The_Che_Banana, in Hubble finds strong evidence for intermediate-mass black hole in Omega Centauri

Intermediate-mass black holes (IMBHs) are a long-sought ‘missing link’ in black hole evolution. Only a few other IMBH candidates have been found to date. Most known black holes are either extremely massive, like the supermassive black holes that lie at the cores of large galaxies, or relatively lightweight, with a mass less than 100 times that of the Sun. Black holes are one of the most extreme environments humans are aware of, and so they are a testing ground for the laws of physics and our understanding of how the Universe works. If IMBHs exist, how common are they? Does a supermassive black hole grow from an IMBH? How do IMBHs themselves form? Are dense star clusters their favoured home?

No thanks. If I want to feel like I’m falling into a black hole all I have to do is read the news.

MindTraveller, in Astronomers discover two new Milky Way satellite galaxy candidates

Is dark matter just dwarf galaxies?

btaf45, in Astronomers discover two new Milky Way satellite galaxy candidates

If the distribution of those nine satellite galaxies across the entire Milky Way is similar to what was found in the footprint captured by the HSC-SSP, the research team calculates that there actually may be closer to 500 satellite galaxies

WTF? I was thinking there were around a dozen or so.

They solved one conundrum just to find another. Too few dwarfs then too many.

Now, is it really those colors is that just science stuff like all those dope pictures of nebulas?

Poor thing looks bruised. Who hit you?!

Olap, in 7 bizarre facts about the Solar System to stump any scientist

Clickbait headline quality article

btaf45,

Ethan Seigel never does "clickbait’ articles. He does 100% educational articles. I actually didn’t know more than half of these things. Who the hell knew that Earth does not have the most water in the solar system?

Olap,

It’s unusual for the author to write a headline fyi - and I do agree, full of great facts

It’s… beautiful.

Wait a goddamned fucking minutes that’s not cheese…!

cyberpunk007,

It’s cheese, gromit!

Wow. The level of writing failure in the headline is ALSO astronomical.

Steak,

They take pictures of other balls floating around they don’t teach English give em a break

funkless_eck,

he missed two letters.

Giftzwerg02,

ASTRONOMICAL!!!

Irrespective of the crater size, depth looks consistent. Does anyone know why that is?

Thorry84,

Multiple reasons:

Higher speed impacts penetrate deep, but also cause the rock to melt. This fills in deeper craters, limiting the max depth a crater can be. There are still very deep huge craters, but these look more like big depressions than craters, because of how big they are. They are also themselves covered with craters usually, making their size and shape harder to see.

Because the diameter of the moon is 3474km, a difference of several kilometers would only amount to a fraction of a percent. So even though one crater is for example 10km deeper than another, relative to the size of the moon this is practically nothing. When viewing pics like these where the whole moon is visible, this matters.

The moon is a very uniform gray color and lacks the indicators our brain use to gauge depth. This makes it very hard to guess how deep the different craters are. You can see some craters have more shadows where others don’t, but they are also different shapes and sizes and the lighting is different so it’s hard to see.

There is also probably some part of the speeds of incoming stuff being within a certain range and the moonrocks being relatively uniform in materials, so the range of craters than can exists is probably limited. But I’m not certain how big of an factor this is and what the range is.

And009,

I’m hoping there are missions to go in close, get a better look.

Thorry84,

There are plenty of missions right now. China has landed a rover on the moon this month. And multiple countries have satellites in orbit around the moon. Nasa has their Lunar Reconnaissance Orbiter which takes very high resolution images of the moon all the time and these are publiced on their website.

StaySquared,

The conspiracy about the moon is that under a thin layer of dust… it’s really all metal. /shrug

This image does a good job at making me realize we have explored basically nothing on the moon. SO much more to explore, yet we act like there’s no point trying to send more astronauts to the moon for decades. Please, increase NASA budget more.

nnullzz, in OP: "This is my most advance moon photograph EVER it consist of 81000 images and over 708GB of data." (see comments.)

With all the impacts the moon seems to take, is there any footage of a new crater being made? That would be super cool to see.

Feathercrown,

Here you go! First time seeing this footage myself!

youtu.be/000iTCoEE1s?si=mKO_1XCDVLYS-Yqk

I seem to recall a story about a large impact visible to Europe from Earth sometime around the renaissance as well, but I couldn’t find it.

nnullzz,

Oh wow! Thanks for sharing!

trslim, in OP: "This is my most advance moon photograph EVER it consist of 81000 images and over 708GB of data." (see comments.)

Quick! Someone tell Markiplier about this! (He hates the moon.)

Lexam, in OP: "This is my most advance moon photograph EVER it consist of 81000 images and over 708GB of data." (see comments.)

Came in to see the comments and my goodness they are lovely this evening!

Linking to Reddit kind of defeats the purpose of using Lemmy.

jol,

At least they posted the source

ArmokGoB,

Yes. However, we shouldn’t be sourcing content from Reddit at all.

jol,

I disagree. I welcome OC content like this.

mbfalzar,

I too welcome original content content

ArmokGoB,

It’s not OC. If it was, OP wouldn’t have had to link to Reddit to share it.
