JUPITER-CONJUNCTION-MOON
and THE RETURN OF THE ARCTIC AURORA:


Around the Arctic Circle, the night sky has been missing for months. "The midnight sun is a sore trial for amateur astronomers in the high North," says Fredrik Broms of Kval??ya, Norway.

"But now, after a long summer without stars (save one), darkness is falling again. Last night when I was watching the beautiful conjunction of Jupiter and the Moon, the first auroras of the season suddenly appeared!" He recorded the scene with a 1-second exposure on his Nikon digital camera:

JUNO PHOTOGRAPHS EARTH-MOON SYSTEM:

On August 26, 2011 NASA's Juno spacecraft, en route to Jupiter, has turned and photographed the Earth-Moon system from a dustance of million miles. "This is a remarkable sight people get to see all too rarely," says Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio.




"This view of our planet shows how Earth looks from the outside, illustrating a special perspective of our role and place in the universe. We see a humbling yet beautiful view of ourselves."

The image was taken by the spacecraft's camera, JunoCam, on Aug. 26 when the spacecraft was about 6 million miles (9.66 million kilometers) away. The image was taken as part of the mission team??s checkout of the Juno spacecraft. The team is conducting its initial detailed checks on the spacecraft's instruments and subsystems after its launch on Aug. 5.

Juno covered the distance from Earth to the moon (about 250,000 miles or 402,000 kilometers) in less than one day's time. It will take the spacecraft another five years and 1,740 million miles (2,800 million kilometers) to complete the journey to Jupiter. The spacecraft will orbit the planet's poles 33 times and use its eight science instruments to probe beneath the gas giant's obscuring cloud cover to learn more about its origins, structure, atmosphere and magnetosphere, and look for a potential solid planetary core.

The solar-powered Juno spacecraft lifted off from Cape Canaveral Air Force Station in Florida at 9:25 a.m. PDT (12:25 p.m. EDT) on Aug. 5 to begin its five-year journey to Jupiter.

ASTEROID FLYBY:


NASA radars are monitoring 2005 YU55, an asteroid the size of an aircraft carrier, as it heads for a Nov. 8th flyby of the Earth-Moon system. There is no danger to our planet. At closest approach on Tuesday at 3:28 pm PST, the 400m-wide space rock will be 324,600 kilometers away, about 85% the distance from Earth to the Moon.

Professional astronomers are eagerly anticipating the flyby as the asteroid will present an exceptionally strong radar target. Powerful transmitters at Goldstone and Arecibo will ping the space rock as it passes by, revealing the asteroid's shape and texture in crisp detail, and pinpointing its orbit for future flyby calculations. A movie from JPL explains:


Asteroids this big have passed by Earth at similar distances many times before, but this is the first time astronomers have known about the flyby in advance. For instance, a similar encounter occurred in 1976 when 2010 XC15 split the distance between Earth and the Moon. Researchers didn't discover that space rock until 24 years later! The Nov. 8, 2011, passage of 2005 YU55 thus represents a rare and valuable opportunity for asteroid research.

COMET LOVEJOY FROM ORBIT:

Veteran astronaut Dan Burbank has seen many amazing things. Once, he even flew through the aurora borealis. So when Burbank says "[Comet Lovejoy] is the most amazing thing I have ever seen in space," it really means something. Currently serving onboard the International Space Station, Burbank photographed the sungrazing comet on Dec. 21st, an experience he describes in this NASA video:

NEW YEAR'S FIREBALL:


The first bright fireball of the New Year streaked over the southwestern USA on Jan. 1st at 03:15 UT. It was visible from Arizona, Colorado and New Mexico. "I was able to see it out my window," reports amateur astronomer Thomas Ashcraft from his rural observatory outside of Santa Fe. "It was brilliant turquoise blue." Ashcraft operates a combination all-sky camera/forward-scatter meteor radar system, which captured the fireball's flight. Click on the image to play the movie--and don't forget to turn up the volume to hear the ghostly radar echo:



"This was an auspicious start to 2012," says Ashcraft. "Clear skies and Happy New Year!"

MARS AND THE SUPERNOVA:
March 18, 2012


"On March 18th, I photographed the planet Mars among the galaxies of Leo," reports amateur astronomer Oscar Mart?_n Mesonero of Salamanca, Spain. "The next morning, I learned that a supernova exploded in the galaxy M95. I quickly checked the photos and there it was!"

******If only the sky would put up yellow arrows pointing at things, cause i would have looked up at the sky and just thought that was another star and not an amazing supernova.

Nice topic!! and they say Astrology is hog wash!! I think not!




When you consider that we are made of gases and chemical reactions that exist in the universe at scales that we cannot even imagine, I can see how certain planets can affect a person. I mean, its been studied that the moon's phases seem to affect living things. There is something to be said for that. Like when people say, when there is a Full Moon, people and animals act out. Sure its possible since whatever made the moon also made the earth and in that cauldron, we humans evolved.

But even if you dont believe or trust in evolution and subscribe to creationism, you cant argue that many of the same scientific elements we find on Earth are also found all over the universe.

now according to the arrhenius equation chemical reactions move faster as temperatures increase. so atoms and molecules have to overcome an energy barrier(low temperatures) to react with each other. (but this does not apply to all reactions) ISM (interstellar mediums) clouds have to be active chemically to become stars in the frigid vastness of space. the ionization potential of the alkenes present in this cluster of chemically active ISM clouds, if at the appropriate temperature, will aid the chemical reaction of alkenes and oxygen (both in gas form) to give......



the chemical reaction (in space) that starts the occurence of a falling star 🙂

Now Astronomy:
While this chemical process continues to react (alkenes +oxygen), the earth moves around the sun at record speeds. rocks (in the atomosphere) are caught up in the chemical reaction. heat builds up due to the earth surrounding the sun, eventually this makes the rocks start to glow and burn. as it continues to spin and spin the hotter it gets. and it forms this meteor aka shooting star.....

far away...


close up...


looks like a meat ball ...LOL anyway when they crash on earth they create

this..



i thought it was interesting how astro chemistry explained the beginning chemical processes of meteorites. so cool i didnt learn that in astronomy.

James Cameron reaches deepest spot on Earth
Associated Press — 2 hrs 27 mins ago


The director of "Titanic," ''Avatar" and other films used a specially designed submarine to dive nearly seven miles, completing his journey a little before 8 a.m. Monday local time, according to Stephanie Montgomery of the National Geographic Society.

He plans to spend about six hours exploring and filming the Mariana Trench, about 200 miles southwest of the Pacific island of Guam.

"All systems OK," were Cameron's first words upon reaching the bottom, according to a statement. His arrival at a depth of 35,756 feet came early Sunday evening on the U.S. East Coast, after a descent that took more than two hours.



******The scale of the trench is hard to grasp — it's 120 times larger than the Grand Canyon and more than a mile deeper than Mount Everest is tall.******



Cameron made the dive aboard his 12-ton, lime-green sub called "Deepsea Challenger." He planned to collect samples for biologists and geologists to study.

"It's really the first time that human eyes have had an opportunity to gaze upon what is a very alien landscape," said Terry Garcia, the National Geographic Society's executive VP for mission programs, via phone from Pitlochry, Scotland.

The first and only time anyone dove to these depths was in 1960. Swiss engineer Jacques Piccard and U.S. Navy Capt. Don Walsh took nearly five hours to reach the bottom and stayed just 20 minutes. They had little to report on what they saw, however, because their submarine kicked up so much sand from the ocean floor.

"He is going to be seeing something that none of us have ever seen before. He is going to be opening new worlds to scientists," Garcia said.

Now, from my previous post I stated that stars are formed from a chemical reaction of alkenes and oxygen. well that was new information to me. because for years physicist and chemist claimed that sulfur was involved in the formation of stars. and there was proof found of this with super nova. They claim that sulfur particles are expelled from falling stars/meteorites when they land on earth. evidence of sulfur can be found in the stardust around and in the crater. This sulfur would have to be H2S, Hydrogen Sulfide, very toxic and flammable. Its basically in stink bombs, my college mates and I used to set off a stink bomb when we wanted to leave lab early. horrible smelling stuff...anyway on back on topic....

When I wrote that other post, I realized there was no mention of sulfur. When I read about the chemical processes and test of super nova i wonder how sulfur even got in the mix. I know that its everywhere. Its in our soil, chemistry, sometimes in water and food, but how did it get into the chemical composition of a meteor?

Well with isotopic analysis scientist like Max Planck (German Physicist, founder of plancks contant E=hv) and some other researcher discovered .1 to 1 micrometers of silicone carbide, which made more since than H2S. these samples where derived from super nova.

According to Plancks:
"The stardust grains we found are extremely rare. They represent only about the 100 millionth part of the entire meteorite material. That we have found them is much of a coincidence - especially since we were actually looking for silicon carbide stardust with isotopically light silicon," says Peter Hoppe. "The signature of isotopically heavy silicon and light sulfur can plausibly only be explained if silicon sulfide molecules were formed in the innermost zones in the ejecta of a supernova." Afterwards, the sulfide molecules have been enclosed in the condensing silicon carbide crystals. These crystals then reached the solar nebula around 4.6 billion years ago and were subsequently incorporated into the forming planetary bodies. They finally reach the Earth by meteorites which are fragments of asteroids. Carbon monoxide and silicon monoxide were already detected in the ejecta of supernova explosions in infrared spectra. Although models predicted the formation of sulfur molecules, it has not yet been possible to prove this. The measurements on silicon carbide stardust now provide support to the predictions that silicon sulfide molecules arise a few months"

the sulfide molecules got into the stardust mixture AFTER the meteor landed. But Carbon monoxide (alkenes +oxides) and Silicon monoxide (vapors form Silicon Dioxide (glass)) were present prior to the meteor landing. So of course when a rock is exposed to high temps of heat you get glass and vapors.
So when you see this:


you will find pieces like these:




inside the crater and around the perimeter.

The pressure is immense and the heat is substantial but.. that is not enough. these rock are only quartzite. they have silicon dioxide, meaning they are only glass, when manufactured they can become the glass on the face of your watch or something like that. but scientist have found microdiamonds or nanodiamonds from ancient meteorites, but that is due to them being exposed on earth for a long period of time. they do not have any value( because they are so small), you can crush them with 2 fingers. that is why scientist use these diamonds to determine the age of the meteorite. if they are left there to bare the elements of nature i would say in a billion years, it would be worth more. but with just one substantial thermal impact they cant become diamonds.

and you are absolutely right, they did not become diamonds because they do not have enough carbon also, quartzite is formulated with a chemical process using an alkene gas (2C). diamonds are not, they are created by carbon (solid)in the earth. also diamonds have a isotope of 13C. diamonds are exposed to high thermal temperatures repeatedly,(platetonics, magma, etc) most diamonds found today are over a billion years old..about the age of the earth. that is how long it takes for an authentic diamond to form. scientist work very hard to develop a faster way to develop diamonds. but diamonds are like fossil fuels, once they are all used up, there arent any more for another billion years.

A 'super Earth' near a 'hot Neptune' in space
By Ned Potter | ABC News — 10 hrs ago



.............So much for that..................


Since the 1990s, astrophysicists report they have identified at lest 600 stars with planets circling them and found that solar systems like ours are a rarity.

Take Kepler 36, reported Friday in the journal Science. It's a solar system about 1,200 light-years from our own, with two very different planets right on top of each other. One is a rocky "super Earth," about 1.5 times as large as our world. The other is a gaseous "hot Neptune," about 3.7 times as large.

"They are the closest to each other of any planetary system we've found," said Eric Agol of the University of Washington, one of the researchers. He and his colleagues spotted the planets using NASA's Kepler probe, which has been planet-hunting since 2009.

Both worlds are probably infernos, so close to their host star that they zip around it in 14 and 16 Earth-days, respectively. That means they pass very close to each other - less than five times as far apart as our moon is from us. If you've ever been struck by moonrise on a summer night, imagine a world about 12 times as large.

David Aguilar, a space artist at the Harvard-Smithsonian Center for Astrophysics, has done us the favor of imagining the scene himself. The result is the conception above.

Which is good, because the two planets are so close to their sun (11-12 million miles, compared to our 93 million) that you wouldn't want to go there yourself.

NASA's rover Curiosity lands on Mars

By Elizabeth Landau, CNN
Mon August 6, 2012



The SUV-sized Curiosity made its dramatic arrival on Martian terrain in a spectacle popularly known as the "seven minutes of terror."

This jaw-dropping landing process, involving a sky crane and the world's largest supersonic parachute, allowed the spacecraft carrying Curiosity to target the landing area that scientists had meticulously chosen.

The mission control in NASA's Jet Propulsion Laboratory in California burst into cheers as the rover touched down. Team members hugged and high-fived one another as Curiosity beamed back the first pictures from the planet, some shed tears.

"Rationally I know it was supposed to work all along, but emotionally it always seemed completely crazy," said James Wray, assistant professor at Georgia Institute of Technology, who is affiliated with the Curiosity science team of Curiosity. "So to see all those steps being ticked off and actually working, it's a huge relief."

The spacecraft had been traveling away from Earth since November 26 on a journey of approximately 352 million miles (567 million kilometers), according to NASA.

The vehicle, which will be controlled from the Jet Propulsion Laboratory, has a full suite of sophisticated tools for exploring Mars. They include 17 cameras, a laser that can survey the composition of rocks from a distance and instruments that can analyze samples from soil or rocks.

The aim of its work is "to assess whether Mars ever had an environment able to support small life forms," NASA says.

If all goes according to plan, Curiosity's first stop will be Gale Crater, which may have once contained a lake. After at least a year, the rover will arrive at Mount Sharp, in the center of the crater.
