Asteroid Headed For Earth

I have seen at least two movies with the theme of an asteroid heading for Earth. They have both successfully saved the world. But what if it were to really happen?

Scientists have said that if we were to face the prospect of an ELE*, and dealt with the approaching asteroid by blowing it to pieces with nuclear weapons, the effects would be devastating.

The asteroid would, indeed, disintegrate. The pieces would still be highly likely to come into our atmosphere. A large proportion would burn up, but some would still hit the Earth. But worse still, all of the pieces would be radioactive from the nuclear strike, meaning that the entire planet would become radioactive. Not an ideal way to go then.

What they suggest is to send up rockets that would land on the asteroid and fit the asteroid with thrusters, enabling us to alter its course enough to avoid Armageddon.

The second idea is to fit immense sails to it, thus catching the solar winds and again diverting it from Earth.

A third, rather fanciful option if you ask me, is to place a huge magnifying glass between the sun and the asteroid. This would be used to heat the surface of it to a point where it would rupture. This would release gases compressed within the asteroid to vent acting like air escaping a balloon and send it away from us.

Scientific communities have been working on these theories for decades,

Why? Because the possibility of an asteroid is not a question of if, but when. NASA has already stated this.

Poor Old Pluto Gets Demoted

Poor Old Pluto, no longer popular

On August 24th 2006, poor old Pluto was demoted from a planet to a dwarf planet. It was just spinning merrily around the sun in the far reaches of our solar system minding its own business.

Seems even in space you are not safe from annual performance reviews!

Astronomical events for tonight

Just the one. The Moon at aphelion 12.32 till 1.32

Trinity Bomb Test

Today Is Trinity Bomb Test Day

The Trinity test was the code name for the bomb tested for the first time in New Mexico as part of The Manhattan Project. It was the Atomic Bomb. These bombs were later used to bomb Hiroshima and Nagasaki.

Some say that these bombings helped to bring the Second World War to an early close.

The name “Manhattan Project” came abourt simply because that was where the idea of creating such a devastating device first started to evolve.

The bomb was set upon a tower for the test. Scientists and a few top brass observed the test from a distance of 10,000 yards (over 6 miles/9 kms) where the mushroom cloud could be seen to soar 40,000 feet into the air accompanied by a flash of blinding light.

Apollo 11

Today in 1969 saw Apollo 11 depart Earth for the Moon. It was the first mission to successfully see man walk on the moon.

In fact it is still the only mission to have had man walk on the surface of another celestial body.

It was on this day In 1994, scientists observed the Comet Shoemaker-Levy 9 crash into Jupiter. This was the first time anyone had observed two celestial bodies collide.

Today Is Meteor Watch Day

Today Is Meteor Day

On meteor day take the time out to look up at our beautiful Milky Way.

 

Meteors are more common than you might think. Our skies are constantly being bombarded with debris from asteroids. Some are quite large lumps of

meteor day

rubbish, but chances are the meteor, or shooting star, that you see will be, at best, the size of a pea but more likely the size of a grain of sand!

Oddly, there is not much meteor activity in June anywhere in the sky.

 

July sees an active meteor shower: July 27-28, 2018 Delta Aquariids ,visible in both the Southern Hemisphere and the Northern Hemisphere.

 

The maximum rate can reach 15-20 meteors per hour in a dark sky. You will probably need to get out of the city to see them as light pollution is an astronomers enemy, along with rain, clouds etc, etc.
