In their paper published in Frontiers of Physics, Franco Vazza (astrophysicist at the University of Bologna) and Alberto Feletti (neurosurgeon at the University of Verona) investigated the similarities between two of the most challenging and complex systems in nature: the cosmic network of galaxies and the network of neuronal cells in the human brain.
It may be from a magnetar born in a neutron star crash.
What baffles modern viewers about the Nazca Lines is their scale. These sprawling geoglyphs are so large that they are difficult to perceive from the ground. Their incomprehensible dimensions have led some to peddle racist conspiracy theories that they were created by aliens (as if it were easier to believe in aliens than to attribute these feats to Indigenous American societies). The key to understanding one recently rediscovered geoglyph, however, lies in much smaller works of art.
David Tholen, an astronomer at the University of Hawaii, recently reported on the status of asteroid Apophis during a virtual meeting of the American Astronomical Society’s Division for Planetary Sciences. During his presentation, he outlined research he and his team conducted regarding the path of the asteroid and the likelihood that it will strike Earth.

Lasers will help older fighters stay alive while flying the deadly skies.
Just as regions across the US have their own urban legends, many have controversial conspiracy theories as well.
Dust storms triggered the loss of massive amounts of water from high in Mars’ atmosphere, according to new analysis of data collected by NASA’s MAVEN spacecraft. For the first time, water has been tracked all the way into Mars’ upper atmosphere, say the authors of a new paper appearing in the journal Science.
