Midnight at the Oasis

ESO/F. Char

Tuesday, April 2, 2013: Stars in the southern night sky appear to trail over the Residencia “hotel” at ESO’s Paranal Observatory in Chile. A 30-minute exposure reveals the observed movement of the stars due to the rotation of the Earth. In the center lies the apparently still point of the south celestial pole. On the left, and at the top of the image, float the blurred Large and Small Magellanic Clouds, neighboring galaxies of the Milky Way. The dark glass dome below the circling stars makes up part of the roof of the Residencia building. Scientists and engineers working at the observatory have used this partially subterranean construction since 2002. To combat the extreme sun and low humidity at high altitude, the building offers an artificial oasis, with a small garden, a swimming pool that humidifies the air, a lounge, a dining room, and other recreational facilities.

Into the Labyrinth

ESA/DLR/FU Berlin (G. Neukum); Image mosaic assembled by Bill Dunford

Wednesday, April 3, 2013: This mosaic shows part of the Noctis Labyrinthus region, ‘Labyrinth of the Night,’ on Mars. The region lies west of the immense gash of Valles Marineris. Scientists think the uneven region may have developed by volcanic activity in the neighboring region of Tharsis, stretching the Martian crust and fracturing it. Bill Dunford composed the mosaic using scenes available in the Mars Express image archive.

Wednesday, April 10, 2013: Hook-shaped J082354.96+280v621.6, or J082354.96 for short, is a starburst galaxy. The unusually high rate of star formation occurring within it gives rise to the starburst name.
