You wouldn't think our planet experiences many close encounters from asteroids. Yet a new map shows exactly how often Earth's atmosphere is hit by small asteroids, called bolides.
Why didn't the universe collapse immediately after the Big Bang? That's a question that physicists have been struggling with for years. Now, they may just have their answer.
There may be a new method to detect dark matter. Physicists have taken a closer look at the current techniques and believe that they may just have a new way to detect elusive dark matter.
It turns out that the asteroid Vesta may have a history of large impacts. Scientists have completed the first geological and tectonic map of the asteroid, revealing a bit more about its past.
Scientists believe that warming and water flow on Mars was episodic and likely related to ancient volcanic eruptions.
Rosetta's Philae lander has now officially completed its primary science mission after nearly 57 hours on a comet. Now, it's earned a well-deserved rest. Philae is now hibernating after its power was rapidly depleted.
A new mission may just discover hundreds of new black holes throughout the universe.
Scientists have uncovered young, massive compact galaxies that are coming to an end of their intense bouts of star formation.
Scientists may have learned a bit more about the birth of our solar system. By examining magnetic fields trapped in grains within a primitive meteorite, researchers have pieced together how the early solar system evolved.
Astronomers have provided the first ever direct evidence that an intergalactic "wind" is stripping galaxies of star-forming gas as they fall into clusters of galaxies.
Could there be organic matter on Mars? The organic matter that was recently detected by NASA's rover Curiosity probably isn't due to contamination brought from Earth, as originally thought.
