Winn (Massachusetts Institute of Technology) also used the Subaru Telescope's HDS to independently observe the HAT-P-7 system and likewise concluded that extrasolar planet HAT-P-7b has a retrograde or polar orbit.
Kane and his colleagues were able to confirm its extreme eccentricity and the rest of its orbital parameters as part of the Transit Ephemeris Refinement and Monitoring Survey (TERMS), a project led by Kane to detect extrasolar planets as they pass in front of their stars.
But co-author Professor Geoffrey Marcy, from UC Berkeley, who pioneered the search for extrasolar planets in the 1990s, cautioned that just because an Earth-size planet is in the habitable zone, that does not necessarily make it hospitable to life.
They have demonstrated that, by measuring alterations in the speed at which an extrasolar planet floats in front of its starve transit timing duration (TTD)--a moon hunter unambiguously can detect the desired exomoon.
In 1992, astronomers used a similar method to make the first discoveries of extrasolar planets.
In 1991, English astronomer Andrew Lyne and his team announced the detection of planets around a pulsar (a dead star), which seemed to be the first extrasolar planets.
Therefore, oxygen had been thought to be an essential biomarker for life on extrasolar planets.
The new extrasolar planet is too small for telescopes to take a picture of it.

A newly discovered extrasolar planet is not only the smallest yet found, but also the first confirmed to be made entirely of rocky material, Natalie Batalha of San Jose State University in California reported January 10.
EPOXI is a combination of the names for the two extended mission components: a search for extrasolar planets during its cruise phase to comet Hartley 2, called Extrasolar Planet Observations and Characterization (EPOCh), and the eventual flyby of the comet, called the Deep Impact eXtended Investigation (DIXI).
