Picture perfect: Mission managers say the telescope's mirror segments have been aligned and have focused on single stars, a critical milestone, and the telescope is working flawlessly.
China's 500-meter-wide FAST telescope boasts greater sensitivity and a deformable mirror
Tele Vue Optics, founded in 1977, has been thrilling amateur astronomers since 1979. It is our mission. It's in the materials we choose, the designs we create, the craftsmanship we demonstrate...the images we deliver.
Salut, après avoir désaluminé mon miroir, fabriqué un barillet 6 points, et comme le soleil n'est toujours pas là, je me lance dans la fabrication d'un newton trusstube. Après avoir étudié (c'est un grand mot) pas mal de configurations j'ai fini par tomber sur le site du soleye 300, je suis tombé...
The Celestron StarSense Explorer Dob is a clever upgrade to a traditional Dobsonian telescope, thanks to an integrated smartphone dock and app.
Astronomers have directly observed two exoplanets shedding their outer layers into space for the first time. The observations provide a rare look into the interiors of these planets, which has remained challenging even for Earth.

And in a process dubbed "spaghettification," anything that gets too close—be it a star, planet, or spacecraft—will be stretched and squished like putty.

They've confirmed for the 1st time that this newly formed planet - labeled PDS 70b - is still gathering material from the dust and gas around its star. They're literally watching this new world develop and grow.
Astrophotography is a hobby rapidly gaining popularity thanks to the fast advancing CMOS sensor technology. Over a decade ago, the light recording material employed in astrophotography was primarily chemical emulsion. Its low sensitivity makes it very hard to record the weak signal from deep space. In addition, the lack of real-time feedback is a huge source of frustration for beginners. Operational errors such as out-of-focus can only be realized after several nights of hard work after the film is developed. In the mid 90s, the advent of cooled CCD cameras provided solutions to both the sensitivity and real-time feedback problems. However, their high prices and miserably small sensor areas limited their uses to only a few kinds of astrophotography and to very enthusiastic astrophotographers. While CCDs revolutionized astronomical research, this technology has never really changed the landscape of amateur astrophotography. The true turning point took place in 2002. After Fujifilm announced its FinePix S2Pro DSLR and showcased amazing astronomical pictures taken by this camera, people started to seriously explore DSLRs for astrophotography. DSLRs can provide real-time feedback, which is very important for beginners. They have sensitivities not much worse than CCDs, and DSLRs with large sensors (APS-C) are quite affordable nowadays. Today’s landscape in astrophotography is shaped by a series of CMOS-based DSLRs from Canon, but DSLRs and mirrorless cameras based on Sony sensors are gaining popularity very quickly.
The most powerful space telescope ever built will have to wait on the ground for a few more months into 2019 before launching to the High Frontier and looking back nearly to the beginning of time and unraveling untold astronomical secrets on how the early Universe evolved – Engineers need a bit more time to complete the Webb telescopes incredibly complex assembly and testing here on Earth.

radio telescope, astronomical instrument consisting of a radio receiver and an antenna system that is used to detect radio-frequency radiation between wavelengths of about 10 metres (30 megahertz [MHz]) and 1 mm (300 gigahertz [GHz]) emitted by extraterrestrial sources, such as stars, galaxies, and quasars. (See radio and radar astronomy.) Extraterrestrial radio emission was first reported in 1933 by Karl Jansky, an engineer at the Bell Telephone Laboratories, while he was searching for the cause of shortwave interference. Jansky had mounted a directional radio antenna on a turntable so that he could point it at different parts of the sky
