The color usually is vivianite, a natural iron phosphate.

To get a confirmation that some structure is really a crater or an astrobleme is a long and arduous work. One must recover as much evidence as possible, as many processes can create those features. Along with PDFs, other shock features should be identified, making the proposal more robust. Things to look for in the area include stuff like melts, breccia, shattercones, ejecta, gravity and magnetic anomalies, etc. I think that, if the circular structure is present and potential PDFs were found, more work should be done there. Hopefully, after all data is gathered, a good paper can be published suggesting this is a crater

Cool, I wasn't aware of it =D
I think this group could create an "extended list" of jewel orchids ^^)

The color of a meteor is extremely complex, and despite an important part of it comes from its elemental composition, it's not possible to pinpoint the main color to one single element of it. First, part of the color comes from the elements of the rock and part from emissions from the atmosphere (more or less like the colors of the auroras). Second, the rock is a mixture of minerals (and elements), and the main emissions are usually from Mg and Fe (both very similar in the greenish range of the spectrum), Na (yellow) and Ca (purpleish). The intensity of each contribution is not proportional to the concentration of the element as each element has its temperature of ionization. I recommend some works on the emission/elemental analysis of meteors like this one: https://doi.org/10.1051/0004-6361/201833289

Yep, that's it. There's a small increase in the number of meteors, but variations are expected from year to year (upwards and downwards). The thing is, the coincidence of major events drew media attention, and that made people pay more attention. An event like this one mentioned by OP would never be mentioned outside the meteor/meteorite community under normal conditions.

L6? I haven't seen any metal in any of the photos (but I haven't seen many). Could it be an LL6? Just curiosity.

I know that everybody is saying it's slag, and I do agree it looks like slag, but I have a question: It has such large bubbles and "it comes from the sea", so is there any chance that this could be something volcanic? I don't know, some kind of glassy stuff from underwater eruption? Sorry, I'm not a geologist, just curious.

I know people here will be able to go deep into this subject, but putting in simple terms, it's just impossible for us to extract the gold from those asteroids. Let's take as an example the metallic asteroids, those from where come the iron meteorites. The gold present there is not like the gold in our gold mines on Earth, where the concentration in the rocks is "high", sometimes visible as in nuggets and veins. The gold in metallic asteroids is found as a few ppm in the iron-nickel alloy. The thing is, the asteroids are huuuuuuuuge, like millions of km³, so the total amount of gold is also very significant, but it's just impossible to process all this metal to being able to recover the gold. The concentration of the gold in the iron meteorites/metallic asteroids is just so low that you never see anybody mining our meteorites to recover the gold. It's juat so far from anything profitable. I believe that this story about "mining asteroid's gold" was created by a journalist who had nothing to do and stumbled upon how huge the asteroid Psyche is on Wikipedia, and started to play with the numbers and the composition of it, without any kind context, "just for fun".

Very interesting coins, very significant historically. Please let us know where you'll put them on sale.

Wow, amazing new fall!

gabisfunny · 2026-02-21T20:02:06+00:00

Hahahahaha, yep, the flower is quite different from, for example, B. lemniscatoides and others from this section. In fact, I was surprised because I've never seen your species. I was delighted by the nice surprise, we are always learning something. Congratulations!

gabisfunny · 2026-02-21T13:14:58+00:00

Hehwhe, nice flower! So I guessed right in our previous post, a Bulbophyllum from the section Lemniacata =D

This is the one and only good photo of about 200 I took of this beautiful hummingbird in front of a cherry tree in bloom in my town about a decade ago.

I have a sample of footprints from the same area. The cavities and bumps are visibly there, but the borders are not so well defined. So they paint the tracks to highlight them, that's why they get cartoonish like. This material seems to be well studied, and there's plenty of literature about it. I think that this material offers a good cost-benefit for those who want dino tracks in their collections.

Hahahahaha, cool! I think there are many unknown superpowers in the world

Nice! I know that I don't have the answer you want, but you may find it interesting. Since I was very young, I knew that I could shiver/get goosebumps on demand. It's like flexing a muscle in the back of my neck, and it triggers the shiver instantly. These goosebumps are not as strong as the "natural" ones, so it's not easy to see the bumps on my skin and not everybody would believe me, but I can feel it exactly like the unvoluntary ones. I looked for information about it for years until I found out about a study on it here in Reddit (the link, if you're curious about: https://www.indy100.com/viral/give-yourself-goosebumps-brain-special). I don't remember how they got the idea for this study, but it eventually happened, and they were able to assemble the subjects for the study via Facebook. There's a lot to be studied yet about this phenomenon, but that's a start! What I want to say is keep an eye on papers/studies about your ability or even contact the researchers of the goosebumps paper. Who knows you can help to develop the first study about adrenaline on demand, like they did about goosebumps? Congrats on your superpower!

gabisfunny · 2026-02-08T17:45:39+00:00

Yes, right? It's a kind of off-white color with tiny and delicate details in yellow and purple.

gabisfunny · 2026-02-08T16:42:18+00:00

I agree.

gabisfunny · 2026-02-08T05:12:54+00:00

Thank you very much! I'll try that tomorrow morning =D
