Panoramic Eclipse Composite with Star Trails
  Image Credit & Copyright: Stephane Vetter (Nuits sacrees, TWAN)

Explanation: 
What was happening in the sky during last week's total solar eclipse? This featured little-planet, all-sky, double time-lapse, digitally-fused composite captured celestial action during both night and day from a single location. In this 360x180 panorama, north and south are at the image bottom and top, while east and west are at the left and right edges, respectively. During four hours the night before the eclipse, star trails were captured circling the north celestial pole (bottom) as the Earth spun. During the day of the total eclipse, the Sun was captured every fifteen minutes from sunrise to sunset (top), sometimes in partial eclipse. All of these images were then digitally merged onto a single image taken exactly during the total solar eclipse. Then, the Sun's bright corona could be seen flaring around the dark new Moon (upper left), while Venus simultaneously became easily visible (top). The tree in the middle, below the camera, is a Douglas fir. The images were taken with care and planning at Magone Lake in Oregon, USA.

Bow Tie Moon and Star Trails
* Image Credit & Copyright: Haitong Yu

Explanation:
On January 31, a leisurely lunar eclipse was enjoyed from all over the night side of planet Earth, the first of three consecutive total eclipses of the Moon. This dramatic time-lapse image followed the celestial performance for over three hours in a combined series of exposures from Hebei Province in Northern China. Fixed to a tripod, the camera records the Full Moon sliding through a clear night sky. Too bright just before and after the eclipse, the Moon's bow tie-shaped trail grows narrow and red during the darker total eclipse phase that lasted an hour and 16 minutes. In the distant background are the colorful trails of stars in concentric arcs above and below the celestial equator.

Star Trails and the Bracewell Radio Sundial
 * Image Credit & Copyright: Miles Lucas at NRAO

Explanation: 
Sundials use the location of a shadow to measure the Earth's rotation and indicate the time of day. So it's fitting that this sundial, at the Very Large Array Radio Telescope Observatory in New Mexico, commemorates the history of radio astronomy and radio astronomy pioneer Ronald Bracewell. The radio sundial was constructed using pieces of a solar mapping radio telescope array that Bracewell orginaly built near the Stanford University campus. Bracewell's array was used to contribute data to plan the first Moon landing, its pillars signed by visiting scientists and radio astronomers, including two Nobel prize winners. As for most sundials the shadow cast by the central gnomon follows markers that show the solar time of day, along with solstices and equinoxes. But markers on the radio sundial are also laid out according to local sidereal time. They show the position of the invisible radio shadows of three bright radio sources in Earth's sky, supernova remnant Cassiopeia A, active galaxy Cygnus A, and active galaxy Centaurus A. Sidereal time is just star time, the Earth's rotation as measured with the stars and distant galaxies. That rotation is reflected in this composited hour-long exposure. Above the Bracewell Radio Sundial, the stars trace concentric trails around the north celestial pole.

Little Planet Lookout
* Image Credit & Copyright: Gyorgy Soponyai

Explanation:
Don't panic. This little planet projection looks confusing, but it's actually just a digitally warped and stitched, nadir centered mosaic of images that covers nearly 360x180 degrees. The images were taken on the night of October 31 from a 30 meter tall hill-top lookout tower near Tatabanya, Hungary, planet Earth. The laticed lookout tower construction was converted from a local mine elevator. Since planet Earth is rotating, the 126 frames of 75 second long exposures also show warped, concentric star trails with the north celestial pole at the left. Of course at this location the south celestial pole is just right of center but below the the little planet's horizon. the little planet's horizon.

Mount Everest Star Trails
* Image Credit & Copyright: Jeff Dai (TWAN)

Explanation:
The highest peak on planet Earth is framed in this mountain and night skyscape. On September 30, the digital stack of 240 sequential exposures made with a camera fixed to a tripod at an Everest Base Camp captured the sheer north face of the Himalayan mountain and foreground illuminated by bright moonlight. Taken over 1.5 hours, the sequence also recorded colorful star trails. Reflecting the planet's daily rotation on its axis, their motion is along gentle concentric arcs centered on the south celestial pole, a point well below the rugged horizon. The color of the trails actually indicates the temperatures of the stars. Blueish hues are from hotter stars, and yellow to reddish hues are from stars cooler than the Sun.

You've probably heard that "we are stardust," but this graphic breaks it down further & tells you what kind of stars your dust came from--and which elements didn't come from stars at all.

https://svs.gsfc.nasa.gov/13873/ #science #nature #space

This periodic table depicts the primary source on Earth for each element: from the Big Bang, massive stars, white-dwarf supernovae, merging neutron stars, low-mass stars, or other processes. In cases where two sources contribute fairly equally, both appear.


A view from an airplane window during twilight, showing the wing silhouetted against the sky. A comet –a white elongated smudge– hovers above the horizon, surrounded by scattered stars. Below, faint city lights dot the dark landscape.


I feel like we could all use some good news right now, so here you go: Bright comet Tsuchinshan-ATLAS will become visible in the evening sky starting tomorrow night.

Clear view to the west essential. Sharp eyes highly recommended. Pointers at the link.

https://skyandtelescope.org/press-releases/bright-comet-evening-view/ #space #science #astronomy #nature #photography

The bright Comet Tsuchinshan-ATLAS will first become visible in the evening sky on October 11th, appearing between Antares, the brightest star in the constellation Scorpius, and Arcturus, the brightest star in Boötes. While opening night will have it competing against twilight, it will be both higher in the sky and more visible against darker skies on subsequent evenings.


The world is indeed becoming like a really bad bad dark comedy.

I suggest they take a shit from there to see how it lands on Earth. They are already shitting all over the planet anyway...

At the same time:

Yeah....not much can be said...

👨‍🚀🚀 3... 2... 1... Liftoff!

Last night, Europe's new heavy-lift rocket, #Ariane6, successfully made its inaugural flight.

Ariane 6 can launch both heavy and light payloads to a wide range of orbits for applications such as Earth observation, telecommunication, meteorology, science and navigation.

It is a key step towards secure and autonomous 🇪🇺 access to #space.

Congratulations to the teams at European Space Agency, National Centre for Space Studies, Arianespace on this success!

Ariane 6 launches to the sky


Still some hope. Also a chance for some robotic gallows humor, I suppose. The robots did deploy, even though the craft landed basically upside down.

The "USS Western Morals" warship captured while departing Red City, just few days before her sudden disappearance.
While the incident is still under investigation, feel free to reply with your own theory about what happened.

Quick digital color over this one before ending the day.

It's hard to comprehend the vastness of space. A new atlas helps, a little.
The Siena Galaxy Atlas contains the most precise overview of galaxies in the nearby universe: 380,000 of them, each one as vast and storied as our own Milky Way. https://noirlab.edu/public/news/noirlab2328/

Optical mosaics of 42 galaxies from the SGA-2020 sorted by increasing angular diameter from the top-left to the bottom-right. Galaxies are chosen randomly from a uniform (flat) probability distribution in angular diameter. The horizontal white bar in the lower-left corner of each panel represents 1 arcminute and the mosaic cutouts range from 3.2 to 13.4 arcminutes. This figure illustrates the tremendous range of types, sizes, colors and surface brightness profiles, internal structure, and environments of the galaxies in the SGA.

Ferro 223 departing at maximum load, captured moments before the failure of the bow main support clamp. Most of the crew survived the incident.

Digital color over doodle. I tried to keep this one simple and stylized.
