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."
I'm more of a reader than a writer in 'Mastodon Space' but today I bring you something that those people I follow may not have heard of: what's likely to be the first attempt at a space suit, designed as early as 1936 in Spain. It was to be tested with a hot air balloon but unfortunately the whole thing had to be scrapped due to the Civil War. One piece of the original suit has now been found. In Spanish but Google Translate does the trick.
