25 ethereal astronomy photos that literally light up the skies

Not all of us have a billionaire brother who can let us hitch a ride into space, so we rely on talented photographers to give us a glimpse into the beyond.

London's Royal Museums Greenwich has unveiled the finalists for the Astronomy Photographer of the Year 2021. The astrophotography competition, which has been running for 13 years, received over 4,500 entries taken from 75 countries.

Below, you'll find a collection of the incredible finalists, with the full shortlist available on the RMG website. The winners will be announced Sept. 16 before an exhibition of the images opens at London's National Maritime Museum from Sept. 18.

From magical views of the Milky Way over French lavender fields to a truly hardcore looking sunspot, this year's finalists literally light up the skies and space around our planet. There are nine categories including skyscapes, aurorae, people and space, our sun, our moon, stars and nebulae, galaxies, and planets, comets, and asteroids.

If you're keen for more otherworldly looks into the stars, here are last year's winners.
