NASA Astronomy Picture of the Day:

Taken on July 29 and July 30, a registered and stacked series of exposures creates this dreamlike view of a northern summer night. Multiple firefly flashes streak across the foreground as the luminous Milky Way arcs above the horizon in the Sierra de Órganos national park of central Mexico, The collection of bright streaks aligned across the sky toward the upper left in the timelapse image are Delta Aquariid meteors. Currently active, the annual Delta Aquarid meteor shower shares August nights though, overlapping with the better-known Perseid meteor shower. This year that makes post-midnight, mostly moonless skies in early August very popular with late night skygazers. How can you tell a Delta Aquariid from a Perseid meteor? The streaks of Perseid meteors can be traced back to an apparent radiant in the constellation Perseus. Delta Aquariids appear to emerge from the more southerly constellation Aquarius, beyond the top left of this frame. Of course, the bioluminescent flashes of fireflies are common too on these northern summer nights. But how can you tell a firefly from a meteor? Just try to catch one.

La Fuentona, Muriel de la Fuente, Soria, Spain. The natural spring is a natural monument since 1998. There are only 6 such monuments in the Community of Castile and León (the biggest in Spain by surface).

NASA Astronomy Picture of the Day:

A small, dark, nebula looks isolated near the center of this telescopic close-up. The wedge-shaped cosmic cloudlet lies within a relatively crowded region of space though. About 7,000 light-years distant and filled with glowing gas and an embedded cluster of young stars, the region is known as M16 or the Eagle Nebula. Hubble's iconic images of the Eagle Nebula include the famous star-forming Pillars of Creation, towering structures of interstellar gas and dust 4 to 5 light-years long. But this small dark nebula, known to some as a Bok globule, is a fraction of a light-year across. The Bok globule stands out in silhouette against the expansive background of M16's diffuse glow. Found scattered within emission nebulae and star clusters, Bok globules are small interstellar clouds of cold molecular gas and obscuring dust that also form stars within their dense, collapsing cores.

Édouard Manet's The Café-Concert, 1878. Scene set in the Cabaret de Reichshoffen on the Boulevard Rochechouart, where women on the fringes of society freely intermingled with well-heeled gentlemen. Today is International Beer Day.

                  Ghosts

    There are ghosts in the room.
As I sit here alone, from the dark corners there
They come out of the gloom,
And they stand at my side and they lean on my chair

    There’s a ghost of a Hope
That lighted my days with a fanciful glow,
In her hand is the rope
That strangled her life out. Hope was slain long ago.

    But her ghost comes to-night
With its skeleton face and expressionless eyes,
And it stands in the light,
And mocks me, and jeers me with sobs and with sighs.

    There’s the ghost of a Joy,
A frail, fragile thing, and I prized it too much,
And the hands that destroy
Clasped its close, and it died at the withering touch.

    There’s the ghost of a Love,
Born with joy, reared with hope, died in pain and unrest,
But he towers above
All the others—this ghost; yet a ghost at the best,

    I am weary, and fain
Would forget all these dead: but the gibbering host
Make my struggle in vain—
In each shadowy corner there lurketh a ghost.

Ella Wheeler Wilcox (November 5, 1850 – October 30, 1919) was an American author and poet. Her works include Poems of Passion and Solitude, which contains the lines "Laugh, and the world laughs with you; weep, and you weep alone." Her autobiography, "The Worlds and I", was published in 1918, a year before her death. Read more

NASA Astronomy Picture of the Day:

A long time ago in a galaxy 50 million light-years away, a star exploded. Light from that supernova was first detected by telescopes on planet Earth on July 14th though, and the extragalactic transient is now known to astronomers as supernova 2025rbs. Presently the brightest supernova in planet Earth's sky, 2025rbs is a Type Ia supernova, likely caused by the thermonuclear detonation of a white dwarf star that accreted material from a companion in a binary star system. Type Ia supernovae are used as standard candles to establish the distance scale of the universe. The host galaxy of 2025rbs is NGC 7331. Itself a bright spiral galaxy in the northern constellation Pegasus, NGC 7331 is often touted as an analog to our own Milky Way.

Triumph of St. Ignatius of Loyola by Andrea Pozzo, celebrates the work of Ignatius of Loyola and the Society of Jesus in the world by depicting the saint welcomed into paradise by Christ and surrounded by allegorical representations of the four continents. The trompe-l'œil fresco adorns the flat ceiling of the Church of St. Ignatius of Loyola at Campus Martius. Today is Ignatius of Loyola's feast day.

"Barney, my barber, is about to take down his red white and blue rotating tubular pole for good. He’s been cutting hair since back in the day when South Enders either opted for a butch or let it grow their arses, as Barney puts it. You could tell a man’s politics by his hair back then. Needless to say, I didn’t require Barney’s services back in my radical days. And Barney probably would’ve refused to let me sit in his leather chair. “Go to a stylist, someone who’ll cut a woman’s hair.”...... More at The Skeeter Daddle Diaries ➜
