Hubble solves cosmic 'whodunit' with interstellar forensics
On the outskirts of our galaxy, a cosmic tug-of-war is unfolding-and only NASA's Hubble Space Telescope can see who's winning.

Mars' oceans formed early, possibly aided by massive volcanic eruptions
A new theory about how oceans and volcanoes interacted during the early history of Mars supports the idea that liquid water was once abundant and may still exist underground. Geophysicists propose that the oceans originated several hundred million years earlier than thought, as the volcanic province Tharsis formed, and that greenhouse gases enabled the oceans. The theory predicts smaller oceans, more in line with estimates of water underground and at the poles today.

Scientists detect radio echoes of a black hole feeding on a star
A scientist has detected radio echoes of a black hole feeding on a star, suggesting black hole emits a jet of energy proportional to the stellar material it gobbles up.

Space radiation more hazardous: Implication sfor astronauts and satellites
It might sound like something from a science fiction plot - astronauts traveling into deep space being bombarded by cosmic rays - but radiation exposure is science fact. As future missions look to travel back to the moon or even to Mars, new research cautions that the exposure to radiation is much higher than previously thought and could have serious implications on both astronauts and satellite technology.

Jupiter's atmospheric beauty is more than skin deep
In the year and a half NASA's Juno spacecraft has been orbiting Jupiter, the scientists have discovered that the orange and white bands that characterize Jupiter's outer atmosphere extend thousands of miles into the gas giant's atmosphere.

Double or nothing: Astronomers rethink quasar environment
Astronomers have identified nearly 200 'protoclusters,' the progenitors of galaxy clusters, in the early Universe, about 12 billion years ago, about ten times more than previously known. They also found that quasars don't tend to reside in protoclusters; but if there is one quasar in a protocluster, there is likely a second nearby. This result raises doubts about the relation between protoclusters and quasars.

Arrested development: Hubble finds relic galaxy close to home
Astronomers have put NASA's Hubble Space Telescope on an Indiana Jones-type quest to uncover an ancient 'relic galaxy' in our own cosmic backyard.

15 new planets confirmed around cool dwarf stars
Scientists report the existence of 15 new planets -- including one 'super-Earth' that could harbor liquid water -- orbiting small, cool stars near our solar system. These stars, known as red dwarfs, are of enormous interest for studies of planetary formation and evolution.

Three NASA satellites recreate solar eruption in 3-D
Scientists have developed a model that simulates how shocks following coronal mass ejections, or CMEs, propagate from the sun -- an effort made possible only by combining data from three different NASA satellites.

Making a splash in search for interstellar water
Water is crucial for life, but how do you make water? Cooking up some H2O takes more than mixing hydrogen and oxygen. It requires the special conditions found deep within frigid molecular clouds, where dust shields against destructive ultraviolet light and aids chemical reactions. NASA's James Webb Space Telescope will peer into these cosmic reservoirs to gain new insights into the origin and evolution of water and other key building blocks for habitable planets.

New 3-D measurements improve understanding of geomagnetic storm hazards
Measurements of the three-dimensional structure of Earth, as opposed to the one-dimensional models typically used, can help scientists more accurately determine which areas of the United States are most vulnerable to blackouts during hazardous geomagnetic storms.

First laboratory simulation of exoplanet atmospheric chemistry
Scientists have conducted the first lab experiments on haze formation in simulated exoplanet atmospheres, an important step for understanding upcoming observations of planets outside the solar system with the James Webb Space Telescope.

NASA Juno finds Jupiter's jet-streams are unearthly
Data collected by NASA's Juno mission to Jupiter indicate that the atmospheric winds of the gas-giant planet run deep into its atmosphere and last longer than similar atmospheric processes found here on Earth.

Weather satellites aid search and rescue capabilities
The same satellites that identify severe weather can help save you from it. NOAA's GOES series satellites carry a payload supported by NASA's Search and Rescue (SAR) office, which researches and develops technologies to help first responders locate people in distress worldwide, whether from a plane crash, a boating accident or other emergencies.

ALMA reveals inner web of stellar nursery
New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create this stunning image showing a web of filaments in the Orion Nebula. These features appear red-hot and fiery in this dramatic picture, but in reality are so cold that astronomers must use telescopes like ALMA to observe them.

Hubble finds huge system of dusty material enveloping the young star HR 4796A
Astronomers have used NASA's Hubble Space Telescope to uncover a vast, complex dust structure, about 150 billion miles across, enveloping the young star HR 4796A.

Comet 'Chury's' late birth
Comets which consist of two parts, like Chury, can form after a catastrophic collision of larger bodies. Such collisions may have taken place in a later phase of our solar system, which suggests that Chury can be much younger than previously assumed.
