NASA Astronomy Picture of the Day:

What if you saw your shadow on Mars and it wasn't human? Then you might be the Opportunity rover exploring Mars. Opportunity explored the Red Planet from 2004 to 2018, finding evidence of ancient water, and sending breathtaking images across the inner Solar System. Pictured here in 2004, Opportunity looks opposite the Sun into Endurance Crater and sees its own shadow. Two wheels are visible on the lower left and right, while the floor and walls of the unusual crater are visible in the background. Caught in a dust storm in 2018, Opportunity stopped responding, and NASA stopped trying to contact it in 2019 and declared the ground-breaking mission, originally planned for only 92 days, complete.

NASA Astronomy Picture of the Day:

Only two days after the February New Moon's annular eclipse of the Sun, a slender lunar crescent poses above the western horizon after sunset in this wintry twilight skyscape. Its nightside faintly illuminated by earthshine, the young Moon is joined by three bright planets in the mostly clear, early evening skies above the village of Kirazli, Turkiye. Inner planet Venus appears closest to the horizon. Near the beginning of its 2026 performance as planet Earth's evening star, brilliant Venus is seen through the warm sunset glare near picture center. Straight above Venus, innermost planet Mercury is easy to spot as it stands remarkably high above the horizon even as the twilight sky is growing dark. Outer planet Saturn, most distant of the naked-eye planets, is found just left of the Moon's sunlit crescent.

NASA Astronomy Picture of the Day:

"A ghost in the Milky Way…” says Christian Bertincourt, the astrophotographer behind this striking image of Barnard 93 (B93). The 93rd entry in Barnard’s Catalogue of Dark Nebulae, B93 lies within the Small Sagittarius Star Cloud (Messier 24), where its darkness stands in stark contrast to bright stars and gas in the background. In some ways, B93 is really like a ghost, because it contains gas and dust that was dispersed by the deaths of stars, like supernovas. B93 appears as a dark void not because it is empty, but because its dust blocks the light emitted by more distant stars and glowing gas. Like other dark nebulas, some gas from B93, if dense and massive enough, will eventually gravitationally condense to form new stars. If so, then once these stars ignite, B93 will transform from a dark ghost into a brilliant cradle of newborn stars.

Horace - (65 BC –8 BC) - Roman lyric poet Quintus Horatius Flaccus commonly  known in the English-speaking world as Horace., he is considered one of the greatest Roman lyric poets. He is particularly known for his Odes, a collection of short poems that explore themes of love, friendship, philosophy, and politics. Horace's work was done during this period, known as the Golden Age of Roman literature during the under the reign of Augustus. More

NASA Astronomy Picture of the Day:

Grand spiral galaxies often seem to get all the glory, flaunting their young, bright, blue star clusters in beautiful, symmetric spiral arms. But small, irregular galaxies form stars too. In fact, dwarf galaxy IC 2574 shows clear evidence of intense star forming activity in its telltale reddish regions of glowing hydrogen gas. Just as in spiral galaxies, the turbulent star-forming regions in IC 2574 are churned by stellar winds and supernova explosions spewing material into the galaxy's interstellar medium and triggering further star formation. A mere 12 million light-years distant, IC 2574 is part of the M81 group of galaxies, seen toward the northern constellation Ursa Major. Also known as Coddington's Nebula, the faint but intriguing island universe is about 50,000 light-years across, discovered by American astronomer Edwin Coddington in 1898.

                   Sonnet

Oh for a poet—for a beacon bright
To rift this changeless glimmer of dead gray; 
To spirit back the Muses, long astray,
And flush Parnassus with a newer light;
To put these little sonnet-men to flight
Who fashion, in a shrewd mechanic way, 
Songs without souls, that flicker for a day, 
To vanish in irrevocable night,

What does it mean, this barren age of ours? 
Here are the men, the women, and the flowers, 
The seasons, and the sunset, as before.
What does it mean? Shall there not one arise 
To wrench one banner from the western skies, 
And mark it with his name forevermore?

Edwin Arlington Robinson (1869 – 1935) was an American poet born in Maine. Robinson won the Pulitzer Prize for Poetry on three occasions and was nominated for the Nobel Prize in Literature four times.

NASA Astronomy Picture of the Day:

Cradled in red-glowing hydrogen gas, stars are being born in Orion. These stellar nurseries lie at the edge of the giant Orion molecular cloud complex, some 1,500 light-years away. This detailed view spans about 12 degrees across the center of the well-known constellation, with the Great Orion Nebula, the closest large star-forming region, visible toward the lower right. The deep mosaic also includes, near the top center, the Flame Nebula and the Horsehead Nebula. Image data acquired with a hydrogen-alpha filter adds other remarkable features to this wide-angle cosmic vista: pervasive tendrils of energized atomic hydrogen gas and portions of the surrounding Barnard's Loop. While the Orion Nebula and many stars in Orion are easy to see with the unaided eye, emission from the extensive interstellar gas is faint and much harder to record, even in telescopic views of the nebula-rich complex.
