Finding Planets with Gravitational Lensing
Get a lesson in Einstein's general theory of relativity to understand an effect called gravitational microlensing, which allows astronomers to deduce a planet's existence without recording any light from the planet or its host star. This technique reveals exoplanets that would otherwise go undetected.
Living with a Giant Star
In billions of years, the Sun will expand into a red giant, possibly engulfing Earth. Learn how planet-finding techniques give astronomers insight into the processes inside giant stars. Then study the planets around these behemoths for clues about Earth's ultimate fate.
The Transits of Exoplanets
A tiny percentage of exoplanets can be detected transiting--or passing in front of--their host stars. Combined with Doppler shifts, transits provide information about a planet's size, mass, density, and likely composition. Learn how ambitious amateur astronomers can use this detection technique in their own backyards.
The Misplaced Giant Planets
Investigate 51 Pegasi b, the first planet detected around a Sun-like star, which shocked astronomers by being roughly the size of Jupiter but in an orbit much closer to its star than Mercury is to the Sun. Probe the strange characteristics of these "hot Jupiters," which have turned up around…
Pioneers of Planet Searching
Chart the history of exoplanet hunting--from a famous false signal in the 1960s, through ambiguous discoveries in the 1980s, to the big breakthrough in the 1990s, when dozens of exoplanets turned up. Astronomers were stunned to find planets unlike anything in the solar system.
