Every Wednesday, we’re asking a what-if question – how would our world be different if something were changed? Today’s question is from QSFer Scott: Scientists say we have about five billion years before the sun is likely to explode. But what if we found out it was happening in the next 12-24 months?

WHAT IF: A Solar Storm Destroyed the Internet?

Solar Storm - NASA

The sun is always showering Earth with a mist of magnetized particles known as solar wind. For the most part, our planet’s magnetic shield blocks this electric wind from doing any real damage to Earth or its inhabitants, instead sending those particles skittering toward the poles and leaving behind a pleasant aurora in their wake. But sometimes, every century or so, that wind escalates into a full-blown solar storm — and, as new research presented at the SIGCOMM 2021 data communication conference warns, the results of such extreme space weather could be catastrophic to our modern way of life.

SPACE: Titan’s Largest sea is Really Deep, Too

Titan - NASA

NASA’s epic Cassini mission at Saturn is still generating valuable scientific data more than three years after its demise. Data from one of the spacecraft’s last flybys of Titan, a large moon with the precursors of life’s chemistry, reveals that a huge lake on the surface called Kraken Mare is more than 1,000 feet ( 300 meters) deep — that’s roughly the equivalent of the height of New York City’s Chrysler Building. In fact, the lake is so deep that Cassini’s radar couldn’t probe all the way to the bottom. Back in 2014, preliminary data from this flyby suggested that … Read more

SPACE: Astronomers Discover “Arches of Chaos” in the Solar System

A vast network of invisible energy structures have been discovered in the solar system — a celestial superhighway that future space probes might use to explore far-away corners of solar space. These hidden energy structures, called manifolds, emerge in space-time due to the gravitational interaction of massive objects like the planets, said Nataša Todorović, a mathematician at the Serbian Belgrade Astronomical Observatory and lead author of a paper on the discovery. While astronomers have long known about such pathways, and even used them to navigate our celestial neighborhood, the new study has revealed a new shape in these manifolds: “arches … Read more
