Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Jupiter Bombarded

Posted by feww on July 22, 2009

Jupiter, the solar system’s largest planet, was bombarded by a Small Solar System Body (SSSB)

Jupiter, the “biggest guy at the door,” as if functioning as a major part of the solar system’s “defense labyrinth,” protecting the inner planets, took a massive pounding from an  asteroid or comet, which left a dark bruise the size of Pacific Ocean [and growing.]

The event is the first of its kind in 15 years, planetary scientists at the Jet Propulsion Laboratory said.

About 15 years ago, a fragments of the Shoemaker-Levy comet, made up mostly of hydrogen and helium, plunged into the large gaseous  planet.The astronomical object that struck the planet went unobserved. However, the impact “was most likely the result of a single asteroid, not a chain of fragments” striking Jupiter, as was the case with Shoemaker-Levy, Franck Marchis, a University of California-Berkeley astronomer, was reported as saying.

Jupiter Portrait – This true color mosaic of Jupiter was constructed from images taken by the narrow angle camera onboard NASA’s Cassini spacecraft on December 29, 2000, during its closest approach to the giant planet at a distance of approximately 10 million kilometers (6.2 million miles).  It is the most detailed global color portrait of Jupiter ever produced; the smallest visible features are approximately 60 kilometers (37 miles) across. The mosaic is composed of 27 images: nine images were required to cover the entire planet in a tic-tac-toe pattern, and each of those locations was imaged in red, green, and blue to provide true color. Although Cassini’s camera can see more colors than humans can, Jupiter’s colors in this new view look very close to the way the human eye would see them.

Visible Planet Orbits. This diagram shows the relative size of the orbits of the seven planets visible to the naked eye. All the orbits are nearly circular (but slightly elliptical) and nearly in the same plane as Earth’s orbit (called the ecliptic).  The diagram is from a view out of the ecliptic plane and away from the perpendicular axis that goes through the Sun.  Image Credit: Lunar and Planetary Institute via NASA Solar System Exploration.

The inner planets [aka, terrestrial planets, telluric planets, rocky planets,] Mercury, Venus, Earth, and Mars, their sizes to scale.

We Have an Eclipse!

Posted by feww on July 22, 2009

The Longest Eclipse of 21st Century

Totality or total  solar eclipse occurs when the moon, passing between Earth and sun, totally hides the latter. [See also occultation and Syzygy]

The solar eclipse is seen in Yinchuan, capital of north-west China’s Ningxia Hui Autonomous Region, at 08:33 local time today. Photo: AP. Image may be subject to copyright.

The eclipse  was visible only in Asia reaching totality in India about 06:20 local time, moving on to north and east to Nepal, Burma, Bangladesh, Bhutan and China.

To see a longer eclipse you’ll have to wait for about 123 years!
