There will be a total eclipse of the Moon visible in the Americas the night of March 13-14 The post Total Eclipse of the Moon Coming Mar. 13-14 appeared first on Andrew Fraknoi - Astronomy Lectures - Astronomy Education Resources.
On January 1, 1925, at a meeting of the American Astronomical Society in Washington, DC, astronomer Henry N. Russell read a paper contributed by a young astronomer named Edwin Hubble (who was too junior to earn a trip across the country from the California observatory where he worked.) In this paper, Hubble announces that he […] The post Celebrating the Centennial of Galaxies January 1 2025 appeared first on Andrew Fraknoi - Astronomy Lectures - Astronomy Education Resources.
Saturday, Dec. 21 will be the winter solstice – the shortest day and longest night of the year, with which we mark the beginning of the winter season in the Earth’s northern hemisphere. It’s interesting to note that the planets Venus and Jupiter do not have seasons like the Earth does. The sunshine any spot […] The post Dec. 21 is Winter Solstice — Why We Have Seasons on Earth appeared first on Andrew Fraknoi - Astronomy Lectures - Astronomy Education Resources.
For those of us who, through the years, have been through wave after wave of uncritical and sensational UFO stories in the media, the current obsession with (and jumping to unwarranted conclusions about) mysterious drones seems all too familiar. As before, untrained observers, even government officials, are describing things in the sky without having much […] The post Drone Madness: Here is the Antidote appeared first on Andrew Fraknoi - Astronomy Lectures - Astronomy Education Resources.
You think you ate too much? No matter how stuffed you were after Thanksgiving (or another celebratory meal), it’s nothing compared to Quasar J0529-4351, which astronomers observed earlier this year to be consuming the mass of our entire Sun EACH and every day!

For my entire career as a neurologist, spanning three decades, I have been hearing about various kinds of stem cell therapy for Parkinson’s Disease (PD). Now a Phase I clinical trial is under way studying the latest stem cell technology, autologous induced pluripotent stem cells, for this purpose. This history of cell therapy for PD […] The post Stem Cells for Parkinson’s Disease first appeared on NeuroLogica Blog.
In math and computer science, researchers have long understood that some questions are fundamentally unanswerable. Now physicists are exploring how even ordinary physical systems put hard limits on what we can predict, even in principle.
