Big Dipper to Southern Cross
Image Credit & Copyright: Petr Horálek

Explanation: Welcome to an equatorial night. This remarkable 24 frame night skyscape was captured from Maba Beach on the Indonesian island of Halmahera during the evening of March 4. Seen from a mere 0.7 degrees northern latitude, both famous northern and southern asterisms and navigational aids lie within the panoramic view. The Big Dipper is on the far left and Southern Cross at the far right. Beyond the fading campfire on that night a yellow-orange celestial triangle is set by Mars, Antares, and Saturn. It stands above the rising central Milky Way, or "Miett" in the local Maba language. Of course, you can follow the pole pointing stars in the cup of the Big Dipper or body of theSouthern Cross to the north and south celestial poles. Both lie just at the horizon in the view from the island's equatorial beach.

NGC 6188 and NGC 6164

Explanation: Fantastic shapes lurk in clouds of glowing gas in the giant star forming region NGC 6188. The emission nebula is found about 4,000 light years away near the edge of a large molecular cloud unseen at visible wavelengths, in the southern constellation Ara. Massive, young stars of the embedded Ara OB1 association were formed in that region only a few million years ago, sculpting the dark shapes and powering the nebular glow with stellar winds and intense ultraviolet radiation. The recent star formation itself was likely triggered by winds and supernova explosions, from previous generations of massive stars, that swept up and compressed the molecular gas. Joining NGC 6188 on this cosmic canvas, visible toward the lower right, is rare emission nebula NGC 6164, also created by one of the region's massive O-type stars. Similar in appearance to many planetary nebulae, NGC 6164's striking, symmetric gaseous shroud and faint halo surround its bright central star near the bottom edge. The impressively wide field of view spans over 3 degrees (six full Moons), corresponding to over 200 light years at the estimated distance of NGC 6188. Three image sets have been included in the featured composite.

Considerada o coração da cidade, a Avenida dos Aliados é a avenida mais bonita da cidade. Com seus edifícios imponentes, marcas de uma época em que as grandes instituições eram ali sediadas, esta avenida tem mesmo um "ar" muito europeu. É a partir da Av. dos Aliados que avistamos a sede da Câmara Municipal do Porto, e é nesta avenida onde muita coisa acontece, desde manifestações, comemorações. festas e apresentações culturais. Aprecie os detalhes da arquitetura desta avenida. Impressionam...

Astronomy picture of the day - 2016 March 29 - NASA's Curiosity Rover at Namib Dune (360 View)

Explanation: Point or tilt to see a spectacular view of Mars visible to the Curiosity rover last December. In the foreground, part of Curiosity itself is visible, including its dusty sundial. Starting about seven meters back, the robotic rover is seen posing in front of a 5-meter tall dark sand dune named Namib, one of many dunes that span Bagnold field. Further in the distance is the summit of Mt. Sharp, the 5.5-kilometer peak at the center of 150-km wide Gale crater, the crater where Curiosity landed a few years ago. The featured composite spans a full 360-degrees around by combining several images taken on the same day, while the result has been color adjusted to mimic Earth lighting. Mostrecently, Curiosity is crossing the rocky and uneven Naukluft Plateau as it continues to make its way around and up Mt. Sharp.
