NASA satellites calling here you come again, Tropical Storm Dolly
(NASA/Goddard Space Flight Center) Tropical Storm Dolly visited Mexico six years ago, and NASA satellite data is calling 'Here you come again,' reminiscent of the famous country singer's hit song, as another storm named Dolly heads for a second landfall in Mexico.

This week From AGU: California earthquake, future Mars rovers, models underestimate ozone
(American Geophysical Union) This week From AGU: California earthquake, future Mars rovers, models underestimate ozone.

Observing the onset of a magnetic substorm
(Wiley) Magnetic substorms, the disruptions in geomagnetic activity that cause brightening of aurora, may sometimes be driven by a different process than generally thought, a new study in the Journal of Geophysical Research: Space Physics shows.

Researchers awarded $1.5 million to develop software to process solar astronomy data on larger scale
(Georgia State University) Researchers in Georgia State University's new Astroinformatics program have been awarded $1.5 million from the National Science Foundation to develop software tools that can process large sets of solar astronomy data and allow scientists to perform analyses on scales and detail levels that have not been possible.

Algal growth a blooming problem Space Station to help monitor
(NASA/Johnson Space Center) The space station's Hyperspectral Imager for the Coastal Ocean (HICO) instrument can help research harmful algal blooms, similar to recent concerns in Lake Erie. HICO provides a way for researchers to see 90 wavelengths of light not visible to humans.

Antarctic sea-level rising faster than global rate
(University of Southampton) A new study of satellite data from the last 19 years reveals that fresh water from melting glaciers has caused the sea-level around the coast of Antarctica to rise by 2 cm more than the global average of 6 cm.

Mixing in star-forming clouds explains why sibling stars look alike
(University of California - Santa Cruz) The chemical uniformity of stars in the same cluster is the result of turbulent mixing in the clouds of gas where star formation occurs, according to a study by astrophysicists at UC Santa Cruz. Their results show that even stars that don't stay together in a cluster will share a chemical fingerprint with their siblings which can be used to trace them to the same birthplace.

Why sibling stars look alike: Early, fast mixing in star-birth clouds
(University of California High-Performance AstroComputing Center) Early, fast, turbulent mixing of gas within giant molecular clouds -- the birthplaces of stars -- means all stars formed from a single cloud bear the same unique chemical 'tag' or 'DNA fingerprint,' write astrophysicists at University of California, Santa Cruz, reporting on the results of computational simulations in the journal Nature, published online on Aug. 31, 2014. Could such chemical tags help astronomers identify our own Sun's long-lost sibling stars?

Mysteries of space dust revealed
(DOE/Argonne National Laboratory) The first analysis of space dust collected by a special collector onboard NASA's Stardust mission and sent back to Earth for study in 2006 suggests the tiny specks open a door to studying the origins of the solar system and possibly the origin of life itself.

NASA sees Hurricane Cristobal racing through North Atlantic
(NASA/Goddard Space Flight Center) Satellite imagery shows Hurricane Cristobal racing through the North Atlantic on Friday, August 29 while losing its tropical characteristics.
