Supernovae

An exploding star has given researchers a rare chance to find out what the inside of old stars looks like, according to an international study.

International researchers suggest that water might have formed a mere 100-200 million years after the Big Bang, far earlier than previously thought, and it might have been a key part of the formation of our universe's first galaxies.

For the last hundred years or so, physicists believed the Universe was expanding equally in all directions, and used the concept of "dark energy" as a placeholder to help explain what they couldn't understand.
