Over 1,000 asteroids threaten Earth!

Asteroids hovering
around Earth |
A few months ago the whole world was in a trance-like shock when it
was reported that the world is on the brink of destruction and the end
will come at any moment. But everyone were relieved as nothing happened
and it is now completely forgotten.
But are you aware that about 1,400 potentially dangerous asteroids
are orbiting alongside our Earth. And mind you any of them is big enough
to wipe out humanity from the face of the world. We know that
apocalyptic asteroids have hit in the past - palaeontologists believe an
asteroid that struck Mexico's Yucatan Peninsula was at least in part
responsible for the mass extinction during the late Cretaceous that
killed off 50 percent of the world's species, dinosaurs among them.
Fortunately, NASA keeps an eye on them for us. But to get NASA's
attention an asteroid has to be "relatively large and close" - at least
460 feet in diameter, and within 4.7 million miles of us. And there are
plenty of space rocks hurtling through the solar system that fit those
criteria.
We saw recently how frighting and destructive these near-earth
objects can be when a meteor exploded over the Chelyabinsk region of
Russia on February 15. An Earth-ending Asteroid would be much, much
worse.
An asteroid about the size of a basketball hits and burns up in
Earth's atmosphere about once a day. Larger ones about the size of a car
do the same a few times a year, disintegrating into stunning fireballs.

the NASA Dawn spacecraft about
3,200 miles above the surface in
Space. NASA is currently tracking
1,400 asteroids orbiting earth which
could destroy it. |
The Near-Earth Object Project Office at Caltech's Jet Propulsion
Laboratory has been monitoring them since 1998, and publishes
information about these and other asteroids and their "impact risk."
It may sound like they are on top of this Earth-ending asteroid
thing, but really, not so much. NASA notes that there is no "government
agency, national or international" tasked with stepping in should an
asteroid decide that Earth is in its way.
That's probably because we haven't found one that's going to end us
yet. "None of these PHAs is a worrisome threat over the next hundred
years, NASA said.
But such events only occur once every several million years, and the
meteorite that, hit the Yucatan in the late Cretaceous, occur only once
every 100 million years.
What ever said if we are expecting the end of the world we'll have to
wait till 2182 when the asteroid RQ36 may hit the world. And the
scientists are already aware of the danger and they say the chance of
destroying life on Earth is 1\1000.
Another Wallenda's amazing feat:
Crossing Grand Canyon on a tightrope
Flying Wallendas circus family is famous for their unbelievable
death-defying feats. During daring act several relatives have died
including Karl Wallenda who fell to his death in Puerto Rico in 1978.

But they cannot be stopped. They continue to indulge in such amazing
acts as the word DEATH may not be in their vocabulary! This time it was
Nik, the seventh generation high-wire artist who defied death while
crossing the massive Grand Canyon.
With no safety harness and a 1,500ft drop to certain death beneath
him, tightrope walker Nik Wallenda took 22 minutes to make the
death-defying crossing in front of 500 spectators. He was forced to
pause twice as he was blasted by 35mph gusts of wind. Carrying a pole
for balance, the daredevil was twice forced to pause and crouch as he
was blasted by 35mph gusts on the two-inch-wide cable.
Nik, who was wearing a microphone, was heard to say: "Thank you,
Lord. Thank you for calming that cable, God."
He took 22 minutes to finish the death-defying 1,300ft walk and
jogged the final few steps as about 500 spectators, including wife
Erendira, cheered him on. Nik, 34, said: "It was way more windy and it
took every bit of me to stay focused the entire time."
After the trip across the Little Colorado River Gorge near the Grand
Canyon in Arizona, Nik has set his sights on tackling a 4,000ft wire
between New York City's Empire State and Chrysler buildings.
Nik has earned seven world records and last year became the first to
cross the brink of Niagara Falls on a tightrope.
Bride does a bungee jump on her wedding day

Bungee jump bride Sarah
Wilkinson |
A bride shocked wedding guests by bungee jumping from a bridge during
her wedding reception in Scotland recently.
Daredevil Sarah Wilkinson stunned family and friends when she
celebrated tying the knot by plunging 130 feet off a bridge - twice.
She plunged from the Garry Bridge, near Killiecrankie, Perthshire,
Scotland, in a rockabilly 1950s-style wedding dress. And she amazed
husband Kev, 25, when she got out of the water and jumped in again -
this time backwards. Sarah, from Bridge of Cally, said: "I like doing
different things and there's nothing better than bungee jumping on your
wedding weekend."
She got the idea after talking to staff at Nae Limits' Log Cabin in
Kirkmichael - the wedding venue.
Sarah added: "It was my first jump and I absolutely loved it." |
