![]() This article has been updated to correct the distances to the nearest star and galaxy. As the use of information from Earth-observing satellites. We won’t be able to answer every question, but we will do our best. Thanks to the satellite era we are better placed to understand and monitor our changing world. Hello, curious kids! Do you have a question you’d like an expert to answer? Ask an adult to send your question to Please tell us your name, age and the city where you live.Īnd since curiosity has no age limit – adults, let us know what you’re wondering, too. How to answer this question will need to be figured out by a future scientist. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.īut nobody knows for sure. In either case, you could never get to the end of the universe or space. If this were the case for the universe, it would mean it is not infinitely big – although it would still be bigger than you can imagine. If you start walking any direction, east for example, and just keep going, eventually you would come back to where you began. One way to think about this is to picture a globe, and imagine that you are a creature that can move only on the surface. Some scientists think it’s possible the universe might eventually wrap back around on itself – so if you could just keep going out, you would someday come back around to where you started, from the other direction. In that case, the universe would be infinite, with no end. Many think it’s likely you would just keep passing galaxies in every direction, forever. These are questions scientists don’t have definite answers to yet. If you could keep going out, as far as you wanted, would you just keep passing by galaxies forever? Are there an infinite number of galaxies in every direction? Or does the whole thing eventually end? And if it does end, what does it end with? A camera, moving at a constant speed towards Earth, will seem to move much faster the closer it gets to Earth. We counteract these issues with a feature called Logarithmic Altitude. Predictably, this raises some issues in the context of animation. The dots would keep moving farther apart, just like the galaxies are. Earth Studio requires us to deal with massive changes in scale. You can visualize this by imagining tiny dots on a deflated balloon and then thinking about blowing it up. Explore worldwide satellite imagery and 3D buildings and terrain for hundreds of cities. If you could watch for long enough, over millions of years, it would look like new space is gradually being added between all the galaxies. ![]() Using big telescopes, astronomers see millions of galaxies out there – and they just keep going, in every direction. ![]() ![]() Most of that space is almost completely empty, with only some stray molecules and tiny mysterious invisible particles scientists call “dark matter.” You would have to travel through millions of trillions more miles of space just to reach another galaxy. Michael Miller/Stocktrek Images via Getty Images The World in Real-Time global map utilizes Geographic Information Systems (GIS) to provide a live satellite view of select data from geostationary and polar-orbiting NOAA satellites and partner satellites of the Earth from space. Information from SEOSAT–Ingenio would have been used by different Spanish civil, institutional and government users, but also potentially by other European users in the framework of the European Union’s Copernicus programme and the Group on Earth Observations’ Global Earth Observation System of Systems.A galaxy among many other galaxies. Other partners included Airbus Defence and Space, being the prime industrial contractor of the satellite, and SENER & INDRA, responsible for the payload and ground segment. The mission was funded by Spain’s Centre for the Development of Industrial Technology (CDTI) of the Ministry of Science and Innovation, but developed by ESA in the context of the European Earth Observation Architecture. The so-called Planet Nine, a world 10 times more massive than Earth, is thought to be responsible for at least five strange features in the solar system including the oddly inclined orbits of a. While SEOSAT–Ingenio is a Spanish national mission, it is the result of an international collaborative effort. These could be combined to produce a true-colour image or to produce an image to highlight specific features such as vegetation growth. It was designed to capture images in the panchromatic band, meaning black and white, as well as in four multi-spectral bands: red, blue, green and near-infrared, at a resolution of 10 m. SEOSAT-Ingenio was based on a state-of-the-art dual camera that could image Earth’s land surface with a resolution of 2.5 m. ![]()
