In countries that identify predominantly as Christian, scripture and its interpretations carry serious sociopolitical weight.

moon of Enceladus.
Earth is a relatively dry planet compared to some of the other ocean worlds in our Solar system. Life needs water so what about life on these other places?
Have we really discovered other “Earth-like” planets orbiting around other stars? Understanding what we do and do not know about exoplanets is the key to answering this question.

Over the last 20 years, advances in the field of exoplanet discovery have excited the imaginations of scientists and enthusiasts alike. But we're in position to know yet whether a planet is habitable.
What’s north would become south.
Are we headed to a magnetic reversal and all the global disruption that would bring? Enter archaeomagnetism. A look at the archaeological record in southern Africa provides some clues.
Artist’s impression of an ice age.
The Earth's orbit has driven ice ages in the past but those days could be over.
Enjoy the full moon’s glow.
Full moons are good reason to look up – and the one on Nov. 14 is no exception. But here’s why you likely won’t see something shockingly different from other full moons you've observed over the years.
How to save the Earth from an asteroid strike.
Large asteroid hits on Earth have the potential to wipe out humanity so knowing how to detect and deflect them is vital. But we know very little about the interior make up of many asteroids.

Our growing dependency on satellites for all forms of communication has made the problem of space weather even more acute.

Fifty years on from a groundbreaking paper, geophysicists have progressed from believing continents never moved to thinking that every movement may leave a lasting memory on our planet.
Solar flare on August 31, 2012.
Life on Earth may have started with a bit of sunshine and showers, followed with a light breeze of laughing gas and a sprinkle of hydrogen cyanide.
An artist’s concept of select planetary discoveries made to date by NASA’s Kepler space telescope.
The number of known exoplanets doubled this week to more than 3,200. But why have only a handful of these those new planets caught people's imagination?
An artist’s illustration of Kappa Ceti whose stellar winds are 50 times stronger than our sun’s. Any Earth-like planet would need a magnetic field to protect its atmosphere if it was to stand a chance of hosting life.
In the search for life on other planets in the universe we need to find the right kind of star, and it needs to have the right kind of space weather.
On February 29, night suddenly becomes day.
Was it a UFO? Was it a high-tech plane? Here's what lucky people really saw over Scotland on February 29.
If you’re looking for life, you’d do well to look for some moons.
As the list of known planets beyond our solar system grows, the search for their moons is intensifying. One reason: they might hold the key to finding life elsewhere in the universe.
Once there was water….
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
Ain’t half hot: but where’s it heading?
Astrophysicists found out after the January 2014 solar flare that their predictions of solar weather were not very accurate. Here's the fix (kind of).
TshepisoSAT, Africa’s first nano-satellite developed by students and staff at the Cape Peninsula University of Technology.
Nano-satellites are small and cool enough to inspire youth to consider careers in science, technology, engineering and mathematics.
Pale Blue Dot – Earth, imaged by Voyager 1 from 6 billion kilometres away.
From a big blue marble to a tiny dot in space -- reflections on our images of Earth.
Are you afraid of the dark matter?
European Southern Observatory
Every 30 mil years, Earth has to deal with more comet crashes from space and more intense geological activity from within. Dark matter may be the culprit in these episodes that can cause mass extinction.
No Earths were harmed in the making of this image.
The discovery of a thickly viscous layer which traps sinking plates below Earth's surface has wide implications, not least as a cause of earthquakes.
