Conditions in the early universe might have enabled rocky planets with water to form much earlier than anticipated, potentially allowing life to begin sooner too. Astrophysicists studying the ...

Scientists have long overlooked white dwarfs as hosts for habitable exoplanets, assuming their lack of fusion would make life impossible. But new climate models challenge that idea, showing that ...

White dwarf stars could host habitable planets. Fast planetary rotation reduces cloud cover, keeping surface temperatures stable.

ALIENS could discover humans on Earth by spotting one of 12 signs, scientists say. Topping the list is a clue that could be seen by extraterrestrials from a mammoth 12,000 lightyears away. The ...

The Dynamically Stable Large Space Structures via Architected Metamaterials was granted a NIAC award by NASA at the beginning ...

For now, life is flourishing on our oxygen-rich planet, but Earth wasn't always that way – and scientists have predicted that ...

The climate on such a world must be beyond bizarre. A super-Earth planet that dips in and out of its star's habitable zone has been discovered just 19.7 light-years away. The planet, known as HD ...

Scientists challenge the idea that intelligent life is rare. They argue that evolution follows planetary changes, not random ...
