What's happened to Comet Lovejoy? In the pictured image, a processed composite, the comet was captured early this month after brightening unexpectedly and sporting a long and intricate ion tail. Remarkably, the typically complex effect of the Sun's wind and magnetic field here caused the middle of Comet Lovejoy's ion tail to resemble the head of a needle. Comet C/2017 E4 (Lovejoy) was discovered only last month by noted comet discoverer Terry Lovejoy.
The comet reached visual magnitude 7 ear [...]
Expedition 51 Commander Peggy Whitson broke the U.S. record today for most cumulative time living in space, surpassing astronaut Jeff Williams’ record of 534 days set during his four spaceflights. She passed Williams’ mark at 1:27 a.m. EDT.
President Donald Trump called the International Space Station Monday morning and congratulated Whitson on her record-breaking career. Whitson and her newest crewmate NASA astronaut Jack Fischer discussed NASA’s research in space and its plans to go t [...]
Trillions have died in the Earth's seas. Calcified shields of the dead already make up the white cliffs of Dover. The battle between ball-shaped light-colored single-celled plants -- phytoplankton called coccolithophores -- and even smaller, diamond-shaped viruses dubbed coccolithoviruses -- has raged for tens of millions of years. To help fight this battle, the coccolithophores create their chalky armor by absorbing carbon dioxide from the atmosphere.
This battle is so epic that coccolithop [...]

Robert Walker is an inventor & programmer for Tune Smithy, Bounce Metronome, Virtual flower, Lissajous 3D, and Activity Timer. I trained as a mathematician originally. Went on to study philosophy then to do post graduate research into set theory [...]
Is this picture worth a thousand words? According to the Holographic Principle, the most information you can get from this image is about 3 x 1065 bits for a normal sized computer monitor. The Holographic Principle, yet unproven, states that there is a maximum amount of information content held by regions adjacent to any surface. Therefore, counter-intuitively, the information content inside a room depends not on the volume of the room but on the area of the bounding walls.
The principle der [...]
