Many Vancouver Island residents took notice as a bright streaking light flared across the skies Sunday.

Described by some as a "fireball" followed by a loud explosion just after 5 p.m., reports of the celestial event lit up social media from around the island — including Saanich, Duncan, Port Alberni and Campbell River.

Some who reported hearing the loud bang said they thought it might have been an earthquake, but B.C. seismologist John Cassidy suggested it may have been a meteor.

We received 9 reports about a fireball seen over CA and ID on Friday, December 10th 2021 around 13:48 UT.

For this event, we received one video and one photo.

According to the description made by the Smart project on their website, a "spectacular fireball" shot across the Andalucian sky on the night of December 7, at 10:31pm. "Its brightness was similar to that of the full moon", says the site.

Jose Maria Madiedo is the researcher responsible for carrying out this analysis for the SMART project. He is an astrophysicist from Granada's Instituto de Astrofisica de Andalucia IAA-CSIC.

Madiedo pointed out that the rock that caused this phenomenon, entered the Earth's atmosphere at a speed of about 86,000km/h, and came from an asteroid. These types of rocks that intersect the Earth's orbit are called "meteoroids".

Most mornings, retired scientist Derek Poulton gets up and checks a special camera.

One of just three in Victoria, his camera at Mooroopna switches on from dusk until dawn every night with the aim of capturing footage of meteors.

And when Mr Poulton checked the camera on the morning of November 29, he spotted something.

"Lo and behold, we had a fireball!"

"Initially I could just see this flash," Mr Poulton said.

"You can process the data as a short video and when I did, you could see this huge bolide [an exceptionally bright meteor] that's moving through the atmosphere. It was very exciting to see that sort of vision."

After 7:00 pm on the 10th, a "fireball" that shines brightly among shooting stars was observed in a wide range of the country.

NHK cameras in Aichi and Chiba prefectures shot bright and shining fireballs flowing down for a few seconds like a tail.

It is said that the National Astronomical Observatory of Japan has also received information that fireballs have been witnessed in a wide area such as Saitama and Fukuoka prefectures.

According to the curator of the Hiratsuka City Museum in Kanagawa Prefecture, Daichi Fujii said, "Because the fireballs are being observed and the meteor shower is active, we may be able to find them during the year-end and New Year holidays." ..

A groundbreaking study led by researchers at Florida Atlantic University and an international team of scientists conclusively confirms the time year of the catastrophic Chicxulub asteroid, responsible for the extinction of dinosaurs and 75 percent of life on Earth 66 million years ago. Springtime, the season of new beginnings, ended the 165-million-year reign of dinosaurs and changed the course of evolution on Earth. Results of the study, published in the journal Scientific Reports , greatly enhances the ability to trace the first stages of damage to life on Earth. FAU's Robert DePalma, senior author and an adjunct professor in the Department of Geosciences, Charles E. Schmidt College of Science, and a doctoral student at the University of Manchester; and Anton Oleinik, Ph.D., second author and an associate professor, FAU's Department of Geosciences, contribute to a major scientific advancement in the ability to understand the massive impact that brought an end to the dinosaurs.

"Time of year plays an important role in many biological functions such as reproduction, feeding strategies, host-parasite interactions, seasonal dormancy, and breeding patterns," said DePalma. "Hence, it is no surprise that the time of year for a global-scale hazard can play a big role in how harshly it impacts life. The seasonal timing of the Chicxulub impact has therefore been a critical question for the story of the end-Cretaceous extinction. Until now, the answer to that question has remained unclear."

For decades, it has been known that the cataclysmic Chicxulub asteroid impact hit the Yucatan peninsula 66 million years ago. The impact triggered the third-greatest extinction in Earth's history, dramatically changing global biomes in ways that directly relate to current global ecological crisis. Yet, the finer details of what happened after impact and how those events led to the third-worst mass-extinction in Earth's history remain very hazy.

The new study was a long-term effort that started in 2014 and applied a combination of traditional and cutting-edge techniques to piece together a trail of clues enabling identification of the season for the Chicxulub impact event. DePalma examined the Tanis research locality in southwestern North Dakota, one of the most highly detailed Cretaceous-Paleogene (KPg) boundary sites in the world, to understand the inner workings of the extinction event. The research provides important new data while building new academic bridges.
