My cup overflows with anger toward these lying, deceiving, murderous, oil and gas companies. So this morning, I did something I've never done before in hopes the people coming home from their long weekends in Tofino and Ucluelet get the message.

Please Boost.

The bald eagle could have easily gone extinct. But we did all sorts of "woke" things protecting it legally, ran conservation and study programs, banned DDT (that was good for other reasons too) and in 2007 they were removed from the endangered species list.

Likewise pine forests could be dead from acid rain.

The ozone could have a huge hole.

We CAN take care of nature when we want to. And the successes have been worth it.

I feel like we forget this, you know?

I submitted a comment to the FCC regarding my disapproval of direct-to-cell satellites. Please consider adding your voice to help preserve the night sky and the sensitive environments of Earth’s upper atmosphere and low-Earth orbit. You can find specific details on what you can do at https://www.kesslerrebellion.com/take-action. The FCC is open to taking comments from individuals around the world, not just in the USA.

Derelict satellites pass within 1,000 kilometers of each other 1,000 times a year, and any collision would instantly double the amount of space debris. A space rush is filling up orbit with unregulated satellites, mostly from private companies, and we need better protections https://www.scientificamerican.com/article/there-is-too-much-trash-in-space/

So, over in the astronomy world there is some consternation about a tweet from eminent satellite tracker Jonathan McDowell.

Apparently "Starlink Precipitation" is now a thing. And yes, you got that right, Starlink precipitation is pieces of Elon Musk's fucking internet satellites raining down from space.

Very wonderful (and rightly depressing) public presentation by @sundogplanets this evening in Toronto. Thank you for your advocacy and for coming to this urban centre to share and inspire us. Please consider joining your voice and working together to secure a cleaner environment, safer future, and improved access to dark skies by going to https://www.kesslerrebellion.com/take-action.

Incoming! A severe G4 Geomagnetic Storm is expected to arrive around 02:00 UTC Friday night / Saturday morning.

At least 5 Coronal Mass Ejections took place over the past 24 hours, directed towards Earth. These originated from a large and magnetically complex sunspot cluster (NOAA region 3664).

There is potential for disruption of communications, the electric power grid, navigation, radio and satellite operations.

And bright auroras as far south as Alabama!

Starlink just launched another batch of satellites during a G4 Geomag Watch?? Unbelievable. They have no idea what they are doing. Waiting for the NOAA Severe Storm press release with angst.

There are 2 things to know about US agriculture.

  1. It’s very hard to make a living as a new farmer.

  2. About half our farmland is owned by wealthy families, investment funds, & others who buy it up as an asset- but don’t farm themselves.

There IS a fix to both problems!

sarahtaber,
@sarahtaber@mastodon.online avatar

And here’s the thing: more of the US’s farmland is farmed by tenants now (40%) than in a previous peak during Jim Crow (28% in 1920).

We sure do love to talk about how agriculture's changed over the last century. But somehow, we missed that very significant detail!

Managed to catch a just-shy-of-X1-class flare a few hours ago when I put my scope out on the deck.

The complex chaos of magnetic fields — that is much, much larger than the size of Earth — designated as Region 3664 and Region 3668 (center right sunspot smudge) has been spawning a great number of flares recently, flinging an truly stupendous amount of energy and relativistic particles out into the solar system.

malcircuit,
@malcircuit@thingy.social avatar

So some of that stupendous amount of energy and particles that Region 3664 kicked off earlier in the week is projected to arrive here on Friday night, causing a G2 geomagnetic storm.

If you live up dare in da north and it's clear out where you are (and you have a sufficiently dark sky), I highly suggest stepping outside and looking for some possible aurora in the sky. The viewline dips as far south as Chicago.

@sundogplanets Bit late to the thread due to too much admin stuff this week.

Consensus on this revolves around evolution and animal breeding for specific characteristics. An interesting article can be found from a public radio link:

Columbia's website cites the 1968 violence it deployed against students and triumphantly declares, "Columbia is a far different place today than it was in the spring of 1968."

Columbia's actions tonight, 56 years to the day, to once again deploy police against students protesting war, prove otherwise.

Wooooaaahhhh!

The new JWST image of a small bit of the Horsehead Nebula is INCREDIBLE.

To give you a sense of scale here, here’s an image of the nebula from my backyard. That small white box … that’s the JWST field of view! 🤯🤯🤯

Look at ALL those galaxies, all in that tiny white box.

JWST image credit:

Dodgy image with white boxes is my own.

At the bottom of the image a small portion of the Horsehead Nebula is seen close-in, as a curved wall of thick, smoky gas and dust. Above the nebula various distant stars and galaxies can be seen up to the top of the image. One star is very bright and large, with six long diffraction spikes that cross the image. The background fades from a dark red colour above the nebula to black.

Hey!

Are there any serious amateur astronomers out there? If so, I'd like to know what Saturn looked like to your eyes during Cassini's 13 yrs there. Did the rings look white? Pale pink? Beige? What about the various bands in the atmosphere? Did colors change w/ time?

When I asked this ? abt Jupiter prior to Cassini's Jupiter encounter, I received guidance frm those amateurs who specialized in color. Doing the same now.

Thx!

Last night I dreamed I was in a string quartet performance that was somehow a talk about satellite pollution. I wish I could figure out how to do this... playing angry music sounds way more fun than giving an angry lecture.
