By studying decay of bound-state beta decay of thallium-205 (205Tl81+), scientists can better understand the timing and conditions in the early solar system, giving clues about when the sun formed.

Discover interesting facts about the sun, the solar system's central star that supports all life on Earth.

How was the sun formed? Our solar system formed from the gravitational collapse of a “dense” giant molecular cloud of gas and dust, composed mainly of hydrogen, a bit of helium, and about one ...

That’s how stars like our sun formed. It’s how planets and galaxies and everything else in the universe got there. It’s how stars form today, too.

Analysis of an ancient meteorite suggests that rocky planets both near and distant from the sun may have formed at the same time, challenging current models of our solar system’s evolution.

The sun formed around 4.5 billion years ago. At that time, the area of the Milky Way galaxy that would become the solar system was a dense cloud of gas — the leftovers of an earlier generation ...
