The data will tell us more about how galaxies evolve and the rate at which supermassive black holes grow. The image also suggests there’s a supermassive black hole at the centre, and shows stars being born. James Webb has also caught a glimpse of Stephan’s Quintet, a group of five galaxies that are merging some 290 million light-years away in the constellation Pegasus. It was taken by the telescope’s Near-Infrared Camera (NIRCam). The picture is a composite “colour” image made from observations made at different wavelengths. Some of these may be among the most distant objects known, from the beginning of the universe. Images such as this will help us understand how the first stars and galaxies formed. But more distant galaxies in the image (the ones which appear stretched) are about 13 billion years old – and we already have more data on them than we have on any other ancient galaxy. The image shows the galaxy cluster as it appeared 4.6 billion years ago. The massive foreground galaxy groups magnify and distort the light of objects behind them, helping us to peer back in time at very faint objects. Unveiled by US president Joe Biden, the stunning image of SMACS 0723, a cluster of thousands of galaxies, was released on July 11. It’s a joy to finally have such high-quality data. It is very exciting to see the new images – I was not prepared for the level of crispness and fine detail that can be seen. The new “early release observations”, selected by an international committee of representatives from Nasa, Esa (European Space Agency), CSA (Canadian Space Agency), and the Space Telescope Science Institute, are part of a programme designed to highlight the wide range of science the telescope will carry out. Those of us who have been involved in the journey and will work on the data, can hardly wait. While this sometimes resulted in schedule slippages and cost increases, it has ultimately produced a perfect telescope.ĭuring July, the telescope moved from its checkout and testing phase to operation, as the amazing observatory it has long been planned to be. It also highlights the tremendous importance of the testing programme carried out on Earth to verify the procedures and which occasionally revealed problems that needed to be fixed before launch. This is not just a testament to the skill of the engineers, technicians and scientists in the project. But the programme was perfectly executed, a process that ran more smoothly and successfully than any one of us had dared hope, let alone expect. ![]() If any of these operations had failed, James Webb would have been an unusable disaster. On July 12, Nasa released the first scientific observations made by the suite of instruments carried on board the mission, marking what we eagerly anticipate will be the beginning of a new era in astronomy.Īfter the nail-biting launch on Christmas Day, a series of critical deployments followed to open up the telescope and its sun-shade. I'd have to try it out.After decades of development and many trials and frustrations along the way, the James Webb telescope has finally started to deliver what it came for. But that would only work if the slideshow always starts with the most recent image. So, even though I have configured the action to create a file called "Latest-NASA-APOD", it will create one called "Latest-NASA-APOD(1)" if there is already a "Latest-NASA-APOD" file there.Ī work-around may be to set the slideshow time interval to once a day, and periodically clear out my NASAAPOD folder. However, the "Upload file from URL" action in the IFTTT channel for Google Drive takes the (perhaps sensible) precaution of not over-writing a file if it already exists. ![]() This works fine in Windows - if there is only a single image in the slideshow folder, that's the image you get on your desktop. I don't want multiple images in my slideshow folder. I was hoping this recipe would give me a nice new spacey Windows desktop background every day when coupled with the ability in Windows to set the background to cycle through the contents of a specific folder. My recipe: If Image of the day by NASA, then upload file from URL to Google Drive
