    Measuring the Blur: Because the telescope "knows" exactly what that laser star should look like (a perfect point of light), it can measure how the atmosphere is currently distorting it.

    The Shape-Shifting Mirror: This data is sent to a deformable mirror inside the telescope. This mirror has hundreds of tiny actuators behind it that adjust its shape thousands of times per second to perfectly cancel out the atmospheric turbulence.

    How the "tuning" works:

    The VLT uses a technology called Adaptive Optics to fix this in real-time:

    Creating the Reference: The lasers are fired 90 kilometers up into a layer of the atmosphere rich in sodium atoms. The laser light excites these atoms, making them glow and creating an "artificial star" exactly where the telescope is looking.

  8. You can think of those lasers as the "tuning fork" for the telescope's optical system.

    Even in a place as clear as the Atacama, our atmosphere isn't perfectly still. Pockets of warm and cool air act like moving lenses, bending light and causing that "twinkling" effect we see in stars. While it's pretty for us, it’s a nightmare for astronomers because it blurs the fine details of distant galaxies.

  17. The Day the (SFX) Circus Came

    Lancashire-based live effects wizards BPM SFX recently brought the heat to campus. With an incendiary portfolio including work with Sleep Token, Sum 41, and Oasis, they filled Studio 001 with stage-tech toys of varying lethality.

    The session gave (sensibly supervised) students a chance to play with professional kit that ran the gamut from innocuous confetti and bubble machines through to lasers, flamers, pyrotechnics, and sparklers – although it was the hand-held flamethrower that demanded the most interaction.

    Loving the smell of accelerants in the afternoon, I rolled up to try my hand at conflagration and take some photos and video in the process. With only my phone camera to hand, I noted a lot of shots with the default app were over-exposed, supersaturated and unusable. Switching to the Blackmagic Camera app for greater control, I was able to adjust ISO and increase shutter speed to better capture the experience – and thankfully record in landscape despite holding the phone vertically. The end result being a short little video to commemorate the day, even if YouTube’s compression fails to preserve the HDR intricacy of the original laser spread.

    The soundtrack forms an early work-in-progress teaser of future Trismegistus Hex material. A cheeky, if not outright blatant homage to horror movie maestro John Carpenter, but likely to change substantially in the final cut.

    We don’t normally get access to such gear during the course of our studies, so it was great to get hands-on and, for some students, spark new career possibilities.

  19. Space Development Agency (SDA) cops to issues with scaling its Proliferated Warfighter Space Architecture (PWSA). The agency is grappling with a 2-3 month schedule slip. Core issues include:

    Satellite Contact Failures: SDA and its vendors have struggled with the on-orbit checkout process – aka an inability to establish contact with one of its satellites launched in late 2025.

    Component Scarcity: Sustained shortages of optical communications terminals (OCTs) and encryption devices continue to serve as the β€œcritical path” for all vendors.

    Launch Schedule Pressure: The next scheduled mission, T1TL-A, is ~ 4 months behind schedule due to the 45-day government shutdown, a launch rocket tech glitz, and issues with onboard software for satellites. satnews.com/2026/03/08/space-d

    For 1st time, #Russian spy ship #Yantar used lasers against Royal Air Force pilots who were tracking it near UK waters

    He said he ship entered #UK waters for the second time this year in recent weeks and was located north of #Scotland when the incident occurred.

    Healey called the incident a deeply β€œdangerous move” that would be taken seriously.

  33. #MyPaperInAToot

    Modern #lasers come in various shapes and sizes, far from the high-school picture of a gain medium between two mirrors. We fabricate a spider web-shaped semiconductor laser, smaller than the width of a human hair. It can output light at different colours, and is very sensitive to pumping parts of the network. Such lasers are promising for integration in photonic chips. We are currently teaching such lasers to do #ImageRecognition !
