The various detection techniques such as radial velocities, transit, microlensing, direct imaging, timing or astrometry, provided thousands of planet detections.

Microlensing is an indirect planet detection method since we are not measuring the planet itself, but rather the planet's effect on another object.

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

Once the OGLE team realized this would be a planet detection, they contacted the Microlensing Follow Up Network, microFUN, to see if someone could continue the observations and detect the planet again while it was daytime at Las Campanas, and therefore unobservable.

Their hope is to produce a library of potential planetary climates in the Universe, which can then be used for research on habitability and planet detection.

If confirmed by other researchers, the planet would not just be an astronomical novelty; Its detection, reported on the e-print server at the Los Alamos National Laboratory (see astro - ph / 9908038), would also be a triumph for a new and potentially powerful technique for finding planets around other stars.

One recent detection is telling: A planet orbiting a roughly 5 - billion - year - old M dwarf, named Gliese 1132, appears to have an atmosphere that might contain either water vapor or methane, John Southworth, an astrophysicist at Keele University in England, and colleagues reported in the April Astronomical Journal.

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.

[6] This detection rate of 3 planets in a sample of 88 stars in Messier 67 is close to the average frequency of planets around stars that are not members of clusters.

Meanwhile, detections of extrasolar planets prove that planets form in such disks — and often.

Imaging detections are challenging because of the combined effect of small angular separation and large luminosity contrast between a planet and its host star.

That's why the Pale Red Dot project, tasked with finding a planet around our nearest neighbor, had to turn to indirect — but reliable — methods of detection.

That detection was riddled with problems, drawn out from spurious data, and ignored a low signal - to - noise ratio in search of a sensational new planet, the kind science fiction has long dreamed of.

Part of the caginess may arise from a 2012 detection of a planet around another star in the system, Alpha Centauri B.

Nobody has ever conclusively seen a moon orbiting a planet in another stellar system, partly because their small size and great distance makes them difficult to find with modern detection methods.

At the moment, most planets are discovered when we see their shadows dance in front of their host star — a technique that limits detections because it requires the planet to pass through the exact line of sight between its star and Earth.

Marois and his team used ground - based infrared detection to seek out exoplanets around nearby, young, massive stars — those whose planets would have wide orbits and emit significant amounts of radiation as they cool from their relatively recent births millions of years ago.

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.
