There’s a little bit of showmanship in sharing stargazing. It helps to be mindful that other people might not be quite as wowed as you are by the sight of a faint fuzzy thing in the eyepiece of a telescope (even if it is the combined light of hundreds of billions of stars that has been traveling tens of millions of years before ending the journey on our retinas). So you select what you share with care and save the most awesome for last. This summer, that’s Saturn.
I love hearing the reactions of people when they see Saturn in a telescope: “wow”, “groovy”, “cool”, “boss”, “dope” or “sweet” depending on the generation. Some just curse reverentially while a few check the telescope to see if I snuck in a picture. Saturn is stunning surrounded by its moons and rings. This summer, those rings are at their widest when viewed from our planet.
Saturn will be its closest to Earth the night of June 14-15. During this opposition, Earth is directly between the Sun and Saturn, so we get to say “Saturnian Syzygy” because all three are in a straight line. Even at its closest, Saturn is still almost a billion miles from Earth. The sunlight we see reflected off Saturn and its rings left 75 minutes before we see it.
Look for Saturn this month in the southeast after sunset, in the south around midnight, and in the southwest before sunrise. It will be the brightest object in its part of the sky except for Antares (to its right) which has an orange-red color and is not quite as bright as Saturn. The viewing gets better as we get further into June. On June 1st, Saturn rises in the southeast at 9:21pm, is highest in the south at 1:56am, and sets in the southwest at 6:35am. By June 30th, Saturn rises, transits, and sets two hours earlier.
Saturn is the slowest of the naked-eye planets. It takes almost 30 years to orbit the Sun and spends about 2 ½ years in each constellation as viewed from Earth. Saturn will be in Ophiuchus the Serpent-Bearer until November when it moves into Sagittarius the Archer. When you are stargazing in 2047, be sure to notice that Saturn has returned to Ophiuchus!
You can have a look at Saturn through a telescope at free public programs. Journey to Kickapoo Valley Reserve on June 8 for Spring Trails by Light of the Strawberry Moon (8-10 pm). Watch the Moon and Saturn rise together and catch a glimpse of Jupiter and its moons. Gather at the visitor center and hike down to Old 131 Trail. Starsplitters of Wyalusing State Park offer a Public Program on June 17 (8:30 pm) and a Star Party on June 24 (8:30 pm).
You won’t be able to see it, but the Cassini spacecraft is nearing the end of its mission. It has been exploring Saturn and its moons and rings since 2004 and is running low on fuel. For its finale, it will make multiple passes through the rings of Saturn to make its closest observations ever. On September 15, it will be deliberately plunged into the atmosphere of Saturn so that any surviving microbes do not contaminate the moons of Saturn where there may be life. Imagine it orbiting the ringed world and enjoy your summer of Saturn.
