Planets, Stars, Nebulae, Galaxies – Universe Size Comparison 2009 [HD]
***READ THIS BEFORE ASKING ANYTHING*** This is the ultimate size comparison video that you can find on the internet in HD. Starts with the tinyest dwarf planets of our solar system, then continues with large planets, dwarf stars, stars giant/supergiant/hypergiant stars, nebulae, globular clusters and galaxies. There is the famous VY Canis Majoris rated as the biggest star known, but very few know that that the incredible IC 1101 is the largest known object in the entire universe. Only galaxy clusters are bigger than it. Hope you enjoy this one. FAQ: -Sizes are not 100% accurate as there is no way to directly measure them. -Star sizes may change in the future, and new stars may eventually appear into this biggest stars list -Song: Celtic Panpipes – Ride on
The Most Distant Galaxies Ever Seen
In August, after the last repair mission on the Hubble Space Telescope, astronomers directed its newest camera towards the same area of sky where just five years ago, the first Hubble Ultra Deep field image was made and recorded a new one – this time in the near-infrared, a wavelength invisible to the human eye. Over the course of four days, the camera shutter was open for one hundred seventy three thousand seconds and astronomers collected photons that had left their galaxies over 13 billion years ago. Sensitive to slightly longer wavelengths than its predecessors, the newly installed camera known as Wide Field Camera three recorded objects that are likely the oldest galaxies ever identified, having formed only a few hundred million years after the Big Bang. Here are the results. [Music montage and interlude, couple minutes (music: Daemon portal)] Hubble’s new camera looks closer towards the Big Bang than any of the earlier cameras on the Hubble Space Telescope because it collects light from near-infrared wavelengths. The expansion of the universe stretches light from hot young stars in these very distant galaxies out of the ultraviolet and visible regions of the spectrum and into near-infrared wavelengths, making them redder and invisible to the human eye. As we build instruments sensitive to longer and longer wavelengths, we are able to peer farther into the cosmos and each wavelength brings us views closer to the edge of the universe. When we focus our instruments …
