There are definite interrelations between the spacings of the planets – they are much more than giant rocks randomly flying through space. There is order and a scheme, a cosmic dance of the planets as some romantics like to say.
An astronomical year for me ….When I was in the third grade I suddenly became very interested in everything astronomical – especially the planets of our local solar system. That same year we studied the Solar System in public school, and that only added to my excitement over the topic. I began badgering my parents to buy me a telescope...
It is tempting to say that any well-educated person should know what it takes to be scientifically literate. But what does scientific literacy really involve? Given that scientific literacy is a key goal of most science education standards and frameworks, considerable ink has been dedicated to utilizing the term in pedagogical papers.
Africa’s astronomical debut has come at an opportune time, as a multitude of facilities and projects have taken root across the continent in the service of astronomical questing.
Co-hosted by The Galactic Inquirer, a free online journal on diverse astronomical topics, the American Astronomical Society, North America’s largest organization of astronomers, the International Astronomical Union’s Office...
Astronomy encompasses the fields of Planetary Science (including Earth as a planet), Heliophysics, Astrophysics, Astrochemistry, Astrobiology, Cosmology, and Cosmogony – the study of cosmic origins. Astronomy, in turn, is informed by the core sciences of Physics, Chemistry, and Biology. It both depends upon and helps to advance technological innovation...
Each year, the American Astronomical Society (AAS) hosts two big meetings in January and June that span all of astronomy and its subfields of cosmology, helioastronomy, and planetary science. The COVID-19 pandemic took its toll, beginning in June 2020, when the meeting format pivoted to online presentations. The January 2022 meeting was canceled outright, but by June 2022, the society pivoted again, offering a hybrid mix of in-person and online formats. These two meetings underscored the unquenchable thirst for astronomical questing among our veteran and rising scientists. Here are a few highlights from these meetings.
Fast Radio Bursts are flashes of radio emission lasting for several milliseconds. The time of arrival of signals depends on the radio frequency, called the dispersion measure (DM), which depends on the environment through which the signals travel, specifically the number of free electrons in their path. Very few FRBs have matches with sources observed at other wavelengths (Wikipedia - Fast Radio Burst).
Blue wavelengths of light are damaging to many forms of life, and glare from unshielded light compromises road safety and infiltrates bedrooms, suppressing melatonin production, undermining sleep quality and duration, and exacerbating susceptibility to many kinds of illness...

“It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it?” -- Richard Feynman (1918 – 1988)
