Astronomers have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us—and it may also be the closest [...]

Step outside as the stars come out, look southwest, and you’ll see an eye-catching pattern. For the next few days, bright orange Mars shines to the right of Saturn and the reddish supergiant star Antares. The three form a tall triangle that changes every night. Mars is moving leftward on its way toward passing between the other two. On August 23 and 24, the triangle shrinks down to a nearly [...]

The universe is 13.8 billion years old, while our planet formed just 4.5 billion years ago. Some scientists think this time gap means that life on other planets could be billions of years older than ours. However, new theoretical work suggests that present-day life on Earth is actually premature from a cosmic perspective. “If you ask, ‘When is life most likely to emerge?’ you might [...]

Light from a distant galaxy can be strongly bent by the gravitational influence of a foreground galaxy. That effect is called strong gravitational lensing. Normally a single galaxy is lensed at a time. The same foreground galaxy can—in theory—simultaneously lens multiple background galaxies. Although extremely rare, such a lens system offers a unique opportunity to probe the fundamental [...]

Two astronomers—with the help of Twitter—have uncovered the strongest evidence yet that an enormous X-shaped structure made of stars lies within the central bulge of the Milky Way Galaxy. Previous computer models, observations of other galaxies, and observations of our own galaxy have suggested that the X-shaped structure existed. But no one had observed it directly; and some astronomers [...]

The JunoCam camera aboard NASA’s Juno mission is operational and sending down data after the spacecraft’s July 4 arrival at Jupiter. Juno’s visible-light camera was turned on six days after Juno fired its main engine and placed itself into orbit around the largest planetary inhabitant of our solar system. The first high-resolution images of the gas giant Jupiter are still a few weeks [...]

NASAs Juno spacecraft will make its long anticipated arrival at Jupiter on July 4. Coming face-to-face with the gas giant, Juno will begin to unravel some of the greatest mysteries surrounding our solar system’s largest planet, including the origin of its massive magnetosphere. Magnetospheres are the result of a collision between a planet’s own magnetic field and the supersonic solar wind. [...]

When NASA’s New Horizons spacecraft buzzed by Pluto last year, it revealed tantalizing clues that the dwarf planet might have—or had at one time—a liquid ocean sloshing around under its icy crust. According to a new analysis led by Brown University, such an ocean likely still exists today. The study, which used a thermal evolution model for Pluto updated with data from New Horizons, [...]

If you cast your eyes toward the constellation Cygnus the Swan, you’ll be looking in the direction of the largest planet yet discovered around a double-star system. It’s too faint to see with the naked eye, but a team led by astronomers from NASA’s Goddard Space Flight Center and San Diego State University used the Kepler Space Telescope to identify the new planet, Kepler-1647b. Planets [...]

Before humans could take their first steps on the Moon, that mysterious and forbidding surface had to be reconnoitered by robots. In 1961, When President John Kennedy set a goal of landing astronauts on the lunar surface, little was known of that world, beyond what could be gleaned from observations by telescopes. Was the surface solid enough to support the 33,500-pound Apollo lunar lander? Or [...]
