Years ago when astronomers were first planning NASA's Chandra X-ray Observatory, they didn't have planets in mind. Planets were too peaceful for x-ray astronomy. Chandra was going to reveal colliding galaxies, sizzling-hot whirlpools around black holes, exploding stars--in other words, violent sources of high-energy x-rays. Not planets.
that sound interesting.
all who are not knows what Chandra is
