Weird young super-Jupiter challenges theories of planet formation

A newly discovered planet has the diameter of Jupiter but eight times its mass, giving it twice the density of Earth despite being composed mostly of gas. Not only have these characteristics of this “super Jupiter” left astronomers confused, but they could also challenge current theories about planet formation. The exoplanetwhich lies around 310 light-years …

Scientists make unprecedented detection on a planet 700 light-years away

Scientists make unprecedented detection on a planet 700 light-years away

The powerful Webb telescope doesn’t need to take pretty pictures to revolutionize our grasp of the cosmos. Astronomers focused the space observatory — which successfully reached its outpost one million miles from Earth this year — on the Saturn-like exoplanet (meaning planet beyond our solar system) WASP-39 b. It’s a hot, gas giant closely orbiting …

Is Earth a self-regulating organism?  New study suggests our planet has a built-in climate control

Is Earth a self-regulating organism? New study suggests our planet has a built-in climate control

The Permian–Triassic extinction event, also called The Great Dying, has certainly earned its nickname. It was the largest mass extinction in the geological record, wiping out between 83 and 97 percent of all species living on Earth. Although the exact cause is debated, extreme volcanic activity that perhaps cooked the planet has been fingered as …

Scientists are looking into this last-minute strategy to save the planet from asteroid disaster

Scientists are looking into this last-minute strategy to save the planet from asteroid disaster

On September 262022, NASA’s Double-Asteroid Redirect Test (DART) made history when it rendezvoused with the asteroid Didymos and impacted with its moonlet, Dimorphous. The purpose was to test the “Kinetic Impact” method, a means of defense against potentially hazardous asteroids (PHAs) where a spacecraft collides with them to alter their trajectory. Based on follow-up observations, …

A new study claims that Mars was covered by 984 feet deep oceans 4.5 billion years ago

The Red Planet was once BLUE: Mars was covered by 984ft-deep oceans 4.5 billion years ago

Now a desolate red desert, a new study has claimed that Mars was once actually predominantly blue. While researchers have long agreed that our red neighbor once held water, just how much water it had was subject to debate. Now, a new study has revealed that 4.5 billion years ago, Mars was covered by 984ft …

Earth can regulate its temperature over hundreds of thousands of years to keep them within a steady range, a new study confirms

Earth CAN regulate its temperature over thousands of years to keep the planet in a habitable range

Earth can regulate its temperature over hundreds of thousands of years to keep them within a steady range, a new study confirms. The planet contains a ‘stabilizing feedback’ mechanism that’s able to keep the climate pendulum from swinging too far in either direction across long timescales. It’s believed this is accomplished through ‘silicate weathering’ – …

Mars: could life itself have made the planet uninhabitable?

Mars: could life itself have made the planet uninhabitable?

Four billion years ago, the Solar System was still young. Almost fully formed, its planets were starting to experience asteroid strikes a little less frequently. Our own planet could have become habitable as long as 3.9 billion years ago, but its primitive biosphere was much different than it is today. Life had not yet invented …

‘Planet killer’ asteroid that evaded detection for years by hiding behind the sun could smash into Earth, scientists predict

A “planet killer” asteroid that is hiding in the glare of the sun has finally been detected, and the giant space rock could smash into Earth one day. The 0.9-mile-wide (1.5 kilometers) “potentially hazardous” asteroid, named 2022 AP7, is one of several large space rocks that astronomers recently discovered near the orbits of Earth swear …

‘Planet killer’ asteroids detected after being hidden by sun’s glare

Astronomers have detected three asteroids in close proximity to Earth, two of which pose a potential threat as “planet killers” because of their larger and hazardous size, but don’t worry, says a NASA expert, they aren’t expected to hurt us . According to findings published in the peer-reviewed Astronomical Journal on Monday, the three asteroids …

Astronomers Find A Fluffy Planet With the Density of a Marshmallow

Astronomers Find A Fluffy Planet With the Density of a Marshmallow

Artist impression of ultra fluffy gas giant orbiting a cool red dwarf. Astronomers have found a planet with the average density of a marshmallow. Along with being a big softie, scientists found that the Jupiter-sized exoplanet would also float if it were hypothetically put in a giant cosmic bathtub. Astronomers using the Kitt Peak National …
