Uranus Emits More Than Thought

Since Voyager 2 visited Uranus in 1986, scientists have debated the odd ice giant's heat balance. The other giant planets of our solar system -- Jupiter, Saturn, and Neptune -- all emit much more heat than they absorb from the sun, indicating that they have strong internal heat sources. Voyager 2's measurements from Uranus indicated only weak heat emissions. (Image credit: NASA; research credit: X. Wang et al.; via Gizmodo) Read the full article

Veil Nebula

These glowing wisps are the visible remains of a star that went supernova about 7,000 years ago. Today the supernova remnant is known as the Veil Nebula and is visible only through telescopes.  (Image credit: A. Alharbi; via APOD) Read the full article

What Makes a Dune?

Wind and water can form sandy ripples in a matter of minutes. Most will be erased, but some can grow to meter-scale and beyond. What distinguishes these two fates?  (Image credit: M. Gheidarlou; research credit: C. Rambert et al.; via Eos) Read the full article

A Sandy Spine

Where sea and sand meet, Gaia's spine rises. Photographer Satheesh Nair captured this striking image in western Australia, where wind and wave action have dragged a dune into vertebrae-like cusps. (Image credit: S. Nair/IAPOTY; via Colossal) Read the full article

Seeding Clouds With Wildfire

Raging wildfires send plumes of smoke up into the atmosphere; that smoke is made up of tiny particles that can serve as seeds -- nucleation sites -- where water vapor can freeze and form clouds. To understand wildfire's effect on cloud growth, researchers sampled air from the troposphere (the atmosphere's lowest layer) both in and around wildfire smoke. (Image credit: K.

The Incredible Engineering of the Alhambra

Begun in 1238, Alhambra Palace in Grenada, Spain is a monument to Islamic architecture and clever engineering. Despite sitting far above the city, the Alhambra was fed by the river, diverted from upstream along a canal. (Video and image credit: Primal Space) Read the full article

Forming Vesicles on Titan

Scientists are still debating exactly what shifts nature from chemical and physical reactions to living cells. But vesicles -- small membrane-bound pockets of fluid carrying critical molecules -- are a commonly cited ingredient.  (Image credit: Titan - ESA/NASA/JPL/University of Arizona, illustration - C.

Cutting Out Canyons

Over the millennia, the Colorado River has carved some of the deepest and most dramatic canyons on our planet. This astronaut photo shows the river near its dam at Lake Powell.  (Image credit: NASA; via NASA Earth Observatory) Read the full article

Glacier Timelines

Over the past 150 years, Switzerland's glaciers have retreated up the alpine slopes, eaten away by warming temperatures induced by industrialization. But such changes can be difficult for people to visualize, so artist Fabian Oefner set out to make these changes more comprehensible. (Image credit: F.

Cloud Convection on Titan

Saturn's moon Titan is a fascinating mirror to our own planet. It's the only other planetary body with surface-level liquid lakes and seas, but instead of water, Titan's are made of frigid ethane and methane.  (Image credit: NASA/ESA/CSA/STScI; research credit: C.

Searching for the Seiche

On 16 September 2023, seismometers around the world began ringing, registering a signal that -- for 9 days -- wobbled back and forth every 92 seconds. A second, similar signal appeared a month later, lasting about a week.  (Image credit: S. Rysgaard; research credit: T. Monahan et al.; via Eos) Read the full article

See the Solar Wind

After a solar prominence erupts, strong solar winds flow outward from the sun, carrying energetic particles that can disrupt satellites and trigger auroras if they make their way toward us. (Video and image credit: ESA; research credit: P. Romano et al.; via Gizmodo) Read the full article

A Variety of Vortices

Winds parted around the Kuril Islands and left behind a string of vortices in this satellite image from April 2025. This pattern of alternating vortices is known as a von Karman vortex street.  (Image credit: M. Garrison; via NASA Earth Observatory) Read the full article
