For years, astronomers believed the Milky Way and Andromeda were on a direct collision course in about 4.5 billion years. But new research using data from our Gaia mission and Hubble Space Telescope suggests the story isn’t so simple.
After running 100 000 simulations with the most precise data available, scientists now say there’s only a 50% chance the two galaxies will collide in the next 10 billion years.
The Large Magellanic Cloud, one of our satellite galaxies, could be tugging the Milky Way just enough to steer it away from Andromeda. Instead of crashing, the two galaxies might simply orbit each other in a slow cosmic dance.
So the fate of the Milky Way remains uncertain. And with the Sun expected to make Earth uninhabitable in about a billion years, a galaxy collision is low on our list of concerns.

Did you know the Large Magellanic Cloud, one of our galaxy’s closest neighbors, survived a dramatic collision with the Milky Way’s gaseous halo? Despite losing most of its gas, the Large Magellanic Cloud is still forming new stars—a testament to its resilience! Thanks to Hubble Space Telescope, astronomers measured the Large Magellanic Cloud’s halo for the first time, revealing incredible insights about galaxy interactions.

Thousands of never-before-seen young stars are spotted in a stellar nursery called 30 Doradus, captured by the @NASA/ESA/@Canadian Space Agency James Webb Space Telescope. Nicknamed the Tarantula Nebula for the appearance of its dusty filaments in previous telescope images, the nebula has long been a favourite for astronomers studying star formation. In addition to young stars, Webb reveals distant background galaxies, as well as the detailed structure and composition of the nebula’s gas and dust.

Each year, the NASA/ESA Hubble Space Telescope dedicates a small portion of its precious observing time to taking a special anniversary image, showcasing particularly beautiful and meaningful objects. These images continue to challenge scientists with exciting new surprises and to enthral the public with ever more evocative observations.
To celebrate Hubble’s 30th anniversary, let’s look back at the beauty and science behind each of the anniversary images unveiled as of 2005. In this video, we will also feature the very special 2020 Hubble Space Telescope 30th anniversary image.

On 24 April 1990 the NASA/ESA Hubble Space Telescope was sent into orbit aboard the space shuttle Discovery, the first space telescope of its kind. It offered a new view of the Universe and has, for 30 years, reached and surpassed all expectations, beaming back data and images that have changed scientists’ understanding of the Universe and the public’s perception of it. Hubble’s discoveries have revolutionised nearly all areas of current astronomical research, from planetary science to cosmology, and its pictures are unmistakably out of this world.
This video revisits some of Hubble’s biggest science discoveries throughout its three decades of operation to celebrate the telescope’s 30th anniversary.

This month marks the 30th anniversary of the international Hubble Space Telescope.
Launched on 24 April 1990, and deployed from the Space Shuttle Discovery cargo bay a day later (25 April 1990), the telescope has given us a new perspective on the Universe.
The joint NASA/ESA mission has shown us distant galaxies and spectacular nebulae. It has revealed supermassive black holes and planets in distant solar systems; and has proved that the Universe is not only expanding, the expansion is accelerating.
Hubble’s mission has also been eventful. When it was first launched, a defect in the mirror meant it sent back blurry images. Since then, five servicing missions have enabled the telescope to be improved and upgraded. Today, it is still going strong.
