The massive asteroid that buzzed Earth on Monday didn't come alone. Scientists working with NASA's Deep Space Network antenna found that the asteroid was so large that it had its own small moon.
A new space telescope from NASA may be a breakthrough in terms of space exploration.
There may be a ring system that's actually larger and heavier than the famed rings of Saturn.
A swarm of tiny probes may have a mission--and that mission is the giant planet of Jupiter. Microprobes, which each have a different sensor, could be fired into the clouds of Jupiter and grab data as they fall before burning up in the gas giant planet's atmosphere.
Comet 67P/Churyumov-Gerasimenko continues to hurtle toward the sun, carefully watched by the Rosetta spacecraft. Now, scientists have noticed that this comet is practically hemorrhaging water as it continues its trip through space.
Do you remember Comet 67P Churyumov-Gersimenko? It's the comet that made headlines after a spacecraft landed on it. Now, the comet is "waking up."
Can you imagine creating planets in the lab? That's just what scientists are doing. They're conducted new laser-driven compression experiments to reproduce the conditions deep inside exotic super-Earths and giant planet cores.
Astronomers have spotted the first ever "changing look" quasar. This gleaming object is located in deep space and appears to have its own dimmer switch. The finding could offer astronomers a glimpse at the history of these brilliant objects.
NASA's Dawn spacecraft visited the protoplanet Vesta from 2011 to 2013. Now, scientists are getting a closer look at some images, and have discovered that Vesta may have had short-lived flows of water-mobilized material on its surface.
Our galaxy could be a massive wormhole, according to a new study. Based on the latest evidence and theories, the Milky Way could also potentially be "stable and navigable," which could prompt researchers to re-think dark matter.
Two of the last unexplored frontiers are the deep ocean and the depths of space. Now, scientists are combining these two fields with a new discovery.
NASA's Dawn spacecraft is closing in on the dwarf planet, Ceres. Now, the spacecraft has taken some new images of the tiny planet, revealing pictures that are about three times better than the ones taken in early December.
