X-Ray Satellite Delivers Surprising New Clues about Formation of Clusters of Sun-like Stars
An important advance in understanding how clusters of stars like our Sun are formed has been made by a team that includes seven Penn State astronomers. One of the clusters that the astronomers studied is shown in this image. Credit: X-ray: NASA/CXC/Penn State/K.Getman, E.Feigelson, M.Kuhn & the MYStIX team; Infrared:NASA/JPL-Caltech
Star Is Discovered To Be a Close Neighbor of the Sun and the Coldest of Its Kind

Solved: Mysteries of a Nearby Planetary System's Dynamics
An illustration of the orbital distances and relative sizes of the four innermost planets known to orbit the star 55 Cancri A (bottom) in comparison with planets in own inner Solar System (top). Both Jupiter and the Jupiter-mass planet 55 Cancri are outside this picture, orbiting their host star with a distance of nearly 5 astronomical units (AU), where one AU is equal to the average distance between the Earth and the Sun.

First Earth-Size Planet Is Discovered in Another Star's "Habitable Zone"
This artist's concept depicts Kepler-186f ,the first validated Earth-size planet to orbit a distant star in the habitable zone -- a range of distance from a star where liquid water might pool on the planet's surface. Credit: NASA Ames/SETI Institute/JPL-Caltech
The Most Precise Measurement Yet of the Expanding Universe Is Achieved by Astronomers of the Sloan Digital Sky Survey

Penn State Hosts Polar Day 2014
Felicity Aston, the first woman to cross Antarctica alone, will speak at Penn State during Polar Day 2014.
WISE Satellite Finds No Evidence for Planet X in Survey of the Sky
This chart shows what types of objects WISE can and cannot see at certain distances from our sun. Bodies with larger masses are brighter, and therefore can be seen at greater distances. For example, if a Jupiter-mass planet existed at 10,000 au, WISE would have easily seen it. But WISE would not have been able to see a Jupiter-mass planet residing at 100,000 au -- it would have been too faint. (To learn more about this image click here.)
