Researchers have announced that six boxes of fruit flies (Drosophila melanogaster) will travel to the International Space Station (ISS) to study the impact of weightlessness on the heart. The fruit flies are scheduled to launch on June 1, 2017, from NASA’s Kennedy Space Center and will travel to the ISS via a SpaceX Dragon spacecraft.
Combined observations from three spacecraft show that Jupiter's brightest auroral features recorded to date are powered by both the volcanic moon Io and interaction with the solar wind.
NASA's Juno mission is rewriting what scientists thought they knew about Jupiter specifically, and gas giants in general, according to a pair of Science papers released today. The Juno spacecraft has been in orbit around Jupiter since July 2016, passing within 3,000 miles of the equatorial cloudtops.
Online volunteers have helped astronomers find a star that exploded 970 million years ago, predating the dinosaurs' time on Earth.
When astronomers took a new look at a famous galaxy with the upgraded Very Large Array, they were surprised by the appearance of a new, bright object that had not appeared in previous images.
In the icy bodies around our solar system, radiation emitted from rocky cores could break up water molecules and support hydrogen-eating microbes. To address this cosmic possibility, a team modeled a natural water-cracking process called radiolysis. They then applied the model to several worlds with known or suspected interior oceans, including Saturn's moon Enceladus, Jupiter's moon Europa, Pluto and its moon Charon, as well as the dwarf planet Ceres.
There's something new to look for in the heavens, and it's called a 'synestia,' according to planetary scientists. A synestia, they propose, would be a huge, spinning, donut-shaped mass of hot, vaporized rock, formed as planet-sized objects smash into each other.
In a paper published in Science, researchers report that Titan, like Mars but unlike Earth, has not undergone any active plate tectonics in its recent past. The upheaval of mountains by plate tectonics deflects the paths that rivers take. The team found that this telltale signature was missing from river networks on Mars and Titan.
NASA's MMS mission studies how electrons spiral and dive around the planet in a complex dance dictated by the magnetic and electric fields, and a new study revealed a bizarre new type of motion exhibited by these electrons.
Astronomers have uncovered a moon orbiting the third largest dwarf planet, 2007 OR10, in the frigid outskirts of our solar system called the Kuiper Belt.
ALMA has made the first complete millimeter-wavelength image of the ring of dusty debris surrounding the young star Fomalhaut. This remarkably well-defined band of rubble and gas is likely the result of exocomets smashing together near the outer edges of a planetary system 25 light-years from Earth.
Human activities, like nuclear tests and radio transmissions, have been changing near-Earth space and weather, and have created artificial radiation belts, damaged satellites and induced auroras.
Heavy rain on Mars reshaped the planet's impact craters and carved out river-like channels in its surface billions of years ago, according to a new study. Scientists show that changes in the atmosphere on Mars made it rain harder and harder, which had a similar effect on the planet's surface as we see on Earth.
NASA's Mars Exploration Rover Opportunity has reached the main destination of its current two-year extended mission -- an ancient fluid-carved valley incised on the inner slope of a vast crater's rim.
One million miles from Earth, a NASA camera is capturing unexpected flashes of light reflecting off our planet.
Plumes of vapor generated by ancient impacts on Mars created tornado-like winds possibly swirling at more than 500 miles per hour, which explain mysterious streaks seen near large impact craters on the Martian surface.
Astronomers have produced a highly detailed image of the Crab Nebula, by combining data from telescopes spanning nearly the entire breadth of the electromagnetic spectrum.
Human-made space radiation has been produced in new research, which could help to make space exploration safer, more reliable and more extensive.
A kind of solar storm has puzzled scientists for its lack of typical warning signs: They seem to come from nowhere, and scientists call them stealth CMEs. Now, scientists have developed a model simulating their evolution.
A chemical engineer who normally develops new ways to fabricate microprocessors in computers has figured out how to explain a nagging mystery in space -- why comets expel oxygen gas, the same gas we humans breathe.
