A third of galaxies clusters unobserved
As many as a third of galaxies clusters have previously been unobserved. Not all the clusters look the same in the optical range. Some clusters have fewer and less luminous galaxies, more loosely packed, than conventional clusters and their appearance is similar to ordinary regions of the sky.
Earth’s exposed continental crust comprises TTG
Earth’s exposed continental crust comprises TTG (tonalite-trondhjemite-granodiorite) rocks that resemble the crust of modern subduction settings. These rocks were derived from an earlier generation of basaltic rocks, incompatible with modern plate tectonics. The TTG were formed near the base of a thick plateau-like basaltic crust. Subduction was not required at that time.
A ring-shaped device changes symetry and polarization of light
In a ring-shaped device light loses its time-reversal symetry and changes its polarization. Inside the ring light waves turn circles and resonate with one another.
About geocorona, a part of Earth’s exosphere
The geocorona, part of the exosphere of the Earth, a tenuous cloud of neutral hydrogen, extends out to as much as 630 000 km. It glows in far-ultraviolet light. Space telescopes observing the sky need to adjust their Lyman-alpha baselines for more accurate mapping.
Hidden galaxies in a tiny corner of the sky…
The Low Frequency Array (LOFAR) has added 325 694 new points of radio waves in a tiny corner of the sky. Around 70% can be linked with hidden galaxies.

(73aH*) : August 6th is the anniversary of the atomic bomb explosion on Hiroshima in 1945.
