    For years, astronomers have predicted a dramatic fate for our galaxy: a head-on collision with Andromeda, our nearest large galactic neighbor. This merger—expected in about 5 billion years—has become a staple of astronomy documentaries, textbooks and popular science writing.

    But in our new study published in Nature Astronomy, led by Till Sawala from the University of Helsinki, we find the Milky Way’s future might not be as certain previously assumed.

    By carefully accounting for uncertainties in existing measurements, and including the gravitational influence of other nearby galaxies, we found there is only about a 50% chance the Milky Way and Andromeda will ...

    Hubble takes Gigantic Image of the Triangulum Galaxy

    January 8, 2019, Categories  Astronomy/Space

    This gigantic image of the Triangulum Galaxy – also known as Messier 33 – is a composite of about 54 different pointings with Hubble’s Advanced Camera for Surveys. With a staggering size of 34 372 times 19 345 pixels, it is the second-largest image ever released by Hubble. It is only dwarfed by the image of the Andromeda Galaxy, released in 2016.

    The NASA/ESA Hubble Space Telescope has captured the most detailed image yet of a close neighbour of the Milky Way – the Triangulum Galaxy, a spiral galaxy located at a distance of only 3 million light-years...
