Halema'uma'u Crater March 29, 2008
Halema'uma'u crater has been erupting since March 19. On March 24 the fumes were joined by ash and molten particles. Halema'uma'u is located on the floor of Kilauea caldera--for years we children ould safely walk to the edge. Ash has been reported as far away as South Point (southernmost spot in the 50 states). Part of Chain of Craters Road is closed because of the hazard. The vent at Pu'u O'o has been erupting for years. Change is inevitable, even in the speed of light. Without Earth's internal heat our islands and continents would not have formed.
Cassini's close encounter with Enceladus was marred by a faulty sensor. Nevertheless, scientists have found traces of organic molecules in Enceladus' vapour plume. They have also found higher temperatures than were found before. The thermal view below of the South Pole shows heat emanating from the tiger stripe features. The interior likely has temperatures suitable for liquid water and life. For life to evolve so far from the Sun, internal heat would have to be maintained over billions of years. This is a good place to search for a Black Hole.
We have found organic molecules and possible internal heat on Titan, also considered a possible home of life. We grew up learning that life depends on a Sun. Inner heat of worlds may be more important to life than previously thought. Someday we may find that Black Holes and life are connected.
