“Mars wouldn’t be nearly this dusty if it wasn’t for this one enormous deposit that is gradually eroding over time and polluting the planet, essentially.”
ESA’s Mars Express spacecraft has discovered the 1st evidence for a subsurface liquid lake on Mars. If it exists, this lake is likely salty and cold, but possibly habitable for some microorganisms.
Not now, but billions of years ago, microbes might have thrived in water pools on the moon until its surface became dead and dry.
It had been theorized that some young stars might devour their planets. Now astronomers have the 1st solid evidence – from the Chandra X-ray Observatory – of just such an event caught in the act.
Two billion years ago, the Andromeda galaxy – closest large spiral galaxy to our Milky Way – might have eaten another large galaxy.
Io is small, but it’s the most volcanically active world in our solar system. It has hundreds of active volcanoes. Now the Juno spacecraft has found one more.
Raging, planet-wide dust storms – like the one going on now – happen only every 6 to 8 years on Mars. Here’s how NASA spacecraft are studying it, plus a cool before-and-after video!
Why do people persist in denying that human beings landed on the moon?
Today is the 49th anniversary of humanity’s historic first steps on the moon. The story in pictures, here.
When the Apollo astronauts returned from the moon, the dust that clung to their spacesuits made their throats sore and their eyes water. Lunar dust is made of sharp, abrasive particles, but how toxic is it for humans?
