Mercury’s transit today
Here are a few links on today’s transit of the Sun by Mercury, which is going on right now.
I could give more, but this event is hardly as important as many new media are saying. It is interesting, and rare, and important in that it helps scientists get a better understanding of the uncertainties in their exoplanet research, but hardly important scientifically.
Consider this however: Mercury’s real orbit has it circle the sun every 88 days. If we could only detect it by the transits seen from Earth, we would only see it cross the Sun in 2006, 2016, 2019, and 2032. Figuring out its real orbit from that data would likely be impossible. Now, I realize that these seemingly random transits are partly determined by the Earth’s own orbit around the Sun, but they still illustrate that our use of transits to detect and characterize exoplanets has its limits. And in science one must always be aware of one’s limits.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

“And in science one must always be aware of one’s limits.”
I hadn’t known that ‘Dirty’ Harry Callahan was a scientist.
Having never seen the Dirty Harry films, I am unaware of the reference. Was I unconsciously quoting him?
“A man’s got know his limitations.”
‘Magnum Force’
1973
