For more than three centuries, astronomers asking whether the Solar System is stable have received ever more comforting answers. Isaac Newton was not so sure. He suspected that the mutual tugs between Jupiter and Saturn would eventually wreck the planetary order, and that only divine intervention could prevent it. By the late 1700s, Laplace and […]

Physicists have been asking an awkward question for decades. If the universe is built from invisible fields, why has each one ended up in the state we find it in, and not in some other? A team at the University of Portsmouth, working with colleagues at Syracuse University and the École Normale Supérieure in Paris, […]

Long ago, the patch of sky that would become our galactic neighbourhood looked nothing like a galaxy. It was a collection of thousands of smaller galaxies. Some were turning out stars at a frantic pace, others held nothing but gas, and others were littered with dead stars and black holes. That is the picture drawn […]

In April 2009, newspapers around the world ran a headline that read like a cocktail menu: the center of the galaxy tastes of raspberries and smells of rum. The line came from the Guardian, which built it from a press release by the Max Planck Institute for Radio Astronomy in Bonn. The release was much […]

An international team of astronomers has published a detailed study of VT J1906+0849, a radio source discovered in the VLASS survey (Very Large Array Sky Survey) that doesn’t resemble anything else previously catalogued in the Milky Way. The paper, led by Jessie M. Miller of the California Institute of Technology, combines radio, infrared, optical, and […]

For the first time, astronomers have pointed NASA’s two flagship space telescopes at the same patch of sky beyond Neptune and let them work as a team. Hubble handled the visible light. Webb handled the infrared. Together, they picked out 27 previously unknown trans-Neptunian objects, or TNOs — small, icy bodies that drift in the […]

Picture a moonless night, far from any city. Look straight at the point in the sky opposite the Sun — the antisolar point, where the Sun would appear if you could see it through the Earth. There, faintly, you might make out an oval-shaped glow, 8 to 10 degrees across. For scale, that’s roughly the […]

A man named Donald Liebenberg tops eclipse-chaser-log.com with a whopping 2 hours, 27 minutes, and 41 seconds of darkness from 27 total eclipses—stats I didn’t even know people tracked until I read Rudi Zygadlo’s piece. It turns out there’s a dedicated subculture of umbraphiles logging every second of totality. Zygadlo meets a veteran British couple who’ve built their lives around these fleeting events, then travels to Spain in August 2026 to see his own first total eclipse. Adding 1 minute 38 seconds to the board earns him a place near the bottom, but judging by the awe he feels in those brief moments of darkness, he may be moving up the league yet.

There are various eclipse-chasing guests in our hotel. You can identify many of them from themed caps and T-shirts. The largest party is an alumni group from UCLA. We meet several by the pool. A couple from Minnesota, a sommelier from New York. “I was in Montreal for 2024,” says Mees from the Netherlands, treading water. “My wife is a virgin.” Everyone is friendly, but somewhat shifty when it comes to the issue of where to watch. We are too.

By 6pm on the day of, we are stationed on the infernal hillside, on a dusty path beneath pine trees and an immaculate sky. There are better vantage points but we have some degree of privacy here. We can hear others, but we can’t see them. The partial phase begins with a yodel at 7:34pm when the sun is eight degrees — or a fist’s length — above the horizon and my father-in-law produces a bottle of local white, which immediately turns warm in the glass. The nibble of the moon turns into a bite then into a crescent and I’m surprised how well my bottom-of-the-range bridge camera with a solar filter over the lens captures the partial phases. Later I’ll wish I never turned the thing on. Meara is quiet. Glowing. She is more pregnant than ever.

A team of archaeologists, led by the University of West Bohemia (UWB), has brought to light, near the town of Chleby, in present-day Czech Republic, a monumental structure dating back more than 6,500 years, identified as one of the oldest ritual centers in Central Europe. The first datings on organic material recovered at the site […]
