How the Strongest Solar Flare in a Decade Is Affecting Earth

How the Strongest Solar Flare in a Decade Is Affecting Earth

“The monster burst of radiation already caused brief radio blackouts and may trigger strong auroras in the coming days. Early Wednesday morning, the sun unleashed two monster solar flares, the second of which was the most powerful we’ve seen in more than a decade. The burst of radiation was so intense, it caused high-frequency radio blackouts across the daytime …

Spacewalking cosmonauts release 3-D-printed satellite

Spacewalking cosmonauts release 3-D-printed satellite

“Spacewalking cosmonauts set free the world’s first satellite made almost entirely with a 3-D printer on Thursday. In total, Russians Fyodor Yurchikhin and Sergey Ryazanskiy ended up releasing five nanosatellites by hand. One by one, the tiny craft — no more than 1 to 2 feet in size — tumbled safely away from the International Space Station. The exterior casing of …

Four Earth-sized planets detected orbiting the nearest sun-like star

Four Earth-sized planets detected orbiting the nearest sun-like star

“A new study by an international team of astronomers reveals that four Earth-sized planets orbit the nearest sun-like star, tau Ceti, which is about 12 light years away and visible to the naked eye. These planets have masses as low as 1.7 Earth mass, making them among the smallest planets ever detected around nearby sun-like stars. Two of them …
