Magnetic stripes (magstripes) are in fact magnetic. What’s so cool about magstripes is that while the magnetic strips inside are weak, they’re still strong enough to attract small ferrous particles and wide enough that we can fully extract all data from a magstripe or credit card with the naked eye.

Rosatom has released previously classified footage of the largest bomb to ever be detonated, Tsar Bomba.
With a yield of 50 megatons (50 million tons), equal to around 3,800 Hiroshima bombs, the weapon was set off over Novaya Zemlya on October 30, 1961

Bonus: The Moonraker (James Bond) score works great even if the obvious (and maybe overused) choice would have been Holst’s track.
NASA’s Juno spacecraft captured a unique time-lapse movie of the Galilean satellites in motion about Jupiter. The movie begins on June 12th with Juno 10 million miles from Jupiter, and ends on June 29th, 3 million miles distant. The innermost moon is volcanic Io; next in line is the ice-crusted ocean world Europa, followed by massive Ganymede, and finally, heavily cratered Callisto. Galileo observed these moons to change position with respect to Jupiter over the course of a few nights. From this observation he realized that the moons were orbiting mighty Jupiter, a truth that forever changed humanity’s understanding of our place in the cosmos. Earth was not the center of the Universe. For the first time in history, we look upon these moons as they orbit Jupiter and share in Galileo’s revelation. This is the motion of nature’s harmony.
