The giant planets in our solar system—Jupiter, Saturn, Uranus, and Neptune—have challenged our understanding of planetary formation and evolution. Specifically, their atmospheric formations and compositions have provided awe-inspiring images from spacecraft and given scientists key insights into the interior mechanisms of these massive worlds. But what about exoplanets? What can their atmospheres teach scientists about their formation, evolution, composition, and interior mechanisms? And how do longstanding exoplanet models stack up against the real thing?

Scientists have created tiny “optical tornadoes” — swirling beams of light that twist like miniature whirlwinds — using a surprisingly simple setup based on liquid crystals. Instead of relying on complex nanotechnology, the team used self-organizing structures called torons to trap and manipulate light, causing it to spiral and rotate in intricate ways. Even more impressively, they achieved this effect in light’s most stable, lowest-energy state, making it far easier to generate laser-like beams with these unusual properties.

A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped inside a nucleus. This exotic state may reveal how mass is generated, suggesting that particles can weigh less when surrounded by dense nuclear matter. The findings support long-standing theories about how the vacuum of space influences mass.

In the chaotic first moments after the Big Bang, ripples in spacetime may have done more than just echo through the cosmos—they could have helped create dark matter itself. New research suggests that faint, ancient gravitational waves might have transformed into particles that eventually became the invisible substance shaping galaxies today.

It turns out that even after studying our solar system in depth and discovering more than 6,100 exoplanets across more than 4,500 exoplanetary systems, not all solar systems are created equal. The longstanding notion is that planets orbit almost entirely in the same orbital path, also called an orbital plane. But what if an exoplanetary system was found to have exoplanets that not only orbit in different planes, but also exhibits changing behavior regarding when they pass in front of their star?

The Moon has played a huge role in the development of Earth. It stabilizes the planet, tempered dramatic climate swings, and possibly even provided the tidal heating that might have led to the first life forms. So it’s natural we would want to find a similar Earth/Luna system somewhere else in the cosmos. But astronomers have been searching for one for years at this point to no avail. And a new paper from Emily Pass and her colleagues at MIT, Harvard, and the University of Chicago describes using the James Webb Space Telescope to track some of the most promising exomoon candidates - only to be foiled by the star they were orbiting.

The new Colibre cosmological simulation includes more critical detail than previous simulations. It also includes updated models of things like AGN feedback and star formation. The simulations also include a sonic component, giving the results a cinematic and information-rich flair.

Measuring the strength of gravity is extraordinarily difficult, and different experiments have always disagreed – but a new test is paving the way to finally understanding nature’s most enigmatic force

This week’s Jesus and Mo strip, called “bite2”, is new but came out a bit late on Wednesday.  In response to last week’s criticism of Islam, Mo now gets the chance to make fun of Christian ritual.  He does a good job, but Jesus gets the last word.

Much of visual astronomy requires nothing more than clear skies, keen eyes, and patience. If you’re out skywatching Saturday evening and live in North or South America, watch for the waxing gibbous Moon pairing with Regulus at dusk. For a privileged region, the Moon will actually blot out or occult the star, in one of the best-placed lunar occultations of a bright star for 2026.

A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar cataclysm. After detecting ripples in space-time, scientists spotted a fast-fading red glow that initially looked like a rare kilonova—the kind of collision that forges gold and uranium. But just days later, the signal shifted, behaving more like a supernova, leaving researchers puzzled. Now, some think they may have witnessed something never seen before: a “superkilonova.”

It was a lazy day today, with one visit to an architectural/history site and then one big and delicious meal.  After we had a leisurely breakfast and did our ablutions, it was nearly 11 a.m.  We then walked the ten blocks to the Owens-Thomas House and Slave Quarters:

The Owens–Thomas House & Slave Quarters (originally known as the Richardson House) is a historic home in Savannah, Georgia, that is operated as a historic house museum by Telfair Museums. It is located at 124 Abercorn Street, on the northeast corner of Oglethorpe Square. The Owens–Thomas House was designated a National Historic Landmark in 1976, as one of the nation’s finest examples of English Regency architecture.

Renovations in the 1990s uncovered and restored one of the oldest and best preserved urban slave quarters in the American South.

. . . The house is notable for its early cast iron side veranda with elaborate acanthus scroll supports on which the Marquis de Lafayette addressed the citizens of Savannah on his visit in 1825.

The house was built between 1816 and 1819, designed by the architect William Jay of Bath and financed and occupied by Richard Richardson. It was then purchased by attorney and politician George Welshman Owens, who was briefly mayor of Savannah and later a U.S. Representative.

The Owens family lived in the house for a while, but after some decades turned it into a boarding house, which is when Lafayette stayed there on his final visit to America on the 50th anniversary of the American Revolution—in which Lafayette played a huge role.

In 1951 the family turned the house over to the Telfair Academy of Arts and Sciences , which still owns it (I visited the other two parts of the Museum on my first day here).

The sign below gives pretty much the same information above.

The front of the house (I forgot to photograph the famous balcony).  When Lafayette, an abolitionist, visited Savannah in 1825, the town kept all the slaves inside, along with the free blacks, so they wouldn’t be incited by Lafayette’s antislavery sentiments.

The back garden of the house, designed to be completely symmetrical. In the rear are the slave quarters.  This is only part of them: the small house held 12 people, and there were a bit more than 20 enslaved people working for the white residents.

This sign was in the slave quarters, explaining why the guides and many of the signs used the terms “enslaved people” instead of “slaves.”

Inside the quarters, which slept at least twelve people, though many of the enslaved, like the cook and those who took care of the chlldren, slept inside the big house.

The dining room.  Food was cooked in the basement, and since there was no dumbwaiter it was carried on trays up two floors from the basement and put in the butler’s pantry before being served.

The butler’s pantry was a small room, with four empty bottles of wine sitting on the sideboard. As the tour moved on, I picked up one of the bottles and saw what’s below: a bottle of Barton and Guestier bordeaux—from 1870! I’d never held a wine bottle that old before.  And this chateau is still going strong; it was founded in 1725.

The structural material of the house was tabby, an equal mixture of sand, burnt oyster shells, water, and ash. It was an early form of concrete, and was quite durable. As you see, the tabby was covered with wood paneling.

This room was presumed to be the library/study, though now they’re unsure what all the rooms were used for.

This is presumed to be the oldest son’s bedroom.

And a mirror, at the bottom of which you can see a selfie of Professor Ceiling Cat (Emeritus):

The (presumed) master bedroom, now a word that’s out of favor for obvious reasons (I can’t remember what it’s supposed to be called now).

After the tour we walked home and then got in the car to drive to a restaurant I’d scoped out as a likely prospect: great food, not overly expensive and, most important, Southern. Yes, we went to Erica Davis Lowcountry.  It turned out to be all I hoped for, though if you drove by this place you wouldn’t think to go in. But you’d be making a mistake if you didn’t.

We split two appetizers. First, oysters Rockefeller made with local oysters. Wikipedia describes the dish this way:

Oysters Rockefeller is a dish consisting of oysters on the half-shell that have been topped with a rich sauce of butter, parsley and other green herbs, bread crumbs, and then baked or broiled.

There were also collard greens, cream. and Parmesan cheese.  It was scrumptious—the first time I’ve had this dish. With all that garnish you could still taste the oysters, and I love oysters. You’d think the dish would be too busy with all the ingredients, but the flavors mingled perfectly.

Another Southern classic: fried green tomatoes, these with feta cheese and balsamic vinegar reduction.

The menu was so full of good stuff (see the link above) that I asked the waiter what she recommended. Without question she mentioned the shrimp, which are local, fresh, and delicious. So I got a half pound of boiled shrimp. They came with clarified butter, shrimp sauce, and two sides (I chose cheese grits and deep-fried okra).  And oy, were those shrimp good! I ate the shells, of course, as all good shrimp lovers do.

Tim had the Wassaw redfish, described as “pan-seared redfish filet, garlic beurre blanc, heirloom tomato, stone ground grits, fresh green beans.” He pronounced it excellent.

Betsy had two crab cakes along with green beans and cole slaw. As expected, the cakes were almost all lump crabmeat, with just a small amount of filling to hold them together. With a little bit of the sauce on the crab, it was a Platonic version of this dish.

And my Southern dessert: the third helping of banana pudding I’ve had on this trip—this time served in a Mason jar. This was the fanciest version of all I’ve had.  As you can see, it’s topped with whipped cream dusted with vanilla wafer crumbs, with a whole wafer on the side. (Banana pudding sans vanilla wafers is unthinkable.) Then there’s a layer of banana pudding, then a layer of cake, and then a bottom layer of pudding with chunks of banana. This was the best version I had on this trip, and probably the best version I’d ever had. (I’ve eaten it many times, often with BBQ or a meat-and-three plate in the South.)

The meal was terrific, not very expensive, and prepared with great care. I’d recommend this place very highly to anyone who visits Savannah.
