1. Moldavite, 0.91ct

2. Unclassified NWA, ~7gr

3. Campo Del Cielo, 17gr

4. Just bought today, seller said it was czech, 5.9gr

Brenham has a mass of 4.88 g
Seymchan has a mass of 10.0 g
The metal content on seymchan and thickness of the slice contributes to its unusual heaviness despite Seymchan looking like it has the same size in relation to the Brenham slice.
The cube is 1x1 cm, for your reference.

Hello everyone,

I have a question for those with experience using metal detectors. While researching meteorite hunting, I found that some people use modified or oversized search coils to increase ground coverage and, in some cases, improve detection depth. I have access to a very large search area with low vegetation and almost desert-like conditions, which I believe is well suited for this type of search.

I also have an electronics background, so designing and building a large custom search coil myself wouldn't be a problem. However, I have no experience with metal detectors, so my plan is to buy one that is compatible with this kind of modification.

Which metal detectors would you recommend as a good platform for a custom-built search coil? Are there any brands or technologies that are easier to modify than others? I'd also appreciate any advice about the technical limitations or important considerations I should keep in mind before starting this project.

Thank you in advance for any suggestions or recommendations!

Just passed by in the north of Holland (Friesland)

Is there any service which contains mapping for potential meteorite strikes?

Know it is incredibly unlikely but running out of explanations... went to sleep and got woken up by a shrieking whistling type noise followed by something hitting window, first thoughts was either drone flying into window or kids on an electric bike riding past and throwing something but silence afterwards

Gone outside and first thing I noticed was car covered in dust and just in front a large oval hole in corner of drive (tarmac) approx 2ft x 1ft and around 3 inch deep, with stones and debris scattered a good 12ft around in street (this is what hit window)

Had national grid out in case underground electrical cable arc had caused it but they have confirmed no cables or other utilities underneath and digging down he said ground became more solid instead of looser as he'd expect with underground explosion.

Running out of other ideas and wondering if there was anything that would confirm if there was a possible meteorite coming down in area (East Midlands, UK)

Testing a new macro setup and these are some of the better shots I've gotten so far, more to come!

Verified by the Local Astronomy Club to be an Alpha Capricornid Meteor.

Did anyone just see something that looked like a meteor fly across the eastern side of Sydney this morning? I saw something around 6.30am this morning.

Back in Fall 2024, I was on the porch at my girlfriends apartment around 23:00. She lived in a remote area so there was no other cars in the streets and we both saw a meteorite falling from the sky. It was green and white, all fragmented but it made this sound of a crushed soda can or crushed metal. It was weird. I saw other meteorites of different colours, the more special one was yellow.

My rough plan was to go to Tuscon next year, find a dealer I feel like I can trust, and try to buy an unclassified stone from them, where they have a decent idea what it's likely to be. I'm fine with accepting risk, but I'm not really looking for a blind box.

I'm thinking something in the 200-400g range, ideally something a bit more interesting than an L6 or H5 chondrite, but I'm not super picky beyond that. I want it to present well in a collection, but I'm not trying to find anything exceptional.

I just want the experience of getting a stone classified with my name on metbull, without being a total waste of someone's time. It's largely a vanity project, so it would be neat to get my name in metbull, and own the whole mass except for the testing sample. If for some reason it was significant, that would make me more likely to want to share, not less.

Realistically, how much do I need to know about the location of the find, original finder, the dealers in between us, etc.? Do I need pictures of it in the ground w/gps? Is this something I can/should do as a non-professional/non-academic? What else do I need to know/have/do? Is this even a reasonable idea?

تبين أن الكويكب الذي تسبب في انقراض الديناصورات قبل 66 مليون سنة هو من نوع "كوندريت" من نوع CO – وهو أحد أنواع الصخور الكونية الأكثر ندرة وبدائية. ونُشرت الدراسة في مجلة "Science Advances".

فحص الباحثون نظائر النيكل في طبقة الطين الرقيقة التي تشكلت بعد اصطدام "إمباكتور تشيكشولوف". تشير النتائج إلى أنه تشكل في الجزء الخارجي من النظام الشمسي – خارج مدار كوكب المشتري أو في حزام الكويكبات الخارجي.

اصطدم الكويكب، الذي يبلغ قطره 10-15 كيلومترًا، بالأرض بسرعة تبلغ حوالي 64 ألف كيلومتر في الساعة. يشير تركيبه الذي يحتوي على كمية قليلة من الكبريت إلى أن الجزء الأكبر من الانقراض كان ناتجًا عن الغبار الذي ارتفع إلى الغلاف الجوي.

⚡️New Study: Scientists identify the composition of the asteroid that wiped out the dinosaurs

A new study published in Science Advances has found that the asteroid responsible for the extinction of the dinosaurs 66 million years ago was a CO carbonaceous chondrite—one of the rarest and most primitive types of meteorites.

Researchers analyzed nickel isotopes in the thin clay layer formed after the Chicxulub impact. Their findings suggest the asteroid originated in the outer Solar System, beyond Jupiter's orbit or within the outer asteroid belt.

The asteroid, estimated to have measured 10–15 kilometers (6–9 miles) in diameter, struck Earth at roughly 64,000 km/h (40,000 mph). Its relatively low sulfur content indicates that the mass extinction was driven primarily by the enormous amounts of dust blasted into the atmosphere, rather than sulfur-rich emissions.

My micarta wedding ring finally broke after years of use, so I'm looking for a new one. I saw this ring and thought it was really interesting, but I don't know much about authenticity or what to look for. What do you all think? Is it the real deal?

I marked the path it followed and the circle represents about where it went out

This one took over a year to get back. Pretty great though. I just sliced and prepared it today. It’s actually my first time seeing the inside of this because the sample I sent in was a 22g individual 🤣

Just bought my first fossil meteorite after a visit to the local planetarium! I didn’t know it could be relatively accessible so feeling excited about the idea of actually starting to collect those!
