We finally know why Uranus is so cold

Uranus does in fact generate some heat.

Star Arms and Dark Beads in Saturn’s Upper Atmosphere

JWST reveals mysterious new features in Saturn’s atmosphere

The results came as a complete surprise.

Earth’s axis tilted nearly 80 centimeters east, study

Earth's pole has drifted toward 64.16°E at a speed of 4.36 cm/yr during 1993–2010.

Uranus

Uranus’s upper atmosphere has been cooling for decades. Now, scientists have shown why

The team predict Uranus’ upper atmosphere should continue to get colder or reverse the trend.

In this view from the Terra satellite, chunks of sea ice appear as white swirls off the coast of Greenland. As the ice thins and darkens, it reflects less sunlight than solid ice sheets, speeding up global heating.

Cooling power of sea ice is decreasing faster than its area

The Arctic has lost around a quarter of its cooling power since 1980.

Researchers find Earth and space share the same turbulence

Air turbulence in the Earth’s thermosphere is governed by the same principles as those in the troposphere.

No, you probably wouldn’t see bolts of lightning flashing from Venus’ clouds

Venus may be a (slightly) gentler place than some scientists give it credit for.

Giant solar eruption

For the first time, a solar eruption detected simultaneously on Earth, the Moon, and Mars

Emphasizing the need to prepare human exploration missions for the dangers of space radiation.

Kelvin-Helmholtz instabilities

Giant swirling waves identified at the edge of Jupiter’s magnetosphere

The waves are an important process for transferring energy and mass from the solar wind.

Auroral signatures

Scientists unveiled global observations of carbon dioxide aurora

Scientists unveiled global observations of aurora associated with carbon dioxide using satellite measurements.

microwave observations to spot the first polar cyclone on Uranus

First observation: Scientists discovered a cyclone on the north pole of Uranus

It’s a much more dynamic world than you might think.

Saturn

New images show the start of a new spoke season at Saturn

We will have longer dedicated time to study Saturn’s spokes this season, say scientists.

Modeling Mima's Interior

Saturn’s smallest moon could support an internal liquid ocean

Saturn’s smallest, innermost moon could generate the right amount of heat to support a liquid internal ocean.

Magnetic topology and electron flow direction

Scientists found evidence of magnetic reconnection between Ganymede and Jupiter

This gives us a very early tantalizing taste of the information we expect to learn from ESA’s JUICE mission.

Hunga Tonga-Hunga

Tonga eruption sparked massive phytoplankton bloom

After staying relatively inactive since 2014, the Hunga Tonga–Hunga Haʻapai volcano erupted on Jan. 2022. The eruption sent atmospheric shock waves, sonic booms, and...

Patchy proton aurora on Mars

Dynamic proton aurora events observed on Mars

The study presents first definitive evidence for spatially localized “patchy” proton aurora on Mars.

Marius Hills pit

Locations within pits on the Moon harbor comfortable temperatures

The pits or caves would also offer some protection from cosmic rays, solar radiation, and micrometeorites.

SATURN SHOWING AN AURORA

Scientists observed another mechanism driving Saturn’s Auroras

The study is based on observations made with the W. M. Keck Observatory on Maunakea, Hawaiʻi Island.
