A new star in the sky could be the 'brightest nova of the generation'

The Corona Borealis is located near the constellation Hercules. The position of T CrB is marked with a green dot. This view shows the sky around 2 a.m. local daylight time in mid-April. Please note that the constellations will rise and set at different times throughout the year, but their positions relative to each other

Space weather forecast needs update to protect future Artemis astronauts

The Sun can send out eruptions of energetic particles. Credit: NASA/SDO via AP NASA has set its eyes on the Moon with the aim of send astronauts back to the lunar surface by 2026 and establishing a long-term presence there by the 2030s. But the Moon isn't exactly a habitable place for people. Cosmic rays
