outstanding_bond, w NASA Selects a Wild Plan to "Swarm" Proxima Centauri With Thousands of Tiny Probes

A very cool idea, however the headline is misleading - NASA has not even remotely committed to running this mission. They’ve selected the swarm project as one of 13 projects in their innovation program and given it up to $175k to study feasibility. That’s roughly a postdoc for two years. This is far, far from committing the hundreds of millions or billions needed for the execution of this mission.

Paragone, w Curiosity Mars rover discovers largest organic molecules ever seen on Red Planet

Alkanes, from the possible breakdown of fatty-acids, in distant past…

but without knowing the answer to that question…

it isn’t decided, is it?

Man I need to get my scope out again. It’s been years. Maybe one of these days…

threelonmusketeers, w Asteroid 2024 YR4 now has a 1.94% chance to hit the Moon (according to my own calculations)

Do we know if the Moon will be in the correct phase in it’s orbit when 2024 YR4 comes by? I didn’t notice a term to account for that, but I’m not too familiar with Desmos.

LostXOR,

The calculations for the close approach data I'm using to calculate the probability already take the Moon's orbit into account.

I’d love to have been in the room when Galileo sent back its first images of Io back in the day. The collective “wtf am I looking at?” reaction would be priceless.

Not with a bang, but a whimper.

acockworkorange, w Astronomers 'looked back in time' and found a double jet shooting from a black hole, twice the width of our Galaxy
