Earth and solar system may have been shaped by nearby exploding star

A new explanation for the solar system's radioactive elements suggests Earth-like planets might be found orbiting up to 50 per cent of sun-like stars

Close brush with two hot stars millions of years ago left a mark just beyond our solar system

Nearly 4.5 million years ago, two large, hot stars brushed tantalizingly close to Earth's sun. They left behind a trace in the clouds of gas and dust that swirl just beyond our solar system—almost like the scent of perfume after someone has left the room.

This startup raised millions to beam solar power from space after dark

Okay, it's not quite that common an occurrence, but there are indeed a number of firms giving this a go. The latest to join the fold is Overview Energy, a Northern Virginia-based startup that's raised US$20 million to try transmitting solar power from satellites down to solar panels on Earth, enabling a 24/7 supply.

Supernova immersion model suggests Earth-like planets are more common in the universe

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a nearby supernova (the massive explosion of a star near the end of its life) bathed it in cosmic rays containing the radioactive ingredients to make rocky,
