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

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
