The comet 2I/Borisov, an interstellar visitor discovered gliding through our solar system back in August 2019, is beginning to break apart.

A team of astronomers has finally discovered definitive evidence of a mid-size black hole—the rarest and most elusive type of black hole.

For the first time, astronomers have captured a rare image of a supermassive black hole devouring matter and spewing out jets of heated plasma.

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.
