It's the ultimate example of a "super star cluster." While most such clusters are about 10,000 times the sun's mass, Westerlund 1 is 50,000 to 100,000 times the solar mass. Some of its hundreds of ...

While good news for the Milky Way galaxy, the latest forecast may be moot for humanity. "We likely won't live to see the benefit," lead author Till Sawala of the University of Helsinki said in an ...

Astronomers now believe the Milky Way’s “inevitable” collision with a neighboring galaxy is much less likely than originally thought.

What does the Milky Way look like? Sometimes, the billions of stars comprising our home galaxy appear especially vibrant during “Milky Way season” as the band arcs across the night sky.

But the only way to get to a new prediction about the eventual fate of the Milky Way will be with even better data.” DOI: Nature Astronomy, 2025. 10.1038/s41550-025-02563-1 (About DOIs).

Milky Way’s chance of colliding with Andromeda galaxy is less than previously thought, astronomers report Science Jun 2, 2025 2:51 PM EDT ...

Milky Way's chance of colliding with Andromeda? New study puts odds at 50-50 For this new study, the scientists relied on updated galaxy measurements to factor in the gravitational pull on the ...

The researchers found that if the orbits of the Milky Way and Andromeda come close enough for the two galaxies to gravitationally influence each other, then a merger is an eventuality.

Now, this decade-long belief is being challenged by new research that suggests the Milky Way and Andromeda may not be on a collision course after all. The study, published today in Nature ...

Astronomers have discovered a strange new object in our Milky Way galaxy. The celestial object is emitting X-rays around the same time it's shooting out radio waves.
