  • What is Sony’s Exmor Technology Anyway?

    Good background on on Sony Exmor sensors, especially the GSTAR-EX3 used in astronomy cameras like the  GSTAR-EX3 or  Hypercam IMX178   What is Sony’s Exmor Technology Anyway? A personal CMOS tutorial by FRAMOS’ Darren Bessette I was just as surprised as all of you were when I heard the news that Sony is discontinuing their CCD line…

  • Control Your Telescope Using Stellarium & Arduino

    I think the ultimate telescope control project based around either an Arduino or Raspberry Pi is still a little way off, but this certainly has some promise.    Control Your Telescope Using Stellarium & Arduino I am fascinated by astronomy since the first time I looked to the night sky. Recently, I bought a 8″…

  • Discovery alert! A nearby super Earth

    Cool! A nearby “Super Earth” –   only 21 light-years away in the inner habitable zone of its small, red ‘M dwarf’ star. Almost 3 times more massive than Earth, this exoplanet is 21 light-years away. It takes only two weeks to orbit its star, closer than Mercury is to the Sun. But since M dwarf stars…

  • New gravitational wave detection shows shape of ripples from black hole collision

    Picked up from twin instruments, Ligo and Vigo.  New gravitational wave detection shows shape of ripples from black hole collision For the first time, astronomers have detail on the 3D pattern of warping that occurs when black holes with masses of 31 and 25 times that of the sun collide Source: www.theguardian.com/science/2017/sep/27/new-gravitational-wave-detection-shows-shape-of-ripples-from-black-hole-collision-ligo-virgo

  • CMOS vs CCD in the field of spectrography

    Very detailed article about the differences between CMOS and CCD cameras.    Comparison of CMOS and CCD in the field of spectrography For spectrographic applications in particular, I compare the performance of Charge-Coupled Device (CCD) sensor with the latest generation of Complementary Metal Oxide Semiconductor (CMOS) sensors available to amateurs at the date (August 2017).…

  • Earth’s carbon points to planetary smashup

    Further evidence about the Earth being struck by a large, Mercury size object in the early life of the Solar System Research by Rice University Earth scientists suggests that virtually all of Earth’s life-giving carbon could have come from a collision about 4.4 billion years ago between Earth and an embryonic planet similar to Mercury.…

  • Pluto’s Methane Snowcaps on the Edge of Darkness

      Pluto’s Methane Snowcaps on the Edge of Darkness The southernmost part of Pluto that NASA’s New Horizons spacecraft could “see” during closest approach in July 2015 contains a range of fascinating geological features, and offers clues into what might lurk in the regions shrouded in darkness during the flyby.

  • MAVEN Reveals Speed of Solar Wind Stripping Martian Atmosphere

    The MAVEN mission has identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment that might have supported surface life to the cold, arid planet Mars is today.

  • New Technology Telescope bathed in red

    Rear view of New Technology Telescope (NTT) at ESO’s La Silla Observatory, located on the outskirts of the Chilean Atacama Desert, 600 km north of Santiago de Chile. Inaugurated in 1989, the 3.58-metre NTT was the first telescope in the world to have a computer-controlled main mirror. This mirror is flexible; in a process called adaptive optics, its…
