The Stars in Cygnus

February 02, 2022

GregParker_stars like sand

Photographer: Greg Parker

Summary Author: Greg Parker

Without looking at the title you might imagine that what’s being shown
here are embedded specks of quartz on the surface of a sandstone
rock, rather than a view of a particularly dense portion of the
Milky Way. The camera is pointing toward the constellation of
Cygnus the Swan. In this small part of the sky, there’s likely more
than 150,000 stars, according to the Registar program. Amazingly,
all the grains of sand on the world’s beaches pales in comparison
to the number of stars estimated to exist in the entire universe.
Compare this image with the Earth Science Picture of the Day for
February 26, 2014. Photo taken on November 20, 2021.

Photo details: Taken with a Canon 200 mm prime lens and a Starlight
Xpress M26C, one shot color CCD.

California Nebula (NGC 1499)

March 02, 2022

Photographer: Greg Parker

Summary Authors: Greg Parker; Cadan Cummings

The photo above shows the California nebula (NGC 1499) located in
the constellation Perseus. As its name implies, the shape of
California nebula roughly resembles the U.S. state. The
emission nebula is approximately 1,000 to 1,500 light years from
Earth. Visible below NGC 1499 is the star Xi Persei, which ionizes
the nebula's hydrogen atoms and gives the feature its iconic glow.

Photo Details: I processed this image from Deep Sky Survey (DSS2) data
which is available online. Image was processed from red and blue data
channels with a synthesized green channel. Noel Carboni's Astronomy
Actions automate this process in Photoshop.

Lightning and the Eiffel Tower

August 02, 2022

Photographer: Bertrand Kulik

Summary Author: Bertrand Kulik; Jim Foster

The photo above showing a forked lightning stroke near the
Eiffel Tower in Paris, France, was captured during a
thunderstorm on May 15, 2022. From the balcony of my apartment
window (in District 15), this cloud-to-ground bolt appeared to be a
much-distorted outline of the famed tower itself. At 916 ft (279 m) in
height and hundreds of feet higher than any nearby structure, the
Eiffel Tower is not only the visual focal point of Paris but is one of
the most eye-catching objects of any city anywhere in the world. On
average, it's the target of lightning strikes about 10-times per
year.

Photo details: Canon EOS 5D Mark III camera; EF 50 mm; f/1.8 STM;
ƒ/13.0; 50.0 mm; 2 50.

Mount Etna Eruption of May 29, 2022

Photographer: Giovanni Tumino

Summary Author: Giovanni Tumino

During one of the numerous paroxysms of Mt Etna (Sicily, Italy), I
decided to spend the night filming the lava flow it generated. This
flow emanated from a new eruptive mouth that opened at
approximately the 2,800 m (9,186 ft) level on May 29, 2022. Though
these flows look ominous, fortunately the Bove Valley acts as a
container for the lava flow that would otherwise pour over the Etnean
towns. Photos taken on June 2, 2022.

Wafer Thin Moon and Pumpkin Sky

October 31, 2022

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.

Cumulus Clouds with Spikes

December 02, 2022

Photographer: Mila Zinkova

Summary Author: Mila Zinkova; Jim Foster

Shown above are curious shaped, cumulus clouds that were observed
from near my home in San Francisco, California, on April 19, 2022. The
spike-like features have horseshoe shapes in some cases, as shown in
the bottom photo. Perhaps these spikes and horseshoes are caused by
convection -- intense localized heating of the most optically
thick portion of cloud by the strong April sun. However, because the
atmospheric environment where the clouds formed wasn't suitable
( stable atmosphere) for widespread building, they remained overall
fairly “flat” in appearance. Click here to see a video of these
clouds.
