• Help identifying flashing stationary object at night.

  You could download Stellarium. It's free. There's a satellite feature in there which allows you to see which satellites are above you. As to different intensities of the flashing, this is typical, as the angle of reflection of the sunlight from the satellite isn't always the same. And these aren't disco satellites, although there are a couple in orbit with reflective panels completely surrounding them. These are... - Source: Reddit / 3 days ago

  Pluto is, depending on where it is in its orbit ~30-50 au from earth, so the speed of light time is ~4-7 hours. (Stellarium says that it's currently ~4 hours, 47 minutes). This is of course, ignoring that we're not going to find life on the surface and that there was a spacecraft flyby of it in 2015. Which leads me to the question: were you thinking of an exoplanet? - Source: Reddit / 27 days ago
