Hinging our happiness on animals known to have a significantly shorter lifespan than our own was, in hindsight, a bad idea. Saying goodbye to a pet is an incredibly painful time in a person’s life, but what if there were a way we could help our pets live longer, better lives? That’s exactly what Celine Halioua has been exploring as CEO and founder …

Solar activity goes through cycles. The main one is about 11 years long and its maximum is marked by powerful eruptions of electromagnetic radiation known as solar flares, as well as releases of plasma known as coronal mass ejections. The most powerful known flare happened in 1859 and led to telegraph stations catching fire across the US, and North…

There are many methods that allow us to look back into Earth’s past and study its climate, including the collection of ice cores. Extracting ancient ice from deep inside some of the most remote glaciers can reveal how our planet has changed over millions of years. But it’s not just about the past: what is ancient ice telling us about the future? Ho…

The Sun shapes what goes on in space around our planet. Plasma from our star is continuously thrown at Earth in the form of solar winds or coronal mass ejections, changing the shape of the magnetic field, and affecting the atmosphere and anything in it, like the satellites that we depend on. These changes are part of what we call space weather. Hos…

Space junk is a problem and it’s only set to get worse. In 2018, there were over 2,000 satellites in orbit. Now, thanks to mega-constellations like Starlink, there are 9,000 satellites, and by the end of the decade, this number is expected to reach 60,000. A crowded space environment runs the risk of Kessler Syndrome, where there is so much polluti…
