Scientists say if Venus ever had a moon like ours, it was doomed

MASHABLE - Venus' sluggish spin may be the key to why it doesn't have a moon — anymore, at least, new research says. The study, led by University of California, Riverside astrophysicist Stephen Kane, appears in The Astrophysical Journal. Kane's team built computer simulations of how gravity ties a planet to a moon in space...

Did Venus 'swallow' its own moon?

BBC - Scientists have come up with a surprising new theory about one of our neighbouring planets - and it involves a missing moon. They think Venus may once have had one, but that it slowly moved closer to the planet, before eventually crashing into it. The idea could help explain why Venus doesn't have...

Scientists can predict where the next devastating earthquake will hit

POPULAR MECHANICS - On July 30, 2025, at 11:24 a.m. local time, a massive magnitude 8.8 megathrust earthquake rattled the eastern coast of Russia’s Kamchatka Peninsula. It was the largest seismic event since the Tōhoku earthquake in 2011, although thankfully it was much less deadly. The massive quake happened along the Kuril–Kamchatka subduction zone—a fault...

Astrophysics study suggests Venus may have swallowed its moon

REUTERS - A California-based astrophysicist presented a new theory on Monday to explain why Venus, the ​planet most like Earth in size, mass and structure, lacks its own moon. Call it a case of celestial cannibalism. The ‌extremely slow speed at which Venus rotates on its axis would have doomed any natural satellite that may...

Why is Venus hotter than Mercury, when Mercury is closer to the Sun?

LIVE SCIENCE - Given that it's the closest planet to the sun, Mercury seems like it should be the hottest planet in our solar system. However, at a blistering 900 degrees Fahrenheit (480 degrees Celsius), Venus tops Mercury's 800 F (430 C) highest surface temperature, despite being an average of 31 million miles (50 million...

Scientists are getting better at predicting where massive earthquakes will strike

EARTH.COM - Nobody can tell you exactly when an earthquake will hit. But a team of scientists has gotten remarkably good at answering a different question: where. Their new method, developed at the University of California, Riverside (UCR), flags the specific stretches of major earthquake faults where stress has been quietly piling up for years...

Scientists say they can now pinpoint where big quakes might hit

GIZMODO - Earthquakes may strike without warning, but the ground beneath us is rarely completely still. Current systems can measure these tiny movements with remarkable precision, but until now, they have been used mainly to understand how faults behave rather than to predict where an earthquake might strike. Now, a new approach is challenging that...

Scientists say they can now predict where an earthquake will strike next

KTLA 5 LOS ANGELES - Scientists at the University of California-Riverside have developed a way to identify where the biggest earthquakes are likely to occur. UC Riverside researchers say that their methodology identifies where stress has been building along major faults, so scientists can determine where a rupture will take place. It does not predict...

Venus might have once had a moon. But the hellish planet could have destroyed it

ZME SCIENCE - Venus has no moon today. But it may not always have been alone. A new study suggests that if a giant impact gave early Venus a substantial moon, tidal forces could eventually have reversed the satellite’s path and dragged it back toward the planet. Venus would then have torn the moon apart...

Venus highlights a big problem with how we measure alien planets

ZME SCIENCE - Discovering Venus-like conditions beyond our Solar System could reveal why some rocky worlds remain havens for life while others become scorching greenhouse infernos. Before solving that mystery, however, astronomers must determine how quickly those distant planets are truly spinning. Slower rotations can cause hellish conditions astronomers see on Venus, but new research...
