Old data for @planetarysociety.bsky.social's LightSail 2 mission The sail angled face-on to catch sunlight & maximize thrust when moving away from the Sun in LEO, and then rotated edge-on, or "feathered," to minimize opposing solar pressure and atmospheric drag when moving toward it.

Project Moonwatch made a human “meridian fence”: observers aimed small telescopes at different slices of a precisely known north–south line & timed satellite crossings. The crossing time fixed right ascension, the telescope angle gave declination, and later sightings yielded an orbit.

…So, in roughly 4¾ hours of simultaneous observing, they could collect approximately as many photons as one Seestar operating for 246 hours. The combined image has about 7.2 times better signal-to-noise than one telescope observing for the same 4¾-hour period.

The country’s latest mission, Chang’e 7, will be the first ever to land directly at the moon’s south pole. Whatever it finds there could radically reshape a new space race

Ask Ethan: Should we stop worrying about vacuum decay?
Vacuum decay is one of the most frightening, and undetectable-until-it-happens, possibilities for how this will all end.
But if we learn enough, there could be a way to stop it.

Our Universe has a positive, non-zero value to the energy within empty space. Can we potentially save ourselves by considering vacuum decay?

Interesting conservatory communication across time from curator to curator. Goal is to leave a trail for those who come after. Every treatment documented so future conservators can distinguish original material from later intervention, reverse today’s decisions if better techniques emerge.

99% of a core-collapse supernova’s energy is invisible
Despite how luminous core-collapse supernovae are, 99% of the energy they carry away is invisible: in the form of neutrinos.
Here's why that must be the case.
