Top Stories Tamfitronics The so-called Chicxulub impactor was a carbonaceous-type asteroid that had formed beyond the orbit of Jupiter, according to a new paper published in the journal Science.Ankylosaurus magniventrisa large armored dinosaur species, witnesses the impact of an asteroid, falling on the Yucatan peninsula 66 million years ago. Image credit: Fabio Manucci.About 66 million years ago, a 10-km-wide asteroid crashed into Earth near the site of the small town of Chicxulub in what is now Mexico.The impact unleashed an incredible amount of climate-changing gases into the atmosphere, triggering a chain of events that led to the extinction of non-avian dinosaurs and 75% of life on the planet.Evidence includes high levels of platinum-group elements (PGEs) like iridium, ruthenium, osmium, rhodium, platinum, and palladium in Cretaceous-Paleogene boundary layers, which are rare on Earth but common in...

Top Stories Tamfitronics Two-dimensional (2D) aurora images with full spectrum have been captured by scientists in Japan using the newly-developed hyperspectral camera for auroral imaging (HySCAI).Keogram of (a) all-sky camera and (b) HySCAI, and (c) time evolution of space-averaged spectrum of aurora emission measured by HySCAI on October 20-21, 2023. Image credit: Yoshinuma et al., doi: 10.1186/s40623-024-02039-y.The aurora is a natural luminous phenomenon caused by interactions between precipitating particles and the constituents of the upper atmosphere.Most of the observed spectrum consists of lines or bands of neutral or ionized nitrogen and oxygen atoms.There is a variety of characteristic colors of aurorae, such as green and red, but there are multiple theories about the emission process by which they appear in different types of aurorae, and to understand the colors of aurorae, the light must be...

Politics tamfitronics In 2019, construction began on a natural gas pipeline that would cut through the unceded homelands of the Wet’suwet’en Nation in western Canada. Wet’suwet’en land and water protectors were forbidden from coming near the construction area operated by Coastal Gaslink, owned by TC Energy. However, the project was met almost immediately with resistance and gained international attention due to the tribe’s use of traditional law. Under Wet’suwet’en law, the pipeline trespassed on Wet’suwet’en land. With no treaty signed with Canada or Britain, Wet’suwet’en argue that their laws are still applicable — a political status recognized by the Canadian supreme court — and they have the right to evict Coastal Gaslink, and its pipeline, from its homelands.In 2021, Chief Dsta’hyl, a Wet’suwet’en...

Politics tamfitronics Edo State Deputy Governor, Philip Shaibu, criticized Governor Godwin Obaseki for failing to acknowledge his reinstatement to office by the court, claiming that he was instrumental in making Obaseki Governor.During an appearance on Channels Television’s political program, ”Politics Today”, on Friday, Shaibu stated that it took former Governor Adams Oshiomhole three months to convince him to support Obaseki’s candidacy.“Obaseki was not a politician, and he was not financially equipped to run for governor. Oshiomhole introduced him, and some of us initially argued against it. But out of respect for Oshiomhole, we eventually agreed to support Obaseki,” Shaibu explained. “It wasn’t Obaseki who made me; I made him. We used our resources, mobilized our friends, and leveraged our political capital to make him governor.”The ongoing conflict between Shaibu and Obaseki stems from issues related...
