Why is the us department of energy building telescopes? Did I misunderstand something?


They're involved, and they're building orbital sensors, and they are the OG discovers of really big gamma ray bursts.

Why?

Well the Departamento de Energía de Estados Unidos (DOE) (as the article refers to them) is interested in "energy" .. and by "energy" they really mean nuclear weapons.

It was a Cold War thing.

Their interest here is in ground truthing and the elimination of "normal, not a bomb" stuff ... it'd be a bad day if an astro event billions of years in the past triggered a global thermal nuclear war because Bob the nanosecond reflex triggerhappy automaton got confused about a couple of rapidly spinning galactic core black holes eating each out.

Or, as the DOE explains:

https://www.energy.gov/science/doe-explainsdark-matter

err, or rather 'explains' but doesn't mention much about the intial rational behind their decades of work with orbiting gamma ray sensors.

Nothing to see here.


Yes, the first astronomical gamma ray bursts showed up as events on Vela nuclear explosion detection satellites in the late 60s: https://en.wikipedia.org/wiki/History_of_gamma-ray_burst_res...


They need to understand high-energy physics, and most of the places to study them are in the sky.


Dark Energy primarily, dark matter to a lesser degree. The other reason is because NSF doesn’t really “run“ things.

Are they sure those are not chinese spy baloons ? You can't be paranoid enough when it comes to "national security" /s
