A new study has found that the Chicxulub asteroid that caused the mass extinction of dinosaurs may have had
This is an 8.5 kilometer wide impact crater that was found by scientists recently and has been named Nadir. It is believed to have been caused by an asteroid hitting the earth and is said to have happened around the same time as the Chicxulub impact crater. If this is confirmed, it means that the dinosaurs may have died from two asteroid hits.
The thought that the Chicxulub asteroid may not have been solely responsible for the extinction of dinosaurs is a controversial one. Some scientists believe that there may have been another factor involved in the mass extinction. Veronica
Nearly 200 impact craters have been discovered on Earth, the vast majority of which are on land. The reason for this is because impact craters at sea gradually become buried under sediment. The Nadir structure is a valuable scientific find, regardless of its birthdate.
Uisdean Nicholson, a geologist at Heriot-Watt University in Edinburgh, discovered a large impact crater while analyzing data collected by seismic waves. The crater, which is under nearly 1 kilometer of water, has a bowl-shaped structure with a broken-up, terraced floor and a pronounced central peak. These features are typical of
In a new study, researchers have analyzed the size and impact of the asteroid that created the Vredefort Crater in South Africa – and their findings suggest that it was even bigger than previously thought. The Vredefort Crater is the largest and oldest confirmed impact crater on Earth, and
Nadir, the asteroid that hit Earth around 466 million years ago, was much smaller than Chicxulub, the asteroid that caused the dinosaurs' extinction. Though the Nadir impact would have been devastating, it wouldn't have had global effects, according to
A new study has found that the Nadir asteroid may have formed around the end of the Cretaceous period, 66 million years ago. The asteroid is adjacent to the Chicxulub asteroid, and the two may have been ripped apart by gravitational forces during a previous Earth flyby. This new information could help explain the mass extinction that occurred at the
The recent study published in the journal Science has left some experts skeptical of its conclusions. The study suggests that a structure on the surface of Mars is an impact crater, but geologist Philippe Claeys of Vrije Universiteit Brussel in Belgium says that there is not enough evidence to confirm this. He points out that the structure could just as easily be a collapsed volcanic caldera or a salt diapir, and
The age of the Nadir structure is unknown. The seismic data shows that it may have formed during the Cretaceous period or later. However, this is only an estimate. Drilling in the crater for minerals that contain radioactive elements could provide a more precise date of formation.
It’s not the first time that scientists have investigated whether Chicxulub had an accomplice. Some studies have suggested that the Boltysh crater in Ukraine may have formed at the same time as Chicxulub, though researchers have since determined
Bray and her colleagues are currently in the process of negotiating funding in order to collect samples from the crater. Their hope is to drill in 2024, which would settle some of the debate surrounding Nadir's origins. However, Bray says that even if they are able to prove that Nadir is the sister of the "dinosaur killer", new
