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...
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...
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...
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...
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...
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...
UNIVERSE TODAY - Mars holds a special place in the Solar System. It represents marginal habitability. This means it transitioned from warm and wet and potentially hospitable, to cold and dry and inhospitable. What can its transition tell us about exoplanet habitability? New research to be published in the Planetary Science Journal examines the question...
NEW SCIENTIST - Compared with Earth, Mars is tiny, yet it seems to have an outsized effect on our planet’s climate cycles. Similar small planets could affect the climates of worlds beyond our solar system, which we must begin to take into account when evaluating their potential habitability. Stephen Kane at the University of California...
THE WEEK - Small but mighty, the red planet — our celestial neighbor — has made Earth’s climate what it is today. Mars’ gravitational pull serves as a stabilizing force for our home’s orbit, tilt and position from the sun. Without it, life could potentially have been a lot different from what we know today...
ZME SCIENCE - Mars is about half Earth’s size and roughly a tenth its mass — not really the sort of planet you’d expect to leave fingerprints on Earth’s climate history. Yet a new set of simulations by an international group of researchers suggests the Red Planet helps shape some of the slow, repeating orbital...
