These cosmic clouds have blossomed 1,300 light-years away in the fertile starfields of the constellation Cepheus. Called the Iris Nebula, NGC 7023 is not the only nebula to evoke the imagery of flowers. Still, this deep telescopic image shows off the Iris Nebula's range of colors and symmetries embedded in surrounding fields of interstellar dust. Within the Iris itself, dusty nebular material surrounds a hot, young star. The dominant color of the brighter reflection nebula is blue, characteristic of dust grains reflecting starlight. Central filaments of the reflection nebula glow with a faint reddish photoluminescence as some dust grains effectively convert the star's invisible ultraviolet radiation to visible red light. Infrared observations indicate that this nebula contains complex carbon molecules known as PAHs. The dusty blue petals of the Iris Nebula span about six light-years.

The dark-floored, 95 kilometer wide crater Plato and sunlit peaks of the lunar Alps (Montes Alpes) are highlighted in this this sharp telescopic snapshot of the Moon's surface. While the Alps of planet Earth were uplifted over millions of years as continental plates slowly collided, the lunar Alps were likely formed by a sudden collision that created the giant impact basin known as the Mare Imbrium or Sea of Rains. The mare's generally smooth, lava-flooded floor is seen below the bordering mountain range. The prominent straight feature cutting through the mountains is the lunar Alpine Valley (Vallis Alpes). Joining the Mare Imbrium and northern Mare Frigoris (Sea of Cold) the valley extends toward the upper right, about 160 kilometers long and up to 10 kilometers wide. Of course, the large, bright lunar alpine mountain below and right of Plato crater is named Mont Blanc. Lacking an atmosphere, not to mention snow, the lunar Alps are probably not an ideal location for a winter vacation. Still, a 150 pound skier would weigh a mere 25 pounds on the Moon.

Yellowbar angelfish (Pomacanthus maculosus), Ras Muhammad National Park, Red Sea, Egypt. This marine angelfish is distributed throughout the Persian Gulf, the northwestern Indian Ocean, and the Red Sea south to 19°S. In 2009 it was recorded off the coast of Lebanon in the eastern Mediterranean, probably as a result of Lessepsian migration from the Red Sea through the Suez Canal. Pomacanthus maculosus is found at depths of between 4 and 50 metres (13 and 164 ft). It is a solitary species that lives in sheltered areas, often where there is a mixture of coral and silt. Their diet is dominated by sea sponges and tunicates, although other invertebrates will be eaten opportunistically. The females attain sexual maturity when the reach around 5.5 years of age and a total length of 21.6 centimetres (8.5 in). The maximum longevity is thought to be 36 years old. They are protogynous hermaphrodites and the older females can change sex to become males when there is a shortage of males. The larvae are planktonic. The yellowbar angelfish is occasionally collected for the aquarium trade and in some parts of the Persian Gulf it has been recorded in fish markets.

Look, in the early light, 
   Down to the infinite 
   Depths at the deep grass-roots; 
  Where the sun shoots 
In golden veins, as looking through 
   A dear pool one sees it do; 
   Where campion drifts 
Its bladders, iris-brinded, through the rifts 
  Of rising, falling seed
   That the winds lightly scour—
Down to the matted earth where over 
   And over again crow’s-foot and clover
  And pink bindweed
  Dimly, steadily flower.

Michael Field was a pseudonym used for the poetry and verse drama of the English authors Katherine Harris Bradley (1846 – 1914) and her niece and ward Edith Emma Cooper (1862 – 1913). As Field they wrote around 40 works together, and a long journal Works and Days. Their intention was to keep the pen-name secret, but it became public knowledge, not long after they had confided in their friend Robert Browning
