On September 14th, at 05:12 GMT (09:12 Moscow time) asteroid 2012 QG42 will fly at the distance of 0.019 AU – which is 2.84 million kilometers, or about 7.4 average distances from planet Earth to the Moon.

In the future, this asteroid will fly even closer to Earth.  On September 15, 2039 it will fly at the distance of 0.014 AU (5.6 distance to the Moon), and on February 15, 2013 at 23:25 MSK -at the distance of 26.9 thousand kilometers far from our planet.  This distance is shorter than the height of the geostationary satellites.

M.P.E.C. 2012-Q72, issued on 2012 Aug. 28, reports the discovery of the PHA asteroid 2012 QG42 (discovery magnitude 16.8) by Catalina Sky Survey on images taken on August 26.3 with a 0.68-m Schmidt + CCD.
2012 QG42 has an estimated size of 200 m – 500 m (H=20.4) and it will have a close approach with Earth at Read more…

Disintegrating Alien Planet Has Comet-Like Tail

September 5, 2012 Comments off

space.com

A potential alien planet that is so close to its parent star that it appears to be disintegrating from the scorching heat was recently found by a team of astronomers. The planetary candidate is only slightly larger than the planet Mercury, and researchers estimate that it is shedding so much material that it could completely disintegrate within 100 million years.

Astronomers at NASA and the Massachusetts Institute of Technology (MIT) detected the tiny planet, which is located roughly 1,500 light-years away, using data from the planet-hunting Kepler mission. As the possible planet evaporates, researchers theorize that it is followed by a trail of dust and debris, similar to the tail of a comet.

The dusty planet circles its host star once every 15 hours, which indicates that the star, named KIC 12557548, likely heats the planet to blistering temperatures of about 3,600 degrees Fahrenheit (1,982 degrees Celsius). The researchers hypothesize that under these conditions, the Read more…

Galactic Cosmic Ray Volleys: A Coming Global Disaster (Video)s

April 18, 2012 Comments off

starburstfound.org

This is a very interesting interview with Dr. Paul LaViolette regarding the superwave theory.  The interview is pretty lengthy, however, it provides much insight on how our position in the Milkyway Galaxy will affect us. 

Galactic core outbursts are the most energetic phenomenon taking place in the universe. During the early 60′s astronomers began to realize that the massive object that forms the core of a spiral or giant elliptical galaxy periodically becomes active spewing out a fierce barrage of cosmic rays with a total energy output equal to hundreds of thousands of supernova explosions(1, 2). The cosmic ray electron component of such an outburst is always accompanied by synchroton emission which consists of electromagnetic radiation ranging from Read more…

NASA Mystified By Enormous Energy Field

The revelations of our energetic Universe keep on coming from many sources, including NASA’s new satellites, and it’s quite remarkable.

The observable Universe is something mankind has read as a language since the beginning. The unobservable worlds have always been the realm of philosophers, religious expressions and the esoteric sciences.

Are they coming together via modern technology, as we approach the Singularity as some call it, as a manifestation of some sort of consciousness shift?

I think so.

The video below was sent to me by a dear friend at Philosophers Stone in confirmation of my last post on this subject. It so blew my mind I wanted to get it out there as a sequel of sorts and to reinforce the above.

Scientists In Awe

More information being collected by higher and higher technology is making some seriously profound discoveries.

NASA’s Fermi Gamma-Ray Telescope is finding hundreds of new objects at the very edge of the electromagnetic spectrum. Many of them have one thing in common: Astronomers have no idea what they are. Read more…

Nearby Star May Have 9 Planets

Artist’s impression of a planetary system around the star HD 10180. The large crescent is the third world in the system (HD 10180d), which is comparable to the planet Neptune in mass. The two inner planets appear as silhouettes in transit across the bright disc of the star. The outer planets in the system appear in the background sky. Credit: ESO/L. Calçada

HD 10180 is a star that’s nearly the Sun’s twin: it’s very close in mass, temperature, brightness, and even chemical content of our friendly neighborhood star. But in this case of stellar sibling rivalry, HD 10180 may have the upper hand: a new analysis of observations of the star indicate it may have nine planets!

In a new report accepted for publication in the journal Astronomy and Astrophysics, an astronomer re-analyzed data of the star taken with the High Accuracy Radial Velocity Planet Searcher (HARPS), an exquisitely high-precision camera mounted on a 3.6 meter telescope in Chile. HARPS has been observing HD 10180 for years; the star is a mere 130 light years away, making it bright and easy to study. The observations look to see if the star exhibits a periodic shift in its light: a Doppler shift as planets circle it, tugging it one way and another.

Six clear Doppler shift signals were found in the original analysis: six planets, five of which have masses ranging from 12 – 25 times that of the Earth (making them more like Neptune than our own comfortable planet), and a sixth that was bigger yet, 65 Read more…

Why is Venus rotating 6.5 minutes slower than it was just 16 years ago?

Scientists mapping Venus‘s surface with the European Space Agency’s Venus Express orbiter recently received a shock when features on the planet’s surface appeared to have moved up to 12.4 miles from where they were expected to be, reports National Geographic.
 
The measurements, if correct, would seem to indicate that Venus’ rotation has slowed by 6.5 minutes — a dramatic decrease on a planetary level — compared to when it was last measured just 16 years ago.
 
That last measurement was taken during NASA’s Magellan mission in the 1990s, when a single rotation of Venus was Read more…

GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. New observations from the NASA/ESA Hubble Space Telescope show that it is a water world enshrouded by a thick, steamy atmosphere.

Aguilar (Harvard-Smithsonian Center for Astrophysics))

An international team of astronomers led by Zachory Berta of the Harvard-Smithsonian Center for Astrophysics (CfA) made the observations of the planet GJ 1214b.

“GJ 1214b is like no planet we know of,” Berta said. “A huge fraction of its mass is made up of water.”

The ground-based MEarth Project, led by CfA’s David Charbonneau, discovered GJ 1214b in 2009. This super-Earth is about 2.7 times Earth’s diameter and weighs almost seven times as much. It orbits a red-dwarf star every 38 hours at a distance of 2 million kilometres, giving it an estimated temperature of 230 degrees Celsius.

In 2010, CfA scientist Jacob Bean and colleagues reported that they had measured the atmosphere of GJ 1214b, finding it likely that it was composed mainly of water. However, their observations could also be explained by Read more…

The strange haze of the Milky Way galaxy

New images from the European Space Agency’s Planck mission have revealed previously undiscovered islands of star formation, along with a mysterious haze of microwave emissions in our Milky Way galaxy.

“The images reveal two exciting aspects of the galaxy in which we live,” explained Planck scientist Krzysztof M. Gorski from NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and Warsaw University Observatory in Poland.

The strange haze of the Milky Way galaxy

”They show a haze around the center of the galaxy, and cold gas where we never saw it before.”

To be sure, the new images depict the entire sky, which is dominated by the murky band of our Milky Way galaxy.

One of them shows the unexplained haze of microwave light – which was previously hinted at in measurements by NASA’s Wilkinson Microwave Anisotropy Probe (WMAP).

“The haze [originates] from the region surrounding the center of our galaxy and looks like Read more…

Earth twin discovered 22 light-years away

February 3, 2012 Comments off

The Kepler mission initiated to find habitable Earth-like planets near our own has turned up another candidate for places we might visit in the future: GJ 667Cc. This planet has an orbital period of about 28 days regularly and has a mass that’s at least 4.5 larger than Earth. This planet is neither too hot nor too cold for liquid water to exist on the surface, and it sits aside two or three additional planets that may well be similar enough to also be Earth candidates. This newest discovery was made by astronomers from UC Santa Cruz Steven Vogt and Eugenio Rivera, lead by Guillem Anglada-Escudé and Paul Butler of the Carnegie Institution for Science.

 

The host star in this system is called GJ 667C and is an M-class dwarf star. Two more stars sit in the Read more…
