Exoplanet Explorers
Exoplanet Explorers was a Zooniverse citizen science project aimed at discovering new exoplanets with Kepler data from the K2 mission. The project was launched in April 2017 and reached 26,281 registered volunteers. Two campaigns took place, the first one containing 148,061 images and the second one 56,794 images. A total of 9 exoplanets were found through the project: K2-138 b, c, d, e, f and g (initially referred to as EE-1b, EE-1c, EE-1d, and EE-1e), K2-233 b, c, and d, and K2-288Bb K2-288Bb (previously designated EPIC 210693462 b) is a super-Earth or mini-Neptune exoplanet orbiting in the habitable zone of K2-288B, a low-mass Red dwarf, M-dwarf star in a binary star system in the constellation of Taurus (constellation), Tau .... K2-288Bb is considered to be potentially habitable with a radius of 1.91 Earth radii and a temperature of 206 K. Several other candidates in size groups were also found: Jupiters: 44, Neptunes: 72, super-Earths: 53, Earths: 15. See also * Pla ...

Planetary Transit
In astronomy, a transit (or astronomical transit) is the passage of a celestial body directly between a larger body and the observer. As viewed from a particular vantage point, the transiting body appears to move across the face of the larger body, covering a small portion of it. The word "transit" refers to cases where the nearer object appears smaller than the more distant object. Cases where the nearer object appears larger and completely hides the more distant object are known as ''occultations''. However, the probability of seeing a transiting planet is low because it is dependent on the alignment of the three objects in a nearly perfectly straight line. Many parameters of a planet and its parent star can be determined based on the transit. In the Solar System One type of transit involves the motion of a planet between a terrestrial observer and the Sun. This can happen only with inferior planets, namely Mercury and Venus (see transit of Mercury and transit of Ve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zooniverse
Zooniverse is a citizen science web portal owned and operated by the Citizen Science Alliance. It is home to some of the Internet's largest, most popular and most successful Citizen science, citizen science projects. The organization grew from the original Galaxy Zoo project and now hosts dozens of projects which allow volunteers to participate in crowdsourced scientific research. It has headquarters at Oxford University and the Adler Planetarium. Unlike many early internet-based citizen science projects (such as SETI@home) which used spare computer processing power to analyse data, known as volunteer computing, Zooniverse projects require the active participation of human volunteers to complete research tasks. Projects have been drawn from disciplines including astronomy, ecology, cell biology, humanities, and climate science. , the Zooniverse community consisted of more than 1 million registered volunteers. By March 2019, that number had reportedly risen to 1.6 million. The v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kepler Space Telescope
The Kepler space telescope is a defunct space telescope launched by NASA in 2009 to discover Earth-sized planets orbiting other stars. Named after astronomer Johannes Kepler, the spacecraft was launched into an Earth-trailing heliocentric orbit. The principal investigator was William J. Borucki. After nine and a half years of operation, the telescope's reaction control system fuel was depleted, and NASA announced its retirement on October 30, 2018. Designed to survey a portion of Earth's region of the Milky Way to discover Earth-size exoplanets in or near habitable zones and to estimate how many of the billions of stars in the Milky Way have such planets, Kepler's sole scientific instrument is a photometer that continually monitored the brightness of approximately 150,000 main sequence stars in a fixed field of view. These data were transmitted to Earth, then analyzed to detect periodic dimming caused by exoplanets that cross in front of their host star. Only planets whos ...

K2-138
K2-138, also designated EPIC 245950175 or EE-1, is a large early K-type main sequence star with a system of at least 6 planets discovered by citizen scientists. Four were found in the first two days of the Exoplanet Explorers project on Zooniverse in early April 2017, while two more were revealed in further analysis. The system is about away in the constellation Aquarius (constellation), Aquarius, within Kepler space telescope#Second Light (K2), K2 Campaign 12. Planetary system K2-138 is notable for its large number of planets, all found through the efforts of citizen scientists. They are designated K2-138b, c, d, e, f, and g in order from their host star. The first five were validated by Christiansen et al., while K2-138g was noted as being a likely candidate. However, since there were only two transits of it, K2-138g could not be validated. There was a possibility that the two transits for this candidate were from two individual long-period planets. K2-138g was confirm ...

K2-288Bb
K2-288Bb (previously designated EPIC 210693462 b) is a super-Earth or mini-Neptune exoplanet orbiting in the habitable zone of K2-288B, a low-mass Red dwarf, M-dwarf star in a binary star system in the constellation of Taurus (constellation), Taurus about 226 light-years from Earth. It was discovered by Methods of detecting exoplanets#Amateur discoveries, citizen scientists while analysing data from the Kepler space telescope's K2 mission, and was announced on 7 January 2019. K2-288 is the third transiting planet system identified by the Exoplanet Explorers program, after the six planets of K2-138 and the three planets of K2-233. K2-288Bb is likely to be in the habitable zone of its host star, and thus may be capable of supporting life, though the planet's composition is unknown. Discovery K2-288 was observed by the Kepler space telescope during Campaign 4 of its extended K2 "Second Light" mission, lasting from April through September 2015. A group of astronomers looked through t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planet Hunters
Planet Hunters is a citizen science project to find exoplanets using human eyes. It does this by having users analyze data from the NASA Kepler space telescope and the NASA Transiting Exoplanet Survey Satellite. It was launched by a team led by Debra Fischer at Yale University, as part of the Zooniverse project. History Planet Hunters and Planet Hunters 2.0 The project was launched on December 16, 2010, after the first Data Release of Kepler data as the Planet Hunters Project. 300,000 volunteers participated in the project and the project team published 8 scientific papers. On December 14, 2014, the project was re-launched as Planet Hunters 2.0, with an improved website and considering that the volunteers will look at K2 data. As of November 2018 Planet Hunters had identified 50% of the known planets with an orbital period larger than two years. Non-Planet Hunters project: Exoplanet Explorers In 2017 the project Exoplanet Explorers was launched. It was another planet hun ...

Planet Patrol (project)
Planet Patrol is a NASA citizen science project available in Zooniverse and aimed at discovering new exoplanets with data from the Transiting Exoplanet Survey Satellite, TESS telescope. The project is built on results produced by a computer algorithm. The algorithm measures the center-of-light of the images and automatically compares it to the catalog position of the corresponding star. The main difference with Planet Hunters is that Planet Patrol looks at objects that represent a detected planet candidate in TESS data, whereas Planet Hunters searches through all the stars in the TESS databases and asks humans to find such candidates. As of September 2020, there are 1370 volunteers and 72,938 classifications have been done. The images representing a possible exoplanet transit show a single bright source near the middle of the image with a dot at the center. Results Two papers were published by Planet Patrol, vetting 1998 TESS Objects of Interest (TOIs). Of these TOIs 1461 pas ...
