The effects of a possible act of energy sabotage are visible from space.

On Tuesday (Sept. 27), European leaders reported the discovery of three separate leaks in two Baltic Sea pipelines known as Nord Stream 1 and Nord Stream 2, which were built to carry natural gas from Russia to Germany. 

The leaks sent methane gas streaming to the Baltic Sea surface, creating bubbly white patches that look somewhat like churning hurricanes. On Monday (Sept. 26), a tiny Earth-observing satellite managed to spot one of these dramatic signatures — the patch above the Nord Stream 2 breach, which lies just southeast of Denmark's Bornholm Island. (The other two leaks are in the Nord Stream 1 line.)

That satellite is a Dove, a cubesat built by Planet. The San Francisco company currently operates a fleet of about 200 Doves, each of which is just the size of a shoebox but can resolve features as small as 10 feet (3 meters) on Earth's surface.

The Dove probably saw evidence of sabotage, according to some European leaders. It would be very unlikely for two pipelines to spring three leaks nearly simultaneously without human intervention of some sort, researchers and government officials have said. And seismologists recorded powerful explosions near the leak sites on Monday (Sept. 26), which hardly seems like a coincidence.

It's unclear at the moment who's responsible for the explosions and what they were intended to achieve (if indeed they were intentional). Investigations are planned but cannot get fully underway until the breaches are repaired, experts have said.

Tensions between Russia and the West have been high since Russia invaded Ukraine in February. The United States and other nations, including many in Europe, have responded to the ongoing aggression with a series of economic sanctions against Russia. 

Russia is a major energy producer, and it has traditionally sold much of its natural gas to Europe. Russia had been sending natural gas to Europe via Nord Stream 1 but stopped the flow in August, according to Reuters

"The new Nord Stream 2 pipeline had yet to enter commercial operations," Reuters added. "The plan to use it to supply gas was scrapped by Germany days before Russia began what it calls a 'special military operation' in Ukraine in late February."
