Using NASA’s Wide-field Infrared Survey Explorer (WISE), astronomers have catalogued 20 previously undetected galaxies that are so bright they belong to an entirely new class of objects, including one that releases 10,000 times more energy than the Milky Way — even though it’s smaller. »
Chesley Bonestell was born long before the flight of the first airplane, and yet he’s well-known as the most influential people in aerospace art. The painter, designer and illustrator died the year of the Challenger disaster—1986—but not before witnessing humankind embrace space in much the way he’d dreamed. »
Late yesterday, CERN scientists made history by using the most powerful particle accelerator in the world to hurl beams of protons together at the record-breaking energy of 13 TeV (tera-electronvolts) — a full 5 TeV higher than the previous standard. »
This simple device regulates its own temperature. Currently, it does nothing more than that. Still, it’s the kind of ridiculously clever machine that will brighten your day, provided you’re a Wallace & Gromit fan.
Perhaps you’re familiar with the strangeness of supercooled water: It stays liquid well below water’s freezing point until you give it a whack, and bam, it suddenly turns into solid ice. You’re probably less familiar diketopyrrolopyrrole (DPP) derivatives, which has similar but also odder properties. »
Located 1,500 light years away and measuring four light-years across, the gorgeous Medusa Nebula offers a sneak preview of what our Sun will look like when it finally enters into its final death throes.
In a remote stretch of the Pacific Ocean southeast of New Zealand, the broken remains of space stations and robotic freighters litter the ocean floor, four kilometers below the waves. The world’s space agencies call this region the South Pacific Ocean Uninhabited Area. But it’s also called the Spacecraft Cemetery. »
The wall of wind-driven ocean that accompanies a hurricane is called a “surge” for a reason: This isn’t a gentle rising of the water level, it’s violent and destructive—sometimes more so than the hurricane’s winds. This hurricane season, for the first time, the National Hurricane Center will be testing a prototype… »
Glaciers around the world are in retreat, but not Alaska’s Hubbard Glacier. It’s steadily advancing into Disenchantment Bay, threatening to block the entrance to Russell Fjord and disrupt life in the nearby town of Yakutat. »
The U.S. Air Force’s unmanned X-37B shot off into space for the fourth time today. The extreme secrecy shrouding all three previous missions have fueled plenty of conspiracy theories. But for once, we actually have some inkling of what the X-37B will do. »
Our atmosphere is crawling with things called “chemical scavengers.” Inside our body, they can be deadly. Out in the sky, they do very good work. Here’s why you want do chemical scavengers in the atmosphere and you don’t want them anywhere near you. »
Drought and extreme heat may significantly increase the risk of power shortages in the Western U.S. unless its utilities adopt “climate-proofing” measures, according to new research.
Anyone who’s listened to television or radio over the past five decades is intimately familiar with that horrible, chill-inducing noise of the Emergency Alert System. Aside from catching your attention, that nails-on-a-chalkboard screeching serves a useful purpose that calls back to the days of dial-up internet. »
The list of countries that have mounted successful missions to Mars is not exactly long: the U.S. and Russia, as you’d expect, and more recently India. But now the United Arab Emirates has an ambitious plan to enter the race as soon as 2020. »
Spending more time in space requires the right tools for the job — and since these tools need to stand up outside the bounds of our own atmosphere, we have to make new tools.And of course, before they go up into space, they need to be tested. Here’s how — and where — they do it. »
The Fly’s Eye was a crude cosmic ray detector perched on top a Utah mountain in the early 80s and 90s. It’s long obsolete now, but it’ll always have a place in astronomy history: On October, 15 1991, it detected something called the Oh-My-God particle, a cosmic ray going faster than astronomers thought possible. »
Using the OSIRIS camera aboard the Rosetta spacecraft, ESA scientists have discovered a strange formation of what appears to be balancing boulders on comet 67P/Churyumov-Gerasimenko.
Remember a couple of years ago when Texas was in such a deep, seemingly-irreversible drought that experts trumpeted it as the next great megadrought, the likes of which would cause Texas to poof into a pile of dust by the end of the decade? The people currently wading through their living rooms remember. »
