Mirrors, not lenses, are the eyes of the most powerful Telescopes. Why? The observation of the Universe from Earth is subject to a phenomenon known as "seeing", because the electromagnetic radiation of celestial bodies passing through our atmosphere is distorted, blurring images captured by Optical Telescopes. Reflectors Telescopes overcome this challenge delivering sharper images by using Optical Mirrors, that not only collect light focusing it onto a point, but also can have larger dimensions of lenses embedded on Refractors Telescopes. Can you guess why Mirrors can have larger diameters than Lenses? Discover it in our article in the first comment. #optics #madeinitaly #telescopes #astronomy

Predicting the brightness of a comet is notoriously a very unreliable science, yet there's a glimmer of hope that Comet Tsuchinshan-ATLAS (C/2023 A3) could be a very good one in October as it makes its way from the Oort Cloud around the sun for the very first time. Most comets are massive naked-eye disappointments, but once in a great while, they can be amazing. Early and very optimistic predictions say it could be as bright as Sirius or Venus. Currently, Tsuchinshan-ATLAS is a very dim 10th-magnitude fuzzball in Virgo. Sky and Telescope has observing tips.

Another week...Another telescope. This week I am visiting the beautiful location of the SETI Institute Allen Telescope Array working a pipeline to image star forming regions. In 2023, I spent 65 hours on the telescope observing approximately 100 compact HII regions at 3-5GHz. Now we are going to get to see all the wonderful sources and do science! #astronomy #computing #bigdata

#DidYouKnow University of Massachusetts Amherst astronomers are part of the Event Horizon Consortium, an international team of astronomers that captured the first-ever image of a black hole? The team recently released new images of M87*, the supermassive black hole at the center of the galaxy Messier 87, using data from observations taken in April 2018. The 2018 observations include participation of the newly commissioned Greenland Telescope and a dramatically improved recording rate across the telescope array.

🔭☀️ The European Solar Telescope (EST) is specifically engineered to minimise local seeing. In a telescope, this refers to the degradation of the image quality caused by the presence of the telescope itself. This degradation occurs due to turbulent fluctuations in the refractive index of the air, often caused by temperature gradients between the telescope and its surroundings. The telescope will be built on top of a 35-meter pier to keep it above the ground layer. Furthermore, its enclosure is completely foldable to facilitate natural air circulation around the telescope. Despite the advantages of this open-air configuration, effective termal management of all sun-exposed surfaces is necessary. To that end, a combination of passive and active strategies is employed.

SVOM Mission launches successfully: scientists to study the most distant explosions of stars – Gamma bursts Photonis, part of Exosens is thrilled to announce that the SVOM (Space-based multi-band astronomical Variable Objects Monitor) mission has successfully launched into space with our cutting-edge Micro Pore Optics (MPO) detection technology onboard! Photonis Micro Pore Optics (MPO) are found on the MXT Telescope, alongside 3 other mission-critical instruments in the SVOM mission. The MPO’s, coupled with a pnCCD-equipped focal plan camera, will aid in capturing high-resolution images and spectra and will provide valuable insights into origins, composition and behavior of the Gamma bursts. By contributing to this mission, Photonis is helping scientists advance our understanding of the universe and its many wonders!

Had an amazing experience attending a workshop on telescope construction conducted by Open Space Foundation at Sri Ramakrishna Institute of Technology. Learned a lot about the science and mechanics behind building telescopes. #TelescopeConstruction #Workshop #OpenSpaceFoundation #Astronomy #HandsOnLearning"
