NGC 104 LRBB70smallAPOD.jpg
47 Tucanae is the second brightest globular cluster after Omega Centauri, and telescopically reveals about ten thousand stars, many appearing within a small dense central core. The cluster may contain an intermediate-mass black hole.

Everything you ever wanted to know about this cluster here: 47 Tucanae

The Great Carina Nebula in H-alpha and O[3] Mapped Colors
NGC3372-DWillasch-1.jpg
This overwhelming Emission Nebula is surely the crown of the Carina Milky Way, if not of the whole Southern Sky. The central part of the nebula is located around the Keyhole Nebula and the Giant Star Eta Carinae in the center of the image.

This shot was captured in the Sierra Nevada National Park, in Granada. A mountain chain in the south of the Iberian Peninsula with peaks above 11,000 feet. The abandoned astronomical observatory of Mojón del Trigo (1902) also appears in the background.

These are some shots taken early this morning (April 06) of the AZURE (Auroral Zone Upwelling Rocket Experiment) rocket launch from Andøya Space Center, Norway. I was a scientist working with this launch and took these from nearby Alomar Observatory. Briefly, the AZURE mission used sounding rockets to release these glowing tracer clouds in the upper atmosphere, from around 100km to up to 250km altitude. Observers at the ground sites (like me) then use optical instruments - which are mostly off-the-shelf dSLR cameras - to track the way the clouds move over the next ~30 minutes. This allows investigators to learn about the winds and magnetic fields at these altitudes.

As a bonus, it also looks spectacular.

THE STAR PARADE
This may seem like a simple picture, but in fact, besides counting on luck, it had to be very well planned.
Planned to catch the precise moment the HD 168233, of magnitude +9.25, was exactly between the ring of Saturn and the globe of the planet. A little before, or shortly after, she would be covered up. . .
To count on luck, so that the atmospheric conditions would allow the capture at the exact moment. . .
The truth is, luck always provides persistence, and persistence can bring us unusual results.

Mars this year gave a real Show. . .
That being so, I could not fail to register it.
This composition, made with an approximate interval of 10 to 15 days between the photos, starts on July 31 when the planet reaches the largest apparent diameter (24.3 "arc) and ends on December 5 when it was with only 8.9 "of arc.
Three things are quite evident in such a work: first, the sharp reduction of the diameter as the planet departs; secondly, the phase decrease as it approaches the quadrature and, finally, the marked reduction of the Southern Polar Cap, which, in the last photo, is reduced to a small point. . .
Like Nike the Greek Goddess of Victory, the source of my inspiration, Mars has won my expectations, won my longings and brought me the feeling of having witnessed an unforgettable epic event. . .
"The planetary arrangement was inspired in the shape of the wing of the Nike Goddess"
