Finally! After receiving my replacement ZWO 2600MM Pro (oil leak and fan causing vibration issues), we experienced an uncharacteristic three weeks of cloudy weather. This was a test shot of the Cygnus Wall in the North America Nebula. The image is 30 x 5min exposures in hydrogen alpha. #astronomy #astrophotography #astrophoto #space #nebula #deepspaceobject
Astronomers Pin Down the Age of the Most Distant Galaxy: Seen 367 Million Years After the Big Bang

As promised, the James Webb Space Telescope is finding the Universe's earliest galaxies, forging a link between them and modern galaxies.

Newly published research suggests that skyglow is increasing around the world on average at a rate much higher than previously thought. Read more about how citizen-scientists contributed to this new understanding and what the results mean for efforts to reduce light pollution and bring back starry nights.

Please stop using “mom” as an example of an unsophisticated user of technology. This reinforces harmful stereotypes.

Instead, I suggest using “congressperson”.

Matt Gaetz went on MSNBC last night to claim he never begged Trump for a pardon. Riiiiight. 🙄

Watch Gaetz squirm as Ari Melber brings the instant video receipts rebutting his lie. The schadenfreude is real: https://www.comicsands.com/ari-melber-matt-gaetz-pardon-2659335236.html?utm_source=mastodon&utm_medium=toot&utm_campaign=sand

APOD: 2023 January 25 – LDN 1622: The Boogeyman Nebula

A different astronomy and space science related image is featured each day, along with a brief explanation.

Added some OIII. Between the light pollution, wind, and tracking issues, the image is messy. But, with the weather being what it has been, gotta work with what I get. The Rosette Nebula is about 5000 light years from earth and 130 light years across. Here you can see about 1/4 of the nebula. #photography #astrophotography #space #deepspace #DSO #rosettenebula #nebula
Here is a close-up of the Rosette Nebula (NGC 2237). The Rosette Nebula is about 5000 light years from earth and 130 light years across. Here you can see about 1/4 of the nebula. This image is composed of 44 x 5min (3.7 hours total integration) exposures using a hydrogen alpha filter. If current weather patterns persist, I'll complete the image sometime in 2055 ;) #photography #astrophotography #space #deepspace #DSO #rosettenebula #nebula

Fission is in the news, but few recognize that a woman physicist was behind the discovery.

Lise Meitner’s brilliance led to the discovery of nuclear fission. But her long time collaborator Otto Hahn, was awarded the Nobel Prize in Chemistry w/o her in 1944, even though she had given the first theoretical explanation.

Albert Einstein called Meitner “our Marie Curie." She also adamantly refused to work on the atomic bomb during WWII. https://www.aps.org/publications/apsnews/201502/physicshistory.cfm #women #history #science #HistoryRemix
