"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."

The alignment of seven planets in the night sky has captivated observers for centuries, inspiring awe and curiosity. This celestial event, commonly referred to as a planetary parade, is not just a visual spectacle but also a significant opportunity for scientific inquiry.

The Hubble Space Telescope completes a high-resolution portrait of our galaxy's gorgeous neighbor, which will help scientists better understand our Milky Way.

Rethinking the Underlying Trigger of Quasar Jets Building on the groundbreaking 2020 discovery of newborn jets in several quasars, the Hubble Space Telescope has revealed that one of the quasar host galaxies has an unexpected spiral shape.

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,

Throughout much of January and February, Venus, Mars, Jupiter, Saturn, Uranus and Neptune will be visible splayed out in a long arc across the heavens, with Venus, Mars, Jupiter and Saturn being ...

For the first time, astronomers have traced a fast radio burst (FRB) to the outskirts of an ancient, dead, elliptical galaxy—an unprecedented home for a phenomenon previously associated with much younger galaxies.

Six planets – Venus, Mars, Jupiter, Saturn, Uranus and Neptune – are currently ... However, if a large galaxy or cluster of galaxies passes between our line of sight with a much more distant ...

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.

"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 ...
