From New Scientist:

Something has smashed into Jupiter, leaving behind a black spot in the planet's atmosphere, scientists confirmed on Monday.

This is only the second time such an impact has been observed. The first was almost exactly 15 years ago, when more than 20 fragments of comet Shoemaker-Levy 9 collided with the gas giant.

"This has all the hallmarks of an impact event, very similar to Shoemaker-Levy 9," said Leigh Fletcher, an astronomer at NASA's Jet Propulsion Lab in Pasadena, California. "We're all extremely excited."

From ABC News:

For Some, Going to the Moon Became a Spiritual, Philosophical Event.

In the history of humanity, only 24 men have shared the experience.

Forty years ago today, the first of the two dozen astronauts to fly to or around the moon rocketed away from Earth to make history. Twelve had the chance to walk on the moon's surface, though only nine of those are still alive today.

When they returned to Earth, they were scientists and explorers with no peers, at the pinnacles of their careers.

But for some the adventure was so epic it changed the course of their lives. Inspired and transformed by seeing Earth shrink to the size of their thumbs, many let new philosophical and spiritual sensibilities guide them. Others chose entirely new career paths.

From The Telegraph:

Apollo 11 reached the moon's surface 40 years ago today with Neil Armstrong and his fellow astronauts Buzz Aldrin and Michael Collins on board. Here are some key quotes from the mission that put the first men on the moon.

"I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." President John F. Kennedy announces his intention to put a man on the Moon before a joint session of Congress on May 25 1961

"No nation which expects to be the leader of other nations can expect to stay behind in this race for space...We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard." John F. Kennedy explains his lunar ambitions in a speech at Rice University on September 12, 1962

2010: A New Space Odyssey Beckons

From The Independent:

The world is on the verge of new manned exploration of the solar system – and, this time, environmentalists are backing it.

This weekend, 40 years after man first landed on the Moon, more human beings than ever before are orbiting on a single spacecraft. In 1969, three men squeezed into Apollo 11's command module, a craft little bigger than a Mini.

Yesterday, the International Space Station, now as large as a four-storey house, yet speeding at 17,239mph, took on board the crew of the shuttle Endeavour: 12 men, one woman – seven Americans, two Russians, two Canadians, one Japanese and a Belgian. During a two-man space-walk, the crew added a four-ton porch – an outdoor shelf for experiments – to the station.

From Yahoo News/AP:

WASHINGTON – The measure of what humanity can accomplish is a size 9 1/2 bootprint. It belongs to Neil Armstrong, the first man on the moon. It will stay on the moon for millions of years with nothing to wipe it away, serving as an almost eternal testament to a can-do mankind.

Apollo 11 is the glimmering success that failures of society are contrasted against: "If we can send a man to the moon, why can't we ..."

What put man on the moon 40 years ago was an audacious and public effort that the world hasn't seen before or since. It required rocketry that hadn't been built, or even designed, in 1961 when President John F. Kennedy declared the challenge. It needed an advance in computerization that had not happened yet. NASA would have to learn how to dock separate spaceships, how to teach astronauts to walk in space, even how to keep them alive in space — all tasks so difficult experts weren't sure they were possible.

July Eclipse Is Best Chance To Look For Gravity Anomaly

From New Scientist:

From remote observatories on the Tibetan plateau to a cave in a Shanghai suburb, Chinese researchers are poised to conduct an audacious once-in-a-century experiment. The plan is to test a controversial theory: the possibility that gravity drops slightly during a total eclipse.

Geophysicists from the Chinese Academy of Sciences are preparing an unprecedented array of highly sensitive instruments at six sites across the country to take gravity readings during the total eclipse due to pass over southern China on 22 July. The results, which will be analysed in the coming months, could confirm once and for all that anomalous fluctuations observed during past eclipses are real.

WASHINGTON (AFP) - - Forty years after Alan Bean became the fourth man to walk on the moon, the now 77-year-old former astronaut still likes to share his memories of space flight with a broad audience -- by painting them.

Bean decided to make the switch from astronaut to artist a dozen years after the Apollo 12 mission that took him to the moon in November 1969 and after spending two months in space in 1973 on board Skylab, and his souvenirs from both missions dominate his artwork.

When, at age 49, he dropped a bombshell on his bosses and colleagues at NASA, telling them that he was leaving to become a full-time painter, they wondered if he wasn't in the throes of lunacy.

Cornell ecologist Nelson Hairston Jr. is a pioneer in a field known loosely as "resurrection ecology," in which researchers study the eggs of such creatures as zooplankton -- tiny, free-floating water animals -- that get buried in lake sediments and can remain viable for decades or even centuries. By hatching these eggs, Hairston and others can compare time-suspended hatchlings with their more contemporary counterparts to better understand how a species may have evolved in the meantime.

Arctic Mystery: Identifying The Great Blob of Alaska

Alaska's North Slope. Ccourtesy North Slope Borough

From Time Magazine:

A group of hunters aboard a small boat out of the tiny Alaska village of Wainwright were the first to spot what would eventually be called "the blob." It was a dark, floating mass stretching for miles through the Chukchi Sea, a frigid and relatively shallow expanse of Arctic Ocean water between Alaska's northwest coast and the Russian Far East. The goo was fibrous, hairy. When it touched floating ice, it looked almost black.

But what was it? An oil slick? Some sort of immense, amorphous organism adrift in some of the planet's most remote waters? Maybe a worrisome sign of global climate change? Or, as folks wondered who followed from faraway via the internet, was it something insidious and, perhaps, even carnivorous like the man-eating jello from the old Steve McQueen movie that inspired the Alaska phenomenon's nickname?

From L.A. Times:

The young scientists who created the Saturn V rocket that powered Aldrin and Armstrong to the moon on Apollo 11 in July 1969 were the unsung heroes in the space race with the Soviet Union.

It wasn't a young president's brash promise that enabled Neil Armstrong and Buzz Aldrin to take those first halting steps on the lunar surface 40 years ago Monday. Nor was it the courage of the astronauts themselves.

The success of America's big bet in space depended on the ability of young, unheralded engineers to build rocket engines that were both powerful enough and reliable enough to wrench the spacecraft from Earth's jealous grasp and send it winging to the lunar surface.

From Live Science:

Biologists have found microbes that live in the hottest, coldest, driest and most unpleasant places on Earth. Many of these bugs don't adapt well to new surroundings, but one microbe is remarkable for withstanding a wide range of conditions. This quality might make this unique organism suitable for adapting to life on Mars.

This ultimate survivor is called Methanosarcina barkeri. It is found in freshwater and marine sediments, and other places where oxygen is scarce. Because it breathes out methane, researchers are interested to see if it — or some other "methanogen" — could be responsible for the methane that was detected in the martian atmosphere in 2003.

Expiration Dates

From Organize Your Life:

Certain items in your house practically scream “toss me” when their prime has passed. That mysterious extra white layer on the Cheddar? A sure sign it needs to be put out of its misery. Chunky milk? Down the drain it goes.

But what about that jar of olives or Maraschino cherries that has resided in your refrigerator since before the birth of your kindergartner? Or the innumerable nonedibles lurking deep within your cabinets and closets: stockpiled shampoo and toothpaste, seldom-used silver polish? How do you know when their primes have passed?

With help from experts and product manufacturers, Real Simple (http://www.realsimple.com/) has compiled a guide to expiration dates. These dates are offered as a rough guideline. The shelf lives of most products depend upon how you treat them. Edibles, unless otherwise indicated, should be stored in a cool, dry place. (With any food, of course, use common sense.) Household cleaners also do best in a dry place with a stable temperature. After the dates shown, beauty and cleaning products are probably still safe but may be less effective.

10 Stunning (And Useful) Stats About Twitter

From Information Marketing Blog:

Last month a social media analytics provider named Sysomos released a comprehensive report on Twitter usage. The problem with most analysis on Twitter, though, is that it is limited by the minimal amount of data that Twitter collects. So, to fill the gaps, most reports do things like guessing gender based on real names or pulling data from keywords in people's biographic information. This often yields some questionable results - and the Sysomos report is not immune to this (for example, they find that 65% of Twitter users are under the age of 25, but base this on only the 0.7% of users who actually disclose their age).

Red Sky At Night: Heavens Turn Crimson Over Britain After Russian Volcano Erupts

(Click Image to Enlarge)
Shepherd's delight: A particularly fiery red sky over fields in Leicestershire last night after an eruption at Sarychev Peak in Russia unleashed a colourful mixture of ash and sulphur. When this 'volcanic aerosol' in the stratosphere mixes with the red light of the setting sun, it produces a vivid crimson hue

From The Daily Mail:

The night skies over Britain will turn a deep shade of crimson this week as the fallout from a Russian volcano blast hits the UK.

Millions of tonnes of dust, ash and sulphur dioxide were thrown up to 30 miles into the air when Sarychev Peak on Matua Island in the Kuril Archipelago erupted last month.

The blast created what experts call a ‘volcanic aerosol’ - a colourful mixture of ash and sulphur compounds - in the stratosphere.

This scatters an invisible blue glow which, when mixed with the red light of the setting sun, produces a ‘volcanic lavender’, or vivid crimson/violet hue.

Man And Machine The Real Legacy Of The Moon Race

From Boston.com:

For the millions who watched the grainy television feed from the moon on July 20, 1969, Neil Armstrong’s small step seemed to herald a new era. Arthur C. Clarke had already predicted that the children born during the Apollo missions would one day have their passports stamped on the moon; in the lunar spectacle, we glimpsed a brighter future in which humans would conquer the vastness of space and acknowledge their brotherhood on the pale blue dot of the home planet.

And yet, 40 years on, the Apollo program looks less like the start of a new era and more like an ancient culture that flourished briefly and then vanished, leaving only ruined towers, ritual costumes, and incomprehensible glyphs. In the decades since the last towering Saturn V tore through the night sky, NASA’s astronauts have spent their time on modest missions closer to home. The age of easy space travel that Apollo seemed to promise never materialized. And for all its technological marvels, Apollo bequeathed little to our material culture besides instant orange drink, freeze-dried ice cream, and the statuettes of the MTV video music awards.

From Houston Chronicle:

It had all come down to three men sitting atop a 363-foot Saturn V rocket.

In the eight years since President John F. Kennedy stunned the spaceflight community and issued his challenge to put a man on the moon, NASA had spent $25 billion — akin to $140 billion-plus, today — and employed more than 300,000 technicians in its race against the Russians.

The result of these labors sat on a pad at Launch Complex 39A.

At 8:32 a.m. Houston time July 16, 1969, the rocket's engines fired, and the Apollo 11 crew — Neil Armstrong, Buzz Aldrin and Michael Collins — shook, rattled and reached orbit 12 minutes later.

Four days hence, with the planet watching from 240,000 miles away on television signals delayed by 1.3 seconds, Armstrong guided the lunar module Eagle to the surface of the moon. Then he uttered words that would make the city of Houston famous around the world:

“Houston, Tranquility Base here. The Eagle has landed.”

Apollo 11 Moon Landing Footage Enhanced Hollywood Style

From The Telegraph:

It may have been a giant leap for mankind, but it was recorded for posterity in dark, fuzzy footage that has never quite lived up to importance of the occasion.

However, now, with a little help from Hollywood, man's first steps on the moon can be seen in suitably discernible, if not pristine, quality.

To commemorate the 40th anniversary of the Apollo mission and Neil Armstrong's historic stride down from the ladder of a lunar excursion module, NASA has released an enhanced version of the television footage first broadcast to an audience of half a billion.

Mysterious, Glowing Clouds Appear Across America’s Night Skies

From Wired Science:

Mysterious, glowing clouds previously seen almost exclusively in Earth’s polar regions have appeared in the skies over the United States and Europe over the past several days.

Photographers and other sky watchers in Omaha, Paris, Seattle, and other locations have run outside to capture images of what scientists call noctilucent (”night shining”) clouds. Formed by ice literally at the boundary where the earth’s atmosphere meets space 50 miles up, they shine because they are so high, they are lit by the sun longer than the Earth’s surface.

Moon Landing Tapes Got Erased, NASA Admits

From Yahoo News/Reuters:

The original recordings of the first humans landing on the moon 40 years ago were erased and re-used, but newly restored copies of the original broadcast look even better, NASA officials said on Thursday.

NASA released the first glimpses of a complete digital make-over of the original landing footage that clarifies the blurry and grainy images of Neil Armstrong and Buzz Aldrin walking on the surface of the moon.

The full set of recordings, being cleaned up by Burbank, California-based Lowry Digital, will be released in September. The preview is available at http://www.nasa.gov.

NASA admitted in 2006 that no one could find the original video recordings of the July 20, 1969, landing.

Weaving The Way To The Moon

Don Eyles says getting a job on the Apollo mission was probably the greatest stroke of luck in his life (Archive footage: MIT and Nasa)

From The BBC:

As Apollo 11 sped silently on its way to landing the first men on the Moon, its safe arrival depended on the work of a long-haired maths student fresh out of college and a computer knitted together by a team of "little old ladies".

Now, 40 years after Apollo 11 landed Neil Armstrong and Buzz Aldrin on the Moon, the work of these unsung heroes who designed and built the Apollo Guidance Computer (AGC) is back in the spotlight.

"I wasn't so aware of the responsibility at the time - it sort of sunk in later," said Don Eyles, a 23-year-old self-described "beatnik" who had just graduated from Boston University and was set the task of programming the software for the Moon landing.

Not Only Dogs, But Deer, Monkeys And Birds Bark To Deal With Conflict

From Science Daily:

ScienceDaily (July 15, 2009) — Biologically speaking, many animals besides dogs bark, according to Kathryn Lord at the University of Massachusetts Amherst, but the evolutionary biologist also says domestic dogs vocalize in this way much more than birds, deer, monkeys and other wild animals that use barks. The reason is related to dogs’ 10,000-year history of hanging around human food refuse dumps, she suggests.

In her recent paper in a special issue of the journal, Behavioural Processes, Lord and co-authors from nearby Hampshire College also provide the scientific literature with its first consistent, functional and acoustically precise definition of this common animal sound.

40 Years After Moon Landing: Why Aren't People Smarter?

Being smart involves being able to understand the relationships between events, finding and questioning hidden assumptions, and so on. The fact is, most students are not taught how to think analytically and critically. Image Credit: stockxpert

From Live Science:

Editor's Note: Forty years ago this month, humans landed on the moon for the first time. We asked Benjamin Radford why, four decades later, humans have not become any smarter.

A look at old periodicals reveals something very interesting about human nature. Newspapers and magazines from the early 1900s were full of advertisements for instant weight loss gizmos, miracle cures, and all other forms of self-evident quackery. A century later, this stuff is still being advertised — and lots of people are buying.

You would think that by now people would know that you can't lose 10 pounds a week taking a "breakthrough" miracle pill, and you can't earn $50,000 a week working from home in your spare time (at least not legally).

World's Oldest Tattoos Were Made Of Soot

From New Scientist:

For those inclined to put ink to flesh, modern tattoo parlours offer dizzying arrays of dyes – mercury-containing reds, manganese purples, even pigments that glow in the dark.

Getting inked wasn't always quite so complicated, however. A new analysis concludes that the world's oldest tattoos were etched in soot.

Belonging to Ötzi the 5300 year old Tyrolean iceman, the simple tattoos may have served a medicinal purpose, not a decorative one, says Maria Anna Pabst, a researcher at the Medical University of Graz, Austria, who trained optical and electron microscopes on biopsies of Otzi's preserved flesh.

What’s In Earth Orbit And How Do We Know?

Tracking all the active satellites and orbital debris around the Earth is a challenging task, even for the US Defense Department. (credit: NASA)

From Space Review:

Whenever the topic of space debris and satellites in orbit comes up a lot of numbers tend to get thrown around by a lot of different people, and it can be hard to keep all the figures straight. Compounding this is the superficial knowledge (at best) of the subject by many media commentators and the tradition of secrecy by the US military, the organization that has historically been the main keepers of the data on space debris.
