Scientists are getting a closer look at a supermassive black hole about 100 million light-years away. At the center of a galaxy known as KA 1858 is a black hole that now researchers have examined a bit more closely.
Astronomers have discovered eight new planets in the "Goldilocks" zone of their stars, orbiting at a distance where it's neither too hot nor too cold and where liquid water can exist on the planet's surface.
After working with temperatures as hot as the interior of the sun, researchers have managed to find out iron's role in inhibiting energy transmission from the sun to the near edge of its radiative band.
How to assemble Earth: Take elements, stir, and dash with water delivered by asteroids. Scientists are taking a closer look at how Earth-like planets are made in order to continue their hunt for exoplanets that have the likeliest chance at supporting life.
NASA has assembled the largest Hubble Space Telescope image ever. The new picture reveals a sweeping bird's-eye view of a portion of the Andromeda galaxy (M31) that's the sharpest large composite image ever taken of our galactic next-door neighbor.
A team of scientists have observed and recorded the largest-ever flare in X-rays from a supermassive black hole at the center of the Milky Way galaxy.
There may be a new way to tell the age of stars. As stars grow older, they slow down in terms of their spin. Now, astronomers are taking advantage of this fact to tackle stellar ages.
NASA's Hubble Space Telescope has captured a spectacular new image of the iconic view of the "Pillars of Creation," giant columns of cold gas bathed in the scorching ultraviolet light of young stars.
Scientists have found out that oceans on super-Earths, once established, can actually last for billions of years, which may explain a bit more about our own planet.
A new analysis of Martian chemical maps has revealed that there may be water bound to sulfates in the soil on Mars. Scientists have discovered a spatial association between the presence of sulfur and hydrogen found in the soil.
