Description:

Summer is the season for Noctilucent Clouds Full Moon and Perigee Moon converge for a Supermoon Track down two asteroids, Ceres and Vesta Planetary pairings of Saturn and Mars, Jupiter and Venus The Perseid meteor shower peaks The Equinox restores balance to days and nights Mars meets its rival, Antares An early Harvest Moon occurs in September Perseid Meteorite shooting across the night sky – August 2015August s Perseid meteor shower was a good one and testament to that is this great photograph of a Perseid meteorite from 12 August 2015. It was taken by amateur astrophotographer Andrew Davidhazy at 10:30pm EST from a location near Rochester in New York state, USA. The photo was taken with a Canon 5D Mark II (on a tripod) which had been set up to take 15 second long exposures with a 50mm lens at a large lens opening (f/2) and high sensor speed (of 2000). Notwithstanding the light pollution that there was to contend with, Read the rest of this post The Sun, our nearest star, by John ChumackWhen snow covers the ground and we shiver from scant Sun rays and long nights, it’s not hard for our thoughts to turn to our nearest star. One cure for wintertime blues is to travel south to a place where the Sun shines a bit longer and warmth still bakes the Earth.But for the astronomically minded, sometimes we think about getting closer to the Sun in other ways. The Sun is the closest star to Earth, even though sometimes it feels completely absent. But what are the other stars close to Earth and why can’t they help keep our toes from freezing? I can’t really help you with the second question, but for the first question, we can explore all the close stars to Earth. Read the rest of this post Aurora Photo by John ChumackAll amateur astronomers have a wish list of objects they would like to observe. When they first start observing, the list is modest, with objects such as the moons of Jupiter, the rings of Saturn, craters on the Moon, the Andromeda Galaxy, the Orion Nebula, and so forth.By this point in my life, I have seen these objects multiple times. They are beautiful and always worth a look, but they certainly wouldn’t be something to put on my wish list anymore. My current wish list is a bit more exotic. Some of the items I have seen but want to see again, while others I haven’t seen and still others I will never see. But they make my wish list nonetheless. Read the rest of this post A Partial Lunar Eclipse during MoonsetThe total lunar eclipse was going to occur from about 5:30 to 6:30 on Wednesday morning. My alarm was set for 6:00, like usual, and the forecast was for perfectly clear skies.I was awake fifteen minutes before my alarm but patiently waited until six o’clock, because the only upstairs windows that face west where the eclipsed Moon was setting are in my children’s bedrooms. I was not awake enough to go downstairs nor mean enough to wake them unnecessarily early. At 6:00 I walked into my son’s bedroom and raised his blinds, like I do every morning to wake him. This has become less effectual as the school year draws on and it’s still dark in the morning. This morning there wouldn’t even be moonlight to wake him, as the fully eclipsed Moon was shining dimly with a gray pallor.

I stood in my driveway looking up at the stars arrayed above while fog swirled around my feet. These are not ideal conditions for observing, but at least the stars can be seen, whereas the clouds had been blocking all manner of wonders, including the recent aurora, for nights on end. Read the rest of this post M8, The Lagoon Nebula in Sagittarius, by John ChumackSagittarius is an incredibly rich area for stargazing, but it’s only easily viewable for a short time. Summer is the best season for observing, but even then it stays low on the southern horizon. Sagittarius is an easy constellation even for children to spot because it has a grouping of stars that looks almost exactly like a teapot.

Teach your friends and family the most important summer constellations with this handy guide on what star formations are overhead.

And in fact, sometimes vacations provide for the best stargazing.Over spring break this year my family and I did a tour of the national parks, starting and ending our vacation in Las Vegas, one of the most light polluted locations on Earth. But McCarran International airport made for a good spot to begin our travels first to Utah’s national parks, then to Great Basin National Park in Nevada along the loneliest highway in America, and finally to Death Valley National Park in California, before the short jog back to Las Vegas.
