#UMPlus - Messier 61 Through the Spectrum

https://www.universomagico.net/2025/04/messier-61-traves-del-espectro.html

Magical Universe's approach to displaying the galaxy Messier 61 is a double slow transition, allowing the galaxy's distinct details to be appreciated by changing the wavelengths of the electromagnetic spectrum with each observation. Messier 61, also cataloged as NGC 4303 among other designations, is.....

The same dirt that clings to astronauts' boots may one day keep their lights on. In a study published in Device, researchers created solar cells made out of simulated moon dust. The cells convert sunlight ...

Paper day for least-model-dependent astrophysics! On today's menu: an old-new mathem. robust galaxy clustering, a clever way to reduce large distance-uncertainties from non-redshift probes & our favourite friendly neighbouring cluster, Coma!

#Astronomy folks, did an update to stellar distances happen recently? I used to use the middle star in Orion’s belt, Alnilam, as an example of the farthest stars you could see with the naked eye, at ~1900 light years. Now I'm seeing a bunch of web pages stating it as ~1200-1300 light years.

I don’t know about yours, but at mine time does seem to pass more slowly. #astronomy #humor #adolescence

Since October last year, I have had a set of solargraphy cameras set up at Rooftop Movies.

Their season, and mine, have now wrapped, so here's the writeup and the photos!

Don't know what solargraphy is? Or Rooftop Movies? Everything is explained!

Moon Visits Sister Stars

https://apod.nasa.gov/apod/image/2504/PleiadesMoon_Saiz_960.jpg

Sometimes, the Moon visits the Pleiades. Technically, this means that the orbit of our Moon takes it directly in front of the famous Pleiades star cluster, which is far in the distance. The technical term for the event is an occultation, and the Moon is famous for its rare occultations of all planets and several well-known bright stars. The Moon's tilted and precessing orbit makes its occultations of the Seven Sisters star cluster bunchy, with the current epoch starting in 2023 continuing monthly until 2029. After that, though, the next occultation won't occur until 2042. Taken from Cantabria, Spain on April 1, the featured image is a composite where previous exposures of the Pleiades from the same camera and location were digitally added to the last image to bring up the star cluster's iconic blue glow.
