The White House just released its budget request for FY 2015. Looks like NASA will continue supporting its main priorities, but will they sacrifice SOFIA to fund other missions?
Strongly magnetized rocks on Mars are primarily concentrated in the southern hemisphere. This paper raises a serious objection to the hypothesis that localized dynamo action in the ancient martian core explains this puzzling observation.
In the final months of World War II, Vannevar Bush, director of the Office of Scientific Research and Development, prepared a report that would forever shape federal support of scientific research.
A headline-grabbing paper calculated the prevalence of Earth-sized planets with long orbital periods around Sun-like stars. But are these planets anything like Earth?
Lots of people said lots of interesting things during the anniversary celebration for Caltech’s planetary science department.
Astronomers love to ignore magnetic fields. But they may strongly affect the pattern of atmospheric circulation in hot Jupiters.
Another day, another fight over the future of America’s space agency. The House and the Senate can’t agree about asteroid retrieval, science funding, and much else.
This paper considers the possibility that Earth could suffer a runaway or moist greenhouse effect, which probably turned Venus into a hellish wasteland long ago.
Our simple formula for predicting the probability that an exoplanet will transit might miss something important.
The existence of a conducting layer near the core/mantle boundary has profound implications for the operation of a dynamo in rocky exoplanets and for our ability to detect exoplanetary magnetic fields.
