Silent but deadly galaxy killer — Across the universe, galaxies are literally getting the life sucked out of them. A team of researchers at the International Centre for Radio Astronomy Research in Western Australia has examined 11,000 galaxies using the Sloan Digital Sky Survey and Arecibo Legacy Fast ALFA survey. The team concluded that a process called ram-pressure stripping — which forces gas out of galaxies — is more common than previously imagined. It’s a quick death, because without gas, galaxies are unable to produce more stars. The group’s findings were published on January 17th in the Monthly Notices of the Royal Astronomical Society.

Cassini gets a look at Saturn’s wavemaker moon — Saturn’s tiny moon friend, Daphnis, is finally getting its close-up. In a stunning new image [in detail, above] from NASA’s Cassini spacecraft, the elusive moon can be seen peeking out from within the Keeler gap of Saturn’s rings. According to NASA, the image was taken in visible (green) light by Cassini’s narrow-angle camera.
~ It creates waves, unlike the other 61 moons of Saturn.
Venus’ atmospheric commotion — An infrared camera aboard the Japan Aerospace Exploration Agency’s Venus-orbiting Akatsuki spacecraft spotted lazy pockets of atmosphere on Venus in December 2015. Akatsuki’s camera brought the first hard evidence: an enormous, 6000-mile bow-shaped region hanging over a mountainous region of Venus.

NASA director explains what 2016’s temperature changes mean — To understand where we are – and more importantly, where we’re headed – Gavin Schmidt, Director of the NASA Goddard Institute for Space Studies, said we should be focusing on data that shows how much the Earth has warmed since the Industrial Revolution. According to NASA, the global temperature has increased 1.7 degrees F since 1880.
Over that same time frame, carbon dioxide levels have dramatically increased, from roughly 280 to 405.25 parts per million: the highest they’ve been in 650,000 years.
Meanwhile, ‘rogue’ scientists have been struggling to save climate data from that supreme idiot Trump, who has just become the most powerful idiot in the world.
Gizmodo reckon’s Trump’s Age of Ignorance threatens humanity.
~ A former friend of mine was still insisting, a year ago, that global warming was a ‘left wing plot’. I asked him what he thought the left would gain from such a plot. His answer was …. he didn’t have an answer, of course. But the fact remains that people’s wish that this wouldn’t be happening seems to be enough for them to decide it isn’t. It’s not about the causes, really, but what we can do to slow it, for all our futures.
Airbus promises flying car — Airbus last year formed a division called Urban Air Mobility to explore concepts such as a vehicle to transport individuals or a helicopter-style vehicle that can carry multiple riders. The aim would be for people to book the vehicle using an app, similar to car-sharing schemes. (Meanwhile, look at Wired’s outstanding cars of the last year.)
Scientist finally figures out why zebras are striped — Camouflage? No; social recognition? no; lion’s eye shapes? No …
