So last weekend I took my Tomiyama 6x12 panoramic camera to Mount John and took some long exposures using Portra 800 film. Here's one of the images I developed yesterday. A bit much dust for my liking! #film#NewZealand#astronomy
Italian mathematician, astronomer and engineer Giovanni Domenico Cassini was born #OTD in 1625.
His observations & calculations helped to confirm & refine Kepler’s laws of planetary motion. He formulated Cassini’s Law, describing the rotational behavior of the Moon, which was crucial for understanding the Moon's synchronous rotation with the Earth. He was involved in measuring the meridian arc of Paris, contributing to the accurate determination of the shape of the Earth.

The Atacama Desert in #Chile has some of the darkest night skies in the world, perfect for #astronomy. But it's also a very seismic area. When an #earthquake hits, how do we keep our telescopes safe? We tell you all about it in this new video: https://youtu.be/y_nfFwKwmmM
(I forgot to mention like a week ago that it was) #PaperDay!
Here our group shows the 1st successful theoretical model that predicts the degree & angle of linear #polarization of scattered night-sky #light accounting for ground light sources. A 🧵 (1/14)
In the center of this image is the young star V960 Mon, located more than 5,000 light years away and located in the direction of the Monoceros Constellation. The star is surrounded by material that can potentially form planets. Observations obtained using the High Contrast Spectropolarimetric Investigation of Exoplanets instrument known as..... #astronomy#space#astrophysics#astrophotography
They want to use that to launch batches of HUNDREDS of Starlinks at once. And guess where all those Starlinks will end up? The pieces that don't make it to the ground will end up in our upper atmosphere, screwing up the stratosphere, the ozone layer, who knows what else because SpaceX isn't required to do any environmental assessments of this.
@sundogplanets I remember the first time I saw a starling launch chain. I thought my brain was melting as I saw the 50 something satellites slowly appear and drift across the sky in a straight line. It ruined any chance of shooting Astro in that portion of the sky for a good 30min.
30min can be a short time, or, and entire event when it comes to Astro photography.
I'm terrified not just of the space clutter, but the impact on our ability to appreciate the night sky. #Starlink#Astronomy
Remember Zoozve? The quasi-moon of Venus featured on Radiolab that was named after a typo on a map of the Solar System?
Now is your chance to name one of Earth’s quasi-moons. The IAU and Radiolab are holding a contest — they will pick the top 10 names, which then go to a popular vote.
The group of astronomers at Atacama Photographic Observatory APO, formed by Thierry Demange, Richard Galli and Thomas Petit, has produced this image that mainly contains the dark clouds LDN 1453, LDN 1454, LDN 1457 and LDN 1458. The mystical cosmic landscape is located in direction to the dusty regions of molecular clouds located in the Aries Constellation. The..... #astronomy#space#astrophysics#astrophotography
The spiral galaxy at the top left of this image, nicknamed the “Comet Galaxy” shows what can happen when a galaxy falls into a cluster. The galaxy cluster stripped and pushed away the Comet Galaxy’s gas, creating its gaseous tail: https://bit.ly/3y9MJyJ#astronomy
It's #MilkyWay season again here in the northern hemisphere.
I took this image using my phone last night around 2am looking south from my moderately light-polluted site in east Tucson. 5×90s subs captured in Astroshader were combined in Siril. A final stretch was applied in GIMP.
Further experiments last night. Here, I doubled the total exposure time (so, a total of 900 s). Same processing steps.
Having started in astrophotography about a million years ago using film, it blows my mind that my phone can collect the data used to make an image like this now.
