I'm a scientist studying fluid dynamics in the cores of rotating planets and stars. I mostly post pics of clouds and timelapses. All media by me. He/him.

A glass bottle on a table. But it's a special bottle because it ihas no inside or outside, it's one sided! its neck extends up and to a side and then goes back into the bottle joining its base.
Cirrus clouds directly above me. They are wispy white clouds against a blue sky. They are common these days of hot weather in Belgium.
Telescope image of a region of the solar disc, near the center. It shows two large sunspots, dark in their center and their edges have a spaghetti-like structure. The rest of the image show the solar surface completely covered with much smaller "granules" caused by vigorous convection at the surface. The granules are typically a few thousand km across.
Timelapse compressing 20 min of real time into 17 secs. The clip shows a region of the sky, where two kinds of clouds pass by. Going to the right are normal clouds perhaps up to a couple km high, and in the background going to the left in wavy motion, noctilucent clouds.
Towering storm clouds as the sun sets. You can see clearly the clouds' shadow outline projected onto other, more dispersed, clouds.
Screenshot of radar weather map showing a very intense thunderstorm extending over the whole Flanders in Belgium.
Picture of a large boulder, seemingly in mid air over a grassy field in the mountains. There's a person standing on the grass. There are clouds behind the boulder. In reality this is a picture of a rock on a lake, but upside down.
Timelapse video of the very thin Moon and Venus, very close to each other. The two drift from the top left corner to the bottom right. Some clouds pass by, also a plane.
Time-lapse of the moon, 5% illuminated, as it sets. It is only a sliver. Some clouds pass in front.
Wild thyme flowering, with a lego person for size comparison. The flowers are tiny, just a few mm across. They are pink.
Time-lapse movie of a distant thunderstorm, appearing as a cloud band. The sky above is clear and dark, except for some bright noctilucent clouds, which are much higher, and much more distant. There is also frequent lightning.
Pic of a frog in a pond, only her eyes above water. Some grass in the foreground.
Time-lapse of some clouds resembling "pouches" and hanging below bigger clouds. The pattern moves to the left evolving slowly.
Satellite image of the clouds around the Canary Islands. The wind makes a pattern of alternating clouds vortices as it goes over the mountains in the islands. That pattern is called a "Von Kármán vortex street"
Pic of the moon around Mare Vaporum. Towards the top left corner is the Apennines montes range, and towards the top left is Mare Serenitatis. In the Mare Vaporum plain itself there are a few rilles visible, particularly the Hyginus rille, near the center of the pic along with crater Manilius.
Telescope image of the moon, showing the mountains separating Mare Imbrium and Mare Serenitatis. Many craters can be seen, particularly crater Archimedes, towards the left, with 81 km in diameter and filled with lava.
Pic of yesterday's moon, nearly half-full. The terminator line appears almost straight.
Timelapse of the moon as it moves in the sky. New moon was only a couple of days ago, so it looks very thin. The Earthshine is strong, however and you can see the whole lunar disc. Venus is not too far, appearing as a bright dot as they both set.
Flemish landscape with clouds and an intense rain coming.
A plane flies through a thin layer of clouds, leaving a momentary clear air trace behind.
Partial image of the solar disc using a telescope and an infrared filter (IR 850 nm pass filter). The sun appears yellow and with a sort of texture (the solar granules). There are also some sunspots. In the center of the pic is the sunspot group denominated AR 4225.
Flowers of calendula, yellow with an orange tint.
In the foreground a laptop computer screen showing a telescope image of the sun. In the background is the telescope with its solar filter.
The nearly full moon, rising just above some trees.
screenshot of a text fragment that reads: "We are thinking about airlifting the rope-fixing team and their logistics to Camp 2 by helicopter, so they can open the route above that altitude for now," Ram Krishna Lamichhane, the department's director general, said.
Timelapse showing the moon, about 8% illuminated, as it sets behind some trees. The moon appears very close to the Pleiades, an open cluster of stars.
Slow motion video of some trees and clouds reflected on the surface of a lake. Some waves pass by, you can hear the slowed down singing of birds.
Short clip showing a calm water surface as raindrops start falling on it. Waves are produced as each raindrop hits the water.
Pic of plants with some flowers against a bright background. The plants appear as dark silhouettes. There are some other plants in the background too, but out of focus.
Greyscale pic of the moon, 19% illuminated. The dark side is visible thanks to the light reflected from Earth . The bright side is overexposed.
Picture of the setting sun just above some distant trees. There's a bit of haze, thick enough to show the sun as a sharp round disc. You can see even three sunspots, and the silhouette of a distant plane passing coincidentally in front of the solar disc.
Picture of the sun, without any filters, but through a heavy mist. It’s mostly gray except by a slightly brighter disc in the center. A few sunspots can be seen.
Greyscale picture of Jupiter through a backyard telescope. It's round, with alternating bright and dark bands. Also a dark spot, the Great Red Spot, a storm raging for at centuries. The bright dots near the planet are three of its moons.
Greyscale image of the surface of the moon showing two of the "Mare's" and a mountain range that separates them. A number of craters can be seen too.
Picture of a small area of the sun's surface with a backyard telescope. It shows dark areas surrounded by spaghetti-like structures. The rest of the surface shows granulation, which is caused by large scale (a few thousand kilometers) convection near the sun's surface.
Black and white picture of a small region of the moon, towards the lunar south pole. The surface is peppered with craters of many sizes.
Pic of the sky over some houses. The sky has some clouds but the clear areas have hues of green and pink-purple from the aurora.
Pic of the Orion constellation, with the stars out of focus to accentuate their color. Some stars are reddish, some are bluish. This pic is taken near Bogota, Colombia, which is close to the equator, explaining the constellation orientation very different from what northern hemisphere observers are used to.
A rocky cliff, the moon, and blue sky. The rocky profile resembles a human face, looking up to the moon and with its mouth open.
The sun is near setting but behind some clouds. Crepuscular rays come outwards from the cloud contrasting on the blue sky.
An antique car on a road next to the sea while the sun sets.
A female dancer in the foreground, with red and yellow skirt and top, her arms up in the air. In the background other dancers rejoice.
Pic of the sky after sunset. A bright patch of iridescent clouds appears over a dark band.
Aerial view of a field covered with dense fog. Wind turbines, very small as seen from a distance, create ripples and a wake-like pattern as the wind blows.
Meridional cross section of a resonant wave inside a gas giant planet with a convectively stable core. Colors indicate the velocity in the latitudinal direction. This wave has a dual character: a gravity (i.e. buoyancy) restored wave inside and an inertial wave outside (Coriolis restored, forming straight lines).
Picture of a star field, but the stars are way out of focus. They appear as round blobs and their individual color can be appreciated better that way. Some appear blueish, some other reddish, and others plain white.
