In a world first, NASA has crashed a spacecraft into an asteroid in an attempt to push the rocky traveler off its trajectory. The Double Asteroid Redirection Test – or DART – is meant to test one potential approach that could prevent an asteroid from colliding with Earth. David Barnhart is a professor of astronautics …

Discovered by humanity less than 100 years ago, Pluto has largely remained an enigma ever since. It was not until 2015 that the first spacecraft from Earth – an uncrewed probe sent by NASA – made a flyby of the distant planet, passing within 7,750 miles of the surface after traversing three billion miles since …

We can learn a lot about climate change from Venus, our sister planet. Venus currently has a surface temperature of 450℃ (the temperature of an oven’s self-cleaning cycle) and an atmosphere dominated by carbon dioxide (96 per cent) with a density 90 times that of Earth’s. Venus is a very strange place, totally uninhabitable, except …

The Parker Solar Probe captured an absolutely stunning glimpse of Venus during its third close flyby of the planet in July 2020, as seen in a newly released image from NASA and the mission’s science team. Although the Sun is the focus of the Parker Solar Probe’s seven-year-long mission to “touch” the Sun and fly …

Japanese space scientists are positively gleeful as they have now confirmed that their ambitious Hayabusa2 spacecraft successfully collected over 5 grams of pristine black as coal soil and rock samples gathered from the ancient near-earth asteroid Ryugu in a re-entry capsule that parachuted safely to Earth earlier this month after a six-year roundtrip scientific journey …

In astronomy, we have a common saying: “good luck, and clear skies”. For an eclipse chaser like me, this is especially important. We have two minutes and no second chance – one small cloud can spoil everything. Thousands of tourists turn up to see them, along with a few dozen scientists, for which the eclipse …
