On Tuesday, March 18 at 10:24 pm EDT a super-bright fireball lit up southwestern Ontario skies.

Here is a photo captured by Univ. Western Ontario all-sky camera of the meteor event. Researchers now estimate it was a meteor the size of a basketball that entered Earth`s atmosphere. The cosmic intruder spend about 5 seconds traveling through North American skies before the air pressure pulverized it. Meteor experts say this is the first time in a half decade that such a bright event happened in Ontario.

The space rock most likely fragmented with pieces probably making it to the ground. Now the hunt is on for meteorites just 5 km NW of St. Thomas, Ontario. According to researchers the odds of finding a fragment of the meteor are small since it’s like looking for a needle in a haystack but the general public has the best shot.

Stay tuned for more details as they are made available.

Glimpse Giant Asteroid Glide Through Taurus

Written by The Night Sky Guy on February 6, 2014 – 4:22 pm -

A giant asteroid, first seen 110 years ago, is making a rare appearance for backyard astronomers this month.

Usually so far away from Earth that only very large telescopes can spot it, 532 Herculina will be coming closer to Earth than usual, thereby allowing small backyard scopes to observe it as it sails through the horns of Taurus, the bull constellation in the evening skies.  Making the hunt even easier, the 230 km wide space rock will be gliding past a naked-eye star this week and then a famous supernova remnant- the Crab nebula.

Despite its high asteroid number – referring to the order of its discovery – Herculina probably ranks in the top 10 in terms of mass. The giant rock has also been at a center of a mystery surrounding the possibility of it having an orbiting satellite asteroid. Despite multiple observations by amateur astronomers watching Herculina during occultations of stars back in the late 1970’s and 80’s, Hubble Space Telescope failed to find any evidence of a moon when it looked in 1993.

Miss this encounter with Herculina and you will have to wait until 2019.

Eastern Canada Meteor Event Confirmed

Written by The Night Sky Guy on November 28, 2013 – 7:10 pm -

If skies would have been clear Tuesday night then skywatchers might have witnessed a bright fireball like this one.

If skies would have been clear Tuesday night then skywatchers might have witnessed a bright fireball like this one.

Yes that loud sonic boom and flash of light in the sky on Tuesday night at 7:47 pm EST was indeed a meteor racing across the southern Ontario, eastern Quebec region.

Prof.Peter Brown, a leading expert on meteor physics at the University of Western Ontario reports that infrasonic microphones, part of the USArray network of seismological detectors across the continent detected the series of shockwaves produced by the break up of the meteor as it traveled at supersonic speeds across the region.

“From a very casual examination of the records from five of these stations, it appears the fireball went roughly north-south passing almost right over the Island of Montreal,” said Brown in an email statement.

According to the data, the meteor had energy- on the order of less than a ton of TNT at most, indicating that the space rock might have weighed in the tens of kilograms category, explained Brown.

In comparison, the Russian meteor event in February measured some 20 meters across and had enerrgy equivalent of more than 500 kilotons of TNT.

Possible Meteor Rattles Ontario-Quebec Skies

Written by The Night Sky Guy on November 27, 2013 – 12:16 am -

fireball-bolide-fragments
Folks from Ottawa, Ontario through Laval, Quebec are reporting a blue flash of light followed by a sonic boom that occurred around 7:50 pm ET, November 26th.

This may be signs of a meteor event and could indicate the stone – which could be anywhere in size from a sofa to compact car- may have fragmented with some bits making it to the ground.  Scientists will comb through all the observation reports along with any photo and video evidence so that they can triangulate the trajectory of the possible meteor fall.

Thankfully this appears to be a minor event since there are no reports of any damage -not like what we saw earlier this year occur in Siberia where a 20 meter wide, 60 ton space rock exploded in the atmosphere and injured 1500.

King Tut Connection to Ancient Comet Crash

This is an artist's rendition of the comet exploding in Earth's atmosphere above Egypt.

In the Sahara, a team of scientists claim to have found the first evidence of a comet directly impacting Earth.

About 28 million years ago a comet exploded over Egypt, creating a 3600°F (2000°C) blast wave that spread out over the desert below. The fiery shockwave melted the sand, forming copious amounts of yellow silica glass scattered over 2,300 square miles (6,000 square kilometers) of the Sahara.

Polished into the shape of a scarab beetle, a large piece of this glass found its way into a brooch owned by the famed Egyptian boy king Tutankhamen.

Perseid Meteor Shower Starts Peak Activity

Written by The Night Sky Guy on August 11, 2013 – 2:04 pm -

Warm summer nights and awe-inspiring shooting stars are an unbeatable combination!

That’s why skywatchers look forward to the annual Perseid meteor shower. Visible with the naked eye from the city to cottage country, dozens of “shooting stars” will light up the late-night skies. With the waxing crescent moon setting below the horizon in the early evening, the peak dates of August 11th through the 13th, this cosmic light show will surely put on an impressive display. Skywatchers get to see a flurry of shooting stars start 10 pm with rates increasing until pre-dawn hours. Anywhere from 20 to 80 shooting stars per hour depending on local sky conditions and amount of light pollution.

Here also is my Night Sky episode that talks all about the shower…

Russian Meteor Blast Was Surprisingly Big

Earlier this year in February the world had a wake-up call when a giant 17 ton rock from space entered the atmosphere in Siberia and created a giant air-blast that literally was felt around the world.

A new study was released this week that analyzed this meteor impact and the results show that when the hypersonic meteor imploded in the upper atmosphere, it created a shockwave that propagated across the globe – not once but twice.

Find out how this big blast ranks in terms of meteor encounters in recent history and how often such cosmic events may occur, in my story for National Geographic News.

Brightest Moon Blast Ever Recorded

A boulder-sized meteor slammed into the moon in March, igniting an explosion so bright that anyone looking up at the right moment might have spotted it, NASA announced Friday.

NASA’s Meteoroid Environment Office is reporting the discovery of the brightest impact seen on the moon in the eight year history of the monitoring program.

Some 300 lunar impact events have been logged over the years but this latest impact, from March 17, is considered many orders of magnitude brighter than anything else observed.

Check out more details on this lunar explosion and what NASA will be doing at my National Geographic News story.
