    Mars at Opposition

    October 30, 2020

    Mars

    Photographer: Howard Cohen
    Summary Authors: Howard Cohen; Jim Foster

    Orange-red Mars shines as a brilliant jewel at nightfall now, and
    since it’s just past opposition (October 13), it’s up nearly all
    night long. It was actually nearest to us on October 6 (some 32
    million miles or 69 million km distant) and is now drifting further
    away each day. The photo above shows Mars (top-center) as observed from
    a suburban avenue in Gainesville, Florida, easily visible even with
    bright streetlights. However, if you’re out on Halloween night,
    even though Mars will be nearly overhead, the full Moon (about
    1/160 of the distance to Mars and over 9000 times brighter) will
    certainly detract from its majesty. This surely won’t please the
    God of War – it might be an extra spooky night to be out and about.

    Sherwin Lakes, California

    November 30, 2020

    Capture

    Photographer: Cindy Todd
    Summary Author: Cindy Todd

    Sherwin Lakes Trailhead is less than 3 miles (4.8 km) from the town
    of Mammoth Lakes (about 7,880 feet or 2,400 m) in California's
    Eastern Sierra Nevada. The trail itself is about a 4.5-mile (7.2
    km) hike round-trip. The average elevation is around 8,270 feet (2,520
    m). It's a beautiful hike, due in part to the towering conifers and
    scenic views of Long Valley Caldera in the distance. For me, the
    sunrise reflection on Sherwin Lakes of the mountain in the background
    was especially enticing (shown above).
    This is one of the most volcanically active areas of the contiguous
    United States. For example, the numerous hot springs are all heated
    by volcanic activity. In fact, the town of Mammoth Lakes sits within
    the Long Valley Caldera which was created by an eruption
    approximately 760,000 years ago. Today, you'll find obsidian,
    basalt, pumice, tuff, rhyolite and more all around the
    area.
