Curious Kids: is the sky blue on other planets?

Atmospheres can be all different colours, depending on what’s in them.
The air up high is just really bad at ‘holding’ onto the radiation coming from the Sun, and the warmth passes straight through it on its journey toward the ground. Kevin Spencer/flicr

Curious Kids: why is air colder the higher up you go?

It helps if you imagine the ground here on Earth as a big heater. It keeps us warm, and if you move away from the heater you feel cold.

New findings on ocean warming: 5 questions answered

According to a new study, the oceans have absorbed more heat from climate change than previously thought. This could mean the Earth will warm even faster in the future than scientists have predicted.

Capturing the shadow of Saturn’s moon Titan from right here on Earth

Titan is more than a billion kilometres from our Sun but occasionally it’s shadow can be seen here on Earth, with the right technology. That’s what scientists gathered in Western Australia to observe.
