A New, "Exceptionally Close" Exploding Star
Swift UVOT images showing M82 before and after the new supernova. The pre-explosion view combines data taken between 2007 and 2013. The view showing SN 2014J merges three exposures taken on Jan. 22, 2014. Mid-ultraviolet light is shown in blue, near-UV light in green, and visible light in red. Credit: NASA/Swift/P. Brown, TAMU

Size of the Universe Now Measured to Within One Percent
An artist's concept of the new measurement of the size of the Universe. The gray spheres show the pattern of the baryon acoustic oscillations from the early Universe. Galaxies today have a slight tendency to align on the spheres -- the alignment is greatly exaggerated in this illustration. By comparing the size of the spheres (white line) to the predicted value, astronomers can determine to 1% accuracy how far away the galaxies are.

X-Ray Factory Revealed in the Center of Our Galaxy
This X-ray image of the galactic center merges Swift XRT observations through 2013. Sgr A* is at center. Low-energy X-rays (300 to 1,500 electron volts) are shown in red, medium-energy (1,500 to 3,000 eV) in green, and high-energy (3,000 to 10,000 eV) in blue. The total exposure time is 12.6 days.Credit: NASA/Swift/N. Degenaar (Univ. of Michigan)

A Blast from Its Past Dates the Youngest Neutron-Star Binary
This composite image shows the energies streaming toward Earth from this object -- X-rays in blue and the radio emission in purple. These energy detections have been overlaid in this image on an optical field of view from the Digitized Sky Survey.
