    The launch window for Artemis II opens on 6 February 2026. Humans will fly a test mission, swinging around the far side of the moon for the first time since Apollo 17 in 1972. There won’t be a landing, but just like Apollo 8 tested systems in the lunar vicinity before Apollo 11, Artemis II will test the modern systems under the same conditions the landing missions. There will be a crew of 4 including the first person of colour, the first woman and the first non American to fly beyond low Earth orbit. It really is a historic flight in so many ways.

    The Moon has a history longer than any of the features on Earth, but it isn’t as old as Earth. The Giant Impact hypothesis says that a Mars sized protoplanet collided with earth Billions of years ago and threw out enough of earth’s mantle to make the Moon. It’s an incredible story, and it might just have been the luckiest thing that ever happened for us. Without the Moon, life as we know it might never have existed.

    As the year winds down, let’s take a look at what the night sky has on offer in December 2025. The highlight has to be the Geminid Meteor Shower. Over a couple of nights this month, Earth crashes through the debris trail of asteroid 3200 Phaethon, producing a spectacular meteor shower. There’s a Supermoon in close proximity to the Pleiades star cluster, and we say goodbye to an interstellar traveller in 3I/ATLAS.

  • #84 Before exoplanets comes a protoplanetary disc, we’ve found heavy water in one of these. What does this mean for the history of planetary water?

    We’ve detected many exoplanets and exoplanetary stems, they orbit stars in other parts of the galaxy. These planets form the same way our planetary did, they coalesce from a protoplanetary disc of gas and dust. Scientists have recently found a useful kind of substance - heavy water in one of these protoplanetary discs, and it’s told us a lot about how water might end up in planetary systems.

    A billion light years away, a billion years ago, two black holes spiralled toward each other and collided, we detected its gravitational waves in January 2025. We’ve detected many of these before, but this one was different. It was such a strong, clear signal that we could test laws of physics that had been proposed many decades earlier. It even put Einstein to the test.

    In 1975, an incredible and unlikely partnership resulted in the docking of a NASA Apollo capsule and a Soviet Soyuz spacecraft in Earth orbit. The cold war opponents worked together to overcome not only engineering challenges, but the rivalry and suspicion of the cold war.

    This cooperation led to the Shuttle-Mir program in the 90s and the present day International space station. They all began with the spirit of cooperation from Apollo-Soyuz.

    Earth’s days had been getting longer since observations began. Every century, the length of the day would increase by about two milliseconds. Like… clockwork. In recent years, something strange has been happening, the days have started getting shorter as the rotation of the Earth has been speeding up. Even more strangely, we don’t really understand why.

    An Australian team of botanists and engineers are working on a project that might make or break the future of long term, long distance space occupation. They're growing plants. Not that unusual, but they're trying to grow them on the Moon. Plants produce oxygen and they are food, essential elements of living away from Earth.

    Let's check out the plan to experiment with germinating seeds in shoebox sized 'lunariums' on the Moon within the next 12 months.
