The Sagittarius Window Eclipsing Extrasolar Planet Search (SWEEPS) project conducted by the Hubble Space Telescope recently found 16 new planets. This illustration shows what one of them may look like--a giant, Jupiter-size exoplanet that orbits an unnamed red dwarf star.
This red-hot planet is just 750,000 miles from its star and orbits every 10.5 hours. Scientists speculate that a planet that large and close to a star could have a powerful magnetic field that would trap particles from the sun, creating auroral rings.
A new finding this week brings the total of known planets outside our solar system to 200.
