#199
09/22/2026

Supernovae keep galaxies churning A new study led by Fan Yi Meng from Tsinghua University provides the first comprehensive census of superbubbles in the Andromeda Galaxy, revealing that clustered supernova feedback is sufficient to sustain galactic-scale turbulence. This finding helps to explain why galaxies remain active over billions of years, with turbulence playing a crucial role in regulating star formation rates. The research, published in Nature Astronomy, highlights the energy balance between supernovae and the turbulence they create.Neutrinos may dictate stellar explosions A paper from Mariam Gogilashvili and Irene Tambora at the Niels Bohr Institute ex...

The Planet That Keeps Shrinking plus the Weekend Wrap episode artwork
#192
09/12/2026

Today's episode — The Weekend Wrap, Saturday 12 September 2026: OUR LEAD: A SMALLER MERCURY Mercury has been contracting for four and a half billion years as its huge iron core cools, and it writes the record on its own surface — in long lobe-fronted cliffs called lobate scarps, where one slab of crust has ridden up over another. Add up all that shortening and you get the total contraction. The trouble was that the surface record always gave a smaller number than thermal models predicted. New work led by Gaku Nishiyama at the German Aerospace Center in Berlin, published in G...


Half the Neutron Stars

#191
09/11/2026

Today's episode — S05E191, Friday September 11, 2026: Main story: A population-synthesis study published in Nature Astronomy on 10 September argues that magnetars make up roughly half of all neutron stars, not the one-in-a-hundred implied by the catalogues. Celsa Pardo-Araujo and Nanda Rea (Institute of Space Sciences, ICE-CSIC, Barcelona) with Michele Ronchi (ASTRON) and Vanessa Graber (Royal Holloway) modelled the whole isolated-neutron-star population as one family rather than four separate classes, evolving spin-down, magneto-thermal decay and Galactic dynamics together, then filtering the simulated population the way real surveys filter the sky. Of the 24 known neutron stars younger than 2,000 years, magnetars and central compact ob...

09/10/2026

Today's episode — S05E190, Thursday September 10, 2026: Main story: 109 fast radio bursts have been used to measure how much galactic feedback has smoothed out the matter in the universe. A fast radio burst lasts about a millisecond, and on its way to us it is dispersed — low radio frequencies slowed more than high ones by free electrons along the path, exactly the way a prism separates white light. The size of that delay counts the ordinary matter the burst passed through. Writing in Nature Astronomy on 8 September, a team led by Kritti Sharma at Caltech, with Vikram Ravi, Liam Connor and Elis...

09/09/2026

Everything beyond Neptune is a leftover. The icy bodies of the Kuiper Belt never got assembled into a planet, and out there — dark, cold and empty enough that things mostly leave each other alone — they are the closest thing we have to the original building blocks of the solar system, still sitting roughly where they were made. The trouble is that everything we know about them, we learned from the big ones. Ground-based telescopes stop at around twenty-five kilometres. In two papers published on 8 September in The Astronomical Journal, teams using Hubble and Webb simultaneously — one telescope in visible light, one in...


The Moon in Five Hours

09/08/2026

For fifty years the story has been that the Moon assembled slowly out of a disc of debris. New simulations from Southwest Research Institute add one thing everybody left out — the strength of rock — and get an intact Moon in about five hours. Plus eight black holes that outgrew their galaxies, two massive stars that fell past each other and got caught, Dragonfly's Titan landing site gets a name, and today's daylight occultation of Jupiter.

09/02/2026

Today's episode — S05E183, Wednesday September 2, 2026: Main story: A thermal anomaly beneath Mars's south pole. Writing in Nature on August 27, a team led by Alexander Berne (Caltech PhD '26, now University of Arizona) reports that the interior of Mars's southern hemisphere is 200–400 °C hotter than the northern hemisphere and partially molten. The team used tidal tomography — measuring how much the solid body of Mars flexes under the Sun's tidal pull by tracking minute velocity changes in three orbiters (Mars Global Surveyor, Mars Odyssey and Mars Reconnaissance Orbiter) across roughly 25 years of radio tracking data. Hotter, softer rock deforms more, so the deg...

09/01/2026

Today's episode — S05E182, Tuesday September 1, 2026: Main story: SpaceX cleared Booster 21's static fire at Starbase's Pad 2 on August 30, the last major milestone before Starship Flight 14 — the third flight of the Starship V3 design. Ship 41 had already completed its own static fire campaign at Massey's Test Site. Flight 14 will attempt something no Starship flight has done before: catching the ship itself, not just the Super Heavy booster, with the launch tower's upgraded "chopstick" arms. Pad 2 received expanded propellant storage, additional pumps and faster-moving catch hardware ahead of the attempt. The flight follows directly on from Flight 13's Ship 40, which survived a dr...

Today's episode — S05E179, Friday August 28, 2026:   Feature story: US startup Reflect Orbital has FCC approval for Eärendil-1, a demonstration satellite carrying a 60-foot mirror, the first step toward a planned constellation of 50,000-plus orbital mirrors beaming reflected sunlight to Earth on demand. A new peer-reviewed study (Kocifaj, Bakos and Kundracik, accepted at The Astrophysical Journal Letters) finds a full-scale, 174-foot operational mirror would appear about 40 times brighter than the full Moon to anyone standing in its roughly 3.4-mile beam, with measurable sky-glow extending 20-34 km further — astronomer Gáspár Bakos says it would be "worse than big citi...

08/27/2026

Today's episode — S05E178, Thursday August 27, 2026:
Feature story:
Physicists at Lawrence Livermore National Laboratory, led by Marius Millot, used the Omega Laser Facility at the University of Rochester to shock-compress diamond samples to about 1 terapascal — roughly three times Earth's core pressure — and temperatures hotter than the Sun's surface, recreating conditions found deep inside Neptune and Uranus. The results resolve a 20-year, ~1,000-degree disagreement between lab measurements and quantum simulations over diamond's actual melting point, confirming the simulations were right. The team also found diamond stays in its normal crystal structure right up until it melts — no intermediate phase —...

Feature story:
Astronomers using the ALMA array in Chile, led by Bill Dent (European Southern Observatory), have released the most detailed picture yet of the actual surface of Betelgeuse, the red supergiant marking Orion's shoulder — a corrugated, irregular surface with bright convective hot spots, some nearly 1,000°F hotter than the surrounding plasma. One hot spot in the northeastern region has persisted for more than seven years, far longer than current models predict, and its orientation lines up with the position of Betelgeuse B — a companion star imaged for the first time in July...

08/24/2026

Today's episode — S05E175, Monday August 24, 2026:
Main story:
China delays Chang'e-7's launch by about a month. The Chang'e-7 lunar south pole mission's launch window opened today, August 24, but a tropical system (reported as Tropical Depression/Storm Narra) over the Gulf of Tonkin, alongside a cited safety and reliability review, forced a scrub with no immediate new date. Because the mission's landing site — the rim of Shackleton Crater — requires specific solar illumination geometry on top of standard orbital mechanics, its launch windows recur only about once a month for roughly a week at a time, unlike China's earlie...
