BLOCKBUSTERS 2018: The 15 Most Anticipated Movies of 2018



April 2017 Solar Flares - UNIVERSE


The sun emitted a trio of mid-level solar flares on April 2-3, 2017. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured images of the three events.

The Holographic Principle - PHYSICS


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 derives from the idea that the Planck length, the length scale where quantum mechanics begins to dominate classical gravity, is one side of an area that can hold only about one bit of information. The limit was first postulated by physicist Gerard 't Hooft in 1993. It can arise from generalizations from seemingly distant speculation that the information held by a black hole is determined not by its enclosed volume but by the surface area of its event horizon. The term "holographic" arises from a hologram analogy where three-dimension images are created by projecting light though a flat screen. Beware, other people looking at the featured image may not claim to see 3 x 1065 bits -- they might claim to see a teapot.

PIRATES OF THE CARIBBEAN 5 New TV Spots (2017)



Hercules Beetle pupa - BIODIVERSITY


Hercules beetles are a form of rhinoceros beetle that can reach more than 17cm long. They transform larvae to a pupa stage.


Once hatched from its egg, the larva spends up to two years tunneling/eating rotting wood; the larva looks like a large white caterpillar.

Once they have stored enough energy they will turn into a hard shell and morph into the beetle, when the beetle is ready to come out they will moult (shed) their shell and emerge an adult.

The footage was shared online by Ziya Tong, the host of a TV nature program in Canada called Daily Planet.

Two Million Stars on the Move - UNIVERSE


If you could watch the night sky for one million years -- how would it change? Besides local effects caused by the Earth's spin and the reorientation of the Earth's spin axis, the stars themselves will move. Combining positional data of unprecedented accuracy for two-million stars taken over years by ESA's Earth-orbiting Hipparcos (now defunct) and Gaia satellites, a future extrapolation of star movements was made over millions years.

Many stars make only small angular adjustments, but some stars -- typically those nearby -- will zip across the sky. Once familiar constellations and asterisms will become unrecognizable as the bright stars that formed them move around. Not shown  are many local nebulas that will surely dissipate while new ones will likely form in different places. Perhaps reassuringly, future Earth inhabitants will still be able to recognize the central band of our Milky Way Galaxy.
