UC Irvine astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would ...

In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small and in the Milky Way, while Curtis took a more radical position that they ...

New research from the SAGA Survey, comparing the Milky Way with 101 similar galaxies, unveils how our galaxy differs ...

Predictions are uncertain, but the solar system may be pushed farther from the galactic core or even ejected entirely from the new galaxy.

Image of the supermassive black hole Sagittarius A* (Sgr A*). from the Event Horizon Telescope (EHT) collaboration "has uncovered strong and organised magnetic fields spiralling from its edge," ...

A research team may have discovered a star with an exoplanet that is so fast that both will leave the Milky Way.

Sagittarius A* has been seen by human eyes with an "image produced by a global research team called the Event Horizon ...

Superclusters are large collections of galaxy clusters, groups, and individual galaxies that are typically not gravitationally bound to each other. For example, our Milky Way Galaxy is located on ...

Quipu, Hercules, Serpens–Corona Borealis and Sculptor–Pegasus are all larger than the fifth and final superstructure ...

NEW YORK — A neutrino detector submerged in the Mediterranean Sea has sniffed out the most energetic ghost particle yet, scientists reported Wednesday. The newly detected neutrino is around 30 times ...

The image of supermassive black hole Sagittarius A * was created using data from the Event Horizon Telescope Collaboration. At the same time several telescopes, including the Chandra X-ray Observatory ...
