(Please post your guesses and your name in the comments, and we’ll give the answer next week…)
Here at What on Earth, we’re constantly stumbling across interesting photos, videos, and audio clips from NASA’s exploration of our planet (be it from space, the field, or the lab.) Whether it’s a satellite montage captured from thousands of miles up, the roar of our B-200 research aircraft, or a microscopic view of a cloud droplet, there’s literally always something strange and wonderful passing across our desks.
To have a little fun (and spare all that fascinating stuff from the circular file), we’re going to post snippets of it every now and then, usually on Fridays. What we post will change, but the question to you all will always be the same: “What on Earth is that?”
Our only hints:
- Our picks will always be related to Earth science in one way or another, and…
- It will have some relation to what we do at NASA.
We’ll give you a week to post your guesses, and we’ll post the answer the following Friday.

Here are a few more details to impress your pals: Bits
of soot (a type of aerosol particle) tend to clump together into the chain-like structures visible above. Wildfires, diesel trucks, factories—anything that partially burns the carbon locked away in fossil fuels and organic materials can produce soot and release it into the air. Soot makes doctors nervous as it can cause health problems when it lodges in our lungs and works its way into our bloodstream. And climatologists are wary of the particles as well because they absorb the sun’s energy and hasten global warming and climate change by heating the atmosphere directly or coating the surface of glaciers. In recent years, black carbon is an active area of research in climate science, and it’s a target of study for a number of NASA’s Earth science projects, including the forthcoming Glory satellite.Image(left) from Peter Buseck, Arizona State University.

Or maybe its pollen?

bacteria molecules
Looks like a view of microscopic algae
Is it the microscopic view inside the Allen Hill’s meteorite?
Anaerobia bacteria from the depths of the Earth, a lifeform that exist in very extremes conditione. You study it because you suppose something similar might exist on another planet…

It is a SEM micrography of a Silicon agglomerate
is it an ant with some ant eggs?
It is a SEM Micropgraphy of a silicon agglomerate
an ant with ant eggs in micro gravity
fungus
Those newly discovered HIV antibodies?
Although I dunno. These look more mineral-like, so perhaps not.
1.-There are no discernible parts of a cell, so i would dare say it’s not organic
2.-It can’t be hair, cotton, or anything really tiny, since the shape doesn’t match.
3.- The shape of all the stuff resembles geometrical patterns, so i think it must be a crystal or a rock (most likely crystal)
4.-Since the image is in black an white, i can conly assume two things: either it was taken with a scanning electron microscope; or it was deliberately modified from it’s original colour.
Conclusion: lol?
My guesses: amplified crystal or mineral.
Wow, there he is – the Loch Ness monster is in the upper right hand corner. Looks kinda cute.
A virus, maybe one that lives in the ice.
I can’t work out exactly what it’s supposed to be, but it looks like a crystalline structure taken inside a scanning electron microscope.
it’s popcorn!
it looks like a secondary protein…
Flower pollen (and a bee’s leg in the top right corner)! Actually I have no idea.
eggs
It’s a new game… Obvious !…
x-rays of pop corns? lol
BP Oil spill
I think it is space dust as viewed through an electron microscope.
Tiberium crystals
A virus of some sort.
It’s a single cell from bacteria of space debris…..god…
Looks like a protein molecule
salt crystals of some kind grown in zerograv. Aluminum chloride?
Is it some kind of bacteria, found in the deep ocean? Or maybe in ice, like in Antarctica or in the North pole?
A blurred X-ray of the lighting pattern of earth, as seen from the space.
Thats lunar dust

It is a Leaf Cutter Ant tending or eating a fungus they cultivate.
It is a microscopic view of dust.
It looks like it is a molecular chain at an insane microscopic level.
I’m on a crash diet. It looks like my supper.

‘snow crystals’ per my wife, to me, it looks like crystals, but more permanent than ‘snow’
Its the Gas NASA puts into the Rockets
Carbon nanodiamonds found in Antarctic ice?
The first idea is eggs.
Salt crystals
Sugar crystals in a humid environment?
Maybe is a prokaryotic form of live , ……. What is it?
I am not sure at all but I am guessing it is a type of fungi or ice crystals.
Up and right is the ghost Casper! He is smelling some little potatoes!
Humm… it could be a forming mineral, like a pyrite, a melonite, or something like that
Its a DNA strand
I’m going with wild guess to say this is a hydrocarbon molecule like one would find doing aircraft fuel research.
fungus growth in zero gravity.
I looks like an electron microscope photo micrograph of sodium or calcium chloride, silicon dioxide, or some such crystal. It obviously is a three dimensional object since the object varies in focus in the depth of field.
I guessed sugar crystals before but the more I look at it, the more “uncrystalline” it looks.
Mabey its the powder used to polish telescope mirrors?
dust particles from Hayabusa.
I think is just nanometric particles of polution

I think ice crystal

No idea! May be some kind of crystal structure from Earth? I like this kind of challenges! Best regards
popcorn
I think, it’s a popcorn.

fumed silica or carbon
fumed colloidal silica or carbon black?
I guess it´s probably a picture taken from a electron microscope
It’s DNA or RNA.
Atomic number!

Thank you!
It is microscopic in nature and my guess is that it is Protein molecules……………..

It looks like coral but also could be so type of ice crystals
vista microscópica de musgo de manglares.
Some kind of alguae ?
Mauve some kind of alguae?
A protien. Maybe hemoglobin?
salt
The icon is in solid form, I strongly agree. Its my foremost hypothesis. When it has to do with solids, binoculars can’t really pass on through to its background neither it has to penetrate the rays of projection within.
Initially, I had arrays of clouds but I settle up to any solid of no specifics at all.
It must be a beads of stones piled up, something that is solid.

Particles of chalk like geographically known to have originated from chalk rock during early formation.
A methane-related carbonate
An electron-micrograph of a methane-related carbonate
I guess its white crystals, chalk like known as cretaceous formed during the early formation of chalk rocks in old days.
it is an nanometric image of some kind of pollen or simply pollution
Looks like it may be some type of larva laying eggs
Upon further reflection, I withdraw my former proposed answer (i.e., an electron-micrograph of a methane-related carbonate). I now propose that the image is an electron-micrograph of a methane hydrate.
It’s microscopic alge
I would venture a guess that they are particles collected by the Japanese Hayabusa asteroid probe.
salt crystals of some kind
Its like an bacteria
Aerosol particles as viewed by a scanning electron microscope.
hello sorry my english is not so good but i try to explane . when i see this picture fell/think like same as a one of millons univers Cell Arrays structural! or some like let me see again ! or dna? same structural but more luce (4 dimension structural) . everyday when i see some pictures ithink when the human understand the human body (System function) he now about the system of the univers. the human body have the same structural like the univers . but the human body is the littel copy version construction(4 dimension structural) plan ?.
Or are you to kid us and this are a air-to-space dust.
thanks and sorry for my English
IS IT AN ANT SPITTING FORMIC ACID OR FLUID FOR STICKING STUFF FOR APIARY NEST.(ASSUME IN SPACE STATION).
“very small rocks”?
Seems to be a hive of some sort; judging by its’ structural aspect of dependency, it looks like a single entity. That rules out a lot.
is it an ant eating salt, maybe while there is no gravity. just a guess.
