June 2015 Sky & Telescope Experiencing the Ethereal

The universe is a vast place largely beyond human comprehension. Yet even if we can't really understand the concept of 1 billion light-years, we can still experience the universe with our limited capabilities — whether that be through the spellbinding images from the Hubble Space Telescope, featured in our cover story celebrating Hubble's 25th anniversary, or through the low-tech but just as captivating solargraphs that capture the motions of the Sun. We experience the universe in an even more visceral way when we observe through our eyes and telescopes, for example, by charting a galaxy cluster more than 1 billion light-years a way. Or, as Sky & Telescope readers have done for decades, by precisely measuring crater timings during a lunar eclipse. As we enter into summer, Saturn, the Moon, and the stars of the Serpens Caput beckon, and the universe awaits.
