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.

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.

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.

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 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.

A powerful solar outburst is likely to trigger a "severe" geomagnetic storm on Thursday, with auroras potentially visible as far south as California and Alabama, NOAA predicts.

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.

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.

Astronomers using the James Webb Space Telescope have spotted a feeding black hole in the early universe that seems to be eating 40 times faster than is theoretically possible.
