franceGround-based Hypertelescope Has First Operational Components

Ground-based hypertelecope project has first images from a suspended camera and light from mirrors. They acquired the star Vega in the camera of the nacelle, for about twenty minutes, from one of the two mirrors on the ground. The image …

astronomyPath to Detecting All Blackholes in the Universe All the Time

Gravity Wave detections are rapidly increasing. The first gravity wave was detected in 2015. The science needed to accomplish this is described in the Veratasium videos below. They needed to create single wavelength lasers and use one-megawatt of power to …

satellitesUS Spy Satellites at Diffraction Limit for Resolution Since 1971

The image tweeted by Trump was at about 10-centimeter resolution. It was likely a picture taken by the US224 satellite. This was one of the upgraded keyhole satellites that have the same mirror as the Hubble Telescope (2.4 meters). It …

astronomySuper-thin X-ray Mirrors Will Make X-Ray Space Telescope 100 Times Better

Super-thin, lightweight X-ray mirrors made of silicon can make next-generation X-ray space telescopes. Above – Goddard scientist Will Zhang holds mirror segments made of silicon. These X-ray optics have been baselined for the proposed Lynx X-ray Observatory. Credits: Chris Gunn/NASA …

Carnival of Space 615 is up at Urban Astronomer. Universe Today – Subaru Telescope Sees 1800 Supernovae Japanese astronomers have captured images of an astonishing 1800 supernovae. 58 of these supernovae are the scientifically-important Type 1a supernovae located 8 billion …

constructionDeveloping Low-Cost Giant Space Telescopes Adapted to Zero-G

By altering the very premise upon which all prior telescopes rely, The High Étendue Multiple Object Spectrographic Telescope (THE MOST) overcomes all of these problems: aperture, collection area, field-of-view, spectrographic performance, and compact size. Startling, THE MOST does it at …

astronomyNASA TESS Discovers Earth Sized Exoplanet

NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size exoplanet. The exoplanet, HD 21749c, is about 89% Earth’s diameter.
