It has been suggested that lava tubes - underground tunnels carved out by molten rock - might be on Venus, and now we have direct evidence that this is the case ...

Scientists have presented the "first compelling evidence for the existence of lava tubes on Venus." And they're way bigger than we thought.

Lava tubes are familiar on Earth. They form when the surface of a lava flow hardens while molten rock continues to drain beneath, leaving behind a hollow conduit. On the Moon and Mars, weaker gravity ...

Massive lava-carved tunnels have been confirmed beneath the surface of Venus, providing the strongest evidence yet that the planet's volcanic past created underground networks unlike those ...

Mercury is tiny, barely bigger than the Moon. Its metallic core makes up 70% of the planet’s mass, vastly exceeding Earth’s 32% and Mars ’ 25%. It’s unlikely that the core actually formed like this.

New research presented at the Europlanet Science Congress 2025 in Helsinki suggests that Venus may be concealing some of the largest lava-carved tunnels ever discovered in the solar system. The ...

Venus is officially a lonely planet. After losing contact with the Akatsuki spacecraft last year, Japan’s space agency (JAXA) has officially ended operations of the lone mission left in our ...

Venus is similar in size to Earth, but it stays far hotter because its thick atmosphere traps heat, as shown by NASA’s facts. That extreme heat has not erased the planet’s scars, which include ...

On May 21, 2010, the Akatsuki orbiter ("Dawn" in Japanese) launched from the Tanegashima Space Center atop a H-IIA Launch Vehicle, establishing orbit around Venus in December 2015. In so doing, ...

New research shows hidden Venus asteroids could unleash city-sized impacts. Learn why they’re so hard to spot and how telescopes might find them.

Fifteen years after launch, JAXA has said goodbye to the spacecraft, our only working probe around Earth's "sister planet".

The ESA's Jupiter Icy Moons Explorer (JUICE), which launched in April 2023, has completed another successful flyby aimed at boosting its speed ahead of a Jupiter orbital insertion sometime in 2031.
