A blue fireball exploded in the Tasman Sea
Researchers captured an astonishing video when a green asteroid exploded over Tasmania, southern Australia.
Investigator research vessel, operated by Australia’s national science agency, CSIRO, captured this fireball as it plunged through Earth’s atmosphere, tore across the sky and then crumbled into small fragments on the Tasman Sea. Eyewitnesses to the meteor said that it was green in color with the naked eye.
A meteorite in Michigan
In January 2018, a meteor exploded over the town of Hamburg, Michigan, causing debris to fall into a frozen lake below. After careful analysis of the remaining meteorites, scientists discovered they contain thousands of organic compounds formed billions of years ago.
These compounds themselves have also been around since the early days of the Solar System. This means that asteroids that crashed into Earth, when our planet was young, could carry similar compounds.
Billions of years ago, organic asteroid compounds could be incorporated into primitive microorganisms, the team said. So studying the Michigan meteorite could give us a glimpse of early life on the planet.
Rainbow meteorites were found in Costa Rica
In 2019, a rainbow-colored meteorite exploded in the skies of Costa Rica. The scientists then found fragments of this meteorite in the two villages La Palmera and Aguas Zarcas.
After looking at the specimens, the researchers said they could contain the chemical constituents of life. Unlike other asteroids that fell on Earth, this rainbow-colored meteorite was once part of a larger meteorite, which was formed from dust from an ancient nebula. It is this nebula that later ‘nurtured’ our Solar System.
It is known that meteorite fragments found in Costa Rirca contain complex carbon compounds, which may include amino acids, which can combine together to form proteins and molecules such as DNA.
The comet’s debris may have leveled an old village in Syria
The prehistoric village of Abu Hureyra in northern Syria was inhabited by the first known peasants on Earth.
But then, a mysterious explosion completely destroyed the area, leaving most of the ruins with thatched huts covered in carbon. When excavating the remaining remains, the researchers also found glass balls formed from molten earth, samples of molten iron and sulfur, and nano diamonds.
Scientists recently examined these glass materials more closely and found that they can only form at temperatures above 3,630 F (2,000 C). The team concluded that debris from a comet while passing through Earth plunged into our planet’s atmosphere, before exploding in the sky above the village, releasing a scorching heat wave. the village and the soil below it.
Meteors plunged into Earth at the ‘supernatural’ angle, completely wiping out dinosaurs
66 million years ago, a meteorite estimated to be 81 km in diameter crashed into Earth at the most dangerous angle possible, leaving the dinosaur completely extinct.
It is known that in order to learn more about this disaster, researchers at Imperial College London decided to use a supercomputer provided by HP to create a simulated 3D model of the collision. happened 66 million years ago. The results of the simulation model study showed that the meteorite collided with the Earth at an angle of 60 degrees. This impact angle produces the maximum of climate change gases such as sulfur and carbon dioxide, compared with shallow or near vertical impact angles.
Accordingly, the huge amount of gas released from the collision completely eclipsed the Sun, creating a “nuclear winter” phenomenon that caused the Earth to enter the Ice Age. The change in the environment, the sudden changes in temperature, the decrease in food sources, combined with the toxic atmosphere made 75% of all life on Earth, including dinosaurs, completely destroyed.
SpaceX’s spaceship unexpectedly exploded during testing
On December 10, SN8 – the newest prototype of the Starship that is expected to send humans to the Moon and Mars in the near future took off from SpaceX’s testing facility in Texas.
The ship started its Raptor engine and flew straight to a height of 12.55km. However, the SN8’s test flight lasted only 6.5 minutes, before a crash during the landing caused the missile to explode and be completely destroyed when it hit the ground.
In fact, this test of Starship has obtained many positive results compared to previous tests. Specifically, the SN5 and SN6 models of Starship only performed test flights at an altitude of 152.4 m. The SN8 prototype was the first to be equipped with a nose tip, flaps along the body and three new generation Raptor engines.
