion Access Conservatives amended state constitutions to affirm broad rights for people to choose their health care. Now abortion rights proponents are taking them at their word.

BIG NEWS: A Wyoming judge just struck down WY's abortion bans.

And get this: The judge invoked a constitutional amendment codifying a right to make health care decisions... that was passed in 2012 by conservatives who thought it'd screw Obamacare! Just backfired.

We explained this lawsuit here:

We are constantly adding vetted activists to our @demcastusa.bsky.social starter packs.

We had to start a second one because we filled up the first!

Please be sure you’re following these folks!

Pass it on.

Clockwise: Overhead views of the Main Garden & side garage raised beds for veggies in early summer; Pollinator Garden & other veggie raised bed areas in late Spring which are encircled by a stepping stone path slowly being filled in with low pollinator plants; overhead views of the entire garden area opposite the Main Bed; Rain Garden in early late spring where we once had mud and dead grass.

Slowly & sorely (🤣), I have created a #nature oasis for #birds, #pollinators, & more in middle of city 1/2 mile from closest green corridor. We have added #NativePlants & non-invasive friends to bloom #FebruaryToFrost, truly productive #KitchenGarden, & solved all of our water issues. #gardening 🌱

Here’s a great Starter Pack from @aaronblack.bsky.social!

Pass it on.

All restaurants need to do this.

New starter pack: I created this one for people interested in research on #science #communication and public #engagement with science. Feel free to follow them, share the list, and suggest additions! #scicomm
