. A new measurement from SDSS-III BOSS reaches twice as far into the past as previous direct measurements of the expansion rate (illustrated by the red dot on the left-hand side). The expansion rate of the universe was slowing down 10 billion years ago, but started to speed up due to the influence of dark energy 6 billion years ago. // Illustration by Z. Rostomian (LBNL)/N. Ross BOSS Lyman-alpha team (LBNL)

The energy source needed to create and maintain the galactic let in galaxy PKS 0521-36 is generated deep within the core of the galaxy, and is far too small to resolved. The favored mechanism behind these cosmic fireworks is a spinning, massive black hole. ... The extraordinary high pressure and temperature generated near the hole would cause some of the in-falling gas to be ejected along the direction of the black hole's spinning axis to create the galactic let. ...

. Gemini Observatory image of Kronberger 61 showing the ionized shell of expelled gas resembling a soccer ball. The light of the nebula here is primarily due to emission from twice-ionized oxygen, and its central star can be seen as the slightly bluer star very close to the center of the nebula. The field of view is 2.2 x 3.4 arcminutes with north up (rotated 22 degrees west of north). Gemini Observatory/AURA

. This microscopic view of a thin slice - less than 1/1,000th of an inch (30 micrometers) thick - of lunar meteorite MIL 05035 reveals the mineral pyroxene (bright mosaicized colors) and maskelynite (dark gray areas), which formed when an intense shock transformed feldspar into glass. MIL 05035's coarse grain size and inclusion of maskelynite are unusual among other lunar specimens. Antarctic Search for Meteorites Program, Case Western Reserve University

The galaxy HFLS3 was found initially as a small red dot in Herschel submillimeter images (main image, and panels on right). Subsequent observations with ground-based telescopes, ranging from optical to millimeter-wave (insets) showed that there are two galaxies appearing very close together. They are at very different distances, however, with one of them, seen in millimeter-wave (inset, blue) being so distant that we are seeing it as it was when the universe was just 880 million years old. ...

. ArtistтАЩs impression of starburst galaxy HFLS3. The galaxy appears as little more than a faint, red smudge in images from ESAтАЩs Herschel space observatory, but appearances can be deceiving for it is making stars more than 2,000 times faster than our Milky Way, one of the highest star formation rates ever seen in any galaxy. Amazingly, it is seen at a time when the universe was less than a billion years old, challenging galaxy evolution theories. // ESAтАУC.Carreau

. Scientists broke open meteorite MIL 05035 in the Antarctic Meteorite Processing Laboratory at NASA's Johnson Space Center to study its composition. The lunar meteorite's interior is pinkish-tan with an unusual granular texture. Each side of the cube shown is slightly less than half an inch (1 centimeter) in length.

. SDSS-III was able to measure the expansion rate of the distant universe by using quasars to probe the distribution of hydrogen along the line of sight from the each quasar (red dots in the upper left) to the 2.5-meter Sloan Foundation Telescope on Earth (abstractly represented as the plane in the lower right). // Illustration by Z.

. Better satellite instruments are improving measurements of solar energy reaching Earth. Exactly determining the contribution of solar fluctuations to rising global temperature is expected to become possible as new instruments, such as the Total Irradiance Monitor above, further refine solar measurements. The device is scheduled to launch next month on NASA's Glory spacecraft. NASA

Byrd Green Bank Telescope in West Virginia. D. Campbell (Cornell)/B. Campbell (Smithsonian)/L. Carter (Smithsonian)

. This image of the Eris simulation shows the stars in the galaxy as observers would see it. Blue colors are regions of recent star formation, while redder regions are associated with older stars.
