Chemical changes inside Mars' core caused it to lose its magnetic field. This, in turn, caused it to lose its oceans. But how?

Mars, the red planet, was a world we knew almost nothing about until our first spacecraft visited it. In just ~50 years, how far we've come!

A next-generation instrument on a delayed rover may be the key to answering the question of life on Mars.

Compared to Earth, Mars is small, cold, dry, and lifeless. But 3.4 billion years ago, a killer asteroid caused a Martian megatsunami.

It could cut the time needed to reach Mars in half.

Organic molecules can be produced by living or non-living systems. But the recent findings are very intriguing.

There's an extremely good chance that there is, or at least was, life on Mars. But is it native to Mars, or did it originate from Earth?

We may have discovered alien life already but rejected the evidence too quickly because it seemed false at first glance.

In one experiment, the Viking landers added water to Martian soil samples. That might have been a very bad idea.

Data from the Zhurong rover suggests the Red Planet was wet more recently than we thought.

There's a whole lotta shakin' goin' on beneath the single plate of Mars.

A new study of Martian dust gives insights into the ancient Martian climate. The findings hint at a wetter world.

Was there ever life on Mars? Is there life on Mars now? Did it originate there or here, on Earth? All possibilities are fascinating.

Thanks to a couple of rovers, we know Mars was once blue.

It's not about fairness. It's about using every possible advantage.

The high pitches from the flute and the harp would reach your ears before the notes from the tuba and the cello.

Dead whales inspire a way to find extraterrestrial life on Mars.

Researchers have discovered 830-million-year-old microbes living inside a salt rock on Earth. Could the same occur on Mars?

Experts believe they could cut the time it takes a rocket to reach Mars by up to 25%, shaving about two months off the trip.

Yes, NASA's Perseverance rover found organics on Mars. So did Curiosity. Unfortunately, that doesn't mean anything in the search for life.

In the night sky for March of 2022, only stars and the Moon, not planets, will greet you. The real show, however, arrives just before dawn.

The giant impact theory suggests our Moon was formed from proto-Earth getting a Mars-sized strike. An exoplanet system shows it's plausible.

Our research on a Martian meteorite provides new clues about early surface conditions on the red planet.

Instead of worshipping Yahweh, the devotees were perhaps dedicated to Mars and Jupiter.

Water on Mars is key for human survival on the Red Planet, not just for drinking but for growing food and making fuel and oxygen.

No planet enters retrograde more frequently than Mercury, which does so 3-4 times each year. Here’s the scientific explanation for why.

The surface and atmosphere is colored by ferric oxides. Beneath a very thin layer, mere millimeters deep in places, it's not red anymore.

One book will gather all topics on the search for life in the Cosmos.

"You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it."

The first human that isn’t an Earthling could be in our lifetime.
