ESA’s Million-Year Time Machine
Imagine that we could take control of #time and run it backwards and forwards to see #how the #MilkyWay evolved in the #past and how it will do so in the #future. Well, that’s what the ESA Gaia space observatory does by mapping almost every visible star in the Milky Way. This is how one small satellite is giving us an insight into the past and the future.

The first panorama I ever shot. I chose this arctic nightscape as my scene because why on earth wouldn't I!?
The Milky Way, Andromeda Galaxy, Venus, airglow, Pleiades, Zodiacal light (sunlight scattered by interplanetary dust), aurora and an iridium flare. :) [+]
#Airglow Sky Over #France by #JulienLooten
This unusual sky was both familiar and unfamiliar. The photographer's mission was to capture the arch of the familiar central band of our #MilkyWay #Galaxy over a picturesque medieval manor. The surprise was that on this January evening, the foreground sky was found glowing in a beautiful but unfamiliar manner. The striped bands are called airglow and they result from air high in Earth's atmosphere being excited by the Sun's light and emitting a faint light of its own. The bands cross the entire sky -- their curved appearance is due to the extremely wide angle of the camera lens. In the foreground lies Château de Losse in southwest France. Other familiar sky delights dot the distant background including the bright white #star #Sirius, the orange planet Mars, the blue #Pleiades star cluster, the red California Nebula, and, on the far right, the extended #Andromeda Galaxy. The initial mission was also successful: across the top of the frame is the arching band of our Milky Way.

#Photographers Jo Scott and Jake Scott-Gardner worked together to capture this #photograph. They achieved this 70 picture panorama using a Nikon D810 camera with a 35mm lens for 20 second exposures at an aperture of f/1.4 and ISO 8000. They focus stacked the foreground, since they used a wide aperture. Both the foreground and background were photographed at the same time because the camera settings and location provided enough light to do so. Their general post processing includes correcting lens distortion, focus stacking the foreground images, stitching all of the images together, masking any out of focus sections, and finally adding edits including contrast and saturation.
A new study has revealed the true shape of the diffuse cloud of stars surrounding the disk of our galaxy. For decades, astronomers have thought that this cloud of stars -- called the stellar halo -- was largely spherical, like a beach ball. Now a new model based on modern observations shows the stellar halo is oblong and tilted, much like a football that has just been kicked.
