NASA's Mars Curiosity rover continues its exploration of the Red Planet. Now, it's officially reached a major landmark: Mount Sharp.
Elliptical galaxies have long been considered as being made up of old stars that move randomly within them. Now, though, scientists have taken a closer look at giant elliptical galaxies and have made some new findings when it comes to how they move.
Scientists have discovered giant holes in the electrically charged layer of the Venusian atmosphere, called the ionosphere, which paints a more complicated picture when it comes to Venus' magnetic environment.
It turns out that "hot Jupiters" have more of an effect on their host stars than scientists once though. Astronomers have found that these large, gaseous exoplanets can make their stars wobble when they pass through their own solar systems.
On Sept. 10, our sun ramped up its activity. The sunspot AR2158 erupted, producing an X1.6-class solar flare. Now, a double punch of CMEs may supercharge the Northern Lights.
Quasars are supermassive black holes located at the center of distant, massive galaxies. Now, scientists have solved a particular quasar mystery that has puzzled astronomers for over 20 years.
Scientists have officially identified and characterized what they're now calling the "Venus Zone," the area around a star in which a planet is likely to have similar unlivable conditions that can be found on the planet Venus.
A certain star cluster is not all that it seems, and may shed some light on the chemicals found in our universe, such as lithium.
NASA's Hubble Space Telescope has caught a glimpse of a companion star to a rare type of supernova.
A team of scientists have provided the first evidence of water ice clouds on an object outside our solar system.
Water is a huge component of our planet. It forms Earth's oceans and clouds, regulating the climate. Now, scientists have discovered the first evidence of water clouds on an object outside of our own solar system.
The third and final supermoon of the year will make its appearance tonight on Monday, Sept. 8. Barring any clouds, the full harvest moon is set to be a spectacular sight to see, so be sure to look toward the night skies.
