From the tallest cliff in the solar system to its largest impact basin, geological processes on other worlds are very similar to those on our own planet.

The reason bigger objects in space are round and smaller ones aren’t boils down to gravity. And it’s the same reason mountains on Earth can only grow to a certain height
Mars, Venus and the crescent Moon will all come together in the sky just after sunset on Tuesday.
New research suggests that Venus’ crust is broken into large blocks – the dark reddish–purple areas – that are surrounded by belts of tectonic structures shown in lighter yellow–red.

Researchers used decades-old radar data and found that some low-lying areas of Venus’ crust are moving and jostling. This evidence is some of the strongest yet of tectonic activity on Venus.
It can stretch your mind to ponder what’s really out there.

It has only been in the past century that weather prediction on Earth has advanced enough to work two weeks in advance. Predicting space weather, however, is only reliable an hour in advance.

A recent study shows that the Earth’s water could come directly from the oxygen and hydrogen present in the rocks that formed it, and not from a late supply by asteroids.
From the birth of Jesus Christ to Newton’s discovery of gravity, great conjunctions of Jupiter and Saturn have many notable connections in human history.

A severe climate change event on Venus may have transformed an Earth-like climate to the current uninhabitable-to-humans state.

COVID-19 may have messed up school and shut down a lot of entertainment venues. But you can still brighten things up by doing a little stargazing at night, an astronomer says.
Unlike Earth’s atmosphere, Jupiter’s ‘sky’ hosts magnificent shades of orange, white, brown and blue.
