rottingleaf, w Elon Musk destroys astronomy

Can we just do things the conservative way and lay more wire?

And where that doesn’t help, use packet radio links?

And where that doesn’t help, use mesh networks?

Why do they have to do it all the ugly and pretentious way?

lemonmelon, w Size Comparison: Pluto and Australia

What is this, a planet for ants?!

dodgy_bagel,

It’s a close-up shot; the planet in this photo is actually much bigger than Australia.

Klear,

Then again it could be super close and the size of a potato.

dodgy_bagel,

Potatoes aren’t usually blue

Klear,

They are if they are moving towards you really fast!

dodgy_bagel,

Imagine hitting that fast ball

mindbleach,

Extremely venomous ants.

lvxferre, w A New Deep Learning Algorithm Can Find Earth 2.0

This is what machine learning is useful for. Not to try to convince you that oranges are active and potatoes are passive, or to give you a thumbs up with 7~8 fingers. But to detect patterns and allow automation of repetitive tasks.

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

I’m not even bothering opening the article, the rant is for the channel or whatever the room is called in Lemmy

It’s a good time to blacklist this news source.

This hypothetical planet was cooler when it was called “Planet X.”

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

There are certain aspects of it that look more complicated than they are because you are seeing it as a representation on a flat map. It makes a lot more sense when you see it on a globe with all the pieces moving in 3d space.

It is complicated because there are tilts to the earths rotation and a tilt to the moon’s orbit, but people thousands of years ago figured it out, so it’s solvable.

Why you gotta be so mean to my itty bitty moon brothers and sisters?

elmicha,

Does Earth also have such small orbiting rocks that are a few kilometers wide?

Bumblefumble,

No, we only have one moon. I think the gravity of the moon is too large for other moons to be in a stable orbit around Earth.

tunetardis, w For your processing pleasure: The sharpest pictures of Jupiter's volcanic moon Io in a generation

It’s impressive how much detail Juno was able to capture even on the night side. What I love about Io is how it’s instantly recognizable. Nothing even remotely resembles it in the solar system.

derphurr, w Discovery of second ultra-large structure in distant space further challenges our understanding of the universe

It’s not a “new” discovery or even the “second”. I suggest they read the 2015 paper they are almost copying from.

2015 dx.doi.org/10.1093/mnras/stv1421

Evidence suggests that this feature is the projection of a shell on to the plane of the sky. Voids and string-like formations are common outcomes of large-scale structure. However, these structures have maximum sizes of 150 Mpc, which are an order of magnitude smaller than the observed GRB ring diameter. Evidence in support of the shell interpretation requires that temporal information of the transient GRBs be included in the analysis. This ring-shaped feature is large enough to contradict the CP. The physical mechanism responsible for causing it is unknown.

Weird reporting like this is “new” GRB ring out of Swift and Sloan SDSS data.

Sloan Great Wall, which is around 1.5 billion light-years in length

South Pole Wall, which stretches 1.4 billion light-years across.

Hercules-Corona Borealis Great Wall, which is about 10 billion light-years wide

2015 en.m.wikipedia.org/wiki/Giant_GRB_Ring

It is approximately 9.1 billion light years from Earth and about 5.6 billion light years across

New objects:

Big Ring in the Sky is 9.2 billion light-years from Earth. It has a diameter of about 1.3 billion light-years

Giant Arc in the Sky which is 3.3 billion light-years across,

thefluffiest, w Nasa unveils quiet supersonic aircraft in effort to revive commercial flights

And exactly how much CO2 emissions does this thing generate?

joostjakob,

It makes me so mad we don’t just tell the flight industry that by date X no planes that use traditional fuel can be produced, and by date Y that they won’t be allowed to fly. Doesn’t even need to a global agreement, if the European market is closed, than that could be motivation enough. And it would focus innovation on efficiency instead of frivolous stiff like this.
