They got here from outer house: Ohioans showcase their meteorites

Space is soiled. Filthy. It’s suffering from asteroids, and rocks, and mud. Some of that materials falls to the earth. When it enters the environment, we name it a meteor. If it lands, it is a meteorite.

John Ventre often retains his meteorites locked away in a security deposit field. This weekend, he’ll put them on show for different collectors and the general public.

He holds a silvery slice of jagged house rock in opposition to the sunshine. It’s about 6 by 4 inches, and an eighth of an inch deep.

“And what’s neat about this particular one is … you can see pieces of olivene, which are translucent green gems.”

Ventre, who’s in his 90s, first began gathering when he was in faculty and acquired some meteorites at a museum reward store.

He has donated some items, together with a few 25 pounders, to the Cincinnati Observatory, however nonetheless has greater than 100 in his assortment

“The smallest one, gee I don’t know, would be about the size of a fingernail, I guess,” he says.

Some collectors, like Dusty Segretto of Louisville, have samples so much smaller than that.

He arrange a microscope inside a espresso store and confirmed some to the shop’s artwork curator, Beth Akins. His micrometeorite images have been featured there for the month of September.

Segretto had even scooped up dust and particles from the roof of the store.

“Not much to look at from here, but this is eight micrometeorites. And you can look at them under the microscope too,” he says.

“Oh! They’re beautiful!” says Akins.

Another slide is crowded with grains of sand, a few thread-like buildings, and one thing that appears like a potato chip.

Segretto says he spends about 16 hours every week looking out.

“This is really a signal to noise game. Where you go up to a nice flat roof. Anything up there is either from wind or from space. You gather up some of the material and you separate it with a magnet.”

He says that the magnet will pull out something with iron in it. And from there, it is like panning for gold.

“Imagine you had a clear bucket with clear water and sand in it and you swish it all around. The sand is going to fall real quickly to the bottom, right? It doesn’t take very long,” he says. “But anything that’s not heavy and dense is going to float. And so you keep pouring and pouring until that heavy stuff remains.”

He appears to be like by means of what’s left. At a look, it may be tough to inform a meteorite from a standard earth rock. But, beneath that microscope, house dust would not appear to be something from earth.

“They really stand out. They look different. They look beautiful. They have a structure to them. They have forms and colors that you don’t see in terrestrial dirt because they went through a process via its entry to the earth that terrestrial material never really goes through.”

Segretto says he loves in search of micrometeorites, as a result of there’s all the time the prospect he’ll discover one thing nobody has ever seen earlier than.

“Even though they start from the same materials, they end up very different looking and have different personalities based on what happened to them on the planet. I feel like that’s kind of like us. We all start from the same stuff but we have our own trajectories and it makes us unique. It makes us interesting and cool.”

Segretto says you are by no means greater than a meter away from a micrometeorite, and you may by no means know what’s there till you are taking the time to search for it.

Cincinnati Observatory Astronomer Wes Ryle says a number of meteorite collectors will probably be available Saturday, displaying off what they’ve.

“It comes from a desire to let kids and families get a chance to actually put their hands on something space related,” he says. “As cool as it is to look at through a telescope at all these distant objects, the planets and the stars, it’s nice to have something tangible that you can hold on to that’s associated with space and the cosmos.”

Ryle says there will even be discussions and displays of “meteor-wrongs:” rocks that appear to be they’re from house however aren’t. The Meet-a-Meteorite occasion is Saturday night on the Cincinnati Observatory in Hyde Park.
