Elon Musk and his Starlink Internet service, according to a US general, are responsible for keeping Ukrainian communication links up despite Russian attempts to shut them down. In a June 8 Politico piece, Brig. Gen. Steve Butow, head of the space portfolio at the Defense Innovation Unit, the Pentagon’s Silicon Valley tech outpost, said: “The strategic consequence is that it completely devastated [Russian President Vladimir] Putin’s media campaign.”

“He has never been able to quiet (Ukrainian President Volodymyr) Zelenskyy to this day.” Elon Musk, the billionaire entrepreneur, and his SpaceX firm are working on a satellite network and Earthbound receivers that will beam the Internet throughout the world, reaching locations that previously couldn’t access high-speed internet. The messages going between Earth’s receivers and a “constellation” of satellites flying approximately 342 miles above the surface, according to the business, are quicker than fiber-optic networks and can reach more distant parts of the world.

Musk sent the equipment to Ukraine in March after authorities there requested them after Russia’s incursion on February 24, according to the Washington Post. “While you try to colonize Mars — Russia try to occupy Ukraine! Russian missiles strike Ukrainian civilians while your rockets successfully land from space ” Mykhailo Fedorov, Ukraine’s Vice Prime Minister, sent Musk a tweet on February 26. ” We request that you deliver Starlink stations to Ukraine and address sane Russians to stand.”

“Throughout our history, we’ve always had to find ways to stay ahead,” Kim told Rest of World. “Automation is the next step in that process.”

Speefox’s factory is 75% automated, representing South Korea’s continued push away from human labor. Part of that drive is labor costs: South Korea’s minimum wage has climbed, rising 5% just this year.

But the most recent impetus is legal liability for worker death or injury. In January, a law came into effect called the Serious Disasters Punishment Act, which says, effectively, that if workers die or sustain serious injuries on the job, and courts determine that the company neglected safety standards, the CEO or high-ranking managers could be fined or go to prison.

There are a handful of ways to produce hydrogen fuel without emitting carbon into Earth’s atmosphere. One involves using electricity to split water into hydrogen and oxygen.

This method, known as electrolysis, requires a catalyst that speeds up chemical reactions that occur within hydrogen fuel cells.

More often than not, this electrocatalyst is platinum, a metal so rare that it’s typically more expensive than gold, which makes the production process more costly than traditional sources of renewable energy and fossil fuels.

Hoag’s Object is a galaxy with an central region and a bright outer ring, but lacks any intervening material.

No. 7: With This Ring, I Thee Puzzle.

In 1950, astronomer Arthur Hoag came upon a tiny, faint, 16th-magnitude ring surrounding a ball-like center, and reasonably assumed it was a planetary nebula — a nearby puff of gas expelled from a single old-aged star. He also proposed an alternative and far more exotic explanation that this was an “Einstein Ring” from a faraway quasar. In this scenario, the quasar’s light is distorted into a halo by space-warping caused by a massive foreground spherical galaxy that it seems to surround. But later spectroscopic studies rejected this because the golden central ball and the blue ring have exactly the same redshift, indicating a whopping rush-away speed of 7,916 miles (12,740 kilometers) per second, which proves they’re both located exactly the same distance from us.
