The ALPHA collaboration at CERN in Geneva, Switzerland, has reported the first-ever measurement of an antimatter atom’s optical spectrum. This achievement opens up a completely new era in high-precision antimatter research. It is the result of over 20 years of work by the CERN antimatter community. “Using a laser to observe a transition in antihydrogen and comparing it to hydrogen to see [...]

Boron has been identified for the first time on the surface of Mars, indicating the potential for long-term habitable groundwater in the ancient past. “No prior mission to Mars has found boron,” said Patrick Gasda, a postdoctoral researcher at Los Alamos National Laboratory. “If the boron that we found in calcium sulfate mineral veins on Mars is similar to what we see on Earth, it would [...]

NASA’s Saturn-orbiting Cassini spacecraft has made its first close dive past the outer edges of Saturn’s rings since beginning its penultimate mission phase on Nov. 30. Cassini crossed through the plane of Saturn’s rings on Dec. 4 at a distance of approximately 57,000 miles above Saturn’s cloud tops. This is the approximate location of a faint, dusty ring produced by the planet’s [...]

Frozen beneath a region of cracked and pitted plains on Mars lies as much water as what’s in Lake Superior, largest of the Great Lakes, researchers using NASA’s Mars Reconnaissance Orbiter have determined. Scientists examined part of Mars’ Utopia Planitia region, in the mid-northern latitudes, with the orbiter’s ground-penetrating Shallow Radar (SHARAD) instrument. Analyses of data [...]

Two geo-scientists at Arizona State University have made a discovery among hot springs in Chile that may spur scientists to revisit a location on Mars explored several years ago by NASA’s Spirit rover. The discovery involves fingerlike structures that form in the hot spring deposits by processes that combine biological and non-biological activity. The Chilean hot springs are at a place [...]

Beneath Pluto’s “heart” lies a cold, slushy ocean of water ice, according to data from NASA’s New Horizons mission. In a paper published in the journal Nature , the New Horizons team reports that the dwarf planet’s most prominent surface feature—a heart-shaped region named Tombaugh Regio—may harbor a bulging, viscous, liquid ocean just below its surface. The existence of a [...]

Laser-zapping of a globular, golf-ball-size object on Mars by NASA’s Curiosity rover confirms that it is an iron-nickel meteorite fallen from the Red Planet's sky. Iron-nickel meteorites are a common class of space rocks found on Earth, and previous examples have been seen on Mars, but this one, called “Egg Rock,” is the first on Mars examined with a laser-firing spectrometer. To do so, [...]

Astronomers using observations from NASA’s Kepler and Swift missions have discovered a batch of rapidly spinning stars that produce X-rays at more than 100 times the peak levels ever seen from the Sun. The stars, which spin so fast they’ve been squashed into pumpkin-like shapes, are thought to be the result of close binary systems where two Sun-like stars merge. “These 18 stars rotate in [...]

With the conclusion of the international Cassini mission orbiting Saturn and its moons set for Sept. 15, 2017, the spacecraft is poised to soon begin a thrilling two-part endgame. Cassini will enter the first part of this denouement on Nov. 30, 2016, when the spacecraft begins a series of 20 passes just beyond the outer edge of the main rings. These weekly loops around Saturn are called the F [...]

Planet Nine—the undiscovered planet at the edge of the solar system predicted by Caltech's Konstantin Batygin and Mike Brown in January 2016—appears to be responsible for the unusual tilt of the Sun. The large and distant planet may be adding a wobble to the solar system, giving the appearance that the Sun is tilted slightly. “Because Planet Nine is so massive and has an orbit tilted [...]
