Neither study finds fault with the other's analysis, Teachey added;
Hubble observed a transit in October 2017-
one that included two substantial anomalies, Teachey and Kipping said.
Therefore, at this point the moon signal has been both validated and
called into question by other teams," Teachey said.
Indeed, Teachey and Kipping described the newly detected object,
known as Kepler-1625b I, as a candidate rather than the first confirmed exomoon.
In the coming days, Teachey said, the pair plans to submit a paper that,
among other things, analyzes the work done by Kreidberg and her colleagues.
Like Teachey and Kipping, the teams led by Kreidberg and Heller detected"transit-timing variations"-
signs that something other than the host star may be tugging on Kepler-1625b gravitationally.
