We’re celebrating Star Wars Day with this mesmerizing photo from Natural Bridges National Monument in Utah. Natural Bridges has one of the darkest night skies in the U.S. – it’s possible to see up to 15,000 stars throughout the night. Pictured here is the Milky Way above Owachomo Bridge (one of the park’s three natural bridges) by Manish Mamtani, www.sharetheexperience.org.
Switch to the invisible wavelengths of the far-infrared and the Milky Way’s river of stars disappears to reveal tendrils of cold dust. Shown here, in this image from Japan’s Akari space observatory, are the central regions of the constellation Cygnus, and it can be seen that the Milky Way displays a rich stock of dust.

The mystical-looking image is part of Akari’s recently released all-sky survey. The mission observed more than 99% of the entire sky over a period of 16 months. Akari was a Japan Aerospace Exploration Agency (JAXA) project with European Space Agency’s participation.
Last week, amateur Polish photographer
Bartosz Wojczyński combined an amazing 32,000 images to create a super
high-resolution picture of the moon. It took only 28 minutes to take the
photos from his balcony in Piekary Śląskie, but the total file size
for the photos was a whopping 73.5 gigabytes. Wojczyński spent 5-6 hours
combining the images.
Moon photography is an old art. John
William Draper was the first person to take a picture of the full moon,
175 years ago. While Wojczyński spent $3500 on his equipment, Draper
used a simple daguerreotype camera to capture his subject. You can
compare Draper’s photo with Wojczyński’s photo to see how far we’ve come.
And while Draper’s photo was black and
white, Wojczyński used advanced image acquisition and processing
techniques to color the photo. He told PetaPixel that he had to map
violet and infrared images of the moon to blue and red channels in the
final shot. Bored Panda
Appearing like a winged creature poised on a pedestal, this object is actually a billowing tower of cold gas and dust rising from a stellar nursery called the Eagle Nebula. The soaring tower is 9.5 light-years high, about twice the distance from our Sun to the next nearest star
The sparkling centerpiece of Hubble’s anniversary fireworks is a giant cluster of about 3,000 stars called Westerlund 2, named for Swedish astronomer Bengt Westerlund who discovered the grouping in the 1960s. The cluster resides in a raucous stellar breeding ground known as Gum 29, located 20,000 light-years away from Earth in the constellation Carina, NASA/HUBBLE
With its helical appearance resembling a snail’s shell, this reflection nebula seems to spiral out from a luminous central star in this NASA/ESA Hubble Space Telescope image.
The star in the centre, known as V1331 Cyg and located in the dark cloud LDN 981 — or, more commonly, Lynds 981 — had previously been defined as a T Tauri star. A T Tauri is a young star — or Young Stellar Object — that is starting to contract to become a main sequence star similar to the Sun.
What makes V1331Cyg special is the fact that we look almost exactly at one of its poles. Usually, the view of a young star is obscured by the dust from the circumstellar disc and the envelope that surround it. However, with V1331Cyg we are actually looking in the exact direction of a jet driven by the star that is clearing the dust and giving us this magnificent view.

The Heart Nebula, an emission nebula in the constellation of Cassiopeia 7,500 lightyears away. Formed by the plasma of ionized hydrogen and free electrons, this nebula’s red appearance is the result of radiation emitted by a group of stars in its center known as Melotte 15.
