Phosphine detected on Venus

Recommended Posts

I wouldn't get too excited about marginal instrument readings from a distant planet such as Venus.

This has happened before, in the case of the similarly distant planet Mars.  You know what I mean - the "canals".

The canals were debunked well over a hundred years ago. The sightings involved no instrument readings, just antique telescopes with no photography.

You should study up, they've stopped using orreries at NASA.

I'm pretty sure that a telescope is an instrument.

The point is that, at the time people were drawing pictures of "canals on Mars", they were struggling against the resolution of their telescopes.
Now they are struggling against the resolution of their spectroscopes.

Steam engines were invented at steam engine time.

Up until relatively recently, millimeter wave spectroscopy was so impractical that nobody did it.
The technology has changed but it's still not a mature technology. A bit like the old telescopes.


It's a valid comparison.
