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...

New study finds weakening Atlantic Ocean current could increase atmospheric rivers in California

ABC7 NEWS - A new study suggests a major ocean current in the Atlantic Ocean is slowing down, a shift researchers say could influence weather patterns around the world, including the intensity of storms affecting California. Researchers have been examining changes in the Atlantic Meridional Overturning Circulation, known as the AMOC, a system of ocean...

'It's absolutely exciting!': Astronomers discover an atmosphere around an Earth-like planet in the habitable zone for first time ever

LIVE SCIENCE - Astronomers have found the strongest evidence yet that a rocky planet beyond our solar system has managed to hold onto an atmosphere — a crucial ingredient for life as we know it. The discovery marks the first time scientists have detected an atmosphere surrounding a rocky planet orbiting in the habitable zone...

A major ocean current is on the verge of collapse. Scientists say the effects may reach California

SCIENCE ALERT - Earth's climate systems are inexorably and often unexpectedly interconnected. Dust from North Africa's Sahara Desert drifts thousands of miles to fuel food webs in the Amazon and the ocean's depths, while pollution-eating microbes hitch a ride through the atmosphere on gusts of wind or wisps of fog. Among the most influential planet-shaping...

Australian fossils reveal 550-million-year-old animal may be the first known right-hander

YAHOO NEWS - Fossils from South Australia are offering a surprising clue about the deep history of animal behavior. Spriggina floundersi, an ancient organism that lived about 550 million years ago, may represent the oldest known example of "right-handedness" in animals, suggesting a preference for turning right emerged long before hands, feet, or widespread complex...
