Tyson describes the discovery of cosmic rays by Victor Hess through high-altitude balloon trips. Swiss Astronomer Fritz Zwicky, in studying supernovae, postulated that these cosmic rays originated from these events instead of electromagnetic radiation. Also tells how Vera Rubin observed that the rotation of stars at the edges of observable galaxies did not follow expected rotational behavior leading to consider the existence of dark matter. This further led to the discovery of dark energy to account for the increasing rate of expansion of the universe. Tyson then describes the interstellar travel of the two Voyager probes. Tyson tells the Carl Sagan's role in the Voyager program, including creating the Voyager Golden Record to encapsulate humanity and Earth's position in the universe. Tyson concludes the series by emphasizing Sagan's message on the human condition in the vastness of the cosmos, and to encourage viewers to continue to explore and discover what else the universe has to offer.

The BBC has made an extraordinary new documentary, presented by Sir David Attenborough, which will reveal the discovery of a fossilised skeleton that may be a vital ‘missing link’ in human evolution. The centrepiece of the programme is the unveiling of the first-ever complete skeleton of an extinct animal called an adapid

Set in the inner-city of Memphis, Undefeated chronicles the Manassas Tigers' 2009 football season, on and off-the-field, as they strive to win the first playoff game in the high school's 110-year history. A perennial whipping boy, in recent decades Manassas had gone so far as to sell their home games to the highest bidder, but that all changed in the spring of 2004 when Bill Courtney, a former high school football coach turned lumber salesman, volunteered to lend a hand.

In 2011, a Social Security lawyer named Eric C. Conn and a judge named David Daugherty were investigated for committing massive fraud over many years. Conn figured out that he would get paid a hefty retainer for every Social Security disability payment he managed to get approved, so he and Daugherty (who need quick cash to pay for his daughter’s upcoming narcotics trial – which presumably meant bribing an awful lot of people) came to an arrangement.
In the second episode, Investigators starts to collect evidence against Eric and Judge Daugherty. The whistle-blowers are pressured.

This is a film for all who hunger for a deeper meaning to existence, and a more unified way of living with one another, with all expressions of life. Just imagine a world that didn't rely on opposites (us/them, rich/poor, black/white, gay/straight, human/animal, etc.), but rather a world that perceived only wholeness. UNITY presents the notion of a world in which we are all equally valued, even though we are not the same: Human, Animal, Tree.

Dr Adam Rutherford shows how decoding the genome has led us to begin to understand the very process by which our DNA makes us different; how it makes each one of us on earth unique and influences who we are and the traits we have. He reveals how, as we try and understand the relationship between who we are and our genes, we stand at the beginning of the most exciting scientific journey of all time.
