    Sunrise at Borobudur Temple

    Summary Author: Sheyenne ScrivenJin; Cadan Cummings

    The photo above shows a sunrise over the Borobudur Temple located
    in Kedu Valley on the island of Java, Indonesia. Built over one
    thousand years ago during the Shailendra dynasty, the historic site
    is the largest Buddhist temples in the world measuring 113 ft (34
    m) tall and 400 ft (123 m wide). The Borobudur Temple was used between
    approximately the years 900 to 1400 before being deserted for
    approximately four hundred years. In the early 1800’s, the site was
    rediscovered although needed considerable restoration work to return
    the site to its original greatness. With assistance from the United
    Nations Educational, Scientific and Cultural Organization (UNESCO), the
    site was restored between 1975 and 1982 and is now a World Heritage
    Site. Currently, the site attracts the most visitors of any spot in
    Indonesia as it is popular for tourism and Buddhist ceremonies during
    the Vesak holiday. Photo taken February 27, 2020.

    Hoarfrost Crystals in Maine

    April 07, 2022

    Hoarfrost 12 012222

    Photographer: John Stetson

    Summary Authors: John Stetson; Cadan Cummings

    Shown above is a photo of hoarfrost taken on January 22, 2022, near
    Sebago Lake, Maine. Hoarfrost forms in very cold weather when moist
    air is cooled to a sub-freezing dew point, which quickly converts
    the water vapor directly into these intricate ice structures. Although
    winter conditions are not prone for moist air, direct sunlight can
    promote increased water vapor near ground level through causing
    snow to either sublimate or melt and evaporate. The crystals are
    typically short-lived since they appear overnight and disappear
    gradually throughout the day as the Sun climbs higher in the sky.

    Summary Author: Stefano De Rosa
    The photo above showing snow-covered Mount Cervino in a cobalt blue
    sky, reflecting in beautiful Lago Blu (Blue Lake), was snapped in the
    Pennine Alps on the border of Italy and Switzerland. Mount Cervino
    (14,690 ft or 4,478 m), better known outside Italy as the
    Matterhorn, is one of the highest peaks in the Alps. The
    easily recognized pyramid shape towers over Lago Blu (6,293 ft or 1,918
    m) in the Aosta Valley of northwestern Italy. Crystal clear Lago
    Blu is fed by springs and surrounded by century-old larch
    trees. Photo taken on May 4, 2012.

    Dust Storm Sunset over Portugal

    June 07, 2022

    Photographer: Leonor Ferreira

    Summary Authors: Leonor Ferreira; Cadan Cummings

    Earlier this year, a dust storm passed through a large portion of
    Europe causing several days of reduced air quality. The dust storm
    was generated by a low-pressure system over the Sahara Desert
    that picked up and blew the particulates north over the
    Mediterranean Sea to Europe. A byproduct of the poor air quality
    was dramatic sunsets, with vibrant orange hues especially visible
    throughout the Iberian Peninsula. The photo above shows a sunset on
    March 17, 2022, from near Ventosa, Portugal. As is seen in the photo,
    the dust is so intense that it partially blocks out the Sun. At some
    locations during the storm, dust concentrations approached or exceeded
    100 micrograms per cubic meter of particulates sized up to 10
    microns in diameter.

    Mudcracks: Now and Then

    August 05, 2022


    Mudcracks

    Photographer: Marli Miller
    Summary Author: Marli Miller
    One of the wonderful things about sedimentary rocks is that they
    record the conditions at Earth's surface when they’re deposited -- and
    one of the most recognizable features are mudcracks. As we all can
    see, mudcracks form as wet, fine-grained sediment dries out, as shown
    by the top photo of a shoreline in the Amargosa Valley of
    southeastern California (taken in April 2022).

    The bottom photo shows mudcracks in the Proterozoic-age
    Snowslip Formation of Glacier National Park in Montana (taken
    in July 2013). These rocks, deposited in northern Montana's Belt
    Basin between about 1.4 and 1.5 billion years ago, likely formed near
    the shoreline of a shallow inland sea where the sediment was similarly
    periodically wet and dry.

    Supermoon and Micromoon Comparison

    September 07, 2022


    PSX_20220615_090728 (1)

    Photographer: Soumyadeep Mukherjee
    Summary Author: Soumyadeep Mukherjee
    This image presents a comparison between what is known as a "Supermoon"
    and a "Micromoon." The moon on the left is a photo of the supermoon
    taken in May 2021, and the moon on the right is a micromoon, from
    December 2021.

    Supermoons are observed when the full moon is closest to the
    Earth ( perigee) during the moon’s orbit about Earth. Conversely,
    micromoons are observed when the full moon is furthest from Earth
    ( apogee). The apparent diameter of the supermoon is 33.9
    arcminutes, whereas the micromoon appears only 29.7 arcminutes across.
    The 30% size difference becomes more obvious when they’re placed side
    by side.
    These two photos were taken with the same camera (Nikon D5600) and same
    lens (Sigma 150-600c) at the same focal length (600 mm) for a true
    comparison between their size. They were also captured from the same
    location in Kolkata, India.

    Thunderstorm and Rainbow over Zagreb, Croatia

    October 06, 2022

    20220911_174956-01

    20220911_190042-01

    Photographer: Neven Tandaric
    Summary Authors: Neven Tandaric; Jim Foster
    The photo at top shows the approach of a nasty thunderstorm over
    Zagreb, Croatia, as observed on September 11, 2022. Note that the
    precipitation shaft associated with this storm cell is quite
    obvious and is likely an indication of strong winds.

    The bottom photo shows a beautiful high-arching rainbow that could
    be seen as the storm departed. A portion of the secondary rainbow
    is clearly visible at upper right. This fainter bow results from a
    second internal reflection in the raindrops. The darker strip of sky
    between the primary and secondary bows is known as Alexander's Dark
    Band.

    Wafer Thin Moon and Pumpkin Sky

    October 31, 2022


    MatthewC_DSC_1834s2s

    THANKS FOR VISITING EPOD. THE BLOG SERVICE IS HAVING A TECHNICAL ISSUE.
    WE HOPE TO RESOLVE THIS WITH OUR SERVICE PROVIDER SOON.

    Photographer: Matthew Chin
    Summary Author: Matthew Chin; Jim Foster
    Can you spot the sliver of the crescent Moon? Because it was only about
    1.3% illuminated when this photo was snapped, at dawn on June 28, 2022,
    it isn’t exactly conspicuous against the pumpkin-colored sky. As night
    has now lost its grip, hordes of bats are returning to their caves
    (could this be the source of the dark smudge at lower right?) and other
    spooky, nocturnal creatures will soon be asleep in their lairs. Photo
    taken in Yuen Long, Hong Kong, on June 28, 2022, at 05:12 a.m. local
    time.

    Another Look at Lunar Pareidolia and the Tricks the Mind Plays

    The Kiss in the Moon of Zamboni - Paolo Palma

    The kiss in the moon - Paolo Palma

    Photographer: Paolo Palma

    Summary Author: Paolo Palma

    The Italian poet Filippo Zamboni and his wife Emilia Dagnen were
    watching the Moon from the Villa Reale of Capodimonte in
    Naples, Italy, in August of 1880, when they noticed the “Kiss in the
    Moon,” the loveliest pareidolia visible on the face of our
    satellite. On the bottom photo we can see the Moon rising on August 14,
    2019 ( the day before the full Moon), from the same royal garden
    where Filippo and Emilia made their discovery. Note Mt. Vesuvius,
    at left. Many astronomers, such as Cerulli, remarked that they had
    never been able to see Luna and Luno share their kiss. “Only the
    sensitivity of a poet could realize it,” Zamponi replied.

    Photo details: Nikon 42x Coolpix 510 camera; 4.3-180 mm. I gradually
    superimposed one of Zamboni's drawings on my snaps of the Moon to make
    it easier to identify the faces of the two lovers.
