Meet ploonets: planets of moonish origin.
In other star systems, some moons could escape their planets and start orbiting their stars instead, new simulations suggest. Scientists have dubbed such liberated worlds “ploonets,” and say that current telescopes may be able to find the wayward objects.
Astronomers think that exomoons — moons orbiting planets that orbit stars other than...
There’s another oddly flickering star in the galaxy.
Astronomers using a telescope in Chile have discovered a star whose strange dimming and brightening of light are reminiscent of Tabby’s star, which was once suggested to host an alien megastructure.
The megastructure idea, first posited in 2015, was later quashed by data suggesting that the dips are probably from dust particles...
