- Planetary Science
Giant polygon rock patterns may be buried deep below Mars’ surface
A Chinese rover used radar to reveal long-buried terrain that might hint that Mars’ equator was once much colder and wetter.
- Earth
Before ancient Egyptians, nature sculpted sphinxes. Here’s how
Steady winds can carve landforms called yardangs — thought to have inspired the Great Sphinx of Gaza — from featureless blobs, a new study suggests.
- Physics
Physicists get a first glimpse of the elusive isotope nitrogen-9
With seven protons and two neutrons, the lopsided atomic nucleus of nitrogen-9 pushes the limits of what can even be considered a nucleus.
- Astronomy
A rare glimpse at a relatively nearby supernova offers clues to how stars die
Thanks to its home in the Pinwheel galaxy, a favorite of amateur astronomers, researchers have monitored SN 2023ixf since shortly after it exploded.
- Planetary Science
In a first, astronomers spot the afterglow of an exoplanet collision
A surge of infrared light from a remote star might have been a glow cast by the vaporized leftovers of an impact between Neptune-sized worlds.
- Astronomy
This ‘polar ring’ galaxy looks like an eye. Others might be hiding in plain sight
New images of two galaxies reveal what look like rarely seen rings of hydrogen gas nearly perpendicular to the galaxies’ starry disks.
- Space
Clara Sousa-Silva seeks molecular signatures of life in alien atmospheres
Quantum astrochemist Clara Sousa-Silva studies how molecules in space interact with light, offering clues to what distant objects are made of.
- Particle Physics
Scientists finally detected oxygen-28. Its instability surprised them
The elusive isotope was predicted to be very stable, thanks to “magic” numbers of neutrons and protons. It fell apart almost immediately.
- Animals
Wild male palm cockatoos rock out with custom drumsticks
Along with flashy dances and distinctive drumbeats, these birds craft their own signature drumsticks to win over mates.
- Astronomy
Spiral galaxies might have been lentil-shaped before becoming starry whirls
By using black holes to track how galaxies merge and grow, an astronomer has proposed an update to the prevailing story of how galaxy shapes evolve.
- Planetary Science
A rain of electrons causes Mercury’s X-ray auroras
The first direct measurement of electrons raining down on Mercury suggests this particle precipitation causes most auroras in the solar system.
- Paleontology
‘Thunder beast’ fossils show how some mammals might have gotten big
Rhinolike mammals called brontotheres repeatedly evolved into bigger and smaller species, a fossil analysis shows. The bigger ones won out over time.
