Search for intelligent aliens explores new radio-frequency realms
A new European search for extraterrestrial radio signals at low, uncharted frequencies is underway, having already listened to over 1.6 million star systems. SETI, the search for extraterrestrial intelligence, has traditionally focused on radio frequencies higher than a gigahertz, such as the hydrogen-line frequency at 1.42 GHz. SETI astronomers tend to shy away from lower…

NASA Tech Breathes Life Into Potentially Game-Changing Antenna Design
Some 30 years ago, a young engineer named Christopher Walker was home in the evening making chocolate pudding when he got what turned out to be a very serendipitous call from his mother. Taking the call, he shut off the stove and stretched plastic wrap over the pot to keep the pudding fresh. By the…

Venus’s atmospheric nitrogen explained by ancient plate tectonics
Abstract Venus is the least understood of the terrestrial planets. Despite broad similarities to the Earth in mass and size, Venus has no evidence of plate tectonics recorded on its young surface, and Venus’s atmosphere is strikingly different. Numerical experiments of long-term planetary evolution have sought to understand Venus’s thermal–tectonic history with indeterminate results. However,…
