The future of travel beyond Earth.

The Tunguska object vaporised almost entirely in the airburst, so Leonid Kulik's 1920s and 1930s expeditions mapped the event not from a crater but from the radial pattern of felled and scorched trees stretching hundreds of square kilometres from the epicentre

The 1908 Tunguska explosion flattened 2,150 square kilometres of Siberian forest without leaving a crater. Leonid Kulik's expeditions reconstructed the event entirely from the radial pattern of felled trees — and a century later, the airburst remains the largest cosmic impact in recorded human history.

Flora And Fauna

In 1994, a bushwalker abseiling into a sandstone gorge 150 kilometres from Sydney found a stand of trees with knobbly bark and fern-like leaves that turned out to be Wollemi pines, a species known from fossils dating back about 90 million years and presumed extinct for roughly two million years

In September 1994, NSW parks officer David Noble abseiled into a slot canyon 150 kilometres from Sydney and walked past a stand of tall trees with bubbled bark that matched 90-million-year-old fossils — the Wollemi pine, a species presumed extinct since long before the first humans.

Microsoft encodes data as hundreds of layers of laser-etched voxels inside 2mm-thick borosilicate glass, using machine learning models to read it back

Microsoft's Project Silica has written 4.8 terabytes of data into a 2mm-thick sheet of borosilicate glass using femtosecond lasers, encoding it as 301 layers of 3D voxels that machine learning models read back — and accelerated ageing tests suggest the data will still be intact in 10,000 years.

Flora And Fauna

A parasitic crustacean called Cymothoa exigua enters a fish through the gills, causes most of its tongue to degenerate, and then attaches itself to the remaining stump, where it may serve as a mechanical replacement

Cymothoa exigua slips through a fish's gills, drains the blood vessels feeding the tongue until the organ withers away, and then hooks itself into the empty stump — the only known animal that functionally replaces a host organ.
