Why Do We Still Vaccinate? – 25 Questions From A Former Vaccine Advocate

May 19, 2015 / / 0 Comments

Brian Rogers, Prevent DiseaseI used to be pro vaccine. I know the feeling of thinking others were just plain crazy and wrong for not vaccinating their children and themselves. ‘Irresponsible!’ I said when pointing my finger. I’d use the same old arguments about polio and small pox and how vaccines saved us from all those horrible diseases and just swallowing and regurgitating the propaganda I was brought up with. It was only recently, in 2009 that I started question [...]

Sea Salt Discovered on Jupiter’s Moon Europa

May 17, 2015 / / 0 Comments

This image shows a view of the trailing hemisphere of Jupiter's ice-covered satellite, Europa, in approximate natural color. Long, dark lines are fractures in the crust, some of which are more than 3,000 kilometers (1,850 miles) long. Image via Galileo spacecraft in 1996.

Europa is thought to have a subsurface ocean. Salt from this hidden sea might be emerging in long fractures visible in the moon’s crust.



Excerpt earthsky.org


Laboratory experiments have lead to new information about the chemical composition of the mysterious dark material in the long, dark fractures on the surface of Europa, a large moon of Jupiter. Researchers at NASA’s Jet Propulsion Laboratory (JPL) mimicked conditions on Europa’s surface. They now say that the dark material is discolored salt, likely sea salt from below the moon’s icy crust. The journal Geological Research Letters published their study on May 15, 2015.

The scientists say this new insight is important in considering whether this icy moon might be hospitable for extraterrestrial life. The life question is a key one for Europa, since this world is believed to have a liquid ocean beneath its crust. The presence of sea salt on Europa’s surface suggests the ocean is interacting with its rocky seafloor.

Scientists have been intensely curious about Europa since Galileo discovered it in 1610. In recent years, they’ve puzzled over the dark material coating the long, linear fractures on Europa’s observable surface. The material was associated with young terrain on this moon of Jupiter, suggesting that it had erupted from within Europa.
However, the chemical composition of the dark material remained elusive, until now.
Planetary scientist Kevin Hand at JPL led the new study. He said in a statement:
If it’s just salt from the ocean below, that would be a simple and elegant solution for what the dark, mysterious material is.
Europa is immersed radiation from Jupiter’s powerful magnetic field, causing high-powered electrons to slam into the moon’s surface. Hand and his team created a laboratory test that mimicked the conditions of Europa’s temperature, pressure, and radiation exposure. They tested a variety of samples including common salt – sodium chloride – and salt water in a vacuum chamber at Europa’s chilly surface temperature of minus 280 degrees Fahrenheit (minus 173 Celsius). They also bombarded the samples with an electron beam to imitate Jupiter’s influence. 

After several hours – a time period corresponding to over a century on Europa, the researchers said – the salt samples were observed to go from white to a yellowish brown, the color similar to the features on the icy moon. Hand said:
This work tells us the chemical signature of radiation-baked sodium chloride is a compelling match to spacecraft data for Europa’s mystery material.

Until now, telescopic observations have only shown glimpses of irradiated salts. No telescope on Earth can observe Europa’s surface with enough resolution to identify them with certainty. Researchers suggest additional spacecraft observation to gather more evidence.
A visit to this icy world would help answer the most tantalizing questions about Europa. Long believed to have a liquid ocean of salt water below its icy surface, this moon continues to display promising conditions for extraterrestrial life. 

As Europa orbits Jupiter, it experiences strong tidal forces similar to Earth and the Moon. These forces from Jupiter and the other Jovian moons cause Europa to flex and stretch, which creates heat, and results in Europa having a warm internal temperature than it would with just the heat from the Sun alone. 

Recent observable geological activity also creates strong evidence that the subsurface ocean interacts directly with Europa’s rocky interior, making geothermal vents, like those in Earth’s oceans, a strong possibility as well. 

These hydrothermal vent ecosystems on Earth thrive with no energy from the sun. Bacteria, shrimp and crustaceans have all been observed in these extreme environments, surviving on what researchers have deemed chemosythesis.

With Europa’s enormous amount of liquid salt water, essential chemical elements and geological activity, this long discovered icy moon appears to be one of the solar systems most promising locations for habitable requirements for life. 

However, until a devoted spacecraft visit’s, nothing beyond hopeful speculation can be proven, the researchers say.

Bottom line: Researchers at NASA’s Jet Propulsion Laboratory created laboratory conditions that mimicked those on Jupiter’s large moon Europa, to learn the chemical compositions of the material in long, dark fractures in the moon’s surface. They now believe this material is sea salt, which has emerged to Europa’s surface from its liquid ocean below.

Are Aliens Finding Ways to Communicate With Humans From Deep Space? NASA intercepts strange “Alien Sounds”

May 8, 2015 / / 0 Comments




dailytimesgazette.com


The recent alien hunting projects of several teams might be another failure, but some unusual sounds were captured by a balloon experiment set up by NASA, which they think could possibly come from another alien life.

The balloon carries an infrasound microscope that is able to record sound waves in the atmosphere at frequencies lower than 20 hertz. The device is floating just 22 miles above the Earth when it picked up the strange sound.

It was Daniel Bowman, a student from the University of North Carolina, who designed and built the balloon equipment used in the study. The initial program managed by NASA and the Louisiana Space Consortium tested the flight of the equipment where they captured sounds from the atmosphere of Arizona and New Mexico. 
It was just one of the ten experiments flown atop of the High Altitude Student Platform that successfully picked up the sounds. 
The said program was able to launch more than 70 student experiments in search of a successful project since 2006.

As that one balloon fly over the height of 37,500 meters above Earth for 9 hours, which is just below the top of the stratosphere and higher than the flight height of airplanes, it got the record of the highest point an equipment carrying infrasound has ever reached.

But the record is not all that, the sound captured by the balloon is what researchers claimed as a signal that they never encountered before.

As Bowman has said, “It sounds kind of like ‘The X-Files’.” There is some possibility that the sound might have come from another alien life, but may also originate from wind farms, crashing ocean waves, atmospheric turbulence, gravity waves, and vibrations formed by the balloon cable.

Bowman reported, “I was surprised by the sheer complexity of the signal. I expected to see a few little stripes,” as he was pertaining to the visual representation of the sounds through spectrogram detailing. The frequency range below 20 hertz is not audible to human hearing frequency, so the team adjusted it faster during the analysis.

He added, “There haven’t been acoustic recordings in the stratosphere for 50 years. Surely, if we place instruments up there, we will find things we haven’t seen before.”

Infrasound carried at great distances from its source is usually formed by low-frequency wave-creating phenomenon, such as earthquakes, volcanic eruptions, thunderstorms and meteor showers. Scientists have long used infrasound detectors to monitor weather and geologic activity all over the planet. NASA also plans to use infrasound detectors on the much-awaited Mars mission.

What astronomers learned when Messenger space probe crashed into Mercury

May 8, 2015 / / 0 Comments



Excerpt from statecolumn.com


On April 30, NASA concluded an historic voyage known as the Mercury Surface, Space Environment, Geochemistry and Ranging mission. The mission came to an end when the spacecraft carrying analytical instruments, Messenger, crashed into the planet’s surface after consuming all of its fuel.
The mission was far from a waste, however, as NASA rarely expects to see the majority of the spacecraft they launch ever again. According to Discovery, The probe sent back a spectacular photo of the surface of Mercury, using the craft’s Narrow Angle Camera in tandem with the Mercury Dual Imaging System. The photo shows a mile-wide view of the nearby planet’s surface in 2.1 meters per pixel resolution.
Right after the probe delivered the photo to NASA’s Deep Space Network, which is a collection of global radio antennae that tracks data on the agency’s robotic missions around the solar system, the signal was lost in what scientists assume was the craft’s final contact with the closest planet to the sun.
The four-year mission came to an end when the craft could no longer maintain its orbit around the solar system’s innermost planet due to lack of fuel. Mercury is just 36 miles from the sun, compared to Earth, which is 93 million miles away from the center of the solar system. Mercury is a peculiar world, with both frigid and extremely hot temperatures. Messenger also revealed that Mercury has a magnetic field similar to that of Earth’s, created by the motion of metallic fluids within the planet’s core.
The main challenge the Messenger mission faced was getting the space probe into orbit around Mercury. Due to the planet’s proximity to the sun, it was extremely difficult for flight engineers to avoid its gravitational pull. In addition to the challenge of catching Mercury’s comparatively weak gravitational force, high temperatures also made things tricky. Messenger was equipped with a sunshield designed to protect the spaceship cool on the side that faced the sun. NASA engineers also attempted to chart a long, elliptical orbit around Mercury, giving Messenger time to cool off as it rounded the backside of the planet.
Messenger made over 4,000 orbits around Mercury between 2011 and 2015, many more than the originally planned one-year mission would allow.
With the close-up shots of Mercury’s surface provided by Messenger, NASA scientists were able to detect trace signals of magnetic activity in Mercury’s crust. Using clues from the number of impact craters on the surface, scientists figured that Mercury’s magnetized regions could be as old as 3.7 billion years. Astronomers count the craters on a planet in order to estimate its age – the logic being that younger surfaces should have fewer impact sites than older surfaces.
The data sent back by Messenger has caused astronomers to reconsider their understanding of Mercury’s magnetic history. They now date the beginning of magnetism on Mercury to about 700 million years after the planet was formed. They cannot say for sure, however, if the magnetic field has been consistently active over this timeframe.
According to Messenger guest investigator Catherine Johnson, geophysicist at the University of British Columbia in Vancouver, that it was possible the magnetic field has been active under constant conditions, though she suspects it might also oscillate over time, like Earth’s. Information for the time period between 4 billion years ago and present day is sparse, though Johnson added that additional research is in the pipeline.
Johnson was pleased, however, with the insight offered into Mercury’s formation provided by these new magnetic clues. Magnetism on a planetary scale typically indicates a liquid metal interior. Since Mercury is so tiny, scientists originally believed that its center would be solid, due to the rate of cooling. The presence of liquid in the planet’s center suggests other materials’ presence, which would lower the freezing point. This suggests that a totally solid core would be unlikely.
Mercury’s magnetic field offers valuable insight into the formation of the planet, the solar system, and even the universe. Magnetism on Mercury indicates that it has a liquid iron core, according to Messenger lead scientist Sean Solomon of Columbia University.
