Radio whistles are first clear sign of Mars lightning Scientists have reported the first clear evidence of lightning on Mars. Using data from NASA’s MAVEN mission, they detected a type of radio wave called a whistler. On earth, whistlers are created by lightning strikes and get their name because they sound like a descending whistle...

How do astronauts return from space and survive re-entry? | Explained
The ascent of a launch vehicle is a battle against gravity to gain the immense velocity required to stay in orbit — while re-entry is a struggle against the atmosphere to shed that same energy in a systematic way. Initially, aerospace scientists believed that surviving atmospheric re-entry would be impossible because the massive kinetic energy...

What water turning to vapour and the way AI learns have in common
Artificial intelligence (AI) models like ChatGPT, Claude, and Gemini often give the impression that there’s a mind at work within the machine. These days they “think” in response to queries, go back and correct themselves, apologise for mistakes, and mimic many tics of human communication. There’s no direct physical evidence to this day that a...

Why are scientists studying gypsum in the Salar de Pajonales?
One of the best places to practice hunting for life on Mars could be in the Atacama Desert in Chile. Scientists recently studied the Salar de Pajonales, an incredibly dry and freezing salt flat located 3.5 km above sea level. Together with the fact that it is blasted by ultraviolet radiation, the Salar is a...
