NASA lost contact with the interstellar Voyager 1 spacecraft for nearly a week after a technical glitch shut off the probe's main transmitter. Using Voyager's weaker backup transmitter, engineers are assessing the problem from 15 billion miles away.

From nebulas and black holes to baby star nurseries and ancient collisions, the universe has never looked more beautiful thanks to NASA’s $10 billion-telescope.

The James Webb Space Telescope may have found dozens of elusive brown dwarfs — strange objects larger than planets but smaller than stars — beyond the Milky Way for the first time ever.

A powerful solar outburst hit Earth Thursday, triggering a "severe" geomagnetic storm. Auroras could be visible as far south as California and Alabama, NOAA predicts.

The more scientists study the Red Planet, the more they find unusual objects and patterns scattered across Mars' surface. Here are some of the most baffling.

On Oct. 2, a partial "ring of fire" solar eclipse was visible from the remote island of Rapa Nui, also known as Easter Island, where around 1,000 stone moai statues stand. You can see the whole celestial event play out in this incredible composite image.

The Oct. 2 partial solar eclipse, known as an annular or "ring of fire" eclipse, is about to begin over Easter Island and South America. Watch it for free right here.

Beyond our solar system, countless alien worlds of lava, ice, water and noxious gas swirl through the cosmos. Here are some of the strangest exoplanets that scientists have discovered so far.

On Sunday, Sept. 29, Earth captured a new "minimoon" called 2024 PT5. The bus-size asteroid is expected to orbit our planet for 57 days, but is too small to be visible to amateur skywatchers.

Long-sought evidence of alien life could lurk in Earth's oceans, or in 'weird' objects orbiting near our planet, Harvard astrophysicist Avi Loeb says. Here is his plan to find it.
