After its spectacular opposition last November, Mars still shone brightly, offering a pleasing addition to shots of the night sky. To wit:
The celestial beacon easily attracted the attention of these two night skygazers who stood still for just a while, but long enough to be captured in the sea and night skyscape from Big Sur, planet Earth. Its central bulge near the southwestern horizon, the Milky Way runs through the scene too, while the long exposure also reveals a faint blue bioluminescence blooming in the waves along Pfeiffer Beach. Now much fainter, Mars can be spotted near the western horizon after sunset, but this month Jupiter is near its closest and brightest, reaching its own opposition on June 10. Night skygazers can spot brilliant Jupiter over southern horizons, glaring next to the stars toward the central Milky Way.

Behold: a long exposure (taken over several nights earlier this year) of the constellation of Orion – not just three stars in a row, rather, a direction in space rich with impressive nebulae. To wit:
Of the many interesting details that have become visible, one that particularly draws the eye is Barnard’s Loop, the bright red orange arc just to the right of the image center. The Rosette Nebula is not the giant orange nebula just to the left of the image center — that is larger but lesser known nebula known as the Meissa Ring. The Rosette Nebula is visible, though: it is the bright orange, blue and white nebula near the image bottom. The bright orange star just left of the frame center is Betelgeuse, while the bright blue star on the upper right is Rigel. About those famous three stars that cross the belt of Orion the Hunter — in this busy frame they can be hard to locate, but a discerning eye will find them just to the right of the image center.

An image taken by the Hubble telescope showing four of the five adjacent galaxies of Stephan’s Quintet in the Pegasus constellation – the first compact galaxy group ever
invited to compete on Strictly discovered. To wit:
Really only four of the five of Stephan’s Quintet are locked in a cosmic tango of repeated close encounters taking place some 300 million light-years away. The odd galaxy out is easy to spot in this recently reprocessed image by the Hubble Space Telescope — the interacting galaxies, NGC 7319, 7318B, 7318A, and 7317 (left to right), have a more dominant yellowish cast. They also tend to have distorted loops and tails, grown under the influence of disruptive gravitational tides. The mostly bluish galaxy, large NGC 7320 on the lower left, is in the foreground at about 40 million light-years distant, and so is not part of the interacting group. Data and modeling indicate that NGC 7318B is a relatively new intruder. A recently-discovered halo of old red stars surrounding Stephan’s Quintet indicate that at least some of these galaxies started tangling over a billion years. Stephan’s Quintet is visible with a moderate sized-telescope toward the constellation of Winged Horse (Pegasus).

Competing to inspire your awe – land and sky. Who ya got? To wit:
The Volcano of Fire (Volcán de Fuego) is seen erupting topped by red-hot, wind-blown ash and with streams of glowing lava running down its side. Lights from neighboring towns are seen through a thin haze below. In the sky, though, the central plane of our Milky Way Galaxy runs diagonally from the upper left, with a fleeting meteor just below, and the trail of a satellite to the upper right. The planet Jupiter also appears toward the upper left, with the bright star Antares just to its right. Much of the land and the sky were captured together in a single, well-timed, 25-second exposure taken in mid-April from the side of Fuego‘s sister volcano Acatenango in Guatemala. The image of the meteor, though, was captured in a similar frame taken about 30 minutes earlier — when the volanic eruption was not as photogenic — and added later digitally.

Star formation is a colourful business – as evidenced by this chromatic cosmic portrait of glowing gas and dark dust near some recently formed stars of NGC 3572 – a cluster near the Carina Nebula. To wit:
Stars from NGC 3572 are visible near the bottom of the image, while the expansive gas cloud above is likely what remains of their formation nebula. The image‘s striking hues were created by featuring specific colors emitted by hydrogen, oxygen, and sulfur, and blending themwith images recorded through broadband filters in red, green, and blue. This nebula near NGC 3572 spans about 100 light years and lies about 9,000 light years away toward the southern constellation of the Ship’s Keel (Carina). Within a few million years the pictured gas will likely disperse, while gravitational encounters will likely disperse the cluster stars over about a billion years.
