Did the Cosmos Deliver a Googly? ‘Meteorite’ Lands on Cricket Pitch

While enjoying a cricket county match, two spectators were apparently treated to one of the rarest of cosmic events: a meteorite falling from the sky, landing right in front of them. The “dark” rock, measuring 5 inches wide, broke in two on impact. Amazingly, a piece hit one of the witnesses.

“One piece bounced up and hit me in the chest and the other ended up against the boundary board,” said Jan Marszel. “It came across at quite a speed – if it had hit me full on it could have been very interesting.”

It’s not clear from the Telegraph‘s minimally skeptical article when this happened (I’m assuming it was during the recent Middlesex vs. Sussex game in Uxbridge, northwest London, using the tidbits of information from the text) and the only expert opinion cited is that of Dr. Matthew Genge, a meteorite expert at Imperial College, who hasn’t handled the evidence yet.

“If this turns out to be a meteorite it’s very exciting and would be the first fall in the UK since 1992,” Genge points out.

(That last statement isn’t very accurate. I’m certain that there have been many meteorites falling onto the UK since 1992. If proven true, this would be the first witnessed fall in the UK since 1992.)

UPDATE (July 27, 10:22 am PT): With thanks to Philip Stobbart, who also commented on the Uxbridge object, some clarification of Genge’s quote has been provided, I stand corrected:

Ian O’Neill does a good job of debunking this, with one minor error. A ‘fall’ to a meteor expert is one of two categories of meteorites, falls and finds, referring to when they were seen – falling, or found later – not to meteorites actually physically falling. The papers made the same error, although they accepted the idea of this being the first fallen meteorite since 1992…

Original post continues:

Thank goodness the eyewitness account didn’t include a description about smoke bellowing from an incendiary-like pebble (i.e. the recent Israel spoof/weapon), but there are some huge question marks hanging over the validity of the Uxbridge object.

The first red flag is that one of the witnesses said: “…out of a blue sky, we saw this small dark object hurtling towards us.” I might be wrong, but spotting a 5-inch wide object flying through the air, at speed, ain’t easy. I would have thought the only time they were alerted of the ‘meteorite’ would have been when it hit the ground. Or when it hit Marszel in the thorax.

Secondly, was the ‘meteorite’ really 5 inches wide? After a quick search, I found a photograph of the offending object:

5 inches? Are you sure? I know us guys are known for overcompensating, but this is ridiculous. Granted, it’s probably just shoddy reporting, but that piece of rock is barely an inch wide.

Also, when a meteoroid blasts through the Earth’s atmosphere, a huge amount of heat is generated around it, creating a ‘fusion crust.’ This crust should be very obvious surrounding recently fallen meteorites. Looking at this picture, no fusion crust is visible. It could be that we are looking at the interior of the broken ‘meteorite,’ and the black fusion crust is on the other side, but there’s no indication in the photo that this is a bona fide space rock.

If I were to place a bet, I’d say that this is not a meteorite. However, it will be interesting to see what the experts think once they are able to study the sample.

Space Agency Confirms Indonesia ‘Meteorite’

So, according to The Jakarta Post, last week’s ‘meteorite’ (these skeptical ‘quotes’ are getting ridiculous) that smashed down in East Jakarta, through the roof of a house, was in fact a meteorite. But this time, a scientist from the National Aeronautics and Space Agency (Lapan) has confirmed the original report to be true.

“The heat exposure showed that the object came with high speed and heat,” said Thomas Djamaluddin, an astronomy researcher.

According to another publication, the meteorite “was as big as a coconut.”

However, no meteorite remnants have been recovered from the scene. While it’s possible that the meteorite vaporized on impact, I strongly doubt there would be much of a house left after such an energetic blast.

Djamaluddin does point out that perhaps the meteorite had a “fragile structure,” a potential reason why there’s no fragments left. But that begs the question: If the meteorite was that fragile, could it really slam through the roof, destroy the second floor, explode, excavate a crater in the first floor and cause damage to two neighboring properties?

I’m not totally discounting the idea that this might have been a meteorite impact, but the evidence remains as sketchy as last week. So I’m sticking with my original thought that this “blast” was more likely terrestrial and not extraterrestrial in origin. But on the outside chance this was a meteorite, the neighborhood had a very lucky escape in that the space rock was big enough to cause significant property damage, yet small enough to stay contained.

Indonesia ‘Meteorite’ Wiped Out a House… Or Not.

A week after Israel played host to the amazing burning ‘meteorite’, another report is coming in about a ‘meteorite’ strike in East Jakarta, Indonesia. (Note the use of the famous ‘skeptical quotes’.)

On Thursday, a falling object crashed through the roof of a house causing moderate damage. There was also light damage to two adjoining properties. Fortunately, there are no reported injuries.

According to a report in the Jakarta Globe, there was a “blast” that resulted from the impact and there was a deep crater in the floor of the house. After creating the impact crater in the floor, the ‘falling object’ bounced.

I suspect the object impacted at high velocity, hit the floor, bounced back and hit the ceiling, then fell back down,” said a researcher from the Indonesian National Aeronautics and Space Agency (Lapan). “It’s extremely difficult to recover the fragments, what with the rubble and broken glass, and it being so dark in here.”

The article also states that there was evidence for a residual heat footprint and melted items around the crater. Apparently, these facts all point to evidence that a meteorite, or some man-made space junk, was involved.

Although the details are sketchy, there are a few points that concern me about this meteorite report:

First, if this ‘meteorite’ was large enough to create a “deep” crater (there’s no information about the crater’s approximate size), that would suggest it was a hyper-velocity impact. Not only is this kind of impact very rare, I doubt there would be anything left of the building.

Unless “moderate damage” means “there is no house left,” I strongly doubt the crater was caused by a meteorite.

Secondly, according to the Lapan scientist, the space rock “bounced.” While this is possible — take the Virginia meteorite that crashed through the roof of a doctors office, bouncing off the floor of an examination room, for example — if its impact was energetic enough to excavate a sizable crater (and produce a “blast”), then I doubt much of the meteorite would be left to “bounce.” It would have disintegrated, got lodged deep in the bottom of the crater, or not produced a crater at all.

Thirdly, the article states: “the residual heat footprint and melted items pointed to a meteorite.” As I’ve said before, meteorites are usually cold when they make landfall (assuming they are small enough to be slowed by our atmosphere), so this residual heat did not come from the meteorite. If the meteorite was large enough to slam into the house at hyper-velocity speeds, or hit a gas canister, then perhaps there might be some “residual heat.” But in this case, I strongly doubt there would be any house left.

Fourthly, according to Evan Irawan Akbar, from the Bosscha Observatory in Lembang, this event has occurred shortly after the Lyrid meteor shower which ended on Monday. So he rules out any connection. Which is fortunate, as this meteor shower is caused by the Earth passing through a harmless dust tail created by the periodic Comet C/1861 G1 Thatcher.

But then he drops this clanger: “It could, however, be part of the Eta Aquariid meteor shower, which peaks on May 7 and 8.”

The Eta Aquariid meteor shower is caused by dust trail from Halley’s Comet… last time I checked, dust grains from comets have never been linked with house-killing chunks of rock. Comets are made from ice and dust, stuff that easily burns up when hitting our atmosphere. These are meteor showers, not meteorite showers.

The extent of the damaged caused is also a little strange. From the article: “It blasted a hole in the second floor of the house, sending furniture falling to the first floor, and tore big holes in the walls.” Doesn’t that sound like an explosion?

Apparently the police have ruled out speculation that this was a gas canister explosion and although there is “no conclusive proof the damage was caused by a meteorite, it was the most likely explanation.”

Alas, meteorite impacts aren’t likely explanations, terrestrial explanations are the most “likely.” The fact that an Indonesian counter-terrorism squad has been dispatched to the area to look for traces of explosives suggest the authorities aren’t placing all their bets on this being a meteorite impact either.

Israel ‘Meteorite’ Isn’t a Meteorite [UPDATE]








[Original post below]




However, looking at the video above, that’s no meteorite.




Thanks Avi Joseph for pointing me to this video!

Now THAT is what I call a fireball!

Three frames from the South African CCTV footage.
Three frames from the South African CCTV footage.

Having seen some footage of the South African fireball last weekend, I thought it was quite impressive. However, a new video looking along a Johannesburg motorway has appeared online, and it’s superb.

I can’t find much information about this event, but it happened on November 21st and no fragments have been found so far.

Just in case you were in any doubt as to how much energy is released when a chunk of rock hits our atmosphere, this should give you a good impression:

I could almost feel the heat and hear the *KABLAAAM*.

Deflecting Doomsday Asteroids… and Plundering Them

A metorite impact would be very bad, but using asteroid deflection techniques could provide mankind with a lucrative opportunity (©Discovery Channel)

I’ve always found asteroids to be fascinating. They are often surprisingly big, they contain a wealth of information about the history of the Solar System… and, let’s be honest, they’re frightening.

There are thousands of asteroids out there, often collecting in clearly defined belts or gravitationally stable regions known as Lagrangian points. However, many are not so well behaved; they seem to have their own agenda, flying around the Solar System in their own orbits, sometimes buzzing the Earth.

Fortunately, the vast majority of these rocks are harmless; if they hit our atmosphere they might create a dazzling light show, burning up, possibly even exploding as a fireball. Sometimes though, a big asteroid might be observed and astronomers become a little concerned. The next known threat that might hit us is the famous asteroid named Apophis that is expected to make an uncomfortably close encounter with Earth on April 13th, 2036. The odds of Apophis hitting us in 2036 (not 2029 as quoted in the above video) are 45,000:1, which may sound fairly unlikely, but if you start comparing those odds with dying in a plane crash, or being hit by a car, you’ll see that actually, a one in 45,000 chance are the kind of odds you’d happily quote when placing a bet in a Vegas casino. I have a chance!

Yes, and there’s also a chance of a 350 metre-wide asteroid hitting us in 2036, so perhaps we should start planning for the worst?

Fortunately, we have some lead time on Apophis, and we’ll learn more about the chunk of rock when it flies past the Earth in 2029. And that’s what it’s all about: lead time. If mankind spots a potentially deadly asteroid approaching us, we’ll need as much time as possible to nudge it off course.

In a video I just stumbled across on, Joseph A. Nuth III from NASA Goddard Spaceflight Center shares his views on what we could do to prevent a potential asteroid catastrophe. By developing asteroid deflection techniques, we’ll also be presented with an opportunity. As pointed out by Nuth, if we have the ability to deflect an asteroid, perhaps we can steer it into lunar orbit, so we can carry out mining operations…

Fire at Auckland Warehouse Caused by Meteorite Impact? (Update)

Update (16:00 PST Dec. 14th): Eyewitness accounts are becoming more detailed, if you were in the Auckland area at 10pm (December 13th) and you saw something, please let me know (by leaving a comment below). Please give as detailed an account as possible, including your location and the direction at which you saw the meteorite. Hopefully we’ll piece this event together…

Auckland warehouse fire. Meteorite or foul play? (Paul Tonkin)

A fire erupted in an Auckland warehouse shortly after several eyewitness reported seeing a meteorite over the North Island of New Zealand. One witness (named “Mike”) even went as far to say that he watched the fiery object hit the Ponsonby area of the city, followed by an exploding noise.

The time of the several eyewitness reports (not amateur astronomer reports I want to point out) and the start of the blaze appears to correlate (although the local media is a little sketchy about the details at the moment). Apparently the fire caused serious roof damage to the warehouse and there was one minor casualty (a man who happened to be in the building at the time). However, none of the surrounding buildings were touched.

The meteorite was observed at around 10pm last night, and the fire was eventually extinguished at 11:30pm.
