Researchers have taught an artificial intelligence program used to recognize faces on Facebook to identify galaxies in deep space.

The result is an AI bot named ClaRAN that scans images taken by radio telescopes.

Its job is to spot radio galaxies – galaxies that emit powerful radio jets from supermassive black holes at their centers.

Vitamins are the building blocks that keep our bodies running; they help build muscle and bone, capture energy, heal wounds and more. Today, TED-Ed wants to bring you your daily value and introduce you to the members of the team!

Vitamin A helps make white blood cells, shape bones, and improves vision. 

The B Vitamins are a complex bunch - some of them make up co-enzymes, who help enzymes release energy from food. Others help the body to use that energy.

From Vitamin C, we get the ability to fight infection and make collagen, a kind of tissue that forms bones and teeth, and heals wounds.

Vitamin D gathers calcium and phosphorous so we can make bones.

Vitamin E works as an antioxidant, getting rid of elements in the body that can damage cells.

Finally, Vitamin K helps us make the proteins that clot blood.

Without this Vitamin Variety, humans face deficiencies that cause a range of problems. On the other hand, too much of any vitamin can cause toxicity in the body. In reality, it’s all about getting the balance right, and hitting that vitamin jackpot! Thanks, Team Vitamin!

10 tricks you didn’t know you could do with your food.

Nicolaus Copernicus

Nicolaus Copernicus (19 February 1473 – 24 May 1543) was a Renaissance-era mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe, likely independently of Aristarchus of Samos, who had formulated such a model some eighteen centuries earlier.

The publication of Copernicus’ model in his book De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just before his death in 1543, was a major event in the history of science, triggering the Copernican Revolution and making an important contribution to the Scientific Revolution.

Copernicus was born and died in Royal Prussia, a region that had been part of the Kingdom of Poland since 1466. A polyglot and polymath, he obtained a doctorate in canon law and was also a mathematician, astronomer, physician, classics scholar, translator, governor, diplomat, and economist. In 1517 he derived a quantity theory of money – a key concept in economics – and in 1519 he formulated an economic principle that later came to be called Gresham’s law.

Parker Solar Probe Breaks Record, Becomes Closest Spacecraft to Sun

Parker Solar Probe now holds the record for closest approach to the Sun by a human-made object. The spacecraft passed the current record of 26.55 million miles from the Sun’s surface on Oct. 29, 2018, at about 1:04 p.m. EDT, as calculated by the Parker Solar Probe team.

The previous record for closest solar approach was set by the German-American Helios 2 spacecraft in April 1976. As the Parker Solar Probe mission progresses, the spacecraft will repeatedly break its own records, with a final close approach of 3.83 million miles from the Sun’s surface expected in 2024.
