Since we can’t go back in time to see how our solar system was created, we have to study other stars to try and piece it together. It has recently been discovered that stars and planets actually form at the same time. WE have known how planets form, but the question has been about when they form. The clues astronomers used to start to figure it out came from a white dwarf, which is a dead core of a former sun-like star.
Key Takeaways:
- What dwarfs are made of only helium and hydrogen, though they can contain material from an asteroid that collided with them.
- Many white dwarfs are iron-rich, which suggests that asteroids contained radioactive aluminum-26.
- Researchers concluded these asteroids must have formed very early in the universe, around the same time as the stars.
“Recently, a team of astronomers found evidence that stars and planets actually grow up together, forming at the same time in a solar system’s life.”
