THE ATLANTIC - Earth’s fate rests on a coin flip. In 5 billion years, our sun will balloon into a red giant star. Whether Earth survives is an “open question,” Melinda Soares-Furtado, an astrophysicist at the University of Wisconsin at Madison, says. Sure, Earth could be swallowed by the sun and destroyed. But in some...
QUANTA MAGAZINE - Earth’s fate rests on a coin flip. In 5 billion years, our sun will balloon into a red giant star. Whether Earth survives is an “open question,” said Melinda Soares-Furtado, an astrophysicist at the University of Wisconsin, Madison. Sure, Earth could be swallowed by the sun and destroyed. But in some scenarios...
EOS - The folks next door can have a big impact on the livability of a neighborhood. If they’re loud, pushy, and obnoxious, they can force you out of even the most comfortable of homes. That truism applies to planets as well as people. The wrong kind of neighbor can kick an Earth-like planet out...
NATURE - Budget pressures at NASA, specifically arising from the increasing costs of several planetary science mission programmes, have rendered the Venus orbiter VERITAS as collateral damage. Currently on subsistence funding, mission scientists worry about the impact of ongoing delays on Venus exploration. Perpetually shrouded by dense, toxic clouds and sizzling with temperatures hot enough...
SPACE.COM - Like huge playground bullies, planets like Jupiter can be "agents of chaos" around other stars, a pair of new studies suggest. Gas giant planets that are the size of Jupiter or larger create havoc in young planetary systems, often shoving smaller, Earth-sized planets way out of their original, circular orbits, according to the...
FORBES - Massive planets like Jupiter—now at its brightest and best in the night sky—can prevent Earth-sized planets from becoming Earth-like by upsetting their orbits and destroying climates. In other star systems, gas giants can play a much more destructive role. As an example, the authors studied HD 141399, a star system also with four...
THE DEBRIEF - New stellar models predict that gas giant planets can act as ‘agents of chaos’ in their solar systems by wreaking havoc on the habitable zone orbits of Earthlike planets that may harbor alien lifeforms. Our solar system’s gas giants, Jupiter and Saturn, help protect the inner rocky planets, including Earth, from potentially...
EARTH.COM - In the cosmic game of planetary billiards, giant gas planets can act as colossal wrecking balls, effectively pushing their Earth-like counterparts out of the stable zones that might harbor life. Two recent papers dive into this concept further, investigating the roles of giant gas planets in two distinct star systems. What they reveal...
SCIENCE FRIDAY - Sixty-six million years ago when an asteroid slammed into what is now the Yucatan peninsula, it set off a period of near global darkness for almost two years. Scientists think a majority of land species went extinct during that time, but what was going on in the planet’s oceans? And how were...
IFL SCIENCE - One of the most extraordinary things about the impact of an asteroid that hit Earth 66 million years ago is not what died, but what survived. A new study found that one order of marine algae made it through by changing its source of energy, feeding on other life forms instead of...
