The atmosphere of TOI 5205b has a lower concentration of heavy elements relative to hydrogen than gas giants in our own solar system, suggesting something different about its formation.

Orion is hurtling toward where the Moon will be, not where it is-like a quarterback leading his receiver-they've already got a slightly different angle on the Moon than we do here on Earth.

The proposed scale of orbital deployment would represent a significant alteration of the natural night-time light environment at a planetary scale.

In the silent vacuum of space, five autonomous robots churn through the lunar surface, digging up a loose layer of rock and dust and leaving rows of uniform tracks in their wake. Stopping only to recharge at a central solar power station, the car-sized machines process the lunar dirt internally to extract a type of helium so rare on Earth that a palm-sized container is estimated to be worth millions.
