Astronomers used a 3D global computer model to compare the climates of exoplanets in different stellar and orbital configurations. They found that a planet orbiting a white dwarf star would offer a ...

Researchers at the University of Warwick believe they have found certain stars which may look pink, purple and even green if ...

Red dwarfs make up the vast majority of stars in the galaxy. Such ubiquity means they host the majority of rocky exoplanets we've found so far—which in turn makes them interesting for astrobiological ...

Add Yahoo as a preferred source to see more of our stories on Google. Red dwarfs dominate the neighborhood and often host rocky worlds in temperate orbits. Yet their environments may hinder complex ...

Could white dwarf stars host habitable exoplanets that might support life as we know it? This is what a recent study published in The Astrophysical Journal hopes to address as an international team of ...

About 4,000 degrees Celsius (7,200 °F) is cool for a star. An ordinary star at that temperature should look orange. But ...

Planets appear to be common around stars in our home galaxy, the Milky Way. Astronomers have found planets not just for stars like our sun, but also for smaller, cooler red dwarfs and other types of ...

An 87-minute binary reveals a small star steadily taking material from a brown dwarf, offering an alternative to rapid engulfment.

Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions. Hubble's ultraviolet observations finally revealed the long-hidden stellar remnants, ...

This artist's conception illustrates the brown dwarf named 2MASSJ22282889-431026. NASA's Hubble and Spitzer space telescopes observed the object to learn more about its turbulent atmosphere. Brown ...

Astronomers studying extreme planetary systems have identified worlds so massive that they rival the smallest stars in size. These giant planets blur the line between planetary and stellar ...
