A University of California-led research team has discovered 28 new planets deep in the Milky Way, circling stars not unlike our own - leading them to conclude that our solar system may not be so special after all.
"The sun and Earth is not a rarity," said Geoffrey Marcy, professor of astronomy at UC-Berkeley, estimating that there may be at least 20 million to 30 million solar systems within the Milky Way galaxy. "A family of planets orbiting a single star is a very common occurrence."
