NASA recently released new pictures of Jupiter, the largest planet in our solar system. The photos were taken by the Juno spacecraft. Many of the black-and-white images, sent back to Earth by Juno, have been colourized by people to better show the clouds swirling around the planet. The Juno spacecraft was launched in 2011. Its mission was “to examine Jupiter’s chemistry, atmosphere, interior structure and magnetosophere,” according to a NASA website. Juno arrived at Jupiter in 2016, looking for “clues to its origin and evolution.” Since that time, it has been orbiting (flying around) Jupiter, taking pictures and sending them digitally back to Earth.
Hundreds of people can walk by your front door every day.
The only time you may notice someone, however, is when they knock. Last week, the universe knocked on Earth’s door.
Thousands of asteroids and meteoroids streak pass planet Earth every year. Some of them enter Earth’s atmosphere where most of them simply burn up—those are called meteors. Any that land on Earth are called meteorites.
When a meteorite landed in the city of Chelyabinsk, Russia last Friday, the world took notice. That’s because it was a particularly large meteorite; one chunk was about the size of a van.
A team of Russian scientists in Antarctica has found an ancient lake buried under more than three kilometres of ice.
The lake – Lake Vostok – has been sealed off from the rest of the world for at least 15 million years.
Scientists think the lake may contain tiny organisms, like bacteria, which are not found anywhere else on earth.
If the organisms exist in the lake, it would be because they have been able to adapt to living in the darkness, saltiness and extreme cold of the hidden lake. In that case, they would likely have developed special features that no other organisms on earth have.
