In recently published research using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers announced that they had found the first clear detection of a circumplanetary, moon-forming disk surrounding the exoplanet PDS 70c — a first in astrophysics.

The circumplanetary disk, or CPD, has been seen in past research from other groups. However, due to the inability to tell the disk apart from its surrounding environment, the presence of the disk around PDS 70c could not be confirmed.

Until now.

In this podcast, I have invited Daniel Jue, one of the youngest Entrepreneurs of the field of AGI. Daniel is an Independent Artificial General Intelligence researcher at Cognami in the US. He has worked supporting the US Department of Defense, including Data Fusion and analytic development for DARPA, the Defense Advanced Research Projects Agency, whose mission is to prevent technological surprise by potential adversaries. In addition he worked with scientists and engineers at IronNet CyberSecurity, a startup with DARPA and NSA heritage who have recently gone public. In March of 2,021 Daniel took on full time AGI research, drawing upon the fields of Computer Science, Neuroscience, Philosophy and Psychology. Some of his major influences have been Jacques Pitrat’s CAIA (An Artificial AI Scientist) project, Jean Piaget’s childhood development theories and Spiking Neural Networks. He sees a generalizable substrate at the basis for AGI, where engineers design the “physics” in which intelligent behavior could emerge.

Analysis of unique fingerprints in light emitted from material surrounding young stars has revealed “significant reservoirs” of large organic molecules necessary to form the basis of life, say researchers.

Dr. John Ilee, Research Fellow at the University of Leeds who led the study, says the findings suggest that the basic chemical conditions that resulted in life on Earth could exist more widely across the Galaxy.

The large organic molecules were identified in protoplanetary disks circling newly formed stars. A similar disk would have once surrounded the young Sun, forming the planets that now make up our Solar System. The presence of the molecules is significant because they are “stepping-stones” between simpler carbon-based molecules such as carbon monoxide, found in abundance in space, and more complex molecules that are required to create and sustain life.

The study, published in Physical Review Letters, used historic records between 1962–64 from a research station in Scotland. Scientists compared days with high and low radioactively-generated charge, finding that clouds were visibly thicker, and there was 24% more rain on average on the days with more radioactivity.

Professor Giles Harrison, lead author and Professor of Atmospheric Physics at the University of Reading, said: By studying the radioactivity released from Cold War weapons tests, scientists at the time learnt about atmospheric circulation patterns. We have now reused this data to examine the effect on rainfall.

The politically charged atmosphere of the Cold War led to a nuclear arms race and worldwide anxiety. Decades later, that global cloud has yielded a silver lining, in giving us a unique way to study how electric charge affects rain.

The huge “dog-boned” asteroid hurling through the solar system has now been imaged in unprecedented detail.

A team of astronomers has seemingly obtained the best pictures and data to date of the peculiar asteroid, Kleopatra. Using the European Southern Observatory’s Very Large Telescope (VLT), observers from the SETI Institute in Mountain View, California, and the Laboratoire d’Astrophysique de Marseille, France, captured images to help two teams of scientists answer some interesting questions.

“Kleopatra is truly a unique body in our Solar System,” says Franck Marchis, who led a study on the asteroid published in Astronomy & Astrophysics. “Science makes a lot of progress thanks to the study of weird outliers. I think Kleopatra is one of those and understanding this complex, multiple asteroid system can help us learn more about our Solar System.”

The asteroid, which orbits in the central region of the asteroid belt between Mars and Jupiter, was initially discovered on April 10 1880. However, it wasn’t until just 20 years ago that radar observations revealed it had two lobes which were connected by a thick “neck.” In 2,008 Marchis and his colleagues discovered that the asteroid was orbited by two moons, named AlexHelios and CleoSelene, after the Egyptian queen’s children.
