Me too! Always wanted to get into, thinking it worthwhile to have a running solar system or celestial model on your own machine that you know how to operate etc. Just never really tried sadly!

marduk,

I used Stellarium today to see how the eclipse would look from my location, highly recommend it if you want to start playing

Oh yea I’ve used it and from memory it’s awesome as you say. I was more talking about getting into the technical details of running a model and calculating various things of personal interest.

Thanks for the recommendation though!

I’m pretty sure they just hold up a tennis ball and shine a flashlight on a globe, its not rocket surgery

dudinax,

I’ve heard from a government authority that the eclipse path is determined by how gay we are.

LemmyKnowsBest,

I like the way you think

JoMomma,

You’d be the first

So you want to be a computer algorithm?

LemmyKnowsBest,

Are you so deeply entrenched in modern technology that you cannot fathom that a human could comprehend and map future astronomical patterns?

Humans have been doing this since early records of humankind on earth. Loooooong before computers existed. Computers have only been around the last few decades.

dellish, w I want to be among those who deeply thoroughly understand & can accurately predict the path of future eclipses because this is amazing.

When I was a kid my parents bought me a book called “practical astronomy with your calculator” that went over all the workings and formulae for calculating eclipses, moon phases, locations of the planets and heaps more. If you want to get into it I highly recommend this book or something similar.

dellish,

BTW the book was by Peter Duffett-Smith if that helps.

Is London in the eclipse zone?

No—this is a good resource for finding the next one closest to you. www.timeanddate.com/eclipse/list.html

If you’re in Europe, northern Spain in 2026 is the next best opportunity.

Blaster_M, w Rainbow-like pattern found on planet outside solar system

We found Equestria? That would be a Harmony event going off. Someone on that planet got hit by the big friendship laser.

hydroptic, w Rainbow-like pattern found on planet outside solar system

I had no idea we could image exoplanets at a resolution high enough to be able to detect something like this, huh (and no I don’t mean the artist rendering)

Thcdenton, w Rainbow-like pattern found on planet outside solar system
AbouBenAdhem, (edited ) w Rainbow-like pattern found on planet outside solar system

I assume we can’t actually resolve spatial detail on the planet, so the effect must have been temporal. Would it have been something like a spike moving through the visible spectrum as the planet transits its star?

ivanafterall, w Rainbow-like pattern found on planet outside solar system

Yeah, look directly at the giant flesh space eyeball, smart.

givesomefucks, w Powerful X-class solar flare slams Earth, triggering radio blackout over the Pacific Ocean

The abundance of back-to-back solar events has led scientists to think the sun may have entered its explosive era of peak activity, known as solar maximum — which seems to be starting a year earlier than previous forecasts predicted. However, researchers will have to wait until the sun “calms down” to know for sure.

What we do know is that X-class flares are most common during solar maximum, which is part of the sun’s 11-year solar cycle. So far in 2024, seven X-class flares, including the latest one, have burst from the sun, which is already half the number that reached Earth in 2023, Live Science previously reported.

On a long enough timescale, we’re gonna be hit by a big one.

I remember like a decade ago they were saying it hits a developed area, it’ll blow out all the transformers, and on that scale no country could replace them all for a very long time.

Australis13,

I agree. There were articles and documentaries about 20 years ago that I remember featuring these sort of events. The continent affected would take 20-30 years to rebuild its electricity grid.

givesomefucks,

I’ll just never get over how “we” (science I guess) know that stuff like this isn’t a question of if, but when.

And we just don’t seem to get ready for it.

Like, Y2K we saw coming and everyone handled it in time. But if there’s no firm date on something, everyone with the power to do anything just ignores it.

As a society it just feels like we’re living paycheck to paycheck. Can’t worry about next year cuz rents due in two weeks shit.

It’s just not a good way to go about things.

Australis13,

In general, people are appallingly bad at weighing up long-term vs short-term stuff, both in terms of risks and benefits. It's even worse when, as you say, there's no definite deadline or it doesn't directly affect those who can do something about it.

Rolder,

“No electricity” definitely sounds like an “everyone” problem lol

@deafboy@lemmy.world avatar

If it’s an EVERYONE problem, clearly SOMBODY is doing something, so I can safely ignore it. /s

slazer2au,

What you didn’t see was the guy who made the problem in the 60s warn everyone about it from the 70s onward until his retirement in the 90s, then everyone say oh shit, he is right.

sploosh,
givesomefucks,

Yes, we get hit by them all the time…

What everyone else is talking about is a big one.

sploosh,

The Carrington event was a big one. It is estimated to have been an X40 flare. This article is about an X1.1 flare. Telegraph poles caught fire. The auroras were so bright people woke up and started making breakfast even though it was the middle of the night. They were visible as far south as central Mexico! If we got hit by a Carrington scale flare today we would be repairing the power grid for the next half century.

Rolder,

I believe it’s possible to avoid if the proper protocols are in place. Namely, the grid has to be turned off completely before the flare hits and then things will mostly be fine. Just wonder how well we can predict these events.

Australis13,

My understanding is that we actually don't have much of a warning (under an hour), since a CME has to reach the satellite at the Lagrange point between Earth and the Sun for us to know it's about to hit Earth. According to the article below, this includes power companies, but I remain skeptical that there's enough organisation in place to shut down the North American, European or Asian grids in 15 minutes.

Fucking enough “slams” in headlines!!!¹¹11one. /s

LimpRimble, w See photos of NASA's suitcase-sized rovers that will soon map the moon's surface
@LimpRimble@lemmy.ca avatar

Did I miss something? I couldn’t see where they said “will soon” and what that means.

Muscar,

“In early March, NASA announced that construction and testing of the three CADRE rovers was complete and the trio was ready for integration with Intuitive Machines’ Nova-C lander, which will deliver the mini explorers to the lunar surface later this year or early next year as part of the company’s third lunar lander mission, IM-3.”

At the end of the article. And here’s the website for the project with more info: www.jpl.nasa.gov/missions/cadre

Perfect, thanks.
