Weekend Feature: ‘Lucy’ Discovered to Co-Exist With Tree-Climbing ‘Species’

A team of scientists has announced the discovery of a 3.4 million-year-old partial foot from the Woranso-Mille area of the Afar region of Ethiopia. The fossil foot did not belong to a member of "Lucy's" species, Australopithecus afarensis, the famous early human ancestor. The discovery of the Lucy hominin was significant because the skeleton shows evidence of small skull capacity akin to that of apes and of bipedal upright walk akin to that of humans, providing further evidence supporting the view that bipedalism preceded increase in brain size in human evolution. Research on this new specimen indicates that more than one species of early human ancestor existed between 3 and 4 million years ago with different methods of locomotion.

Weekend Feature: When Dark Energy ‘Turned On’ in the Universe

 

          Physics

Some six billion light years distant, almost halfway from now back to the big bang, the universe was undergoing an elemental change. Held back until then by the mutual gravitational attraction of all the matter it contained, the universe had been expanding ever more slowly. Then, as matter spread out and its density decreased, dark energy took over and expansion began to accelerate.

From the X-Files Dept: Saturday’s ‘Comment of the Day’

Gary Mckinnon hacked into NASA and found that they have an entire department dedicated to airbrushing artifacts out of NASA images. A smoking gun, in my opinion, for a huge cover up of other civilizations they don't care to tell us about. Also the goldilocks zone is a bit of a misnomer, as we continually find life in the most "inhospitable" places even on our own planet. It doesn't take one big leap of the imagination to realize the possibility of life in most regions of space; some of which is undoubtedly self aware and advanced.

NASA: “Goldilocks Planet Will Be Found Within Next Two Years”

Certainly you remember the story of Goldilocks and the tree bears told to you as a child by a knowing adult? What does a fairy tale have to do with Space exploration? As the numbers mount, it seems to be just a matter of time before finds what astronomers are really looking for:  an Earth-like planet orbiting its star in the "Goldilocks zone"—that is, at just the right distance for liquid water and life.

Mysteries of “The Redshift Desert” –Why Do Galaxies in the Early Universe Appear Old?

 

           Galaxies_no_txt_med

These highly developed galaxies, whose star-forming youth is in fact long gone, just shouldn't be there, but are." 

Dr. Karl Glazebrook (Johns Hopkins University).

Some of the faintest spectra in the universe raise a glaring question: Why do Galaxies in the early universe appear old? Until recently, astronomers have been nearly blind when looking back in time to survey an era when most stars in the Universe were expected to have formed. This critical cosmological blind-spot was removed in 2011 by a team using the Frederick C. Gillett Gemini North Telescope located on Mauna Kea, Hawaii, showing that many galaxies in the young Universe are not behaving as they would have expected some 8-11 billion years ago.
