In 1901 the star GK Persei gave off a powerful explosion that has not stopped growing and astonishing ever since. Now a team of Spanish and Estonian astronomers has reconstructed the journey of the emitted gas in 3D which, contrary to predictions, has hardly slowed down its speed of up to 1,000 km/s after all this time.

Thanks to the images captured from the Isaac Newton Telescope and the Nordic Optical Telescope in La Palma (Canary Islands, Spain), a European team of astronomers has constructed a three dimensional map of the remnant of a nova, or in other words, what was left of the star after its explosion. The results have just been published in the Astrophysical Journal.
