Lagrange Points When I was in high school physics class learning about gravity, I recall wondering if we could determine the size, or at least the mass, of the universe by calculating how much gravitational pull the planet “feels.” If the planet is tugged more in one direction, could we determine where we are in […]
James Webb Space Telescope If you’ve followed the newsletter from the early days, you’re well familiar with the Hubble Telescope and its myriad astronomical contributions. Some of the most resplendent images of the universe have come from the famed telescope. One might argue all of the most gorgeous imagery of the cosmos to date has

Total Eclipse of the Orb Much of the world recently received a cosmic treat. Just this morning, a nearly-full lunar eclipse waltzed across the firmaments. Despite covering more than 97% of the moon with shadow, that figure made this event technically a partial eclipse. More than making up for that 3% sliver, however, was

The Sirens of Titan Join me on a trip toward the outer reaches of our solar system. On the voyage, we’ll mix metaphors from two fantastic authors. I think the conflation we’ll make might be acceptable to one of them. Maybe both! In 1959, Kurt Vonnegut published his second novel. Setting the tone for his

Aurora The Valkyrior [Valkyries] are warlike virgins, mounted upon horses and armed with helmets and spears. /…/ When they ride forth on their errand, their armour sheds a strange flickering light, which flashes up over the northern skies, making what Men call the “aurora borealis”, or “Northern Lights”. — Thomas Bulfinch, Mythology Sorry, Disney fans, we do
The Sky Really Is Falling Chicken Little – originally known as Henny Penny – took a lot of flak for constantly touting the end of the world. If you watched the news over the preceding weekend and looked to the skies, you might be forgiven for giving Chicken Little a bit of a reprieve. Space

The Unaccountable Freak & the Comet I think it’s fair to say no comet is as popular in the collective consciousness as Halley’s Comet. Every once in a while another will pop up, such as Hale-Bopp, which garnered a lot of attention in 1997 due to the cult called Heaven’s Gate, or last year’s spectacular NEOWISE.

Uranus Stinks Way back in Issue 25 we discovered Uranus is tilted and you probably should have seen a doctor. Nearly a year later, it seems you let the problem fester and things are even worse. Now, you notice something foul coming from Uranus. A rank odor seems to emanate from Uranus. Uranus smells like rotten
The Winter Solstice Hallelujah! Today marks the Winter Solstice in the Northern Hemisphere. The shortening of daylight is finally over. For the next six months, our sunlight durations will only increase. Despite speaking of the solstice as a date, it is actually a moment. Precisely, the solstice is the moment one of our planet’s poles is tilted
