Warmth on sunny days could be a major trigger for instigating dust storm activity on Mars.

We may be racing against the clock to identify signs of life on Mars — and it's all because of cosmic rays.

NASA is developing autonomous software to recognize faults and hazards on worlds like Europa, and prevent or fix them without having to await commands from Earth.

A team of astronomers just spotted dozens of tiny asteroids in JWST date — including the smallest ever seen in the main belt between Mars and Jupiter.

"Artemis astronauts or robots in the south pole region may be able to closely study rocks from deep within the moon’s mantle or crust — materials that are typically impossible for us to access."

Studying how much the Uranian moons sway in orbit may reveal whether or not they have oceans inside of them. NASA is in the early stages of planning a mission to do just that.

Watch the moment an impulsive X-class solar flare explodes from the sun in a dramatic eruption.

Space weather experts warn that solar activity will persist or even increase after solar maximum has ended and we enter a phase of the solar cycle dubbed the "battle zone."

The Arctic's ice cover could dip below a crucial threshold as soon as 2027, and will do so inevitably in the next 20 years if greenhouse gas emissions continue, scientists warn.
