"At first, I thought I completely messed up during our research," Olivia Achenbach of the United States Naval Academy told reporters on Monday (Jan. 13) at the 245th meeting of the American Astronomical Society in Maryland. "Because it's such a large supermassive black hole at the center, we'd predicted we'd see an elliptical galaxy."

New research suggests that a massive, unidentified object might have passed through our Solar System billions of years ago, leaving a lasting imprint on the orbits of our planets. This intriguing hypothesis,

In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby stellar island to our Milky Way—the magnificent Andromeda galaxy (Messier 31).

Our galaxy, while not small, isn't nearly as big as Andromeda. We harbor some 100 to 400 billion stars. One day, however, the two galaxies may collide, forming a giant, egg-shaped elliptical galaxy.

The magnificent Andromeda galaxy (Messier 31), stands out as the most important nearby stellar island to our Milky Way, and can be seen with the naked eye on a clear autumn night as “a faint cigar-shaped object roughly the apparent angular diameter of our Moon” according to NASA.

"Andromeda looks like a transitional type of galaxy that's between a star-forming spiral and a sort of elliptical galaxy dominated by aging red stars," said Weisz. "We can tell it's got this big ...

The Samsung Galaxy S25 Ultra could be the best Android phone of 2025, and you won’t have to wait until late in the year for it, with this handset set to land later today (January 22).
