Spectacular Meteor Fireball Lights Up Alberta Skies
On November 13, 2024, residents of Airdrie and nearby areas witnessed a spectacular greenish-blue fireball streaking across the sky, captivating early risers and stargazers. This meteor sighting, reported around 6:34 a.m., sparked excitement on social media as locals shared videos and images. NASA explains that such fireballs occur when meteoroids enter the atmosphere, creating stunning light displays. With upcoming meteor showers like the Orionids and Southern Taurids, stargazers have more opportunities to experience these celestial wonders.

Potential Meteorite Impact Site Discovered in Quebec
A potential meteorite impact site has been discovered in Quebec’s Cote-Nord region, identified by outdoor enthusiast Joel Lapointe. The 15-kilometer-wide circular formation around Marsal Lake is under investigation by geophysicist Pierre Rochette and his team. If confirmed, this could be the first new impact crater found since 2013, adding to Canada’s 31 known impact sites. Researchers are analyzing samples and searching for shatter cones to verify the impact hypothesis, with further studies planned for 2025.
Residents urged to search for meteorite fragments in Staffordshire
Residents of Staffordshire are on the lookout for meteorite fragments after a bright fireball was spotted over the Midlands. The UK Fireball Alliance suspects a meteorite may have landed near Blythe Bridge and Uttoxeter. Scientists warn against touching any rocks found and describe the meteorite as around 500g, black or brown, and 5-10cm wide. Despite searches, the meteorite remains elusive. The community is encouraged to report any findings to UKFAll or the Natural History Museum.

Antarctica’s Melting Ice Threatens Valuable Meteorite Discoveries
Antarctica, known for its abundance of meteorites, is facing a concerning trend as climate change causes the ice to melt, making these valuable space rocks increasingly difficult to find. A recent study highlights the impact of warming temperatures on the Antarctic ice sheet, leading to the disappearance of over 5,000 meteorites each year. This loss not only hinders scientific research but also underscores the far-reaching impact of climate change on even the most remote regions of the planet.
Antarctic Meteorites Threatened by Climate Warming, Study Finds
A new study published in Nature Climate Change reveals that climate warming is causing many extraterrestrial rocks to be lost from the surface of Antarctica by melting into the ice sheet. The research predicts that approximately 24% of meteorites will be lost by 2050, potentially rising to approximately 76% by 2100 under a high-emissions scenario. The findings raise concerns about the future of Antarctic meteorites and the potential loss of valuable extraterrestrial rocks due to climate warming.
Groundbreaking Discovery in Winchcombe Meteorite
Scientists have made a groundbreaking discovery in the Winchcombe meteorite, identifying key nitrogen compounds, including amino acids and hydrocarbons, without chemical treatments, using a novel detector design. This finding is significant for research into life’s origins on Earth and has been facilitated by a high-resolution electron microscope at the SuperSTEM laboratory. The research team, in collaboration with British colleagues, has demonstrated, with a high degree of precision, the existence of important nitrogen compounds in the meteorite, including amino acids and heterocyclic hydrocarbons, without applying any chemical treatment, using a new type of detector design. The results of this study have been published in the journal Nature Communications.
