NASA’s “Space Poop Challenge” is paying for your thoughts on upgrading its crappy system

If you’re an innovative person with ideas about how best to deal with your bodily functions while wearing a spacesuit, then NASA wants to hear from you! The agency is currently soliciting entries in its aptly titled Space Poop Challenge, posted on the website HeroX, to “source a system that routes and collects human waste away from the body” for “fully-suited astronauts.” 

What’s more, it pays. The innovator with the winning design gets $30,000. 

Right now, astronauts use space toilets when they’re out of their suits and diapers when they need to wear their spacesuits during launch and entry, but diapers are usually only worn for a matter of hours. They’re also uncomfortable, and keeping waste next to your body for long periods of time can lead to irritation and infection.

Stephen Hawking says humans have 1,000 years to leave Earth

Famed theoretical physicist Stephen Hawking has some grim news for humanity: We have 1,000 years to get off Earth or we’re totally screwed.

The 74-year-old Hawking delivered a speech on Tuesday at the Oxford Union, reported the Daily Express, in which he said “I don’t think we will survive another 1,000 years without escaping beyond our fragile planet.” Hawking reportedly said that humans are speeding towards the end of our time on Earth by destroying and using up its resources — and eventually, it will be impossible for us to continue living here.

The launch was 3:20 p.m. EST Thursday, which was early Friday morning at the Baikonur cosmodrome in Kazakhstan.

At 56, astronaut Peggy Whitson is a lot younger than John Glenn was when he flew in a space shuttle at 77, but when Whitson launched Thursday with two other crew members toward the International Space Station she became the oldest female astronaut in the world to fly into space.

Can You Spare A Zeptosecond? Scientists Have Just Measured The Shortest Unit Of Time Ever

A millisecond is a thousandth of a second, and a nanosecond is a billionth of a second, but there’s another measurement of time that makes both of them look slow. 

Scientists have for the first time been able to measure something in a zeptosecond, or a trillionth of a billionth of a second.

Laser physicists in Munich fired an extreme ultraviolet light pulse onto a helium atom to excite the electrons, causing one to break free ― a process called photoemission. At the same time, they shot an infrared laser pulse to detect the electron as it left the atom.

That’s when it happened.

Massive ‘Pillars Of Destruction’ Show Stars Destroying Their Own Formation Clouds

It’s an act of violence on a cosmic scale. 

New images from the European Southern Observatory’s Very Large Telescope in Chile showed the massive “Pillars of Destruction” in the Carina Nebula, some 7,500 light years from Earth:

ASSOCIATED PRESS

The images revealed a “nursery” of new stars, which were wiping out the very clouds from which they formed. 

“In an ironic twist, one of the first consequences of the formation of a massive star is that it starts to destroy the cloud from which it was born,” the ESO wrote in a news release. 

That destruction led to scenes that looked like the cover of a 1960s psychedelic album. Some of the nicknames even sounded like the titles of those albums, such as the Mystic Mountain, a formation of gas and dust that spans more than three light years:

A Supermoon Like This One Won’t Come Again Until 2034

On Nov. 14, skywatchers will be treated to a supermoon so big and bright that it’s being billed as a “super-dupermoon” or an “extra-supermoon.”

Supermoons aren’t especially uncommon, but this will be the nearest that a full moon has come to Earth since January 26, 1948. The full moon won’t get this close again until November 25, 2034.

The term supermoon refers to a full moon that occurs when our planet’s natural satellite is at its closest point to Earth in its elliptical orbit. Astronomers call that point perigee, and so “perigee moon” is another term for supermoon. (The point at which the moon is most distant from Earth in its orbit is known as apogee.)

A supermoon can appear up to 14 percent bigger and 30 percent brighter than an apogee full moon, according to NASA. The effect is most pronounced when the moon is viewed near the horizon.
