Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds... Hebrews 1:2
"Astronomers Discover Smallest Free-Floating Exoplanet Yet......
The newly-detected microlensing event, designated OGLE-2016-BLG-1928, lasted only 41.5 minutes.
“When we first spotted this event, it was clear that it must have been caused by an extremely tiny object,” said co-author Dr. Radoslaw Poleski, an astronomer with the Astronomical Observatory at the University of Warsaw.“Indeed, models of the event indicate that the lens must have been less massive than Earth, it was probably a Mars-mass object. Moreover, the lens is likely a rogue planet.”
“The discovery of OGLE-2016-BLG-1928 demonstrates that current microlensing surveys are capable of finding extremely-short-timescale events,” the researchers said.
“Although the mass of the lens cannot be unambiguously measured, properties of the event are consistent with the lens being a sub-Earth-mass object with no stellar companion up to the projected distance of 8 AU (astronomical units) from the planet.”
