JWST Reveals Bizarre Carbon-Rich Atmosphere on Black Widow Pulsar Planet

Explore the highly mysterious planet recently analyzed by JWST, which sports an atmosphere overwhelmingly rich in carbon, challenging current planetary formation models. Learn how this object, orbiting a pulsar, exhibits unique wind patterns never before confirmed.

Short Summary

  • The James Webb Space Telescope (JWST) detected atmospheric C2 and C3 molecular dominance, indicating extreme carbon saturation.
  • Strong, observationally confirmed westward winds challenge previous predictions for atmospheric circulation on tidally locked worlds.
  • The findings create a new puzzle regarding how the companion star formed and survived the intense stripping process.

This discussion breaks down the recent JWST observations of PSR J2322650, a planet orbiting a pulsar within a Black Widow system. The findings indicate an atmosphere dominated by molecular carbon species, alongside the first observational evidence of westward atmospheric circulation on such a world, forcing scientists to develop new models for companion stars subjected to intense radiation.

Can you imagine being next to that Carbon gas giant orbiting a neutron star? Seems like a science fiction premise but it's actually out there. This is why I love space science

Very informative video. My amateur hypothesis: The original star had just gotten to the stage where it was burning some helium into carbon. The neighbor star went supernova, stripped all the lighter materials away, and became a pulsar. Thus, only the carbon core remained. It was originally compressed into something similar to graphite, but the loss of the pressure from losing the surrounding hydrogen and helium made it expand into different carbon gases - after the blast of the supernova was already over. Over time, the few heavier atoms could sink to the core, while any lighter elements would still evaporate into space. Also, as a pulsar produces no real amounts of solar wind, and even less of that as hydrogen or helium, those could not be replenished.

Every day, a new clue arrives to remind us how clueless about the Universe we are

We can analyze the wind direction of an exoplanet. Let that sink in.

It’s totally amazing how much we can tell about exoplanets, not that long after discovering exoplanets exist at all! Another superb episode, Anton!

Saw someone in the comments say that they watch your videos every day. I don't think I've missed more than 5% of them over the past few years. My favorite channel on YouTube. Never stop, Anton!
