Both the plane of the Solar System (called the ecliptic) and the plane of the Milky Way pass through Scorpius—the scorpion. As a result, you can find both the planets of our Solar System (which move along the ecliptic), and many kinds of deep sky objects in this constellation. Scorpius’s brightest star, Antares, is also known as the Heart of the Scorpion, because of it’s reddish hue and location in the chest of the scorpion. Being both red in color, and near the ecliptic, Antares is a rival of sorts to the planet Mars, which is also reddish in color, and occasionally passes through Scorpius. The name Antares means “opposing Mars”.
M4 is a globular star cluster located near the bright, orange star Antares, in the constellation Scorpius. It is on the small side, as globular clusters go—only 70-75 light-years across. It is about 7,200 light-years away, which makes it possibly the closest globular cluster to our solar system.
Kitt Peak has an abundance of clear nights, but that doesn’t mean the clouds never move in. We hope you’ll join us again another time when our dark mountain skies are at their best!
The ecliptic is a path in the sky, forming a great circle around the Earth, which the Sun and other planets of the Solar System move along. It is formed where the plane of the Solar System intersects with the Earth’s sky.
That clumpy band of light is evidence that we live in a disk-shaped galaxy. Its pale glow is light from about 200 billion suns!
Jupiter is the largest planet in the Solar System, a “gas giant” 11 Earth-diameters across. Its atmosphere contains the Great Red Spot, a long-lived storm 2-3 times the size of the Earth. The 4 large Galilean satellites and at least 63 smaller moons orbit Jupiter.
3.5 Meter WIYN Telescope
The WIYN Observatory is owned and operated by the WIYN Consortium, which consists of the University of Wisconsin, Indiana University, National Optical Astronomy Observatory (NOAO), the University of Missouri, and Purdue University. This partnership between public and private universities and NOAO was the first of its kind. The telescope incorporates many technological breakthroughs including active optics hardware on the back of the primary mirror, which shapes the mirror perfectly, ensuring the telescope is focused precisely. The small, lightweight dome is well ventilated to follow nighttime ambient temperature. Instruments attached to the telescope allow WIYN to gather data and capture vivid astronomical images routinely of sub-arc second quality. The total moving weight of the WIYN telescope and its instruments is 35 tons. WIYN has earned a reputation in particular for its excellent image quality that is now available over a wider field than ever before through the addition of the One Degree Imager optical camera.
