in 1883, a Mexican astronomer, José Bonilla, saw 450 unidentified objects crossing before the sun.
His editor dismissed the phenomenon and suggested it was caused by insects and bugs on the telescope.
In 2011, a group of researchers reanalyzed the data, and discovered the horrifying truth, that The Human Race was going to extinct!
Turns out, the objects were actually fragments of a billion-tone comet passing within a few hundred to few thousand kilometers of Earth, with the energy to wipe out the human race completely, same as the one which caused the extinction of Dinosaurs.

Observation
More than 400 Misty Objects in front of the Sun
August 12, 1883
Mexican Astronomer: José Bonilla
Saw 450 dark, unidentified objects crossing before the Sun
Each one surrounded by a glowing mist.
But no one else on Earth saw such a thing.

So What Was It?
Shocking!!!
Fragments of a billion-ton comet
size from 50 to 800 meters across and that the
parent comet must originally have tipped the
scales at a billion tons or more
Passing within a few hundred kilometers of Earth
between 600 km and 8000 km of Earth. That’s
just a hair’s breadth.
Each at least as big as the Tunguska object
So if they had collided with Earth we would
have had 3275 Tunguska events in two days,
probably an extinction event.
How close Earth may have come to catastrophe
Bonilla observed these objects for about three
and a half hours over two days. This implies an
average of 131 objects per hour and a total of
3275 objects in the time between
observations.
In 2011, National
Autonomous University of
Mexico reanalyzed the
observation

Tunguska Event
What happened?
• It is the largest impact event on Earth in recorded
history.
• Occurred near the Podkamennaya Tunguska River in
what is now Krasnoyarsk Krai, Russia, at about 07:14
KRAT (00:14 UT) on June 30, 1908.
• The size of the object is estimated on the order of 60
m to 190 m.
• The energy of the blast was most likely between 10
and 15 megatons of TNT and about 1,000 times
greater than that of the atomic bomb dropped on
Hiroshima, Japan

Tunguska Event
What happened?
• The Tunguska explosion knocked down some 80
million trees over an area of 2,150 square kilometers.
• The shock wave from the blast knocked people off
their feet and broke windows hundreds of kilometers
away.
• It produced fluctuations in atmospheric pressure
strong enough to be detected in Britain.
• Over the next few days, night skies in Asia and Europe
were aglow; it has been theorized that this was due to
light passing through high-altitude ice particles that
had formed at extremely low temperatures

What Can We Do?
What about future impacts?
! Monitor
Find and Monitor near Earth objects
The first thing to do is to find and monitor near Earth objects above a
certain size. NASA is already doing a pretty good job with that, but the work
is not over as they are still finding more and more every year. Calculating
their orbits far in the future is the next step, and if any seem to be coming a
bit too close to Earth, we need to monitor them extra-closely and refine
orbits until we are sure one way or the other.
Test stuff
The second part is having the capabilities of rapidly deflecting an inbound
object. Ideally we would have all this stuff tested and ready to go within a
relatively short time frame, rather than having to actually do the R&D and
build the stuff after we've discovered a dangerous orbit. You don't want
your test-run to have millions, if not billions, of lives hanging in the
balance...
