How could this be?
The rock, discovered in Mistastin Lake crater in Canada, was found to reach 4,298 degrees Fahrenheit resulting from an asteroid impact.
And now, a new study used the samples that were gathered between 2009 and 2011 and confirmed the record-breaking heat of the stone. The rocks are known to be formed during a meteorite impact that also formed the Mistastin Lake crater approximately 36 million years ago.
As a result of this coincidental discovery, it has been found that the rock contains zircons, an incredibly durable mineral that condenses under high heat. Additionally, the researchers have found a mineral called reidite that forms in the condition of zircons undergoing high temperatures and pressures.Reidite allows researchers to estimate the level of pressure - estimated between 30 and 40 gigapascals - caused by the impact.
The results of this research may be used to study different craters brought from other planets, especially the Moon.The production of superheated melt during hypervelocity impact events has been proposed to be a common occurrence on terrestrial planetary bodies. Recent direct evidence of superheated impact melt temperatures exceeding >2370°C from the Kamestastin impact structure, Canada, was based on a single impact glass sample.

Hubble probes extreme weather on ultra-hot Jupiters -- ScienceDailyAstronomers have discovered bloated Jupiter-sized worlds that are so precariously close to their parent star they are being roasted at seething temperatures above 3,000 degrees Fahrenheit. That's hot enough to vaporize most metals, including titanium. They have the hottest planetary atmospheres ever seen. Hubble astronomers are reporting on bizarre weather conditions on these sizzling worlds. It's raining vaporized rock on one planet, and another one has its upper atmosphere getting hotter rather than cooler because it is being 'sunburned' by intense ultraviolet (UV) radiation from its star.
