Night sky puts on a meteor shower to celebrate Rosetta’s closest approach to the sun

...solar system. It was last at perihelion (its closest approach to the sun) in 1995. Each time the comet comes to the inner solar system, it sheds dust. Over time, this debris has built up, and is smeared out along the entire track of the orbit. Once a year, in August, the Earth’s orbit crosses that of comet Swift-Tuttle, and dust from the comet is captured. If you record...

...energy generated) created at times of surplus to non-renewable energy generators. So, many so-called 100% green electricity tariffs are a mix of fossil fuel, nuclear and renewables purchased on the wholesale market and then ‘labelled’ green by buying REGO certificates. Other ‘greenwashing’ electricity suppliers, including some who claim to supply 100% renewable...

...energy? Do they have a source of water? Do they have sites where water and rock can interact? Are they the right temperature – it can’t be so cold that nothing could survive. And finally, life takes a long time to get started. Has there been enough time for the moon to become habitable? [Photograph of the surface of Europa. The grey-blue icy surface is criss-crossed...

Reduce e-waste through donating old computer devices

...energy efficient. Moves to do this have started with ‘right to repair’ laws (although they do not cover computers or smartphones yet) and WEEE regulations (waste electrical and electronic equipment) but there are also things we can do now. [A pile of old discard laptop devices on a shop shelf] Reasons to donate Old computers can often have some life left in them. Here...

The Middle East conflict has swiftly exposed economic vulnerability in the region

...energy sector, and a vast AI campus in the UAE. It is these kinds of projects which led the World Bank and the World Economic Forum to publish glowing reports on the region recently. Both organisations agreed in late 2025 that oil wealth was being wisely invested for the future. The general view was that the GCC was a place of economic stability and diversity. A director...

As Cassini reaches the end, we should prepare the next mission

...solar system, or are they frozen ice and mud? Does Titan have a rocky core overlain directly by an icy mantle, or does it have an ocean below the surface? If so, is it made up of water? This all matters because what we have learnt about Titan from Cassini and Huygens has confirmed that it has an active chemistry, based on methane and ammonia. We know that these...

Primary science: supporting children’s learning

...solar system (big idea). Young children may play with parachutes and observe that they ‘slow down’ a falling object (small idea). Older children will learn about the gravitational and air resistance forces involved in this interaction (big idea). Children can develop ‘small ideas’ as steps towards the bigger ones. Braund and Leigh (2013) argued that in this way,...

...energy honey bees generate while flying and visiting flowers. Bumble and honey bees, along with butterflies, moths and hoverflies perform much of the pollination that is essential for us to grow food. Unfortunately, since World War II, these insects have seen dramatic global population declines – numbers of some British bumblebees are down as much as 70%. There are lots...
