A new exoplanet: Meet GJ 367b, an iron planet smaller and denser than Earth
As our solar system formed 4.6 billion years ago, small grains of dust and ice swirled around, left over from the formation of the Sun. Through time, they collided and stuck to each other. As they grew in size, gravity helped ...

TESS discovers a planet the size of Mars but with the makeup of Mercury
Ultra-short-period planets are small, compact worlds that whip around their stars at close range, completing an orbit—and a single, scorching year—in less than 24 hours. How these planets came to be in such extreme configurations ...
