Science Bulletins: Planck and Herschel: The Sky at Two Scales
Planck and Herschel, a pair of satellites launched in 2009, are examining the sky in tandem to solve some of our biggest cosmological mysteries. Using detectors that read far-infrared light, both satellites are now scanning dust in the Milky Way Galaxy. The do so at different scales. Planck captures large swathes of the sky, while Herschel narrows in on smaller regions at slightly different wavelengths. The new images will give researchers a better understanding of galactic dust and its role in
Science Bulletins: Hubble's Deepest Look at Space
The new camera that Atlantis astronauts installed on the Hubble Space Telescope last summer has spotted the most distant galaxies ever seen in space. Because these galaxies are so far away, their light has taken billions of years to reach Hubble. That means the telescope sees them as they were billions of years ago.
Science Bulletins: Australia's Coral Growth Slows
Corals, like clams, lobster, and sea urchins, are marine calcifiers—they incorporate dissolved minerals from seawater to grow their hard parts. Calcifiers are considered at risk from our increased introduction of carbon dioxide into the atmosphere from the burning of fossil fuels. Carbon dioxide in the air increases the temperature of the ocean by ramping up the greenhouse effect, and the absorption of carbon dioxide into the ocean changes its chemistry so that minerals are less available for
