10 IMMENSE THINGS IN SPACE


01 Biggest asteroid 
ceres
950km diameter (average) Discovered in 1801, ceres makes up a third of the total mass of the asteroid belt between mars and Jupiter.

02 Biggest object in our solar system
sun
1,392,000km diameter the yellow dwarf star around which we orbit comprises over 99.8 per cent of the total mass of our solar system.

03 Biggest known planet 
GQ Lup b
30 times the radius of Jupiter this huge exoplanet, detected orbiting a star some 457 light-years from earth, may have a mass up to 36 times that of Jupiter and is fiercely hot – possibly 2,650 kelvin.

04 Largest structure in the universe
Huge Large Quasar Group (Huge-LQG)
4 billion light-years across in 2013, an international team detected a chain of some 73 quasars stretching so far that its existence challenges the fundamental cosmological Principle.

05 Biggest black hole 
centre of ngc 1277
17 billion solar mass this supermassive black hole, at the centre of the nGc 1277 galaxy 220 million light-years away, has a mass 17 billion times greater than our sun – itself about two nonillion kg.

06 Largest galaxy
ic 1101
Six million light-years across this supergiant elliptical galaxy, discovered in 1790 by William Herschel, at the centre of the Abell 2029 cluster is about one billion light-years away. our own galaxy, the milky Way, is a mere 100,000 light-years across.

07 Biggest water cloud Around quasar
APM 08279+5255
40 billion times the mass of earth in 2011, researchers discovered a vast cloud of water vapour surrounding a quasar some 12 billion light-years away. the cloud holds enough water to fill the earth’s oceans 140 trillion times over.

08 Biggest comet 
McNaught Visible tail 35° the spacecraft ulysses passed through the tail of this comet in 2007 and detected ionised gas at a distance of 225 million km behind the nucleus. the ‘shocked wind’ behind the comet was larger still, making mcnaught reportedly the largest comet ever discovered.

 09 Biggest nothing 
boötes Void
250 million lightyears across An area of space containing nearly no objects (though a few galaxies are present), this ‘void’ is around 700 million light-years from earth.

10 Biggest star 
Westerlund 1-26
1,530 solar radii measuring distant stars is tricky – determining the edge of the star can be made difficult by solar winds – but the royal Astronomical society believes this red supergiant, which is about 1,000,000,000km across and some 16,000 light-years from earth, is the largest.

Why do different countries use different mains voltages?

Why do different countries use different mains voltages? the biggest disparity is between the usA on 110V and most of the rest of the world on 230V. America’s lower voltage goes all the way back to thomas edison, who introduced direct current (dC) mains electricity at 110V. edison’s rival nikola tesla showed that long power lines transmitted alternating current (AC) more efficiently than dC. His AC approach won out, but he stuck with edison’s 110V. But by the time electrification spread to europe early in the 20th Century, lamps had filaments that could give out more light and handle greater power loads. so the Berliner elektrizitätswerke company in Germany established 230V as the standard.

Ten most dangerous animals in the world.

10 DANGEROUS ANIMALS 10 Poison dart frog (phyllobates terribilis)  Human deaths/year: Unknown living in the rainforest of colombia, this frog’s skin is coated with enough batrachotoxins to kill at least ten men. 09 Box jellyfish (Chironex fleckeri) human deaths: at least 60 since 1883 each of the sea wasp’s tentacles is armed with about 5000 stinging cells. 08 sloth bear (Melursus ursinus)  Human deaths/year: <2 like other bear species, sloth bears don’t predate humans, but chance encounters can result in deaths. 07 Great white shark (carcharodon carcharias)  Human deaths/year: <30 unprovoked shark attacks on humans are extremely rare – and fatalities even rarer. Great white, tiger and bull sharks are responsible for most. 06 lion (panthera leo) Human deaths/year: ≤100 lion attacks on humans often occur during harvests, but rare outbreaks of mass ‘maneating’ also occur. 05 African elephant (Loxodonta africana)  Human deaths...

Do video games change the brain?

Do video games affect behaviour? Video games are likely able to affect the way we behave in a number of ways. For instance, there’s concern about whether violence in games makes young people more violent. It’s not uncommon for news outlets to blame games every time a crime happens, but how true is that claim? This is controversial even within the scientific community. Yes, exposure to violence seems to affect the brain, but studies have also found that we’re good at distinguishing between real and virtual violence, and aggressive behaviour is better explained by other, mainly socio-economic factors. Numerous studies about the effects of games on the brain had been published, but all that information had not been put together until now. How did you review the research?  We gathered all scientific articles to date and compared results. In total, we found 116 experiments, the first from the 1980s. Many compared regular video game players with people who had never played; other...
