The primary objective of CHEOPS is to better understand the planets that we’ve already found. And its mission is now in full swing.
A young reader asks: Is Pluto a planet?
NASA scientists have discovered a new planet orbiting around a nearby star that is in a habitable zone. But does this planet have liquid oceans that can support life?
Many people are still upset that Pluto was demoted from being a planet. But definitions of various celestial objects are fairly fluid. So whether it is an asteroid or moon or planet is up for debate.
Kepler-452b is sometimes called 'Earth 2.0', but there's a lot we still don't know about it.
It is always exciting to discover new planets beyond our Solar System. Now a planetary astrophysicist is using a star's chemistry to predict which ones are likely to host giant planets.
The source of water on Earth, the Moon and planets in our solar system is hotly debated. Some in the planetary science community argued that it came from asteroids and comets. Now they have proof.
The Earth's core is cooling down, and one day it will be completely solid – when that happens, Earth might look a lot like Mars.
The upper atmosphere of Venus is the most Earth-like extra-terrestrial location in the solar system. It could even host life.
Indigenous communities lived in the Amazon for thousands of years without chopping down their forests.
How long before we find a planet just like our own?
Sonification is a technique for converting data into sound. It could transform the study of distant worlds.
