Minor mergers are major drivers of star formation Posted: 27 Jun 2016 06:46 PM PDT Around half of the star formation in the local Universe arises from minor mergers between galaxies, according to data from the Sloan Digital Sky Survey. The patch of sky called Stripe 82 is observed repeatedly to produce high-quality images of spiral galaxies. Disruptions to the shapes of these galaxies, caused by interactions with their smallest neighbors, pointed to increased star formation. |
Drones to keep tabs on light pollution Posted: 27 Jun 2016 06:46 PM PDT Astronomers have developed a light, low cost system, deployable on a drone, that could help everyone monitor and control light pollution. |
Meet RobERt, the dreaming detective for exoplanet atmospheres Posted: 27 Jun 2016 06:46 PM PDT Machine-learning techniques that mimic human recognition and dreaming processes are being deployed in the search for habitable worlds beyond our solar system. A deep belief neural network, called RobERt (Robotic Exoplanet Recognition), has been developed by astronomers to sift through detections of light emanating from distant planetary systems and retrieve spectral information about the gases present in the exoplanet atmospheres. |
Moon discovered over dwarf planet Makemake in the Kuiper Belt Posted: 27 Jun 2016 06:44 PM PDT Scientists have discovered an elusive, dark moon orbiting Makemake, one of the 'big four' dwarf planets populating the Kuiper Belt region at the edge of our solar system. |
Mercury's origins traced to rare meteorite Posted: 27 Jun 2016 10:29 AM PDT Geologists trace Mercury's origins to weird, rare meteorite, and find planet cooled dramatically shortly after it formed. |
NASA rover findings point to a more Earth-like Martian past Posted: 27 Jun 2016 09:57 AM PDT Chemicals found in Martian rocks by NASA's Curiosity Mars rover suggest the Red Planet once had more oxygen in its atmosphere than it does now. The findings add to evidence revealing how Earth-like our neighboring planet once was. |
When it comes to brown dwarfs, 'how far?' is a key question Posted: 27 Jun 2016 09:51 AM PDT Brown dwarfs are sometimes called failed stars. They're stars' dim, low-mass siblings and they fade in brightness over time. They're fascinating to astronomers for a variety of reasons, but much about them remains unknown. New work reports the distances of a number of brown dwarfs, as well as low-mass stars. |
Glorious, glowing Jupiter awaits Juno’s arrival Posted: 27 Jun 2016 06:59 AM PDT Stunning new images and the highest-resolution maps to date of Jupiter at thermal infrared wavelengths give a glowing view of Juno's target, a week ahead of the NASA mission's arrival at the giant planet. The maps reveal the present-day temperatures, composition and cloud coverage within Jupiter's dynamic atmosphere, and show how giant storms, vortices and wave patterns shape the appearance of the giant planet. |
Opal discovered in Antarctic meteorite Posted: 27 Jun 2016 06:59 AM PDT Planetary scientists have discovered pieces of opal in a meteorite found in Antarctica, a result that demonstrates that meteorites delivered water ice to asteroids early in the history of the solar system. |
The Martian becomes reality: At least four crops grown on simulated Mars soil are edible Posted: 27 Jun 2016 06:53 AM PDT Scientists are working on growing crops on Mars and moon soil simulants. Just like the real Martian and moon soil these contain heavy metals in almost the same quantities. Four of the crops grown were tested for heavy metal content. No concentrations were detected that would be dangerous for human health. The four crops are therefore safe to eat and, for some heavy metals, the concentrations were even lower than in the crops grown in potting soil. |
Fastest-spinning brown-dwarf star is detected by its bursts of radio waves Posted: 27 Jun 2016 06:50 AM PDT Astronomers have detected what may be the most rapidly rotating, ultra-cool, brown-dwarf star ever seen. The super-fast rotation period was measured by using the 305-meter Arecibo radio telescope -- the same telescope that was used to discover the first planets ever found outside our solar system. The detection emphasizes Arecibo's amazing sensitivity, which has the potential to measure the magnetic fields, which protect life, of potentially habitable planets around other stars. |
Seeds of black holes could be revealed by gravitational waves detected in space Posted: 27 Jun 2016 06:50 AM PDT Gravitational waves captured by space-based detectors could help identify the origins of supermassive black holes, according to new computer simulations of the universe. |
