☆ Massive explosions from the sun pose a radioactive triple threat to the moon, Earth, and Mars
  + stars: | 2023-08-09 | by ( Maiya Focht | ) www.businessinsider.com   time to read: +5 min
An explosion from the sun blasted radiation into space, reaching the Earth, Mars, and the moon in 2021. These particles cannot harm humans on Earth, but they may harm people in space, research shows. These are called coronal mass ejections, and a particularly intense one produced particles that hit Mars, Earth, and the moon in October of 2021. That's why his team is in near constant communication with the Space Radiation Analysis group. In the future, similar safeguards could be established on the moon and Mars.

☆ The sun is growing more active, which could shower the moon with lethal doses of radiation and threaten the lives of astronauts who dare set foot on it

An explosion from the sun blasted radiation into space, reaching the Earth, Mars, and the moon in 2021. These are called coronal mass ejections, and a particularly intense one produced particles that hit Mars, Earth, and the moon in October of 2021. If there had been an astronaut up on the moon or Mars at the time these particles hit, they would've been exposed to radiation, though the levels were below a lethal dose. As the sun begins entering a more active stage, CMEs will likely become more common and stronger, which means more radiation risk for astronauts. That's why his team is in near constant communication with the Space Radiation Analysis group.

☆ Northern Lights Are Seen in Places Where They Normally Aren’t

The sky over an unusually wide swath of the northern hemisphere lit up with a brilliant display of color overnight into Monday morning, dazzling people across North America and Europe. The display was potentially visible as far south as Iowa in the United States, as well as in parts of southern England, scientists said. The phenomena, known as the aurora borealis or northern lights, occurs when particles emitted by the sun collide with particles that are already trapped around Earth’s magnetic field, and can often be seen from parts of Iceland, Canada and Alaska. But on Friday, the sun let off a large burst of energy, said Robert Steenburgh, a space scientist with the Space Weather Prediction Center at the National Oceanic and Atmospheric Administration. (These bursts are also known as coronal mass ejections.)
