NASA’s Webb Delivers Deepest Infrared Image of Universe Yet

NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.

Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.

The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions, as Webb seeks the earliest galaxies in the universe.

It wasn’t just that they didn’t want to smell the infected and dead, they thought it was crucial to protecting themselves. They had no way of knowing about what actually caused the plague, and so one of the other theories was that the smell of the infected all by itself was evil and could transmit the plague. So not only would they fill their masks with aromatic herbs and flowers, they would also burn fires in public areas, so that the smell of the smoke would “clear the air”. This all related to the miasma theory of contagion, which was one of the major theories out there until the 19th century. And it makes sense, in a way. Plague victims smelled awful, and there’s a general correlation between horrible septic smells and getting horribly sick if you’re around what causes them for too long.

You can see now that we’ve got two different theories as to what caused the plague that were worked into the design. That’s because the whole thing was an attempt by the doctors to cover as many bases as they could think of, and we’re still not done.

The glass eyepieces. They were either darkened or red, not something you generally want to have to contend with when examining patients. But the plague might be spread by eye contact via the evil eye, so best to ward that off too.

The illustration shows a doctor holding a stick. This was an examination tool, that helped the doctors keep some distance between themselves and the infected. They already had gloves on, but the extra level of separation was apparently deemed necessary. You could even take a pulse with it. Or keep people the fuck away from you, which was apparently a documented use.

Finally, the robe. It’s not just to look fancy, the cloth was waxed, as were all of the rest of their clothes. What’s one of the properties of wax? Water-based fluids aren’t absorbed by it. This was the closest you could get to a sterile, fully protecting garment back then. Because at least one person along the line was smart enough to think “Gee, I’d really rather not have the stuff coming out of those weeping sores anywhere on my person”.

So between all of these there’s a real sense that a lot of real thought was put into making sure the doctors were protected, even if they couldn’t exactly be sure from what. They worked with what information they had. And frankly, it’s a great design given what was available! You limit exposure to aspirated liquids, limit exposure to contaminated liquids already present, you limit contact with the infected. You also don’t give fleas any really good place to hop onto. That’s actually useful.

Beyond that, there were contracts the doctors would sign before they even got near a patient. They were to be under quarantine themselves, they wouldn’t treat patients without a custodian monitoring them and helping when something had to be physically contacted, and they would not treat non-plague patients for the duration. There was an actual system in place by the time the plague doctors really became a thing to make sure they didn’t infect anyone either.

I love the stick, too. There are contemporary drawings of doctors examining patients through windows. They wouldn’t even go into houses after a point. And sometimes the houses were quarantined, so families were trapped inside with plague victims.

So that kicked off another round of Everybody Blame The Jews For Things Wot They Did Not Do.

But here’s another, even more counterproductive theory on the origins of the plague, circa plague-having times: God was angry because the church had failed him. You still hear that all the time from certain sects, so what’s the difference with this time? Well, first of all, the corrupt priests were sort of the only ones who weren’t dying. Priests were supposed to give last rites to their parishioners, and those that really did try to give them to everyone, whelp, they caught the plague. And the last rites are a big deal because anointing the sick is one of the seven sacraments everyone is supposed to get and priests are required to do. The guys who didn’t, though, were the ones who didn’t give a shit about what was commonly believed to be the way you made sure everyone didn’t literally go to hell. So, people who were looking for someone to blame suddenly had a fairly solid wall of bastards to point at as the problem.

So, what did they do about it? Well, among other things, they decided that if god was angry and the priests weren’t cutting it, they’d perform penance themselves to show their faith and lift the plague! …So they formed roving bands of flagellants who spread the plague!

The peak of the activity was during the Black Death, then called the Great Death, which began around 1347. Spontaneously Flagellant groups arose across Northern and Central Europe in 1349, except in England. The German and Low Countries movement, the Brothers of the Cross, is particularly well documented - they wore white robes and marched across Germany in 33.5 day campaigns (each day referred to a year of Jesus’s earthly life) of penance, only stopping in any one place for no more than a day. They established their camps in fields near towns and held their rituals twice a day. The ritual began with the reading of a letter, claimed to have been delivered by an angel and justifying the Flagellants’ activities. Next the followers would fall to their knees and scourge themselves, gesturing with their free hands to indicate their sin and striking themselves rhythmically to songs, known as Geisslerlieder, until blood flowed. Sometimes the blood was soaked up in rags and treated as a holy relic.

Originally members were required to receive permission to join from their spouses and to prove that they could pay for their food. However, some towns began to notice that sometimes Flagellants brought plague to towns where it had not yet surfaced. Therefore later they were denied entry. They responded with increased physical penance.

Fortunately, this all happened long enough ago that I can feel safe about giggling helplessly at that last bit there.
