Organic Ejecta –Clues to Violent Events in the History of the Universe

 

Pinwheel_Spitzer

 

Exploding stars, random impacts involving comets and meteorites, and even near misses between two bodies can create regions of great heat and high pressure. Researchers from Imperial College London have now developed a method for analysing the pressure experienced by tiny samples of organic material that may have been ejected from dying stars before making a long journey through the cosmos. The researchers have investigated a type of aromatic hydrocarbon called dimethylnaphthalene, which should enable them to identify violent events in the history of the universe.

The team also believe that their new technique could be applied on Mars, potentially using the existing technology on-board roving laboratories such as the one on the Mars Science Laboratory Mission to glean information about sources of organic matter on the red planet. Recognising the pressures recorded in the aromatic hydrocarbons can help to reveal whether it came from processes generated from ancient living organisms.Samples of dimethylnaphthalene are found in meteorites. Previously, scientists have only had the ability to investigate how they have been affected by heat. The Imperial researchers say their method for detecting periods when dimethylnaphthalenes have experienced high pressure will now allow for a much more comprehensive analysis of organic materials.

Milky Way Galaxy May Have Formed Inside-Out, Study

Jan 21, 2014 by Sci-News.com

Our Milky Way Galaxy formed by expanding out from the center, suggests analysis of first data from the Gaia-ESO survey – the ground-based extension to the Gaia space mission, launched by the European Space Agency at the end of 2013.

The astronomers involved with the Gaia-ESO project took detailed observations of stars with a wide range of ages and locations in the Galactic disc to accurately determine their ‘metallicity’: the amount of chemical elements in a star other than hydrogen and helium, the two elements most stars are made from.

Immediately after the Big Bang, the Universe consisted almost entirely of hydrogen and helium, with levels of “contaminant metals” growing over time. Consequently, older stars have fewer elements in their make-up – so have lower metallicity.

“The different chemical elements of which stars are made are created at different rates – some in massive stars which live fast and die young, and others in sun-like stars with more sedate multi-billion-year lifetimes,” said Prof Gerry Gilmore from the University of Cambridge, who is a co-author of the paper submitted to the journal Astronomy and Astrophysics (arXiv.org version).

Massive stars, which have short lives and die as ‘core-collapse supernovae’, produce huge amounts of magnesium during their explosive death throes. This catastrophic event can form a neutron star or a black hole, and even trigger the formation of new stars.

Scientists discovered three new planets orbiting stars in a cluster about 2,500 light years from Earth. Remarkably, among them they found an exoplanet orbiting a star which is almost identical to our own Sun in all respects.

The fascinating find was made by astronomers from the Max Planck Institute for Extraterrestrial Physics in Germany. They have been monitoring 88 promising-looking stars in a formation called Messier 67 for the past six years. Messier 67 is a cluster of about 500 stars in the constellation of Cancer.

The discovery is so exciting because it is the first time astronomers have found an exoplanet orbiting a star which is almost identical to our sun, in a cluster of stars. The star, similar to the sun in mass, temperature and chemical composition, was named YBP1194.

The second planet that was discovered is also orbiting a star similar to the Sun. The third one is circling a more massive and evolved red giant star.

SPACE WEATHER BALLOON UPDATE:

by Dr. Tony Phillips.

The payload of a space weather balloon launched Jan. 8th by the students of Earth to Sky Calculus has been recovered from its landing site in Death Valley National Park. The purpose of the flight was to study a solar radiation storm in progress at the time of the launch. Analyzing the data may take a few days. Meanwhile, here is the view from the stratosphere:

These pictures were taken by a pair of Hero3+ cameras looking out of the payload capsule. The upper frame shows the Sierra Nevada mountain range, unusually brown for this time of year as California endures a historic drought. The lower frame captures the balloon popping at an altitude of approximately 100,000 feet. Click on each frame for a closer look. The landscape shot was made using the Hero3+’s new “superview mode”–a favorite of snowboarders and now, for the first time, balloonists!

In addition to cameras, the payload contained an x-ray/gamma-ray dosimeter, a GPS altimeter, and a cryogenic thermometer. Together these instruments can form a complete thermal and radiation profile of the atmosphere throughout the flight. The students plan to pay special attention to data collected at aviation altitudes to learn how much radiation air travelers absorb during periods of high solar activity.

While everybody else were ringing in 2014 early Wednesday morning, scientists caught sight of what appeared to be a very small asteroid — between 2 and 3 meters in size — on a potential impact trajectory with Earth.

The observation was made at the Catalina Sky Survey near Tucson, Arizona. The space rock, designated 2014 AA, may have been the first asteroid discovery of the New Year. If the space object was an asteroid, scientists, using the scant observational data that was available to them, suggest that it probably entered Earth’s atmosphere sometime between 2 p.m. EST, Wednesday, Jan. 1 and 9 a.m. EST Thursday, Jan. 2.

Three independent projections of the space object’s possible orbit were made by Bill Gray, of the Minor Planet Center in Cambridge, Massachusetts, and Steve Chesley from NASA’s Near Earth Object Program at the Jet Propulsion Laboratory in Pasadena, California. The two scientists agree that 2014 AA probably pushed its way into Earth’s atmosphere.

Using data produced by weak signals from three infrasound detections, the crisscrossing of the white lines in this image indicates a possible impact point of asteroid 2014 AA (Peter Brown/University of Western Ontario)

Because of the uncertainty of the object’s orbit, 2014 AA could have fallen anywhere along an arc that extends from Central America to East Africa.

The scientists think that the object may have impacted Earth at 9 PM EST on Jan. 1, just off the coast of West Africa.

NASA said that since another asteroid, 2008 TC3, which was also between 2 to 3 meters in size, completely broke up in October 2008 as it passed over northern Sudan, it’s doubtful that asteroid 2014 AA would have made it through its rough atmospheric entry intact.

Asteroid 2008 TC3, according to NASA, was the only other example of an incoming celestial object that was discovered just prior to hitting Earth.

The scientists are continuing their research into the fate of 2014 AA. They will be analyzing data generated by a few weak signals collected from infrasound — low frequency — monitoring stations located along the predicted impact arc to see if they could be connected to the atmospheric entry of 2014 AA

All Sky Fireball Network

Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by NASA’s Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth’s atmosphere and many other characteristics. Daily results are presented here on Spaceweather.com.

On Jan. 4, 2014, the network reported 35 fireballs.
(19 sporadics, 14 Quadrantids, 1 lambda Bootid, 1 December Leonis Minorid)

In this diagram of the inner solar system, all of the fireball orbits intersect at a single point–Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue). [Larger image] [movies]

On Jan. 3, 2014, the network reported 27 fireballs.

Jan. 16 May Be Last Best Chance to Search for Comet ISON’s Remains

Is there any hope of detecting what’s left of Comet ISON after the sun proved too much for its delicate constitution? German amateur astronomer Uwe Pilz suggest there remains a possibility that a photographic search might turn up a vestige of the comet when Earth crosses its orbital plane on January 16, 2014.

Comet ISON is located high in the northern sky near the familiar "W" or "M" or Cassiopeia during the time of orbital crossing. Stellarium

On and around that date, we’ll be staring straight across the sheet of debris left in the comet’s path. Whatever bits of dust and grit it left behind will be “visually compressed” and perhaps detectable in time exposure photos using wide-field telescopes. To understand why ISON would appear brighter, consider the bright band of the Milky Way. It stands apart from the helter-skelter scatter of stars for the same reason; when we look in its direction, we peer into the galaxy’s flattened disk where the stars are most concentrated. They stack up to create a brighter band slicing across the sky. Similarly, dust shed by Comet ISON will be “stacked up” from Earth’s perspective on the 16th.

Geminid meteor shower set to peak, but moon might curtail viewing

Dec. 9, 2013 at 6:26 PM ET

Geminid

SkyandTelescope.com
This chart shows the radiant point for the Geminid meteor shower.

This week marks the peak of what is usually considered the most satisfying of all annual meteor displays: the Geminid meteor shower.

As was the case with last month’s Leonid meteor shower, however, prospective skywatchers should be aware that once again, observers will face a major obstacle in their attempt to see this year’s Geminid performance, namely, the moon.

Unfortunately, as luck would have it, the moon will turn full on Dec. 17, and as such, will seriously hamper viewing the peak of the Geminids, predicted to occur in the overnight hours of this Friday to Saturday. Bright moonlight will flood the sky through much of that night, playing havoc with any serious attempts to observe the usually spectacular meteor shower. [See amazing photos of the 2012 Geminid meteor shower]

The Geminids are already around, having been active only in a very weak and scattered form since about Dec. 7. Geminid activity is expected to be on an upswing in the nights to come, leading up to their peak on Friday night.

Historically, this shower has a reputation for being rich both in slow, bright, meteors as well as rather faint meteors, with relatively few of medium brightness. Many Geminid meteor shower streaks appear yellowish in hue. Every once in a while, a Geminid fireball will blaze forth, bright enough to be quite spectacular and more than capable of attracting attention even in bright moonlight.

“If you have not yet seen a mighty Geminid fireball arcing gracefully across an expanse of sky, then you have not seen a meteor,” astronomers David Levy and Stephen Edberg wrote in their book, “Observe Meteors,” published by the Astronomical League.

Dark sky opportunities
The best times to look for streaking Geminids this year will be during the predawn hours several mornings before the night of full moon when the constellation Gemini will be standing high in the northwest sky.

l times in this chart are a.m. and are local standard times. “MS” is the time of moonset. “Dawn” is the time when morning (astronomical) twilight begins. “Win” is the available window of dark sky composed of the number of minutes between the time of moonset and the start of twilight.

In fact, three “windows” of dark skies will be available between moonset and the first light of dawn on the mornings of Dec. 13, 14 and 15. Generally speaking, there will be about two hours of completely dark skies available on the morning of Dec. 13. This window shrinks to only about an hour on the 14th, and to less than 10 minutes by the morning of the 15th.

Hercolubus. WHAT?????

BPEarthWatch BPEarthWatch

 

Published on Dec 3, 2013

UPDATE. Solar and Quake Links http://www.bpearthwatch.com
http://es.wikipedia.org/wiki/Herc%C3%…
Hercobulus would be found in a solar system called Tilo course, that would be closer to the Earth and in the twentieth century prophesied that produce catastrophe of apocalyptic end times , the 11 of August of 1999 .
The writer cited Rabolú supposedly astronomical data considered relevant to consider the alleged threat of Tilo. 4 5 6 These data would be his size, 6 times larger than Jupiter in July and that the action of its huge gravitational field would be the producer of a major disaster. Affirms that Hercobulus is about 500 AU (astronomical units: the average distance between Earth and the Sun, about 150 million kilometers) from Earth and when approaching to 4 AU from Earth, generate a catastrophe. Also mentions that in 1999 and the planet would be observed as a major star at dawn. 8
According Rabolú in his book, Hercobulus would have passed through the Earth some 13,000 years ago, destroying the ancient civilization of Atlantis .
Hercolubus or Red Planet has aroused curiosity in many followers of the philosophies pertaining to the current New Age , however lacks the slightest scientific basis . Rabolú follower of the doctrine Gnostic touted by the late Samael Aun Weor (Víctor Gómez Rodríguez), argues that the goal of the approach is the assumption Hercobulus purification earth aura.
