An interesting model of our solar system’s path as it travels through space in the Milky Way.
Certainly a departure from usual models that show the Sun as a static object, which it certainly isn’t
Side Note: The two images shown above are mere crop outs from ESA’s recent hit: The 9 Billion Pixel Image of 84 Million Stars. These two focus on the bright center of the image for the purpose of highlighting what a peak at 84,000,000 stars looks like.
Astronomers at the European Southern Observatory’s Paranal Observatory in Chile have released a breathtaking new photograph showing the central area of our Milky Way galaxy. The photograph shows a whopping 84 million stars in an image measuring 108500×81500, which contains nearly 9 billion pixels.
It’s actually a composite of thousands of individual photographs shot with the observatory’s VISTA survey telescope, the same camera that captured the amazing 55-hour exposure. Three different infrared filters were used to capture the different details present in the final image.
The VISTA’s camera is sensitive to infrared light, which allows its vision to pierce through much of the space dust that blocks the view of ordinary optical telescope/camera systems.
Behold, the Milky Way, with the magnificent power of 9 billion pixels. The improvements in the imaging of our universe thanks to modern technology are ceaselessly breathtaking.
Femtophotography - A camera that records a trillion frames per second, fast enough to see the passing of a laser pulse through a Coke bottle.
Mesmerizing Pendulum Waves
Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and random motion.
Size of a neutron star compared to New York City. Neutron stars have roughly half a million times more mass than Earth.
