Eagle Nebula - Pillars Of Creation And Destruction
The Hidden Universe of the Spitzer Space Telescope (Episode 6): The Eagle Nebula - Pillars of creation and destruction.
This video series showcases some of the most exciting discoveries in infrared astronomy from NASA's Spitzer Space Telescope. Looking beyond the visible spectrum of light, Spitzer can see a whole new universe of dust and stars hidden from our Earth-bound eyes.
Theyre known as the Pillars of Creation, but according to recent Spitzer observations these ghostly apparitions have already met their own destruction!

Dan Meyer: Math class needs a makeover
Today's math curriculum is teaching students to expect -- and excel at -- paint-by-numbers classwork, robbing kids of a skill more important than solving problems: formulating them. At TEDxNYED, Dan Meyer shows classroom-tested math exercises that prompt students to stop and think.

What's In a Proton? Peter Steinberg
Physicist Peter Steinberg explains that fundamental particles like protons are themselves made up of still smaller particles called quarks. He discusses how new particles are produced when quarks are liberated from protons...a process that can be observed in Brookhaven Lab's Relativistic Heavy Ion Collider (RHIC).

Extrasolar Planets
Up until the 1990s, we only knew of the planets in our own solar system. Since then, we have discovered over 300 planets orbiting other stars (extrasolar planets, exoplanets). However, most of these planets were found when scientists observed the effect of the planet's gravity upon their host stars.
Astronomers could not show the world what we wanted most: a visible light picture of a planet around a star like the Sun. That situation changed in November 2008 with a discovery by the Hubble Space Telescope. Join us for the story that begins a new era in our knowledge of planetary systems.

Molecular Evolution: Genes And Proteins
Molecular evolution is the process of evolution at the scale of DNA, RNA, and proteins. Molecular evolution emerged as a scientific field in the 1960s as researchers from molecular biology, evolutionary biology and population genetics sought to understand recent discoveries on the structure and function of nucleic acids and protein. Some of the key topics that spurred development of the field have been the evolution of enzyme function, the use of nucleic acid divergence as a "molecular clock" to study species divergence, and the origin of non-functional or junk DNA.
