The nearest star other than sun, Proxima Centauri is 4.2 light years aways from us.
The sun itself is about 8 light minutes away from us.
It takes 4.5 hrs for a signal to reach from New Horizon which fled past Pluto.
Like every ootherthing, light does have speed limit which on general notion is taken to be 299,792,458m/s.
Being 1400 light years away from us means we are actually looking at the past of the planet.
Since we can see this planet,there can also be a possibility of intelligent life residing there watching us.
But if they could see us,then probably they would be seeing Chandragupta's dynasty ruling over Indian subcontinent.
Now if some comet hits us today and earth vanishes, this intelligent life will come to know it 1400 years later.
Since Light again will take that many years of time to reach there.
So,if this planet recently discovered is already destroyed,then we will get to know it after 1400 years.
