An exomoon or extrasolar moon is a natural satellite that orbits an exoplanet or other non-stellar extrasolar body. [2] Exomoons are difficult to detect and confirm using current techniques, [3] and to date there have been no confirmed exomoon detections. [4] .

2024年10月14日 · We’ve got a cosmic mystery on our hands. No one’s ever confirmed the existence of an ‘exomoon,’ which is a moon outside our solar system. However, a new NASA-led study might finally give us some indirect evidence for one in …

2024年10月17日 · NASA scientists have uncovered new evidence of a hellish, volcanic "exomoon" orbiting a superheated alien world relatively close to Earth. The proposed satellite, which may be covered with lava,...

2018年10月3日 · NASA’s Hubble and Kepler space telescopes have uncovered what could be the first exomoon. Based upon their findings, the team spent 40 hours making observations with Hubble to study the planet intensively – also using the transit method – obtaining more precise data on the dips of light.

2022年7月17日 · Exomoons are moons that orbit exoplanets, planets that orbit stars other than the sun. To date, no exomoons have been confirmed, yet that will likely change.

October 2018 — researchers using the Hubble Space Telescope published observations of the candidate exomoon Kepler-1625b I, which suggest that the host planet is likely several Jupiter masses, while the exomoon may have a mass and radius similar to Neptune.

2024年1月30日 · Scientists doubt proposed detection of the 1st exomoons. These two moons were like nothing found in the solar system. They both exhibited sizes greater than Earth's, for instance, which made them...

2017年7月28日 · The first evidence for an exomoon — a moon orbiting a planet orbiting a distant star — may have been spotted in data from the Kepler space telescope. But surprisingly, exomoons in general may...

2024年10月25日 · Currently, there are no confirmed exomoons, only a list of candidates, some of which should be in habitable zones if they're real. Kipping and his team have succeeded in getting some JWST...

2022年4月13日 · The Discovery: An international team of astronomers confirms 60 new exoplanets, or planets orbiting other stars; a separate study finds tentative evidence of an “exomoon.” Key facts: Data from NASA’s now-retired Kepler Space Telescope reveals an eclectic assortment of new planets and planetary systems that promises to deepen understanding ...
