New window on the early Universe

Scientists see good times approaching for astrophysicists after hatching a new observational strategy to distill detailed information from galaxies at the edge of the Universe. Using two world-class supercomputers, the researchers were able to demonstrate the effectiveness of their approach by simulating the formation of a massive galaxy at the dawn of cosmic time.

Big black holes can block new stars

Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found.

Heavy metal frost? A new look at a Venusian mystery

Venus is hiding something beneath its brilliant shroud of clouds: a first order mystery about the planet that researchers may be a little closer to solving because of a new re-analysis of twenty-year-old spacecraft data.

Explosion first evidence of a hydrogen-deficient supernova progenitor

A new model provides the first characterization of the progenitor for a hydrogen-deficient supernova. The model predicts that a bright hot star, which is the binary companion to an exploding object, remains after the explosion.The findings have important implications for the evolution of massive stars.

Tiny 'nanoflares' might heat the Sun's corona

Why is the Sun's million-degree corona, or outermost atmosphere, so much hotter than the Sun's surface? This question has baffled astronomers for decades. Researchers have now found that miniature solar flares called 'nanoflares' - and the speedy electrons they produce - might partly be the source of that heat, at least in some of the hottest parts of the Sun's corona.

Wobbling of a Saturn moon hints at what lies beneath

Using instruments aboard the Cassini spacecraft to measure the wobbles of Mimas, the closest of Saturn's regular moons, an astronomer has inferred that this small moon's icy surface cloaks either a rugby ball-shaped rocky core or a sloshing sub-surface ocean.

Astronomers make the most reliable remote distance measurement yet

Using the NASA/ESA Hubble Space Telescope astronomers have made what may be the most reliable distance measurement yet of an object that existed in the Universe's formative years. The galaxy is one of the faintest, smallest and most distant galaxies ever seen and measuring its distance with this accuracy was possible due only to the incredibly detailed mapping of how giant galaxy clusters warp the space-time around them.

Cosmic jets of young stars formed by magnetic fields

Astrophysical jets are counted among our Universe?s most spectacular phenomena: From the centers of black holes, quasars, or protostars, these rays of matter sometimes protrude several light years into space. Now, for the first time ever, an international team of researchers has successfully tested a new model that explains how magnetic fields form these emissions in young stars.

Milky Way ransacks nearby dwarf galaxies

Astronomers have discovered that our nearest galactic neighbors, the dwarf spheroidal galaxies, are devoid of star-forming gas, and that our Milky Way Galaxy is to blame.

Construction secrets of a galactic metropolis

Astronomers have used the APEX telescope to probe a huge galaxy cluster that is forming in the early Universe and revealed that much of the star formation taking place is not only hidden by dust, but also occurring in unexpected places. This is the first time that a full census of the star formation in such an object has been possible.

MAVEN spacecraft's first look at Mars holds surprises

NASA's MAVEN spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars and produced unprecedented ultraviolet images of the tenuous oxygen, hydrogen and carbon coronas surrounding the Red Planet.

Rediscovering Venus to find faraway earths

As the search for Earth-like planets wages on, a team of researchers may have found a way to speed up the process. The team is developing a new laser-based technology known as the green astro-comb to obtain information about the mass of a distant planet. Using this information, astronomers will be able to determine whether distant exoplanets are rocky worlds like Earth or less dense gas giants like Jupiter.
