Hestia, w First proof that “plunging regions” exist around black holes in space | University of Oxford
@Hestia@hexbear.net avatar

I mean, it’s pretty common sense that at some point inertia would be overpowered by the gravitational pull of the black hole. Pretty sure that’s what would happen if the moon got a little too close to us, too.

mouth_brood,

Of course there’s a point where something cannot escape the gravity. What this article states is that instead of continuing to orbit while perpetually getting closer to the singularity, once the plunging region is hit the light/matter/whatever drops in basically a straight line at the speed of light to the center.

Cokeser, w Mysterious Picture crowd of giant spiders on Mars, what's that?

TL;DR

Of course no spider aliens as the clickbait might insinuate.

These are cracks in the ice sheet caused by gases which when released to the surface bring dark material with them is spread on the ground in that manner.

Sunlight causes the carbon dioxide ice at the bottom of the layer to turn into gas, then build up and break the ice sheets on it. The gas explodes in the spring on Mars, dragging dark material to the surface over time and destroying the ice layer as thick as a meter."

shortwavesurfer, w Laser on NASA's Psyche asteroid probe beams data from 140 million miles away

Okay, that’s really cool and 25 megabits per second is actually very good compared to what they get back from other probes. At speeds like that, they could send back 4k pictures, which would be extremely high resolution for craft like this.

niktemadur, w Hundreds of black 'spiders' spotted in mysterious 'Inca City' on Mars in new satellite photos

Scientists baffled! (cue image of guys wearing glasses and white labcoats, clipboard in hand, ready to take notes at the drop of a pin)

“Uncanny” - said an unnamed, top researcher at the institute.
“Eerie” - said another.

ITT people on this thread need to listen to Jeff Wayne's War of the Worlds

LustyArgonianMana, w NASA officially greenlights $3.35 billion mission to Saturn’s moon Titan
@LustyArgonianMana@lemmy.world avatar

We want Healthcare.

EldritchFeminity,

Fund both. With 1% of the US military budget, NASA could afford to consider manned missions to Mars.

Sure, I am not opposed to science. Just can’t help pointing out the lack of Healthcare for all whenever I see these budgets for other programs. Kinda absurd for granny to be rationing her insulin when we have this kind of money available

wahming, w Caltech Researchers Find Evidence of a Real Ninth Planet

Petition to name it Xluto

sbv, w Caltech Researchers Find Evidence of a Real Ninth Planet

It’d be cool to see direct evidence of it.

Kichae, w [SciShow] The Solar System is Beige

Hey now, Venus has plenty of features! There’s that cloud, and that other cloud, and some clouds over there, and…

someguy3, w Car-size asteroid discovered 2 days ago flies 30 times closer to Earth than the moon

Is that big enough to not burn up in the atmosphere?

atzanteol,

This means it’s an asteroid with a weight-class that would have burned up in Earth’s atmosphere, if its orbit happened to intersect ours more directly.

dellish,

So… Asteroid that would have burned up in the atmosphere will miss us instead. I guess that’s good news?

atzanteol,

Livescience is 90% over-hyped nothing.

Shdwdrgn,

A quick search suggests that something as small as 5 meters can survive hitting the ground, however there are a number of calculations to consider including the speed it is traveling, the entry angle, and the material it is made of.

essteeyou, w Total Solar Eclipse - From 30 Years to 3 Minutes & 20 Seconds

“Hovering in the sky over Potato World” is up there in the top ways to start a sentence.

Glad you had a great experience!

Kichae,

I didn’t plan to view the eclipse over Potato World, but arriving at the hotel and discovering that it was next door did seem like a sign from the universe.

KittenBiscuits, w After 30 years, I'm finally going to see a total solar eclipse. Also, Potato World is a thing.

I am giddy-happy for you!

I’m glad you have someone with you to share in the event. It is going to be such a special day!

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?

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

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

maegul,
@maegul@lemmy.ml avatar

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!
