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.
It turns out that Europa may just be able to support life and may be more like Earth than we thought. Scientists have found that the icy moon may have giant plates of ice that shuffle along its surface, much like plates of rocks do on Earth.
Scientists are taking a closer look at the birth of a planet. They've discovered what may be evidence of a planet forming around a star that's just 335 light-years from Earth.
Scientists may have come up with a novel model of dark mater, the mysterious substance that makes up about 80 percent of our universe. The findings could shed new light on the nature of dark matter and show the path for future research.
Scientists may have discovered a new marker to track the course of the solar cycle--brightpoints.
Our Milky Way galaxy isn't alone. Astronomers have found that it's part of a newly identified and huge supercluster of galaxies, which have been dubbed "Laniakea," which means "immense heaven" in Hawaiian.
