Black holes might be defects in spacetime

A team of theoretical physicists have discovered a strange structure in space-time that to an outside observer would look exactly like a black hole, but upon closer inspection would be anything but: they would be defects ...

NASA animation sizes up the universe's biggest black holes

A new NASA animation highlights the "super" in supermassive black holes. These monsters lurk in the centers of most big galaxies, including our own Milky Way, and contain between 100,000 and tens of billions of times more ...

NASA plans could threaten the future of New Horizons

The New Horizons mission currently flying through the Kuiper Belt could be facing an unexpected change of plans. NASA's Science Mission Directorate is soliciting input on turning the spacecraft into a heliospheric science ...

Giant galaxy seen in 3D

Though we live in a vast three-dimensional universe, celestial objects seen through a telescope look flat because everything is so far away. Now for the first time, astronomers have measured the three-dimensional shape of ...

Pluto team updates science from the solar system's edge

Nearly eight years after its historic Pluto flyby, NASA's New Horizons probe is getting ready for another round of observations made from the icy edge of the solar system—and this time, its field of view will range from ...

Models explain canyons on Pluto's large moon Charon

In 2015, when NASA's New Horizons spacecraft encountered the Pluto-Charon system, the Southwest Research Institute-led science team discovered interesting, geologically active objects instead of the inert icy orbs previously ...
