A team of scientists claims to have found the first-ever definitive evidence of a comet striking Earth.
After conducting a series of analyses, the researchers determined that a mysterious black pebble discovered years ago in the Egyptian desert is a piece of a comet nucleus the first ever discovered.
"Its a typical scientific euphoria when you eliminate all other options and come to the realization of what it must be," study lead author Jan Kramers, of the University of Johannesburg in South Africa, said in a statement. [Best Close Encounters of the Comet Kind]
The pebble, which the team has named "Hypatia" in honor of the ancient female mathematician, astronomer and philosopher Hypatia of Alexandria, is also studded with diamonds, which makes sense considering its cometary origin, researchers said.

Like this is a good thing?
Is it a bad thing?
I just found it interesting.
Poor Comet, I hope Rudolph is OK.
When’d’it strike? 2011?
How about this one?
i thought that was a coprolite
Look at a map of North America. Look at the Gulf of Mexico. That sure looks like a giant ancient meteor carter that the ocean filled up. At least it does to me. Because the Gulf of Mexico is round like a meteor crater. One big enough to pop off all life on Earth millions of years ago. Except for the ants, of course.
I am also amused by the enthusiastic tone of the article.
The last documented comet event occurred in 1908 in Russia near Tunguska in a deserted region of Siberia. Fortunately for us carbon life forms, it was small and it exploded about 10 miles above the earth instead of impacting it.
Seems it knocked down everything standing for a 15 mile radius and created a earth quake of 5 on the richter scale.
Well... yeah... the one in the photo is. BUT.... the original one was from a comet.
Not only that, but that has happened at least six times.
I think a meteorite differs from a comet due to composition.

not that i care if those people worship fossilized flying reindeer crap but Comet should be capitalized
Meteors are rock and/or metal while comets are mostly ice. A meteor that hits the ground is a meteorite. Most meteorites are metallic (mainly nickel and iron) because rocky meteors usually explode in the atmosphere (their composition causes them to break up from the heat).
Nobody is sure whether Tunguska was a comet or a meteor. The explosion is consistent with a large rock entering the atmosphere at a high speed.
Thank you for clarification.
They found my lucky black rock!
Some small mammals also survived the CretaceousPaleogene extinction event some 66 million years ago...luckily for us!

!! The proverbial needle in the haystack. What are the odds.
What about that big hole in Arizona?
Where did they get the comet core sample with which to compare it? It's an educated guess at best. Maybe right, maybe wrong.
My bad. Considering I have one of these in the kitchen cabinet, you would think I would not have made that kind of goof.

No to the Gulf of Mexico. The 65myo boloid that killed the dinosaurs was partly in Yucatan and somewhat more in the Gulf of Mexico, but with a diameter of 120 miles was not big enough to shape the whole Gulf. The 200mya plus one that killed most species has not yet been definitively located. On the other hand, anyone know about Hudson’s Bay??
Yeah, it definitely looks like one, but it wouldn’t be from the K-T impact. When the Alvarezes were trying to find the impact site, someone wrote in to one of the sci mags suggesting Iceland — that the impact punched a hole through the crust and produced the volcanic phenom we now know and love there. :’)
