Finding hints of gravitational waves in the stars
Scientists have shown how gravitational waves -- invisible ripples in the fabric of space and time that propagate through the universe -- might be 'seen' by looking at the stars. The new model proposes that a star that oscillates at the same frequency as a gravitational wave will absorb energy from that wave and brighten, an overlooked prediction of Einstein's 1916 theory of general relativity. The study contradicts previous assumptions about the behavior of gravitational waves.

NASA's Newest Mars Mission Spacecraft Enters Orbit around Red Planet
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars' orbit at 7:24 p.m. PDT (10:24 p.m. EDT) Sunday, Sept. 21, where it now will prepare to study the Red Planet's upper atmosphere as never done before. MAVEN is the first spacecraft dedicated to exploring the tenuous upper atmosphere of Mars.

Gravitational waves according to Planck
Scientists of the Planck collaboration, and in particular the Trieste team, have conducted a series of in-depth checks on the discovery recently publicized by the Antarctic Observatory, which announced last spring that it had detected some direct effects of gravitational waves on cosmic microwave background radiation, a potentially groundbreaking discovery in the field of cosmology. Analysis of the Planck satellite data demonstrates that the effect of contaminating sources, such as gases from our galaxy, cannot be ruled out.

Infant solar system shows signs of windy weather
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed what may be the first-ever signs of windy weather around a T Tauri star, an infant analog of our own Sun. This may help explain why some T Tauri stars have disks that glow weirdly in infrared light while others shine in a more expected fashion.

Breezy science, plant studies and more head to space station on SpaceX-4
Imagine a dragon flying through the heavens on mighty, outstretched wings. The majestic beast knows the currents of winds and how to harness their power as it soars above the clouds. SpaceX's real Dragon- the company's spacecraft that transports supplies and science to the International Space Station (ISS) - will deliver, and later return, new technology, biology and biotechnology and Earth and space science research to the orbiting outpost.
