I don’t think I should be the one to decide what the night sky will look like for the entire world. And I don’t think Musk should be either. Or a committee from the AAS. I think this should be a global conversation that includes many, many more voices.

@BadAstronomer  There are already international agreements/treaties in place about the use of Antarctica for research, the Moon, space in general. Agreements about how people can alter our night sky could follow similar trajectories.

ME: *minding my own business, working on some stuff, having a normal evening* MY BODY: How about: hiccups?

I’m going to have to delete this tweet to save my mentions from advice aren’t I

Quick addendum to this: there have always been, and always will be, scientists who act in dishonest and/or unethical ways. Because they are humans. That’s WHY the scientific process of discussion and peer review and the whole community exists, and that’s why consensus matters.

The whole point of the process is to save us from ourselves by throwing us at each other. Every scientist wants to be right & have a breakthrough. That causes bias. So we have incentives to say “maybe your breakthrough isn’t real; that’s MY breakthrough!” Ideally it balances out

HnxTvaDYhwUpshot: This doesn't appear to be a settled question at all. (More research needed!)

@warden_dios_57  It's difficult to say that *anything* is safe or not safe -- the research is not always very clear. There doesn't appear to be any reason to be alarmed about aluminum right now; from what I can find, it's likely as safe as anything else you might cook with.


If someone's political stance requires preventing scientists from informing you about your own planet, that's not politics, it's oppression.

Retweet if it's by absolute sheer meaningless luck that you weren't born in Syria with bombs falling all around you, desperate for refuge.

First ever direct image of a black hole! The supermassive black hole in the galaxy M87 -- 6.5 billion times as massive as the Sun! #EHT  #BlackHole  The image is better than I expected!

Any president who would prefer civil war to being removed from office does not love their country and is certainly not serving it

Please do not fall prey to the idea that any activity that does not measurably advance your career is somehow necessarily harming it. You have only this one beautiful life; do not avoid living it for fear that your total productive output might be less than the theoretical max.

Scientific evidence suggests human-caused climate change is making extreme weather events more common. This is not a political statement.

So, hypothetically… if you control every branch of power, kill a couple popular programs for no reason, then try unsuccessfully to use them as leverage & end up shutting down your own government… maybe you are bad at governing & shouldn’t.

Stating scientific facts about the atmosphere of our planet is not and must not be "politics." Reality should not be a political stance.

Kind of astonishing to see both the US and UK governments light their own houses on fire based on some vague paranoid fear that someone else might want to come in
