Earth’s inner core: Nobody knows exactly what it’s made of, but now we’ve started to uncover the truth

The iron-rich core at the center of our planet has been a crucial part of Earth’s evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, it also influences plate tectonics which have continually reshaped the continents.

Lucy’s main belt target has its features named

When considering the unnamed major features of all the moons, asteroids, and comets in our solar system, there are still a lot of places out there that need proper names. That means the International Astronomical Union (IAU), the non-governmental body responsible for naming astronomical objects, has its work cut out for them.

Here are the tools Perseverance used to spot a potential sign of ancient life

NASA’s search for evidence of past life on Mars just produced an exciting update. On Sept. 10, 2025, a team of scientists published a paper detailing the Perseverance rover’s investigation of a distinctive rock outcrop called Bright Angel on the edge of Mars’ Jezero Crater. This outcrop is notable for its light-toned rocks with striking […]

From terraced hills to collapsed soufflés, scientists decode Venus’s mysterious surface

A research team led by geophysicists at UC San Diego’s Scripps Institution of Oceanography provides an explanation for features that characterize the surface of the solar system’s hottest planet.

Blue Alchemist is one step closer to creating sustainable infrastructure on the moon

Blue Origin is committed to making a permanent human presence in space a reality. To this end, they have developed the New Shepard and New Glenn rockets to send payloads to orbit, and aim to create super-heavy launch vehicles to reach the moon (New Armstrong and Blue Origin) and beyond. Another focus has been on […]

Mars’s chilly north polar vortex may create a seasonal ozone layer

A rare glimpse into the wintry conditions of the Mars north polar vortex has shown that temperatures inside the vortex are far colder than outside, and that the permanent darkness that winter brings to the Martian north pole facilitates a surge in ozone in the atmosphere.

New radio halo discovered with MeerKAT

Using the MeerKAT radio telescope, an international team of astronomers has performed observations of a galaxy cluster designated SPT-CLJ2337−5942. The observational campaign revealed the presence of an ultra-steep spectrum radio halo in this cluster. The finding is presented in a paper published Sept. 9 on the arXiv preprint server.
