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 #ESAEuclid mission, the #Euclid 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 #ESAEuclid coming Thursday, 23 May. Five new stunning images, first ten science papers plus five #Euclid reference publications.
There will be broadcast by #ESA as well as press and paper releases by ESA and us. Stay tuned!
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.
Looking towards the southern constellation of Circinus, NGC 5315 appears, a planetary nebula located at a distance of about 8,000 light years from the Solar System. It is located 5.2 degrees west-southwest of Alpha Circini. Although its progenitor star called HD 120800 shines with a magnitude of 14, the nebula has an apparent magnitude of 9.8, much..... #astronomy#space#astrophysics#astrophotography
“We’ve talked in the past about there being academic evidence, engineering studies. What we are actually seeing now with those satellites in operation is empirical evidence. You see the noise floor on our satellites increase to the degree that services cannot be provided.”
"This work presents a photometric model of the Starlink satellites based on the Bidirectional Reflectance Distribution Function (BRDF) using millions of photometric observations. ... In addition to assessing the light pollution and guiding the development of response measures, accurate photometric models of satellites can also play an important role in areas such as space situational awareness."
