    Antlia Dwarf Galaxy Peppers the Sky with Stars

    March 5, 2012

    The myriad faint stars that comprise the Antlia Dwarf galaxy are more than four million light-years from Earth, but this NASA/ESA Hubble Space Telescope image offers such clarity that they could be mistaken for much closer stars in our own Milky Way. This very faint and sparsely populated small galaxy was only discovered in 1997.

    Ten years ago, on Feb. 19, 2002, the Thermal Emission Imaging System (THEMIS), a multi-band camera on NASA's Mars Odyssey orbiter, began scientific operations at the Red Planet. Since then the camera has circled Mars nearly 45,000 times and taken more than half a million images at infrared and visible wavelengths.

    Scientists have come up with an entirely new way to monitor the health of Earth’s plants from space. In work published in Geophysical Research Letters [1], researchers working at NASA’s Jet Propulsion Laboratory (JPL) and in Germany and Japan report on how measurements taken from space can open a whole new window onto the planet’s carbon cycle.

    Extending the Habitable Zone for Red Dwarf Stars

    Feb. 24, 2012

    Scientists have long thought that planets had to orbit very close to small and dim red dwarf stars in order to be warm enough for life. New research challenges that assumption.
