This begs the question of whether all the Jupiter -
like planet detections from the different methods are really consistent with each other.

By next spring, the
planet - hunting space telescope known as Kepler — rejected by NASA three times but then approved after those initial
detections of exoplanets in the 1990s — will most likely report the discovery of the first known Earth -
like planet in an Earth -
like orbit.
A solid
detection of an Earth - size
planet in a place called the «Goldilocks zone» because it's neither too hot nor too cold for liquid water to exist — even if the researchers do use the word candidate to describe a
detection with Kepler - catalog -

This marks the first
detection of an atmosphere around an Earth -
like planet other than Earth itself, and thus is a significant step on the path towards the
detection of life outside our Solar System.
Short - periodic Neptune -

planets, whose transit
detection still eludes us in most cases, CoRoT - 7b being the first possible member of the remaining population of nuclei of gas -
planets that have undergone significant evaporation.
In addition, she is working on the development of new observational techniques for the
detection and characterization of the atmospheres of Earth -
like planets to be discovered by the upcoming NASA TESS mission.
«While this is not the
detection of life on another
planet,» lead author Dr. John Southworth, an astrophysicist from Keele University in the UK, said in a statement, «it's an important step in the right direction: the
detection of an atmosphere around the super-Earth GJ 1132b marks the first time that an atmosphere has been detected around an Earth -
like planet other than Earth itself.»

detection of Earth -
like planets.

planets and planetary systems found by Kepler.
«There's a tantalizing incentive: it's possible that some potentially habitable
planets like Earth, which are relatively small and orbit around relatively dim stars, might be hiding just below the traditional
detection threshold — there might be hidden gems still undiscovered in the Kepler data!»
Furthermore, gravitational microlensing can complement other exoplanet
detection techniques
like radial velocity and the transit method, which are limited in discovering mostly massive
planets in relatively close orbits around their host stars.
Detection of Jupiter's twin orbiting a distant Sun -
like star represents the closest replication of our own solar system to date, and may have profound implications for creating conditions favorable to the development of a habitable Earth -
like planet in HIP 11915's inner solar system.
