Last year, data from the James Webb Space Telescope soured hopes that TRAPPIST-1 c had an atmosphere that could support life. But recent results have revived those earlier atmospheric hopes. Read more from Big Think. https://flip.it/ClyATt

#UMPlus - Solar flare X3.9

https://www.universomagico.net/2024/05/erupcion-solar-x39.html

The Sun emitted a strong solar flare, which peaked at 6:54 am UT on May 10, 2024. The Solar Dynamics Observatory, which observes the Sun constantly, captured an image of this event, as seen in the bright flash towards the center of the image. Solar flares are powerful explosions of energy that can affect radio communications, electrical power grids, navigation signals and.....

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.
