There's enough dissolved oxygen in the salty lake below Mars' surface to support simple lifeforms such as sponges. Here's what that means for space exploration.
The five planets visible to the naked eye since ancient times are putting on a dazzling display this month, in a night-sky dance along with the Moon.
Studies from our own planet shed light on whether there could be life in a subglacial lake on Mars.
The moon is our closest neighbour and our best hope for building capacity to explore space.
Could Canadian technology play a part in the newly announced U.S. Space Force? A team at McMaster University has developed an instrument that could keep Space Force troops safe from radiation.
Compared to Earth, more "oomph" is required to bring magma to the surface of Mars, and this is probably why we haven't seen any recent eruptions on the red planet.
Augmented reality technology could help recreate familiar sensory experiences from Earth.

The longest lunar eclipse this century, and other special features such as Mars looking spectacular will be seen.
If humans are to live on Mars they will need a stable supply of food. Earth plants are not suited to the Mars climate but we can engineer plants that are.

What is Mars made of? We hear from a scientist who will be part of the team analysing 'marsquake' seismic data and orbital imagery from the InSight mission to the red planet.
Cosmic radiation is much higher today than it was during the Apollo era.
The InSight Lander mission to Mars is preparing for launch in May 2018. But there are seven (or eight) other planets to explore: why have we such a hang up on Mars?
