Science@ESA (Episode 4): Following The Redshift (Part 1) – The Earliest Stars and Galaxies In The Universe. From HST (Hubble Space Telescope) to JWST (James Webb Space Telescope). In this fourth episode of the Science@ESA vodcast series Rebecca Barnes will identify some of the key discoveries achieved with the famous Hubble Space Telescope, look at the concept of redshift, and meet a new telescope that will be used to uncover the early Universe. — • www.youtube.com • www.youtube.com — ‘Redshift’ is a key concept for astronomers. The term can be understood literally – the wavelength of the light is stretched, so the light is seen as ‘shifted’ towards the red part of the spectrum. Something similar happens to sound waves when a source of sound moves relative to an observer. This effect is called the ‘Doppler effect’ after Christian Andreas Doppler, an Austrian mathematician who discovered that the frequency of sound waves changes if the source of sound and the observer are moving relative to each other. If the two are approaching, then the frequency heard by the observer is higher; if they move away from each other, the frequency heard is lower. There are many everyday examples of the Doppler effect – the changing pitch of police and ambulance sirens, or train whistles and racing car engines as they pass by. In every case, there is an audible change in pitch as the source approaches and then passes an observer. Everyone has heard the increased pitch of an approaching …

Watch this smallest UFO or tiny plane or odd shaped flying object flying through Hydrolines and hitting them sometimes. Video taken in NewMarket, Ontario, Canada. Sometimes it is so steady and sometimes fly zigjzg. This plane is visible to naked eye only if one looks keenly with a more focus. … TINY UFO CRAFT ZIGJAG FLYING SPACE AVIATION SCIENCE TECHNOLOGY HYDRO LINES ONTARIO CANADA SAUCER DISC PLANE
