The space news cycle was dominated for a while this month with the discovery of water vapour in the atmosphere of planet K2-18b. The planet is in the habitable zone of its star, but is somewhat larger than the Earth – what does that mean for its habitability?<\/p>\n

Meanwhile, radio astronomers have discovered the most massive neutron star found to date – close to the maximum theoretical limit.<\/p>\n

Closer to home, India’s first attempt at landing on the Moon has ended in disaster, with the Vikram lander crashing onto the surface in the final moments of its journey.<\/p>\n

And we’ve had a new interstellar visitor – a comet which appears to have come from another solar system. What could we learn from the interloper as it whizzes through our neighbourhood?<\/p>\n
