One stretch of Western Australia turned green enough for Landsat to see. Wildflowers reached giant radio telescopes

At a separate observatory, flowers reached the telescopes

The ground photographs come from Inyarrimanha Ilgari Bundara, CSIRO's Murchison Radio-astronomy Observatory on Wajarri Yamaji Country, about 500 miles northeast of Perth. NASA places the Landsat scene about 370 miles north of Perth. They document the same regional season, not one confirmed exact location.

White pom pom flowers crowded around one of ASKAP's 36 dishes, while purple mulla mulla rose in front of the array. Pink Calandrinia mirabilis and red Swainsona formosa, called marluguru in Wajarri, added color across the red ground.

Andrew Whitmarsh, CSIRO's land manager at the observatory, said dormant seeds responded to the early winter rain and produced the strongest display he had seen since 2008. Different plants usually favor different conditions, he said, but many varieties flowered together this season.

The observatory helped document more plant populations

Radio-astronomy infrastructure occupies about 0.2 percent of the observatory site, according to CSIRO. The organization's land team works with Western Australian biodiversity specialists to monitor plants across the formerly pastoral property.

One result involves Calandrinia mirabilis. The species had been listed as Priority 1 in Western Australia. It moved to Priority 3 in 2025 after additional populations were documented at the observatory.

That change does not mean the plant has become common or that its future is secure. It means researchers now know it occurs in more places than the earlier record showed.

The green followed the old water paths

The newer satellite image was captured on August 30, 2026, by the Operational Land Imager aboard the NASA-USGS Landsat 8 satellite. It shows vegetation spreading across a part of the Murchison region about 370 miles north of Perth.

The brightest green traces branching riverbeds. The image does not resolve individual flower heads; it records the broader vegetation response across the landscape.

Two wet months changed the palette

June was wetter than usual across much of southern Western Australia, and August brought another wet turn. The Bureau of Meteorology recorded a statewide June average of 30.1 millimeters, 12 percent above the 1961 to 1990 norm, followed by 24 millimeters in August, 62 percent above the norm. Cold fronts, troughs and low-pressure systems carried August rain across the state's west, south and interior.

Those are statewide figures, not measurements for the Landsat scene or the observatory. They establish the wet backdrop to two separate views of the season, one from orbit and one on the ground farther northeast.

The scene may not return next year

Whitmarsh does not expect the same display next year. Blooms in dry country depend on rain arriving in the right places at the right time.

For one August, white flowers reached the telescope dishes while, elsewhere in the Murchison, green traced dry channels clearly enough for Landsat to see.
