On a chilly yet beautifully clear evening last November, I sat on a video call with colleagues and happened to mention the live feed from the International Space Station - a real-time broadcast from onboard cameras as the station orbits earth.
Several people hadn't heard of it, and so I dug out the link and sent it over. We then turned to Nasa's spot the station smartphone app, which shows you the ageing satellite's orbital track and provides a countdown to when you can next see it. Again, I found the link and shared it on the chat.
I suddenly realised the station was going to pass directly overhead - in just a few minutes. Video beamed from the station as it advanced over the Atlantic, crossed the terminator (the line that separates day from night), and hurtled towards the southwestern tip of the UK, where I live.
Running outside, I took my phone and the live feed with me. And as I looked up at the bright, impossibly fast-moving smudge traversing the sky above, the feed showed the station's birdseye view - and perhaps the view of the astronauts aboard - looking down on me, too.
Just 25 years ago, this kind of experience would have been hard to imagine. Yet as our lives have become increasingly interwoven with technology, so too have our encounters with the world around us. And nowhere is this more true than when it comes to viewing the night sky .
Smartphone apps now help us to identify planets , catch views of satellite clusters (for better and worse ), and plan how to view supermoons . These experiences could be crucial in helping to reconnect people with the night sky and preserve a darkness that is increasingly under threat .
Simulations that allow people to view the Earth from afar, via apps or computer games, could even recreate a fascinating phenomenon reported by astronauts: the overview effect . Recently referred to by the Artemis II crew , the overview effect is described as a "a profound reaction to viewing the Earth from outside its atmosphere" . It represents a powerful form of awe and wonder and digital tools might help us unlock similar feelings from Earth too.
On May 11 2024, residents marvelled at the aurora borealis (northern lights) across parts of the UK including in southern England where they are rarely seen . The sightings made headlines across Europe, an excitement that was made possible by digital technology and heightened by digital shares and updates.
Public interest began with the National Oceanic and Atmospheric Administration's Deep Space Climate satellite picking up particularly strong solar winds. This triggered an alert to users of Lancaster University's Aurorawatch app . These stargazers started taking photos of the northern lights, which they promptly shared via social media .
The display happened close to midnight when most people in the UK were in bed - but still scrolling. And as real-time images of the aurora quickly circulated online, masses of people went outside to see it for themselves. But, as one witness reported, many people struggled to make out the display : "I could see nothing by eye, but it was there on the camera screen, and on my phone camera too." And so images of the sky were captured through ultra-sensitive smartphones.
From webcams in bird boxes to big-budget nature documentaries, these digital connections have come to define modern interactions with the natural world . They are now interwoven into everyday routines.
Ten million people watched the first episode of BBC's Planet Earth III in 2023 - the same number who visit the Peak District in a year . Nature-based "relaxation" videos have achieved viral status on YouTube, amassing hundreds of millions of views each. Spotify , Audible and Netflix have made nature content a core offering to their combined half a billion subscribers. Instagram is home to pictures of 346 million sunsets - and counting.
Online relationships
Being online can also have serious consequences for mental health, but when it comes to the natural world, digital connections could also provide exciting opportunities to bolster wellbeing. Growing research has shown that engaging with digital forms of nature can lead to improvements in emotion regulation, stress reduction and attention restoration - a pathway that is already being explored by apps hoping to boost wellbeing for people who spend large amounts of time online.
These digital encounters also have the potential to affect how people behave towards the environment .
Some academics are worried that these trends might be degrading our relationship with nature , but there is substantial nuance to be found here . The real value in these experiences may lie not in their ability to simulate natural worlds, but in their capacity to stimulate interest in nature .
Harnessing technology to "rewild" our digital lives could be especially relevant when it comes to an emerging generation of young people. Take for example, the perspectives of generation alpha, the first wave of which are entering their late teens, and who, after gen Z, represent the second cohort of digital natives - hyper-connected visual learners who have never known a world without smartphones, social media, instant access to information, and for some, artificial intelligence.
Perhaps, as some have suggested , modern and digital tools could even mean that young people's opportunities to connect with nature are unprecedented.
And so, as with some other innovations , these technological connections might enhance human experience, understanding and capability.
It could be time to recognise and embrace digital tools as part of the dynamic, evolving, and exciting way we interact with the natural world - approaches that might bring us closer to nature at a time when its future hangs in the balance .
