In June of last year, we published a story on the launch of a brand-new SpaceX mission, Starlink, an ostensible name really that has nothing to do with linking to the stars (whatever that means) rather, it would be more like eclipsing them. This is an update to that story and the news isn’t good … More #Starlink (#SpaceX) Update and It’s Not Good News for #Astronomers
As the country and the world struggles to cope with the Corona Virus, it is instructive to contemplate the words of the late Carl Sagan as he shared his thoughts on the state of the world in 1994. The world was different then in some ways but, in many respects, it remains the same today. … More Thoughts on the #CoronaVirus and The #PaleBlueDot

A total eclipse of the sun occurs when the moon, at “New” Phase, perfectly covers the disk of the sun. Since the moon is 400x smaller than the sun, … More #LatinAmerica’s Great Total Solar #Eclipse of July 2, 2019
As the last vestiges of the winter sky are low in the west at twilight, we look forward to the late spring and early summer sky. With Lyra the celestial harp ascending the northeastern sky towards midnight along with Cygnus and the rich summer Milky Way following close behind, we’re certain that spring is here … More Summer Solstice, 2019
