Meteor fireball spotted in evening skies over Cork, Ireland

The fireball was seen from many different areas of Cork last night

An unusual sight was spotted in Cork skies last night when a meteorite was filmed blazing through the sky before it had even gone dark.

Footage shared on Twitter last night shows the fireball blasting across the Cork skyline while it was still bright.

The video was taken in Ballinhassig at around 9:26pm with experts saying it would be unusual for it to be a meteorite so early in the night.

Daylight meteor fireball filmed over San Francisco, California

A METEOR which flew through the Californian skies in broad daylight left some locals wondering if the incoming space rock hit the Santa Cruz mountains.

Earlier today, a meteor flew through the skies of California. Tens of people in California saw the meteor, most of those around the San Francisco area. Witnesses flocked to the International Meteor Organisation (IMO) to report their sighting.

Some were concerned that it was going to make land surface - which it did not.

A person named Cole told the IMO: "It was extremely close looking compared to any other meteor-like object I've observed and was headed towards the direction of Briones Reservoir.

"Could've touched down not too far from my location but am unsure. Very visible fragmentation."

Overview of the Younger Dryas impact hypothesis debate

Orange dots represent 28 sites with peaks in both platinum and other impact proxies such as high-temperature iron-rich microspherules. Red dots represent 24 sites with impact proxies but lacking platinum measurements. The yellow dot indicates the Pilauco site, Chile, described in detail in Pino et al. (2019). A new site in South Africa, Wonderkrater, has been identified since this map was first published (Thackeray et al., 2019).
Indefatigable genius and digital friend of the Tusk, Dr. Martin Sweatman, authored a surprise blockbuster this week. Below is a peer-reviewed and fully accepted pre-online synthesis overview of the Younger Dryas Impact controversy since the very first paper in 2007. 'The Younger Dryas impact hypothesis: review of the impact evidence' concludes — in perhaps the world's most appropriate and respected scientific journal — that based on the published evidence, our modern world is indeed birthed of a horrendous global catastrophe ~12,881 years ago. It is a lengthy, detailed, fair and lucid tour-de-force in support of The Event based on Martin's reading of the entire debate.

Martin is an example to the Tusk of how many, many people there are on earth. You have to have 8+ billion humans in order to have enough brain matter and determination on the end of the bell curve to find a just one single, well-qualified, unbiased, poly-curious scientist, so determined to find the truth that they will to read every last word — and then write every last word — well.

Geologists identify rare meteorite impact site in Dakota County

Small grains of shocked quartz buried deep under ground in Inver Grove Heights, Minn., are evidence of an ancient meteorite impact in the area
An area around Inver Grove Heights, Minn., is the site of an ancient meteorite crash, according to recent analysis by the Minnesota Geological Survey.

The discovery came as scientists were updating geologic maps of Dakota County. They identified anomalies in the rock record — certain layers appeared out of order or irregularly sized. This led to further examination and the identification of small grains of shocked quartz, which is known to be produced only by the extreme shock and compression of a meteorite impact or nuclear explosion.

"It's really exciting and new," geologist Julia Steenberg told MPR News host Cathy Wurzer. Steenberg and her colleagues are hoping to do more research to better understand the age of the impact and the size of the meteorite involved.

Globally, known meteorite impact sites are exceptionally rare. This is the first identified in Minnesota and one of fewer than 200 in the world.

Loud mysterious boom has residents of south-west Sydney, Australia scratching their heads

Mystery boom - stock
Experts are baffled by reports of an explosion heard across south-west Sydney with no identified sources nor any indication as to where it came from.

Authorities received multiple reports from residents saying they heard an "explosion" on Saturday night, but found no evidence of an explosion.

Fire and Rescue NSW and NSW police responded to the calls, but said they found nothing, not even a fire, to indicate an explosion had taken place.

Mystery surrounds the incident, with reports the sound was heard across Marrickville, Roselands, Bardwell Park, Campsie and Belmore.

Residents reported windows shaking, and that the sound was something like an explosion or a backfiring car, but with no visual indicators.

The American Meteor Society (AMS) received 39 reports (event 2671-2021) about a meteor fireball seen over MN, ND, SD and WI on Sunday, May 9th 2021 around 08:03 UT.

For this event, it received 6 videos and one photo.

Meteor seen across Puerto Rico at approximately 8:02 PM Friday 7th May 2021
A bright meteor was spotted across the night skies of the Greater Antilles on Friday night. Those who spotted it say the brilliant meteor appeared as a "huge green ball with a long tail."

The meteor was visible from Puerto Rico, the Dominican Republic and Cuba at approximately 8:02 PM Friday 7th May 2021.

According to the Caribbean Astronomy Society (SAC), "It was a space rock of metallic content friction with our atmosphere."

New Comet C/2021 E3 (ZTF)

CBET xxxx & MPEC 2021-J71 , issued on 2021, May 06, announce the discovery of an apparently asteroidal object (magnitude ~19.5) on CCD images taken on March 09.5 UT with the 1.2-m Schmidt telescope at Palomar in the course of the "Zwicky Transient Facility" (ZTF) search program. This object has been found to show cometary appearance by CCD astrometrists elsewhere. The new comet has been designated C/2021 E3 (ZTF).

Stacking of 14 unfiltered exposures, 120 seconds each, obtained remotely on 2021, March 19.2 from Z08 (Telescope Live, Oria) through a 0.7 m f/8 Ritchey Chretien + CCD, shows that this object is a comet with a compact coma about 7" in diameter (Observers E. Guido, M. Rocchetto, E. Bryssinck, M. Fulle, G. Milani, C. Nassef, G. Savini, A. Valvasori).

A huge, glowing fireball lights up the sky over Japan

A glowing object crossing the sky was captured on Monday night over the Fukuoka and Nagasaki prefectures in Japan. The phenomenon was captured on video by cameras in the area and seen by several witnesses who described it as a ball of light, pick up the chain NHK.

Satoshi Imamura, an expert in space issues, dispelled doubts about the nature of the object and explained that it was a bright shooting star known as a fireball or bolide. The intense luminosity occurs when dust and asteroid fragments in outer space enter the atmosphere and burn.

Meteor fireball spotted on deputy's dashcam in Collier County, Florida

fireball
A Collier County deputy captured a unique phenomenon on her dashcam while out on patrol this week.

Cpl. Nicole Medenwald saw a meteor, and rather than savor the memory, she got to review the proof!

The Collier County Sheriff's Office said she had just come from conducting a traffic stop. She repositioned her patrol car to face North 15th Street to watch for cars.

"I saw a green light and then it lit up the sky," Cpl. Medenwald said. "It reminded me of lightning at night the way the sky lit up."

Cpl. Medenwald said she's seen meteors before but has never seen one break the atmosphere and light up the sky.
