The news that “Vulcan” topped the poll results taken by the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California as a possible name for one of the two tiny moons newly discovered to be orbiting Pluto has gotten quite a bit of press this week. In 2012, Mark Showalter of SETI, working with scientists on the New Horizons mission sending a probe to Pluto, found a tiny fifth moon orbiting the icy world.
A particularly bright fireball was observed earlier today over a wide area in Russia. Of even greater significance was the very strong sonic boom associated with the passage of the meteor through Earth’s atmosphere.
At our evening observing sessions at the Public Observatory, we’ve shared views of Mars, Jupiter, Saturn, the Moon, and other astronomical objects with thousands of visitors. But Neptune, the most distant planet in the Solar...
Astronomy enthusiasts around the world are gearing up for Tuesday’s celestial show: the transit of Venus across the face of the Sun. The small black dot of Venus, silhouetted against the bright Sun, will be visible with safe solar telescopes and, to those with especially good vision, with the naked eye when protected by eclipse glasses.
If you visit the Public Observatory during its daytime hours in May (1–3pm on Wednesday through Saturday, weather permitting), you can use the 16” telescope to observe an object which looks a lot like the Moon. Hanging in a blue sky, it shines with yellowish reflected sunlight.
The universe is about 13.7 billion years old and has expanded since its beginning at the Big Bang. Because distant objects appear to be receding as the universe expands, the light from them is “stretched” out, altering its wavelength to the red part of the electromagnetic spectrum. This “redshift” can be measured for every object in deep space.
