Airport radar around the world leak electromagnetic energy into space, signaling our location on Earth up to 200 light-years away. This is Narita International Airport in Japan. Image via Nickika
Astronomers say Earth could be located in a billion-light-year-wide void, illustrated here by the green dot. If so, matter would flow away from us due to stronger gravity from the
The New Horizons spacecraft, which has left the solar system, beamed back images that have led to the first test of deep-space navigation. That is, New Horizons imaged 2 stars,
This spectacular spiral galaxy is Messier 83, also known as the Southern Pinwheel. New research on this galaxy may help explain how galaxies are able to sustain star formation over
Mario Rana in Virginia captured this frame of Saturn at 5:07:56 a.m. EDT (9:07:56 UTC) on July 5, 2025. See that bright flash on the limb indicated by the blue
This is a Hubble image of the spiral galaxy M100. This spiral galaxy in Coma Berenices is about 56 million light-years away. It has a supermassive black hole at its
View larger. | Artist’s illustration of the Mars Reconnaissance Orbiter (MRO). The Mars orbiter is using a new rolling maneuver – turning it essentially upside down – to help it

Recent studies have hinted that at least some Type Ia supernovae could be best explained by a double explosion. And now astronomers have captured a new image proving this hunch
