Good morning
In 1977, Voyager 1 left Earth carrying a golden record etched with a map of pulsars rather than of any country, meant to tell whoever finds it how to find us.
Most maps exist for that same reason: to correct someone's wrong idea of where things actually are. Today's edition has a few closer to home: a swimsuit named after an atoll, a mountain far from the mainland and a continent outsized by a single country.
In today's edition
- A swimsuit named after a nuclear test site
- Australia's highest peak tops a smoking volcano
- Brazil outsizes an entire continent

Bikini · Fact of the day
The swimsuit named after a nuclear test site
Say "bikini" and you picture a beach, not a bomb. But the word is a straight-up Pacific place name: Bikini Atoll, in the Marshall Islands, roughly 4,300 km southwest of Hawaii.
On 1 July 1946 the US detonated the 'Able' atomic bomb there as part of Operation Crossroads. Four days later, in Paris, designer Louis Réard unveiled his scandalously small two-piece and named it after the atoll. He was betting the design would land with the same explosive shock as the headlines that week. It worked: the swimsuit outlived the news cycle, and the atoll's name has been sewn into a global wardrobe word ever since.

Mawson Peak, Heard Island
Four thousand kilometres from the Australian mainland, in the southern Indian Ocean roughly halfway to Antarctica, an ice-armored volcano called Big Ben smokes over an island almost nobody has ever set foot on. Its summit, Mawson Peak, rises 2,745 metres: 517 metres taller than Mount Kosciuszko, the peak every atlas prints as Australia's highest.
Heard Island has no airstrip, no town and no permanent residents, only glaciers, elephant seals, and an active vent. The country's true high point is a smoking sub-Antarctic cone, not a gentle alpine walk-up, and it has been climbed only a handful of times.

Indonesia plans a capital beyond Java Nusantara, the planned capital under construction in Borneo rainforest since 2022 to replace sinking Jakarta, lays out government districts in its master plan. Every ministry that relocates there shifts Indonesia's political map away from Java for the first time in the country's history.
Everest's official height, revised A joint resurvey by Nepal and China revised the official elevation of the world's highest peak, a reminder that even the map's fixed points move as satellite geodesy gets sharper. Since then, the two governments have shared one agreed figure instead of competing numbers.
How the Maldives builds land against rising seas The Maldives has been reclaiming land off Malé, adding artificial islands and raising existing ones against sea-level rise, which expands the atoll nation's usable footprint even as its natural land shrinks elsewhere in the archipelago.

A continent, out-continented
Line up the outlines with no latitude grid to cheat by, and the eye still expects the continent to win. It doesn't. Brazil's border alone encloses over 820,000 more square kilometres than the entire island continent of Australia. That's a single country, filed mentally as 'a big South American nation,' outsizing a landmass with its own tectonic plate and its own weather systems. Maps mislead by omission more than by distortion.
