A Dusty Fingerprint in Space

A new image from NASA's James Webb Space Telescope reveals a remarkable cosmic sight: at least 17 concentric dust rings emanating from a pair of stars. Just 5,300 light-years from Earth, the star duo are collectively known as Wolf-Rayet 140. Each ring was created when the two stars came close together and their stellar winds (streams of gas they blow into space) collided so forcefully that some of the gas was compressed into dust. The stars' orbits bring them together about once every eight years, and forms a half-shell of dust that looks like a ring from our perspective. Like a cosmic fingerprint, the 17 rings reveal more than a century of stellar interactions—and the "fingerprint" belonging to Wolf-Rayet 140 may be equally unique. Other Wolf-Rayet stars produce dust, but no other pair are known to produce rings quite like Wolf-Rayet 140.

Lookout Mountain Milky Way

Victor: “…a beautiful evening and star-filled night on Lookout Mountain, Oregon”

Lookout Mountain, elevation 6,536 feet (1,992 m), is the second highest peak in Oregon’s Mount Hood National Forest and the highest point in Badger Creek Wilderness. It sits about 8 miles (13 km) east-southeast of Mount Hood, separated from it by the valley of the East Fork Hood River.

From its summit and with good visibility, one may see (from approximately west and moving clockwise) Mt. Hood, Mt. St. Helens, Mt. Rainier, Mt. Adams, Broken Top, South Sister, North Sister, Mt. Washington, and Mt. Jefferson with the unassisted eye.
