Nova over Thailand
A nova in Sagittarius is bright enough to see with binoculars. Detected last month, the stellar explosion even approached the limit of naked-eye visibility last week. A classical nova results from a thermonuclear explosion on the surface of a white dwarf star -- a dense star having the size of our Earth but the mass of our Sun. In the featured image, the nova was captured last week above ancient Wat Mahathat in Sukhothai, Thailand. To see Nova Sagittarius 2016 yourself, just go out just after sunset and locate near the western horizon the constellation of the Archer (Sagittarius), popularly identified with an iconic teapot. Also visible near the nova is the very bright planet Venus. Don’t delay, though, because not only is the nova fading, but that part of the sky is setting continually closer to sunset.

The Klamath tribes, which also include the the Modocs and the Yahooskin, didn’t encounter a white person until 1826, when a fur trapper wandered into their territory. Just 28 years later, in 1864, the tribes agreed to cede 23 million acres of their land in exchange for a reservation. In 1954, an act of Congress ended federal recognition of the Klamath tribes, which meant that they lost their reservation and the accompanying human services. Their rights as a federally recognized tribe were not restored until 1986. This portrait of a Klamath woman was taken in 1923, by Edward Curtis, and is now in the Library of Congress.
