Kepler-1625b I is a possible moon of exoplanet Kepler-1625b, which may be the first exomoon ever discovered (pending confirmation), and was first indicated after preliminary observations by the Kepler Space Telescope. [4]
In July 2017, researchers found signs of a Neptune-sized exomoon (a moon in another solar system) orbiting Kepler-1625b using archival Kepler Mission data. [ 5 ] [ 6 ] In October 2018, researchers using the Hubble Space Telescope published new observations of the star Kepler-1625 which revealed two independent lines of evidence indicative of a ...
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. The study concluded that the exomoon hypothesis is the simplest and best explanation ...
Artist's impression of candidate exomoon Kepler-1625b I orbiting its planet. [1] 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]

Kepler-1625 is an approximately solar-mass star and yet is 1.7 times larger in diameter. [3] Its effective temperature is around 5,550 K, slightly lower than that of the Sun. [12] [3] These parameters suggest that Kepler-1625 may be a yellow subgiant nearing the end of its life, with an age of approximately 8.7 billion years. [3]
The study, published June 6 in the journal Physical Review Letters, reveals that these black holes must have appeared in the first quintillionth of a second of the big bang: “That is really ...
Archaeologists believe they may have discovered the final location of Noah’s Ark on Turkey’s Mount Ararat. Soil samples from atop the highest peaks in Turkey reveal human activity and marine ...
