Would you guess that the Earth is spinning at 1,000 mph around its axis and at the same time hurtling through space on its orbit around the Sun at 67,000 mph? Here’s why you don’t feel all that motion.
A planetary scientist walks through the sensors and systems that went into the recent detection of potential biosignatures.
The Moon influences ocean tides – and ocean tides, in some ways, influence the Moon back.
Unique, spotted rocks in Mars’ Jezero Crater could indicate that the planet once hosted life.
The Viking missions paved the way for future Mars missions and helped researchers understand the red planet’s climate and geology.
It turns out that Mars has a similar interior structure to Earth.
Microbes hidden deep in ocean volcanoes could resemble life on other planets or moons.
Keeping Earth safe from asteroids isn’t just spotting them – it’s also helping people understand what a high-impact probability with Earth means.
Mars isn’t a bright, fire-engine red, but the iron oxide in its rocks makes it appear redder than other planets, especially from afar.
Under the proposed budget, several major projects, such as the Mars Sample Return and the Space Launch System, would face cancellation.
NASA hasn’t landed humans on Mars yet. But thanks to robotic missions, scientists now know more about the planet’s surface than they did when the movie was released.
NASA’s learned a lot about the Moon since Apollo. But a perfect landing still requires incredible planning and scientific precision.
NASA’s Curiosity rover has spotted carbon-containing minerals that can tell scientists more about what ancient Mars’ atmosphere may have looked like.
The Earth started as a mixture of gas and dust around the Sun and grew as it collided with asteroids and dust particles.
The exoplanet K2-18b could harbor a massive ocean, but scientists will need to study the planet more to see if it’s really likely to host life.
Water-rich meteorites contain key ingredients for life, yet they barely appear in meteorite collections. Recent research using shooting stars may explain why.
The number of known moons in our Solar System has been rising for centuries, but astronomers say it has probably peaked – for now.
Hundreds of millions of years ago, rocks crushed under kilometres of ice injected vital nutrients into Earth’s oceans.
New findings reveal that a NASA mission traveled to an asteroid that may have once been covered in salty lakes containing organic molecules.
