Science, education, and arts

Hi, I’m

Ogetay.

Astrophotographer, astrophysicist,
and science communicator.

About Me

I'm a scientist, visual artist, and science communicator working at the intersection of physics, astronomy, technology, and visual storytelling.

I'm currently a PhD candidate in Physics at Michigan Tech, specializing in astrophysics. My research focuses on superluminal phenomena in dispersive media, particularly the theory, coherence, and observability of Cherenkov radiation. My work bridges theoretical physics, numerical modeling, and the detection of high-energy phenomena.

For more than five years, I've been part of NASA's Astronomy Picture of the Day (APOD) team as a guest editor, outreach specialist, and software engineer. APOD reaches a global audience and is translated into more than 20 languages.

I've been communicating science to the public for more than a decade. I founded Rasyonalist, one of Turkey's major popular-science platforms, where I wrote more than 300 articles, edited more than 1,000, and led a team of over 10 volunteers before its merger with Evrim Ağacı, Turkey's largest popular-science organization.

Today, much of my outreach centers on video, scientific visualization, and educational technology. I create content about astronomy, physics, and the process of science—not only explaining what we know, but how we know it, and how to reason critically about evidence. I previously created more than 70 video scripts for Barış Özcan and Evrim Ağacı, reaching a combined audience of over 55 million views, and I now focus primarily on my own YouTube channel and independent science projects.

I'm also a photographer with more than 15 years of experience, specializing in astrophotography. My work combines scientific curiosity with artistic interpretation and has been awarded internationally and featured by platforms including APOD, AstroBin, Astronomy Magazine, ScopeTrader, and Sky & Telescope.

Measurements and visualizations

Citizen Astronomy

CAst is a desktop application for scientists, educators, and citizen scientists. It takes astronomical images and turns them into scientific measurements and visualizations for research and teaching.

Alpha release. Each download is about 2 GB. Installation notes · Mode guides

Differential Photometry

Select the folder where you have series of images. CAst will identify the variable stars and exoplanets in your image field and create light curves of all at once. It generates AAVSO-ready scientific outputs, along with advanced tool options much as machine learning.

Asteroid / Comet Detection

Find the asteroids and comets in your field just by selecting your image folder. CAst will find all, track and measure them. To make discoveries, you can use advanced tools such as full synthetic tracking.

Sky Explorer

Want to know what objects are in your image? Or want to query some specific object types? CAst can identify and categorize all the known objects by searching scientific databases and bring relevant information. You can also compare your image with surveys, side by side, to confirm your discoveries.
