Having taken an astronomy course, the best response would be:
It is probably a hole in the universe; if I read it on the internet, they must have already verified it.
Olt is probably a cosmic void; let's investigate it in radio or microwave wavelengths to verify.
It is probably a black hole: let's investigate it in x-ray wavelengths to verify.
It could be anything: astronomers have not yet figured out how to investigate such mysterious objects.
It is probably a dark (absorption) nebula: let's investigate it in infrared wavelengths to verify
