Exoplanet Discoveries and Updates
Coherent low-frequency radio emission was detected on the quiescent M4.5 star GJ 1151. I don't know the exact details nor how it actually works, but it is analogous to the interactions between Jupiter's magnetosphere and its moons. Therefore, some researchers suggested that this may be evidence of an orbiting planet.

Details about this world are almost nonexistent right now, but we do know that
- Its orbital period is somewhere between 1-5 days
- Its minimum mass is no more massive than 5.6 Earth masses

Next, scientists are trying to confirm the planet through radial velocity, which should give us much more precise values for the orbital period and minimum mass.
