CbtB, w Fake Vs Counterfeit Eclipse Glasses. Did You Get Any?

I don’t know. I’ll have to check mine

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

No, it’s a mystical religious sign. Aren’t you paying attention?

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!

chalk46, w Stunning James Webb images show birth and death of massive stars

If it's not seen as much, that probably means the green material is heavier than iron. It's less common, but large enough stars can fuse even heavier elements. That's where all those elements on Earth came from in the first place.

then_three_more, w Northern lights predicted in US and UK on Monday night in wake of solar storms

It feels like this has happened a fair few times this year. Is the sun entering a period of heightened activity?

verity_kindle, w ESA's Euclid Telescope Has an Ice Problem

That is fascinating, I want to know, is there any way to prevent this during assembly? Even with extreme clean room protocols! Does it happen with other telescopes?! Down the rabbit hole, I must go.

MeanEYE, w A Nearby Star Is Expected to Go Nova This Year. Here's How You Can See It.
@MeanEYE@lemmy.world avatar

So, there’s nothing in universe that is longer than “soon”. This prediction of going nova this year, only means it already happened but you can’t see it yet. And since it’s going super nova, that means entire even will be boring anyway. You’ll see a white dot that will increase in intensity during this year and then fade away equally slowly.

For people wondering about dates, there are none. Just like Beetlejuice is expected to explode soon™, that actually means 3000-10000+ years of waiting. So don’t get your hopes up. Out lives are but a blink in universe. All you can do is be diligent and watch it constantly. Doesn’t mean you’ll see much either since at peak magnitude of 2.5 it will be dim enough that you’ll need telescope to see it.

XeroxCool,

Nova, not supernova. Novas happen multiple times. Supernova do not but it doesn’t say supernova. Soon, as in within the next 6 months since its following a cycle that happened about 80 and 160 years ago.

nulluser,

Visible with unaided eyes for several days (but still dimmer than about 120 stars in the sky), and with binoculars for about a week, according to NASA.

stockRot,

Did you read the article? Or do you just like talking?

ShittyBeatlesFCPres, w Saturn's largest moon most likely uninhabitable

Maybe for you but I’m built different.

givesomefucks, w There may be a 'dark mirror' universe within ours where atoms failed to form, new study suggests

I always thought of our universes as just a bubble, with dark matter all around us. It’s not the edge of the existence as much as the edge of our bubble.

We might not be the only bubble, but it’s impossible to interact or even observe them. Could be millions, could just be us. No way to every know.

Our bubble keeps expanding, until the edges aren’t dense enough to displace whatever’s out there. And we’ll either slowly fade and future civilizations will assume the universe has always shrunk. Because that’s all they’ve ever seen. Like if the human lifespan was a single minute, people would freak out everytime it approaches dawn or dusk. Not understanding that it’s a cycle.

It’s all about timescale.

LostXOR, w Solar eclipse on Mars! Perseverance rover sees Martian moon Phobos cross the sun in epic video

I remember another video of this from a while back, really cool!

Drunemeton, w JWST Imaged Two Apparent Alien Worlds Still Circling The Bodies of Their Dead Stars
@Drunemeton@lemmy.world avatar

I’m calling dibs on Neptune as my family’s home base in the future!

I know it’s several billion years in the future, but I called it.

moody, w Robot surgeon sent to the International Space Station to dissect simulated astronaut tissue

Is it Michael Reeves’ surgery bot?

MxM111, w Map reveals all the space junk we've already littered on Mars

It’s alien artifacts.

NGC1300 😮

GiantRobotTRex, w Airplane-size asteroid will have 'very close encounter' with Earth on Saturday — and you can watch it happen

Like a Cessna 172 size or an Airbus A380 size?
