How to grow a cacao tree at home (2024)
Growing chocolate at home might sound like a wild idea, right? Chocolate originates from cacao trees, which demand a tropical climate, specific growing conditions, and several years to reach maturity in order to flower and fruit to produce cacao pods. However, our CocoTerra founder, Nate Saal, took on the challenge…

Imaging Cygnus a at 8.45 GHz with ATA
Earlier this year, I published a post showing our results of the interferometric imaging of Cassiopeia A and Cygnus A at 4.9 GHz with the Allen Telescope Array . Near the end of July, I decided to perform more interferometric observations of Cygnus A at a higher frequency, in order to obtain better resolution. I chose…
