While the mechanics of a total solar eclipse are actually rather mundane, different flavors of this phenomenon make some very sophisticated science possible. original

In the search for planets similar to our own, an important point of comparison is the planet’s density. original

Originally aired on February 27, 2009, a conversation on the Kepler Mission with Principal Investigator William Borucki, Deputy Principal Investigator David Koch, and Kepler Science Council Member Alan Boss from the Carnegie Institute of Washington. original

NASA’s Kepler space telescope team has released a mission catalog of planet candidates that introduces 219 new planet candidates, 10 of which are near-Earth size and orbiting in their star’s habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet. original

This diagram illustrates how planets are assembled and sorted into two distinct size classes. First, the rocky cores of planets are formed from smaller pieces. Then, the gravity of the planets attracts hydrogen and helium gas. Finally, the planets are “baked” by the starlight and lose some gas. original

This sketch illustrates a family tree of exoplanets. Planets are born out of swirling disks of gas and dust called protoplanetary disks. The disks give rise to giant planets like Jupiter as well as smaller planets mostly between the size of Earth and Neptune. original

Researchers using data from the W. M. Keck Observatory and NASA’s Kepler mission have discovered a gap in the distribution of planet sizes, indicating that most planets discovered by Kepler so far fall into two distinct size classes: the rocky Earth-size and super-Earth-size (similar to Kepler-452b), and the mini-Neptune-size (similar to Kepler-22b original

Kepler was the first NASA mission capable of detecting Earth-size planets, using the transit method, a photometric technique that measures the minuscule dimming of starlight as a planet passes in front of its host star. original

The population of exoplanets detected by the Kepler mission (yellow dots) compared to those detected by other surveys using various methods: radial velocity (light blue dots), transit (pink dots), imaging (green dots), microlensing (dark blue dots), and pulsar timing (red dots). original

There are 4,034 planet candidates now known with the release of the eighth Kepler planet candidate catalog. Of these, 2,335 have been confirmed as planets. The blue dots show planet candidates from previous catalogs, while the yellow dots show new candidates from the eighth catalog. original

Highlighted are new planet candidates from the eighth Kepler planet candidate catalog that are less than twice the size of Earth and orbit in the stars’ habitable zone – the range of distances from a star where liquid water could pool on the surface of an orbiting planet. original
