I can tell if it's a clear night by smell. Can anybody explain this?

So for some reason, when I go out at night (anywhere, not just when I observe) I can tell if it's a clear night or not just by the smell. How does this even work? I tried it multiple times and thus far it has worked all the time. I could do the same at any other location, and I found nobody else who could do this. If somebody could help it would be appreciated.

Emre Kelly on Twitter: At a Space Mobility panel in Orlando, KSC director Janet Petro says Air Liquide, which supplies KSC with nitrogen, was nervous about supporting January's Falcon Heavy/USSF-67 on the heels of Artemis. SpaceX came up with a unique solution by bringing in nitrogen "rechargers."

If photons don’t have mass, then why are they affected by gravity?

So I just saw a post on this sun that talked about the theory of, the oldest information in the universe being unreachable because the universe is ever expanding. Also that the infrared light wouldn’t reach to the edges of our universe for us to be able to see that information This got me thinking about the properties of light. It made me wonder if light itself could bend around planets since even light can’t escape black holes. I then began to wonder that gravity itself has another property we don’t understand. *why would gravity affect light if light A:(has no mass), and B:(is not matter)* This would mean that there would have to be a shared property or two properties(one from gravity, and another from light) that directly Influences eachother…? Would we even be able to tell if space was bending right before our eyes?

#OTD in 1969, the Soviet Union launched the first test flight of its giant N-1 rocket. The test failed, as did the three that followed. A model of the N-1 rocket and a model of the Saturn V rocket (both pictured here) is in our collection. https://t.co/Ns8jQttiH1

Is there a reason why the periods of the axial precession and nodal precession of Luna are the same?

As I was reading [this](https://en.wikipedia.org/wiki/Lunar_precession) I noticed that these two periods (axial and nodal precession) are the exact same, at ~18.6 years. Is there a reason for this, as there is for e.g. tidal locking, or is it considered to be a "coincidence" (for now)?
