When astronomers detected the first long-predicted gravitational waves in 2015, it opened a whole new window into the Universe. Before that, astronomy depended on observations

Novel propulsion systems are one of the most important ways to push space exploration forward - literally. Traditional propulsion systems, like chemical rockets, are good at getting spacecraft out of gravity wells but not so great at traveling in free space. More modern

Saturn’s moon Titan is perhaps one of the most fascinating moons in the Solar System. It’s the second largest of all the moons in our planetary neighbourhood and is the only one with a significant atmosphere. It’s composed of 95% nitrogen and 5% methane and is 1.5 times as

New images from NASA's Juno spacecraft make Io's nature clear. It's the most volcanically active world in the Solar System, with more than 400 active volcanoes. Juno has performed multiple flybys of Io, and images from its latest one show an enormous hotspot

To the casual observer, the Sun seems to be the one constant and never changing. The reality is that the Sun is a seething mass of plasma, electrically charged gas which is constantly being effected by the Sun’s magnetic field. The unpredictability of the activity on the Sun

A team of astronomers have discovered a rather curious exoplanetary system that has two gas giant planets that are messing up each other’s orbit! On of them is 3.8 times the mass of Jupiter and completes an orbit every 82 days, the other is just 1.4 Jupiter masses. Hiding in

Comet G3 ATLAS wows southern hemisphere observers and Universe Today readers before it fades from view.

Comets are always a true celestial treat to track. In a clockwork cosmos, the appearance of a potentially bright new comet is always a celestial question

What would you do for fun on another planet? Go ballooning in Venus’ atmosphere? Explore the caves of Hyperion? Hike all the way around Mercury? Ride a toboggan down the slopes of Pluto’s ice mountains? Or watch clouds roll by on Mars?

All those adventures, and more, are

The study of asteroid samples is a highly lucrative area of research and one of the best ways to determine how the Solar System came to be. Given that asteroids are leftover material from the formation of the Solar System, they are likely to contain vital clues about how

Though it's a cold, dead planet, Mars still has its own natural beauty about it. This image shows us something we'll never see on Earth.

Mars has only a thin, tenuous atmosphere, and most of it (95%) is carbon dioxide. When Martian winter arrives, CO2 freezes
