Earth :: a global map of weather Educational video: The Sun for kids | Happy Learning Hello friends and welcome to a new Happy Learning video. Today we are going to learn about the most important star in the universe, today we’re going to study the Sun. The sun is a star, an enormous sphere of extremely hot gas which is continuously shining and spinning around. It seems much bigger and brighter than other stars but that is only because our planet is close to it, more so than to any other star. The sun is in the center of our system and that’s why we call it the solar system and all the planets in it revolve around the sun. The sun is composed of gas. Do you know how long it would take us to get to the sun? So now we have learnt a little more about the sun, our star and about light.
Your Age on Other Worlds Want to melt those years away? Travel to an outer planet! <div class="js-required"><hr> This Page requires a Javascript capable browser <hr></div> Fill in your birthdate below in the space indicated. The Days (And Years) Of Our Lives Looking at the numbers above, you'll immediately notice that you are different ages on the different planets. The earth is in motion. The top-like rotation of the earth on its axis is how we define the day. The revolution of the earth around the sun is how we define the year. We all learn in grade school that the planets move at differing rates around the sun. Why the huge differences in periods? Johannes Kepler Tycho Brahe Kepler briefly worked with the great Danish observational astronomer, Tycho Brahe. Here you see a planet in a very elliptical orbit. Kepler's third law is the one that interests us the most. Let's just solve for the period by taking the square root of both sides: The Gravity Of The Situation Isaac Newton ©2000 Ron Hipschman
Mission Alpha launch to docking highlights Highlights of the launch and first day in space of ESA astronaut Thomas Pesquet on the Alpha mission. On 24 April at 11:08 (CEST) the Crew Dragon spacecraft with ESA astronaut Thomas Pesquet, NASA astronauts Megan McArthur and Shane Kimbrough, and JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide docked with the International Space Station’s Node-2 Harmony module, marking the start of ESA’s six-month mission Alpha. The crew spent around 23 hours orbiting Earth and catching up with the International Space Station after their launch on 23 April at 10:49 BST (11:49 CEST, 05:49 local time). The launch to docking went smoothly in Crew Dragon Endeavour Thomas is the first ESA astronaut to fly in space in a vehicle other than the Russian Soyuz or the US Space Shuttle, and the first ESA astronaut to leave Earth from Florida, USA, in over a decade.

Pulsar Sounds (Jodrell Bank Observatory) A pulsar is a highly magnetised neutron star, with a radius of 10-15 km, having somewhat greater mass than the Sun which has a radius of approximately 1 million km. Radiation is beamed out along the magnetic poles and pulses of radiation are received as the beam crosses the Earth, in the same manner as the beam from a lighthouse causes flashes. Being enormous cosmic flywheels with a tick attached, they make some of the best clocks known to mankind. Pulsar recordings Some questions and answers What do I see in the movies? How are the sounds created? Why is the sampling rate not 44.1 kHz? Is there any need to correct for "dispersion"? I want to use these (or similar) sounds in an art project.

Espace : un amerrissage historique réussi pour des astronautes de l’ISS Publié le 02/05/2021 20:24 Article rédigé par La capsule Dragon a réussi son amerrissage de nuit et quatre astronautes sont de retour sur Terre après six mois dans la station spatiale internationale, dimanche 2 mai. Un exploit historique. Un amerrissage de nuit, un événement qui n’avait pas eu lieu depuis près d’un demi-siècle et les missions Apollo. Quelques heures plus tôt, dans la station spatiale internationale, l’équipage se disait au revoir. Partager :
Online Model of Solar System Espace : Thomas Pesquet a passé sept jours en orbite autour de la Terre Publié le 01/05/2021 12:54 Durée de la vidéo : 2 min. Article rédigé par L’astronaute Thomas Pesquet a retrouvé ses marques à bord de la Station spatiale internationale (ISS), où il réside depuis une semaine. "J'ai hâte de jouer au savant fou", a-t-il indiqué, vendredi 30 avril. Déjà une semaine que Thomas Pesquet, astronaute français, peut s'amuser à défier la gravité, ou plutôt le manque de gravité. Deux astronautes s'apprêtent à retrouver le plancher des vaches. Partager : SETI@home World Magnetic Model Calculator Use the tool below to compute values for the geomagnetic field and secular variation for a given set of coordinates and date. This calculator uses the World Magnetic Model as released in Dec 2019. Choose the geodetic latitude and longitude either by entering the coordinates into the form below (decimal degrees may be entered into the 'degrees' field, and degrees S or W should be entered with a negative sign), or by simply clicking the location on the map. The altitude and date may be set using the appropriate form fields. Clicking on the 'Show result on map' button will display the values for the chosen coordinates in a pop-up window. As this is based on a web service you can also obtain results in XML format using an HTTP GET request Please note that for Internet Explorer 10 and earlier there may be occasional erratic behaviour from the clickable map and the pop-up window.
The Large Hadron Collider The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. Inside the accelerator, two high-energy particle beams travel at close to the speed of light before they are made to collide. Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator. All the controls for the accelerator, its services and technical infrastructure are housed under one roof at the CERN Control Centre.
