Webb presents best evidence to date for rocky exoplanet atmosphere
Researchers using NASA/ESA/CSA James Webb Space Telescope may have detected an atmosphere surrounding 55 Cancri e, a rocky exoplanet 41 light-years from Earth. This is the best evidence to date for a rocky planet atmosphere outside our solar system......»»
"Lost" spy satellite orbited Earth undetected for 25 years—until now, scientists say
An experimental spy satellite that was deemed "lost" after eluding detection for decades has finally been found. "The S73-7 satellite has been rediscovered after being untracked for 25 years," astrophysicist Jonathan McDowell said in an April 29 post.....»»
Study reveals new mechanism to explain how continents stabilized
Ancient, expansive tracts of continental crust called cratons have helped keep Earth's continents stable for billions of years, even as landmasses shift, mountains rise and oceans form. A new mechanism proposed by Penn State scientists may explain ho.....»»
Computer models suggest modern plate tectonics are due to blobs left behind by cosmic collision
A small team of geologists and seismologists at the California Institute of Technology has found evidence via computer modeling that suggest giant blobs of material near the Earth's core, believed to have been created by a cosmic collision 4.5 billio.....»»

Geologists reveal mysterious and diverse volcanism in lunar Apollo Basin, Chang"e-6 landing site
The far side of the moon is a mysterious place that is never visible from the Earth. The most remarkable feature of the moon is its asymmetry between the lunar near side and far side in composition, crust thickness, and mare volcanism. Scientists hav.....»»
What can early Earth teach us about the search for life?
Earth is the only life-supporting planet we know of, so it's tempting to use it as a standard in the search for life elsewhere. But the modern Earth can't serve as a basis for evaluating exoplanets and their potential to support life. Earth's atmosph.....»»

Shining a light on untapped lunar resources
Near the moon's south pole lies a 13-mile wide, 2.5-mile-deep crater known as Shackleton, named for Antarctic explorer Ernest Shackleton. Shackleton—and craters like it—may contain untapped resources that can be accessed with lunar mining......»»
Listening to giants: The search for the elusive Antarctic blue whale
Blue whales are the largest animals on Earth, measuring up to 30 meters long and weighing up to 200 tons—as much as a Boeing 787. Yet it's the sound they make, not their size, which gives their location away......»»
