"The Blue Age" in bookstores now. Starred review, Kirkus: "Outstanding." Suitably quirky All Predictions Wrong now at Substack. TMQ has returned in same place.
Trump just called for a big commitment to U.S. shipbuilding. Yet another instance of ripped-from-the-pages-of-today’s-headlines for my 2021 book THE BLUE AGE.
Over 1000 years ago, Persian astronomer Abd al-Rahman al-Sufi published humanity’s oldest known record of the Andromeda Galaxy in "The Book of Fixed Stars" (Bodleian Library MS. Marsh 144 p. 167).
800 years later, Andromeda became the 31st entry in Charles Messier’s "Catalogue of Nebulae and Star Clusters".
From “a small cloud” to “nebula” and now known to be our nearest major galaxy, Andromeda has remained a fundamental astronomical object.
Today’s image, taken over 202 hours, shows how far we have come in our ability to observe our neighbor. The diffuse red and blue clouds are mostly foreground ionized hydrogen and oxygen well within our Milky Way.
Pink-red clouds of hydrogen ionized by the energetic light of young stars trace the galaxy’s dusty spiral arms. M32 and M110 are satellite galaxies pictured orbiting the larger Andromeda.
Despite its long history of observation through ancient unaided eyes to modern telescopes, Andromeda still holds countless secrets that astronomers will continue to search for, including how galaxies merge and evolve, as well as the nature of the dark matter that galaxies reside in.

Stalin thought medical science should be able to keep him alive indefinitely. The Doctors Plot persecutions were triggered by his anger that doctors could not reverse aging. https://t.co/bfsChLLRkx via @WSJ
Mitt Romney to Harvard Business School graduates: "There's more to a country than its economy. To be a great nation, it must also be a good nation. The world needs good men. It needs good women. Good leaders. Good parents raising good children. There is no national success that could compensate for failure to be a good and noble people."
Musk’s mega-rocket had its 12th flight. Starship is a fascinating project but flight did not reach orbit.
Seems unlikely as NASA claims that 2027 will see an Artemis III mission in which a crew practices the rendezvous maneuver with a Starship in orbit.
News flash – EVERY public school teacher or sports coach spends his or her own money to help students. Kudos to Teddy Bridgewater! https://t.co/4VDeC19KUh
