Coupled with 3D printing, biomining the Moon or Mars with microbes could sustain human colonies without constant re-supply from Earth.
The Schumann resonances are the background hum of the entire planet. But they don’t affect humans in any way.
We give it the flight plan, and it takes care of the rest. It has to. Here’s why. No matter how advanced our technology becomes, there are certain limits that can […]
There will always be “wolf-criers” whose claims wither under scrutiny. But aliens are certainly out there, if science dares to find them.
Google maps won’t guide you to Mars – but will your compass work in space?

Shortly after planet Earth formed, life took a permanent hold on our surface. But just how common is such an outcome?
Communication with home will be difficult on long-haul space flights. The longer this isolation goes on, the more detached a crew becomes.
Nearly 200 orbital launches are scheduled for 2022.
Based on the atoms that they’re made out of, the innermost planet should always be the densest. Here’s why Earth beats Mercury, hands down.
The far side of the Moon is incredibly different from the Earth-facing side. 63 years later, we know why the Moon’s faces are not alike.
The classic picture of Jupiter’s great rocky core might be entirely wrong.
The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date.
In revolutionary Russia, a group of forward-thinking philosophers offered an alternative to both futurism and communism.
It is humanity’s biggest step yet into the Solar System.
Scientists have long puzzled over how Mars, a cold and dry planet, was once warm enough to support liquid water.
Despite the enormous mass of the Earth, simply depleting our groundwater is changing our axial tilt. Simple Newtonian physics explains why.
Preventing scurvy is not just a problem in the Antarctic.
While Mars is known as a frozen, red planet today, it has all the evidence we could ask for of a watery past, lasting for approximately the first 1.5 billion […]
A tiny layer of microscopic dust is the only reason it appears red. When we look out at our planet Earth from space, we see a myriad of diverse colors. The […]
Our views from the red planet’s surface are more spectacular than ever. Ever since the earliest spaceflight, humanity has reached for Mars. This photo composite shows Meande Ring, a river on […]
Some fascinating observations of K2-18b have come along with horrendous, speculative communications. There’s no evidence for oceans or life.
There are plenty of life-friendly stellar systems in the Universe today. But at some point in the far future, life’s final extinction will occur.
When high-anxiety situations arise in the workplace, we tend to react by fighting, fleeing, freezing, or fawning — but there’s a hidden fifth option.
Sound waves behave quite differently on Mars than on Earth.

In 1924, Edwin Hubble found proof that the Milky Way isn’t the only galaxy in the Universe.
Speculation about the existence of aliens goes all the way back at least to the Greek philosophers. Their arguments will sound familiar.
Water is vital for life. Luckily for spacefaring humans, the solar system is full of it.
The findings include signs of flash flooding that carried huge boulders downstream into the lakebed.
