Harry Potter and the Moons of Jupiter

Written by K.A.Cassimally

It is inrepparttar latest Harry Potter novel, Harry Potter andrepparttar 127671 Order ofrepparttar 127672 Phoenix, that readers getrepparttar 127673 confirmation thatrepparttar 127674 ‘Boy who lived’ is indeed interested in a science that even some Muggles are good at: Astronomy,repparttar 127675 study of celestial objects, of space and ofrepparttar 127676 physical universe as a whole. Mayberepparttar 127677 awful Dursleys did do some good things with Harry when they letrepparttar 127678 wizard, who did not yet know he was one, learn Astronomy.

At Hogwards School of Witchcraft and Wizardry though, Harry and his two best friends, Ron and Hermione, seemed to be going on more withrepparttar 127679 giant ofrepparttar 127680 giants: Jupiter but to be more precise with its moons.

But unluckily forrepparttar 127681 wizards and witches, Astronomy was making life difficult. As Harry and his friends would be sitting for their O.W.L.S (Ordinary Wizarding Level) atrepparttar 127682 end ofrepparttar 127683 year, they were bombarded with homework. This was fortunately corrected by Hermione before being actually handed torepparttar 127684 teachers. And believe me, this was a good thing too as both Harry and Ron were making terrible mistakes. If it were not for Hermione, both boys would be getting a ‘D’ standing for Dreadful onrepparttar 127685 top corner of their parchment rolls. An would be: ‘“Harry, you must have misheard Professor Sinistra,” says Hermione, “Europa’s covered in ice not mice!”’

Europa as you might have guessed is way too cold for mice. Spacecrafts have taken photos of this natural satellite and Europa does look lifeless.

If you are a Harry Potter fan though, you may well say that Harry went on Europa by magic and then saw living organisms there. Well coming to think of it, maybe he did find life on Europa if of course he ever went there.

This is because below Europa’s ice coating, scientists think that there may well be a big ocean of liquid water. The biggest ocean inrepparttar 127686 Solar System in fact and that says something. Here on Earth, life and water appear to go together. So it is logical to think that there may be life in that ocean of Europa, is it not? Of course life inrepparttar 127687 form of microbes or some sort of alien fish is expected. And maybe swimming mice!

Asteroid Attack

Written by K.A.Cassimally

Earth, ‘our mother planet’, is being attacked everyday by about 25 tons of dust and sand-sized particles. An asteroid,repparttar size of a small car, hits Earth’s atmosphere about once in every year.

Fortunately she knows how to defend herself. When that small car-sized asteroid enters her atmosphere, she burnsrepparttar 127670 asteroid up beforerepparttar 127671 latter touches her surface. So no damage is done.

But what exactly are asteroids? Asteroids are fragments fromrepparttar 127672 formation ofrepparttar 127673 Solar System some 4.6 billion years ago. Fortunately, most asteroids are found inrepparttar 127674 Asteroid Belt found betweenrepparttar 127675 planets Mars and Jupiter,repparttar 127676 gas giant. Scientists think that asteroids found inrepparttar 127677 belt can be as big as 940 km across.

Like everybody though, Earth cannot cope with each and every one ofrepparttar 127678 asteroids.

If an asteroid has managed not to be completely burned up while sprinting into Earth’s atmosphere, then ???? Scientists think thatrepparttar 127679 collision would cause local damage torepparttar 127680 surrounding area.

If that same asteroid however measures more than 1 km across when it touches Earth’s surface, disaster is on its way. Scientists believe that this impact could have worldwide effects. Man however is helping or trying to help our mother Earth.

Astronomers are now observing and tracking asteroids, which are at an average distance from Earth to Moon. By immediately tracking potential dangers and learning more about their orbital paths, scientists have more time to study potentially threatening situations. Inrepparttar 127681 next few years, NASA hopes to discover more than 90% of all Earth’s threatening objects larger than 1 km across.
