They almost definitely can't see us. It's 1470 light years away, the light they are seeing now left earth in 650 AD, there wouldn't be much to see, at least ass

They almost definitely can't see us. It's 1470 light years away, the light they are seeing now left earth in 650 AD, there wouldn't be much to see, at least assuming the presumed ETs can detect EM transmissions and analyze the earths atmosphere but not directly observe the surface with any appreciable resolution.
- jcims 5y agoThe underlying theory behind the SETI interest is that we are seeing the effects of 'alien megastructures' in orbit around that star. If they can build that, presumably they would be able to build scientific instrumentation to characterize the planet if not directly image it.
- hungryforcodes 5y agoI think his point is more that -- given the speed of light -- it's extremely unlikely that there is anything to see from us in...650AD which is what would be arriving there right now.
