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...
CNET - Scientists have spotted something unexpected in the cloud decks of Venus, our nearest planetary neighbor. While no one is saying it's aliens just yet, some sort of alien microorganism is on the list of potential explanations for why a chemical that shouldn't be floating around above the planet has been observed there for...
UNIVERSE TODAY - In recent decades, over 4,000 extrasolar planets have been confirmed beyond our Solar System. With so many planets available for study, astronomers have learned a great deal about the types of planets that exist out there and what kind of conditions are prevalent. For instance, they have been able to get a...
CNN - Evidence of a worm-like creature about the size of a grain of rice has been uncovered in South Australia, and researchers believe it is the oldest ancestor on the family tree that includes humans and most animals. The creature lived 555 million years ago. "We thought these animals should have existed during this...
INVERSE - Timothy Lyons, a distinguished professor of biogeochemistry, discusses his new research to better understand the history of the atmosphere on Mars. Scientists have developed a new model to better understand whether Mars once hosted water — and maybe even life. The Martian surface is an inhospitable place: It is too cold for humans...
