Galactic treasure chest

Galaxies abound in this spectacular Hubble image; spiral arms swirl in all colours and orientations, and fuzzy ellipticals can be seen speckled across the frame as softly glowing smudges on the sky. Each visible speck of a galaxy is home to countless stars. A few stars closer to home shine brightly in the foreground, while a massive galaxy cluster nestles at the very centre of the image; an immense collection of maybe thousands of galaxies, all held together by the relentless force of gravity.

Galaxy clusters are some of the most interesting objects in the cosmos. They are the nodes of the cosmic web that permeates the entire Universe — to study them is to study the organisation of matter on the grandest of scales. Not only are galaxy clusters ideal subjects for the study of dark matter and dark energy, but they also allow the study of farther-flung galaxies. Their immense gravitational influence means they distort the spacetime around them, causing them to act like giant zoom lenses. The light of background galaxies is warped and magnified as it passes through the galaxy cluster, allowing astronomers insight into the distant — and therefore early — Universe.

This image was taken by Hubble’s Advanced Camera for Surveys and Wide-Field Camera 3 as part of an observing programme called RELICS (Reionization Lensing Cluster Survey). RELICS imaged 41 massive galaxy clusters with the aim of finding the brightest distant galaxies for the forthcoming NASA/ESA/CSA James Webb Space Telescope (JWST) to study.

This new publication, „Operation Torch: The American Amphibious Assault on French Morocco, 1942„: the story of breaking away from established U.S. military doctrine and winning.

Operation Torch: The American Amphibious Assault on French Morocco, 1942

Operation Torch: The American Amphibious Assault on French Morocco, 1942 Operation Torch. the Allied invasion of North Africa in World War II, set the United States Army firmly on the course it was to follow in the war and decisively ended strategic debates on how the war should be fought. Commencing 8 November 1942, Torch committed the Army to a Mediterranean strategy for at least a year, prejudicing the buildup of forces in the United Kingdom and abrogating any chance of a major attack on Europe across the English Channel in 1943.

The strategic issues surrounding President Franklin D. Roosevelt’s highly political decision that American troops had to go into action against the Germans in 1942 have been thoroughly and thoughtfully discussed.

The Army entered World War II with established doctrine for command and staff planning of joint operations, procedures the service virtually ignored from the start of the planning for Torch.
