A team of researchers from the Johns Hopkins University Applied Physics Laboratory, North Carolina State University and NASA, has proposed, via whitepaper, that NASA should direct its Mars-bound spacecraft to fly by Venu...

Imagine Earth. Now fill the skies with thick, sun-obscuring clouds of sulfuric acid; boil off the oceans by cranking up the temperature to 900 degrees Fahrenheit (nearly 500 degrees Celsius), and boost the air pressure h...

A pair of linguists recently did a study, which appeared in an ESA-associated journal, that discusses how interstellar travel could lead to changes in our language. The post Languages Will Change Significantly on Interst...

You’ve gotta hand it to NASA, and to the German Aerospace Center (DLR.) They’ve been struggling for over a year to get the InSight Lander’s Mole working. There’ve been setbacks, then progress, then more setbacks,...

After putting on a great show in our evening sky during the first half of this year, dazzling Venus puts on a spectacular showing for early morning risers for the balance of 2020.

It depends on whether the planet's atmosphere is predominantly filled with gas or dust particles.

America's second satellite stopped communicating with Earth in 1964, but it will stay in orbit for centuries.

Earth is a radiation cocoon. Inside that cocoon, the atmosphere and the magnetosphere keep us mostly safe from the Sun’s radiaition. Some ultraviolet light gets through, and can damage us. But reasonable precautions li...

Russia's Progress 74 (74P) cargo craft departed the International Space Station today leaving four spaceships from the U.S., Russia and Japan parked at the orbital lab....

Each year, dust from the Sahara Desert blows off Africa and across the Atlantic, but most years that plume isn't so massive it's nicknamed "Godzilla."

The cold, dark chaos of space is filled with mystery.

Rocky planets that formed early in our Milky Way galaxy's 13.2-billion-year history have a better chance of supporting life than worlds that were later to the party, a new study suggests.
