Glimpses of Coronal Rain

Nicole Sharp - July 10, 2025June 17, 2025

Despite its incredible heat, our sun‘s corona is so faint compared to the rest of the star that we can rarely make it out except during a total solar eclipse. Keep reading

Composite image with CFD of a space capsule entering the atmosphere. The capsule is colored in reds, oranges, and yellows, showing surface temperature. Around it, in grayscale, is the vorticity of the flow field. Phenomena

Bow Shock Instability

Nicole Sharp - July 9, 2025June 17, 2025

There are few flows more violent than planetary re-entry. Crossing a shock wave is always violent; it forces a sudden jump in density, temperature, and pressure. But at re-entry speeds Keep reading

Prototypes of fog collectors, with the hybrid fog harp shown on the right. Research

Building a Better Fog Harp

Nicole Sharp - July 8, 2025June 17, 2025

On arid coastlines, fog rolling in can serve as an important water source. Today’s fog collectors often use tight mesh nets. The narrow holes help catch tiny water particles, but Keep reading

Sediment stirred up by storms lightens waters off the coast of Aotearoa New Zealand. Phenomena

South Island Sediments

Nicole Sharp - July 7, 2025June 17, 2025

In April and May late autumn storms ripped through Aotearoa New Zealand. This image shows the central portion of South Island, where coastal waters are unusually bright thanks to suspended Keep reading

Flying Foxes

Nicole Sharp - July 4, 2025June 16, 2025

A sweltering day in India brought out the local giant fruit bats (also called Indian flying foxes) to keep cool in the river. Normally nocturnal, they made a rare daytime Keep reading

Martian Streaks Are Dry

Nicole Sharp - July 3, 2025June 16, 2025

Dark lines appearing on Martian slopes have triggered theories of flowing water or brine on the planet’s surface. But a new study suggests that these features are, instead, dry. To Keep reading

Listening for Pollinators

Nicole Sharp - July 2, 2025June 16, 2025

Can plants recognize the sound of their pollinators? That’s the question behind this recently presented acoustic research. As bees and other pollinators hover, land, and take-off, their bodies buzz in Keep reading

Rolling Down Soft Surfaces

Nicole Sharp - July 1, 2025June 16, 2025

Place a rigid ball on a hard vertical surface, and it will free fall. Stick a liquid drop there, and it will slide down. But researchers discovered that with a Keep reading

Solar Orbiter captured this first-ever view of the Sun's southern pole. Phenomena

Seeing the Sun’s South Pole For the First Time

Nicole Sharp - June 30, 2025June 16, 2025

The ESA-led Solar Orbiter recently used a Venus flyby to lift itself out of the ecliptic — the equatorial plane of the Sun where Earth sits. This maneuver offers us Keep reading

“Now I See – The Collection Vol. 2”

Nicole Sharp - June 27, 2025June 9, 2025

In the next video of his current collection, Roman De Giuli takes us flying over liquid landscapes that look like our Earth in miniature. Many of them have the feeling Keep reading
