Re-entries: anytime, anywhere!

Since militaries are the prime customer, probably: all the time, and everywhere.

1112 authors for a space mission 🛰️ reference paper seems ... adequate 🤷🏽😯😁

We, the @ec_euclid will publish five main reference papers aimed at the astronomy community about the mission, the instruments, both cosmology and other astronomy science possibilities, as well as the cosmological simulations used to test all procedures.

Available coming Tuesday, 23 May, 12:00 CEST (and on arXiv a few hours later). Stay tuned!

Expect new images and first science results from coming Thursday, 23 May. Five new stunning images, first ten science papers plus five reference publications.

There will be broadcast by as well as press and paper releases by ESA and us. Stay tuned!

The Pentagon is rushing to expand its capacity to wage war in space, convinced that rapid advances by China and Russia in space-based operations pose a growing threat to U.S. troops and other military assets on the ground and U.S. satellites in orbit. https://www.japantimes.co.jp/news/2024/05/18/world/new-star-wars-plan-space-threats-us/ #worldnews #us #usmilitary #defense #missiles #space #nuclearweapons #china #russia

Sun and moon combo: I finally got some OK skies overnight last night and few enough clouds to shoot through during the day today to get another moon/sun combo. These images were captured a little over 9 hours apart.

A mind-blower for a Friday evening:

This deceptively simple-looking graph is a spectrum of gravitational waves ringing through the Milky Way.

The waves may be caused by a chorus of supermassive black holes colliding all across the universe. Whoa!
