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 ...

For the first time, astronomers have obtained visual evidence that a star met its end by detonating twice. By studying the centuries-old remains of supernova SNR 0509-67.5 with the European Southern ...

Long theorized but never observed, the first known “planet with a death wish” is described by Ilin and her colleagues in a ...

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 ...

The NASA/ESA Cassini-Huygens mission explored Saturn and its moons from 2004 to 2017, providing the most detailed images and ...

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