Yuri Petrunin: The man behind TEC Telescopes

Thursday, December 18, 2025 by Richard Harris

When you sit down with Yuri Petrunin, founder of Telescope Engineering Company, the first thing you notice is his strong Russian accent. The second is how little he seems to care whether or not you’re impressed by it. He speaks modestly, carefully, and without pretense. He’s not trying to sell you something. He’s just telling you what he knows. And wha...

Light pollution maps are getting worse

Friday, May 10, 2024 by Richard Harris

Light pollution is a rapidly growing concern for astronomers, particularly as global urbanization and the proliferation of outdoor lighting continue. Recent studies reveal that artificial night lighting is increasing at an estimated annual rate of about 2% globally, affecting previously untouched regions and further intensifying in already lit areas. This expansion is n...

NGC 3310: A Starburst Spiral Galaxy

The party is still going on in spiral galaxy NGC 3310. Roughly 100 million years ago, NGC 3310 likely collided with a smaller galaxy causing the large spiral galaxy to light up with a tremendous burst of star formation. The changing gravity during the collision created density waves that compressed existing clouds of gas and triggered the star-forming party. The featured image from the Gemini North Telescope shows the galaxy in great detail, color-coded so that pink highlights gas while white and blue highlight stars. Some of the star clusters in the galaxy are quite young, indicating that starburst galaxies may remain in star-burst mode for quite some time. NGC 3310 spans about 50,000 light years, lies about 50 million light years away, and is visible with a small telescope towards the constellation of Great Bear Ursa Major.
