May 1, 2015 — The discovery of a strange exoplanet orbiting very close to a small cool star 500 light years away is challenging ideas about how planets ... read more

Apr. 29, 2015 — Groundbreaking images of the Sun give a first-ever detailed view of the interior structure of umbrae -- the dark patches in the center of sunspots -- revealing dynamic magnetic fields responsible for ... read more

Apr. 29, 2015 — The sun's surface is blisteringly hot at 10,340 degrees Fahrenheit -- but its atmosphere is another 300 times hotter. This has led to an enduring mystery for those who study the sun: What heats ... read more

Apr. 28, 2015 — Scientists have captured the first high-resolution images of the flaring magnetic structures known as solar flux ropes at their point of origin in the sun's ... read more

Apr. 28, 2015 — Astronomers discovered a planetary system orbiting a nearby star that is only 54 light-years away. All three planets orbit their star at a distance closer than Mercury orbits the sun, completing ... read more

Apr. 28, 2015 — The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution ... read more

Apr. 27, 2015 — The E-sail is a novel propellantless technology that was invented in Finland in 2006. The E-sail utilizes long, charged tethers to convert natural solar wind momentum flux into spacecraft ... read more

Thick Atmosphere of Saturn's Moon Titan Fluctuates With Sun's Cycle

Apr. 22, 2015 — Saturn's moon Titan is the only moon in the solar system that has an atmosphere as thick as Earth's, consisting of more than 98 percent nitrogen, roughly 1.4 percent of methane, and smaller ... read more

Apr. 22, 2015 — Researchers can now explain how asteroids are formed. Our own planet also has its origins in the same process, a cosmic ocean of millimeter-sized particles that orbited the young sun, according to ... read more

Apr. 16, 2015 — Astronomers have revealed an extremely powerful magnetic field, beyond anything previously detected in the core of a galaxy, very close to the event horizon of a supermassive black ... read more

Apr. 16, 2015 — Complex organic molecules such as formamide, from which sugars, amino acids and even nucleic acids essential for life can be made, already appear in the regions where stars similar to our Sun are ... read more

Apr. 14, 2015 — NASA's Spitzer Space Telescope has teamed up with a telescope on the ground to find a remote gas planet about 13,000 light-years away, making it one of the most distant planets ... read more

Apr. 13, 2015 — Researchers have long known that there is water in the form of ice on Mars. Now, new research shows that it is possible that there is liquid water close to the surface of Mars. The explanation is ... read more

Apr. 9, 2015 — While no one yet knows what's needed to build a habitable planet, it's clear that the interplay between the sun and Earth is crucial for making our planet livable -- a balance between a sun ... read more

Apr. 9, 2015 — Astronomers compiled a story of our Milky Way's growth by studying galaxies similar in mass to our galaxy, found in deep surveys of the universe. Stretching back more than 10 billion years, the ... read more

Apr. 8, 2015 — Scientists have reconciled the accepted model of the moon's formation with the unexpectedly similar isotopic fingerprints of both bodies. The results suggest that the impact that formed the moon ... read more

Apr. 8, 2015 — For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disc surrounding a young star. The discovery reaffirms that ... read more

Apr. 7, 2015 — A series of images made with the Atacama Large Millimeter/submillimeter Array (ALMA) provides an unprecedented view of the surface of Juno, one of the largest members of our solar system's main ... read more

Apr. 7, 2015 — The sun undergoes a type of seasonal variability with its activity waxing and waning over the course of nearly two years, new research concludes. This behavior affects the peaks and valleys in the ... read more

Apr. 2, 2015 — Astronomers have determined the pre-explosion mass of a white dwarf star that blew up thousands of years ago. The measurement strongly suggests the explosion involved only a single white dwarf, ... read more
