Bangladeshi photographer captures stunning nebulae with self-made telescope
At over 1,300 light-years from Earth, the Orion Nebula is a stellar nursery where new stars are born, making it one of the most studied objects in astronomy. Bangladeshi astrophotographer Zubuyer Kaolin has captured a striking image of the this Orion Nebula from his rooftop in Dhaka using a telescope built with locally sourced materials. Zubuyer's image offers a detailed view of the nebula's bright core, where young stars are emerging, and captures the surrounding regions of dust and gas that form into intricate, colourful filaments. Zubuyer's photograph showcases the nebula's intricate dust clouds, bright stars, and vibrant gas filaments, and it is gaining attention for both the remarkable clarity of his image and the resourcefulness required to build a telescope that could capture such detail. After the image went viral on social media, we decided to track him down. This is Zubuyer's story. Zubuyer assembled his telescope from accessible materials, using his skills in engineering and design to overcome technical limitations. The primary telescope tube was constructed from 4- and 5-inch PVC drainage pipes sourced from a local hardware store. For the 102mm aperture objective lens, he turned to an online vendor, as creating such a lens independently would have required complex materials and equipment. For focusing, rather than using a traditional rack-and-pinion or Crayford focuser, he opted for a lead screw mechanism typically found in linear actuators. Controlled by a stepper motor connected to a microcontroller, this mechanism allows precise focus adjustments and maintains focus stability throughout each session, a crucial factor in astrophotography where minute shifts can impact image clarity. This inventive solution prevents accidental slips, a common issue with more traditional focusing methods, ensuring that Zubuyer can capture consistently sharp images even over extended periods.

In 3.75 billion years, the Milky Way will collide with Andromeda, merging into a new galaxy and transforming the night sky.
In about 3.75 billion years, the Milky Way and Andromeda galaxies will collide in a cosmic event of unimaginable scale. Andromeda is currently racing toward us at 250,000 mph—fast enough to circle Earth in just six minutes. This galactic collision will not destroy Earth, but it will completely transform the night sky. The two massive galaxies will engage in a gravitational dance lasting billions of years, merging into a single, giant galaxy. Stars will be flung into new orbits, and some may even be ejected into intergalactic space. For distant observers, the event would resemble a stunning, surreal display as the shapes of both galaxies shift and intertwine. This celestial spectacle will mark the end of the Milky Way as we know it, creating a new, unified galactic structure while reshaping the cosmos.
