Sedna will reach its closest approach to the Sun in 2076, providing a remarkable space-faring opportunity that won’t come ...

When astronomers first discovered exoplanets, they found massive ones orbiting large stars. The technology to detect smaller planets around low-mass, dim red dwarfs took time to develop. By the ...

Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare “double-detonation” supernova, where an initial helium blast on the star’s surface triggers a ...

The planet, which astronomers believe is orbiting a young red dwarf star approximately 34 light years away, has been dubbed ...

The dwarf planet Sedna will fly nearer the Sun in 2076. A nuclear rocket or a solar sail spacecraft could reach it within 7 ...

There could be life out there—way, way out there. Last Wednesday, NASA announced that its James Webb Space Telescope had discovered “compelling evidence” of a planet that is potentially habitable. The ...

The James Webb telescope has made another stunning discovery -- this time of a massive planet that could potentially sustain ...

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...

NASA's James Webb Space Telescope has been unwaveringly focused on our universe. With its unprecedented power to detect and ...

James Webb’s mid-infrared vision has likely captured a frigid, Saturn-mass planet shaping the dusty rings around the nearby ...

Since its debut in 2021, the James Webb Space Telescope has dazzled viewers with its infrared images of galaxies, nebulae, ...

Pictures of a distant supernova remnant show two concentric rings, providing clear evidence that exploding white dwarf stars ...
