If you are a very early riser, or just planning on pulling an all-nighter, you could be lucky enough to catch a few meteors streaking across the sky just before the Sun comes up tomorrow morning.
A solar eclipse is happening later this week, and North Americans will have the best seats in the house for this stunning show.
NASA's three state-of-the-art Mars orbiters successfully dodged a comet and its dangerous debris just yesterday, after months of preparation for this rare fly-by event.
With a new detailed image of our closest star, NASA is revealing some the Sun's secrets with surprising information about its atmosphere.
Saturn has a good number of exciting moons circling it. Titan by far its most famous, boasting a mysterious sea of methane, and Enceladus is characterized by its baffling geysers of water vapor and ice particles. However, we may now be adding Mimas to that list of intriguing moons. A new study has revealed that the dull-looking moon is literally shaking with a mystery of its own.
Soil moisture is apparently NASA's secret weapon in a fight to better understand water availability and prevalence around the globe. That's why the space agency is prepping to launch its latest planet-monitoring spacecraft, designed specifically to measure this elusive factor.
The starry Milky Way Galaxy, seemingly innocent, is secretly stealing from nearby dwarf galaxies, making them devoid of star-forming gas, according to new research.
Uranus has always been a pretty lonely planet. The seventh planet from the Sun, this "ice giant" made primarily of ice particles, hydrogen, and helium is relatively unique, drifting around our solar system in an unusual elliptical orbit at a stunning 99 degrees axial tilt. Now, however, researchers are saying that the baby-blue planet has an unlikely twin 25,000 light-years away.
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft arrived at Mars and entered its orbit roughly three weeks ago, and it has now provided scientists their first look at the Red Planet's upper atmosphere.
Not every garden is immediately flush with countless flowers. Astronomers say the same is true for galaxies, in that some galaxies "bloom" much later in their long lives, pumping out stars at delayed rate. Now, a new study details why some galaxies appear to produce stars at a much slower rate compared to others.
The Moon was likely still volcanically active, even in its adolescence, researchers using NASA's Lunar Reconnaissance Orbiter (LRO) have found. New evidence indicates that unlike the formation of other natural satellites, the Moon did not cool immediately after its formation, but remained a roiling volcanic land for some time.
Our Milky Way galaxy harbors a lot of dark matter, but new measurements show that there is actually half as much of the mysterious substance as previously thought, according to a new study.
Here on Earth, people are gearing up for Halloween with pumpkin carvings, costume shopping and candy cravings, and it seems our Sun wants in on the fun, too. NASA has just released photos of the Sun and its active regions, looking eerily like a toothy grin on a jack-o-lantern's face.
Scientists are focusing on large, star-forming galaxies, whose radiation leaks are shedding light on the beginnings of the Universe as the first stars came into existence, new research says.
Most experts are too worried about the state of Earth's climate to be looking to the stars, but now a team of astronomers have used NASA's Hubble Telescope to help reveal what kind of temperatures and precipitation are felt on an exoplanet 260 light-years away.
