Some small asteroids can abruptly explode

Some asteroids are more dangerous than others, according to a report published in Nature Astronomy by an international team of researchers, led by astrophysicist Auriane Egal of the Montreal Planetarium in Canada. The team had presented their findings of an investigation into the impact of small asteroid 2023 CX1 over France in February 2023. This new paper revealed that small asteroids can explode on atmospheric entry.

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.

Single-shot laser technique captures plasma evolution at 100 billion frames per second

Plasma, ionized gas and the fourth state of matter, makes up over 99% of the ordinary matter in the universe. Understanding its properties is critical for developing fusion energy sources, modeling astrophysical objects like stars and improving manufacturing techniques for semiconductors in modern cell phones.

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 mineral nodules and multicolored, leopard print-like splotches.

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 developing systems that will enable In-Situ Resource Utilization (ISRU) in extraterrestrial environments, which is essential for making space sustainable. This includes their Blue Alchemist ISRU system, which recently completed its Critical Design Review (CDR).

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.
