New research suggests Saturn’s rings may be surprisingly young.
There’s nothing weird happening with Mercury. In fact, most days of the year there’s at least one planet in retrograde.
Not all lunar eclipses are alike. An astronomer explains the science behind the slight dimming of the Moon on May 5, 2023.
The current race to the Moon is opening up opportunities for lunar astronomy.
One of Jupiter’s moons, Ganymede, could contain more water than the Earth.
History might give you the impression astronomical discoveries were only done by men. But women were participating in scientific expeditions of eclipses too, even though it wasn’t easy.
The newly discovered comet C/2023 A3 Tsuchinshan-ATLAS is anticipated to be spectacularly bright late next year. But it’s important to temper our expectations.
In 2021, searchers recovered a meteorite that fell over the UK just hours earlier. Scientists have now reconstructed its story.
Our Mars rovers might not be sensitive enough to detect signs of life. But lessons from Antarctica might make future missions more successful.
The Solar System as we know it doesn’t really make sense without a ninth planet. So then why can’t we find it?
Within hours of its landing, samples of the Winchcombe meteorite had been recovered and its origins tracked back beyond Mars to the asteroid belt.
A study has found that microorganisms living on Mars billions of years ago may have left the planet uninhabitable.
Believe it or not, this sort-of happened before in Earth’s history – and now we have the Moon.
In the void of interstellar space, the most distant emissary of humankind carries a message that will last for billions of years.
The unusual planetary system has a host star orbited by two giants. One has an incredible odd route around its star. And the other (unlike our own gas giants) is hellishly hot.
When the meteor exploded into pieces above New Zealand, it produced a shock wave strong enough to be picked up by earthquake seismometers. But any fragments have likely dropped into the ocean.
A curious kid asks: Why does it matter if Pluto is a planet or a dwarf planet?
Could the Tau Herculid meteor shower put on a spectacular show next week? Only time will tell.
Mars is the fourth planet from the Sun and one of our closest neighbors in space. But it’s not a very welcoming place for an Earthling to visit.
