Researchers may be a step closer to identifying dark matter after studying unusual cases of gravitational lensing caused by "dark matter halos" surrounding distant galaxies.
The hefty space rock, known as 2006 HV5, is around 1,000 feet wide and will hurtle past our planet at around 39,000 mph.
The 14-foot great hammerhead washed ashore on a beach in Alabama. Researchers have since dissected the expectant mother but are unsure exactly what killed her.
The sisters were separated at birth due to medical complications, and they remained apart for more than two years after one was rejected by the mother.
The rover has finally lost a pesky rock that had become lodged in its front left wheel "like a pebble in its shoe." The stone had accompanied the rover for more than half its time on the Red Planet.
NASA has converted years of satellite data on Earth's magnetosphere into eerie sound clips that can be used by citizen scientists to help make new discoveries.
Shortly after Mercury reached its closest point to the sun, its massive, comet-like tail became unusually visible in the night sky and was captured in a stunning new photo.

Astronomers accurately predicted that the icy volcanic comet 29P would erupt after noticing changes in its brightness leading up to its latest explosion.
The potential new mineral was discovered in a chunk of "fossilized lightning," or fulgurite, that was left behind when a tree in Florida was struck by lightning.
Researchers were able to replicate how solar flares form by creating banana-sized loops of plasma in a lab. The results show that the mini flares are an excellent proxy for studying the real things.
Gold miners unearthed a mangled lump of mummified flesh, which upon further inspection turned out to be a balled-up Arctic ground squirrel.
The never-before-seen fish was spotted 5 miles below the ocean's surface in the Izu-Ogasawara Trench near Japan.
An enormous red halo of light flashed in the night sky above Italy before disappearing within milliseconds. It was likely caused by an electromagnetic pulse from a nearby thunderstorm.
Lolita, also known as Tokitae, is returning to the waters of the Pacific Northwest more than half a century after her capture there.
Researchers have mapped out at least 85,000 volcanoes on Venus' surface, and recent findings suggest that some of them are likely active.
A river of hazy red light stretched across the night sky over Denmark after the most powerful solar storm to hit Earth for six years slammed into our planet. The rare phenomenon is not an aurora.
Researchers unearthed the "shark hook" at a newly discovered village buried under a known archaeological site. Experts say it could be one of the first of its kind made in the area.
Researchers have serendipitously discovered that a key step in photosynthesis can occur much earlier in the process than previously believed.
