A team of astronomers at Durham University in the UK have managed to calculate the exact diameter of the Milky Way galaxy—and it’s much bigger than anticipated.

My name is Ernesto Guido, and I’m an Italian amateur astronomer. My main interests lie in the astrometry and physical properties of comets and asteroids.

The supermassive black hole at the center of our galaxy, which is relatively inactive compared to others, has recently been ramping up its activity level.

NASA’s Transiting Exoplanet Survey Satellite (TESS) just discovered a new exoplanet with a star that follows an unusual orbiting path around the Milky Way—it orbits both above and below the galactic plane.

Ever since the Big Bang, the universe has been expanding at a calculable rate, though the exact rate is still in dispute. The universe's rate of expansion was famously discovered by Edwin Hubble back in 1929.

After analyzing six years worth of data from the Dark Energy Survey (DES), astronomers have discovered over 130 new minor planets near the edge of our solar system.

After months of painstaking assembly, NASA has just released the highest-resolution panorama of Mars yet.

Despite rather wild media speculation surrounding the cause of Betelgeuse’s recent inexplicable dimming, new research has finally provided a definitive answer.

NASA’s InSight, the most recent robot to inhabit Mars, is already sending back a lot of valuable data on the red planet, particularly on seismic and weather activity.

Exoplanets are notoriously difficult to discover and confirm—often hidden from regular telescope detection by the brightness of the stars they orbit.

Astronomers at the University of California, Riverside have discovered a peculiar ultramassive galaxy that existed for only a brief time in the early universe before becoming inactive. The ultramassive galaxy, known as XM

The European Southern Observatory (ESO) recently published an image of Jupiter in a way many are unlikely to ever witness—with a glowing halo emanating around it.
