NASA’s tally of planets outside our solar system reaches 6,000

The official number of exoplanets—planets outside our solar system—tracked by NASA has reached 6,000. Confirmed planets are added to the count on a rolling basis by scientists from around the world, so no single planet is considered the 6,000th entry. The number is monitored by NASA’s Exoplanet Science Institute (NExScI), based at Caltech’s IPAC in […]

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 […]

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

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 […]
