Occultation occurs when one celestial body — for instance, a moon or a planet — aligns with another. Striking images of occultation give us an unusual glimpse of the traffic in our cosmic backyard.
We've found about 300 planets beyond our solar system, using indirect methods that calculate their presence. Now Hubble has captured the first visible-light picture of a planet around another star.
"Hubble's Next Discovery — You Decide" puts control of the telescope in the hands of the public. Dr. Summers reviews the candidates for Hubble viewing and describes their intriguing features.
Matter warps the space around it, according to Einstein. We use this effect to our advantage in cosmic observations, using "gravitational lenses" to view galaxies ordinarily beyond the reach of our telescopes.
Jupiter's Great Red Spot, a whirling storm on the gas giant planet's surface, has been one of the planet's most recognizable features for centuries. But look out — company is on the way.
