Galactic core outbursts are the most energetic phenomenon taking place in the universe. The active, quasar-like core of spiral galaxy PG 0052+251 (Figure 1-a), for example, is seen to radiate 7 times as much energy as comes from all of the galaxy's stars. Most of this is emitted in the form of high energy cosmic ray electrons accompanied by electromagnetic radiation ranging from radio wave frequencies on up to X ray and gamma ray frequencies.

A study of astronomical and geological data reveals that cosmic ray electrons and electromagnetic radiation from a similar outburst of our own Galactic core (Figure 1-b), impacted our Solar System near the end of the last ice age. This cosmic ray event spanned a period of several thousand years and climaxed around 14,200 years ago. Although far less intense than the PG 0052+251 quasar outburst, it was, nevertheless, able to substantially affect the Earth's climate and trigger a solar-terrestrial conflagration the initiated the worst animal extinction episode of the Tertiary period

The effects on the Sun and on the Earth's climate were not due to the Galactic cosmic rays themselves, but to the cosmic dust that these cosmic rays transported into the Solar System. Observations have shown that the Solar System is presently immersed in a dense cloud of cosmic dust, material that is normally kept at bay by the outward pressure of the solar wind. But, with the arrival of this Galactic cosmic ray volley, the solar wind was overpowered and large quantities of this material were pushed inward. The Sun was enveloped in a cocoon of dust that caused its spectrum to shift toward the infrared. In addition, the dust grains filling the Solar System scattered radiation back to the Earth, producing an "interplanetary hothouse effect" that substantially increased the influx of solar radiation to the Earth. Details of this scenario are described in Paul LaViolette's book Earth Under Fire,(1) in his Ph.D. dissertation,(2) as well as in a series of journal articles he has published.(3­8) LaViolette's research suggests that the Sun also became highly active as dust and gas falling onto its surface induced extreme flaring activity. Together with the radiation influx from the Sun's dust cocoon, this caused the Sun's corona and photosphere to inflate, much as is observed today in dust-choked stars called "T Tauri stars." These various solar effects caused atmospheric warming and inversion conditions that facilitated glacial growth which brought on ice age conditions. On occasions when the solar radiation influx to the Earth became particularly high, the ice age climate warmed, initiating episodes of rapid glacial melting and continental flooding. There is evidence that one particularly tragic solar flare event occurred around 12,750 years ago during a period when the Sun was particularly active. This involved the release of an immense coronal mass ejection which engulfed the Earth and induced a mass animal extinction.

Dr. LaViolette, who is currently president and chief researcher of the Starburst Foundation, was the first to demonstrate that cosmic rays from a galactic core explosion penetrate far outside a galaxy's nucleus to bombard solar systems like our own residing in the spiral arm disk. He coined the word "galactic superwave" to refer to such a cosmic barrage. He has shown that galactic superwaves recur at long intervals and arrive at Earth's doorstep without warning because they travel at near light speed. Galactic superwaves are a recent discovery. During the early 60's astronomers began to realize that the massive object that forms the core of our Galaxy (the Milky Way), periodically becomes active.(9) The cores of all spiral galaxies cycle through a similar phase. During its active period, our galactic core spews out a fierce quasar-like barrages of cosmic rays, with a total energy output equal to hundreds of thousands of supernova explosions.(10, 11) In some galaxies these active emissions have been observed to equal the energy from billions of supernova explosions. Until recently, astronomers believed these eruptions were very infrequent, occurring every 10 to 100 million years.(10) They also believed the interstellar magnetic fields, in the Galactic nucleus, would trap the emitted particles in spiral orbits causing them to reach the Earth very slowly.(12) For these reasons, many did not believe that Galactic core explosions posed any immediate threat to the Earth.

However, in 1983 Paul LaViolette presented evidence to the scientific community indicating that:(2 - 4)

1. Galactic core explosions actually occur about every 13,000 - 26,000 years for major outbursts and more frequently for lesser events.
2. The emitted cosmic rays escape from the core virtually unimpeded. As they travel radially outward through the Galaxy, they form a spherical shell that advances at a velocity approaching the speed of light.

Astronomical discoveries subsequently confirmed aspects of Dr. LaViolette's hypothesis. In 1985, astronomers discovered that Cygnus X-3, an energetic celestial source of cosmic rays, which is about the same distance from Earth as the Galactic Center (25,000 light years), is showering Earth with particles, traveling at close to the speed of light, moving in essentially straight paths.(13) Later, scientists found the Earth is impacted, at sporadic intervals, with cosmic rays emitted from the X-ray pulsar Hercules X-1 (about 12,000 light years distant).(14, 15) The intervening interstellar medium has so little effect on these particles, that their pulsation period of 1.2357 seconds, is constant to within 300 microseconds. These findings are reason to be gravely concerned about the effects of a Galactic core explosion because they imply that the cosmic rays generated can impact our planet, virtually without warning, preceded only by the wave-flash from the initial explosion.(1, 2, 6) Astronomical observations show the last major Galactic core explosion occurred as recently as 10,000 to 15,000 years ago.(16, 17) Data obtained from polar ice core samples show evidence of this cosmic ray event as well as other cosmic ray intensity peaks from earlier times (Figure 2).(1, 18)

Lower profile: Cosmic ray intensity at the Earth's surface calculated from variations in the concentration of beryllium-10 in the ice record adjusted for changes in ice accumulation rate. Upper profile: Global temperature. Climatic zones include: the present interglacial (1), last ice age (2, 3, & 4), previous semi-glaciated period (5a-d), last interglacial (5e), and previous glaciation (6). [An explanation of how this cosmic ray intensity profile was calculated from published beryllium-10 data is presented in the update to Dr. LaViolette's dissertation and in the appendix of a paper preprint available for download.]

Also Dr. LaViolette's prediction that there is a residual flow of interstellar dust currently entering the Solar System from the Galactic center direction was later verified by data collected from the Ulysses spacecraft and by AMOR radar measurements made in New Zealand.(8) For a listing of related theory predictions and their verification click here. Today, tomorrow, next week, next year. . . sometime in the coming decades. . . our planet could once again be hit by an intense volley of Galactic cosmic rays. It will come cloaked and hidden from us, until the very moment it strikes. We live on the edge of the Galaxy's volcano. Knowing neither the time, the magnitude, nor the severity of the next eruption or its impact on our environment, we stand unprepared to deal with this event, much less anticipate its arrival.
