“Once an axion is detected,” astrophysicist Raymond Co at the University of Minnesota wrote in an email to The Daily Galaxy, “the implications to cosmology will be profound. For instance, signals from experiments with different search strategies will determine whether the axion is dark matter. If it is, with the measured axion properties, one can narrow down its possible cosmological origins.
“I wouldn’t be surprised if Planet Nine has already been imaged in one of the large sky surveys currently underway, but, if not, it will be hard for it to hide from the Vera Rubin Observatory once it starts operations in a few years,” Caltech’s Michael Brown told The Daily Galaxy. Brown, along with Caltech’s Konstantin Batygin, presented the first evidence that there might be a giant planet tracing a bizarre, highly elongated orbit through the outer solar system in 2016.
“Mars does like to keep its secrets,” Elizabeth Sklute at the Planetary Science Institute, observed in an email to The Daily Galaxy about packing up the first Martian rock samples as the NASA Perseverance Mission begins its sample return mission. “We sent Mossbauer, and found the oxides were nanophase, and that Mossbauer was inconclusive,” Sklute noted.
“Planet Earth Report” provides descriptive links to headline news by leading science journalists about the extraordinary discoveries, technology, people, and events changing our knowledge of Planet Earth and the future of the human species. It’s been another fascinating week on our little blue dot from Neil deGrasse Tyson wanting to go ice fishing on Europa to our moon is leaving us, and we can’t stop it.
Astronomers may soon have the answer to what is perhaps the greatest mystery of modern science –is dark energy a uniform force across space and time, or has its strength evolved over eons?
As life has evolved its complexity has increased exponentially, just like Moore’s law, which states that the number of transistors on an integrated circuit doubles approximately every two years. The regression suggests that if life takes 10 billion years to evolve to the level of complexity associated with homo sapiens, then we may be among the first, if not the first, intelligent civilization in the Milky Way, negating Drake’s Equation.
This weekend’s “Galaxy Report” ranges from the fragile lifespan of technological civilizations to Stephen Hawking’s ‘lost’ Nobel Prize to probing for life on Saturn’s moon, Titan to colonizing Mars could accelerate human evolution.
