Where do cosmic rays come from?
Earth is under constant bombardment by cosmic rays, showers of high-energy particles that blast our planet from all directions at near light speed.While this might sound like the precursor to a sci-fi alien invasion, it is a real phenomenon that scientists have...
Can astronomers do their work during the day?
Radio telescopes, such as the dishes of the Very Large Array in New Mexico, can observe during daylight hours. Credit: Alex Savello/NRAO Can we study the universe in the daytime? It seems astronomical observations usually happen at night. Rishi VardhanPatna,...
How Could Laser-Driven Lightsails Remain Stable?
It’s a long way to the nearest star, which means conventional rockets won’t get us there. The fuel requirements would make our ship prohibitively heavy. So an alternative is to travel light. Literally. Rather than carrying your fuel with you, simply attach your...
