Astronomers examining the properties of black hole jets compared 54 gamma-ray bursts with 234 active galaxies classified as blazars and quasars. Surprisingly, the power and brightness of the jets share striking similarities despite a wide range of black hole mass, age, and environment. Regardless of these differences, the jets produce light by tapping into similar percentages of the kinetic energy of particles moving along the jet, suggesting a common underlying physical cause. ...

. This image from ESOтАЩs Very Large Telescope at the Paranal Observatory in Chile shows NGC 1637, a spiral galaxy located about 35 million light-years away in the constellation Eridanus the River. In 1999, scientists discovered a Type II supernova in this galaxy and followed its slow fading over the following years. // ESO

. This plot shows the locations of 150 blazars (green dots) used in the EBL study. The background map shows the entire sky and was constructed from four years of gamma-rays with energies above 10 billion electron volts (GeV) detected by Fermi. The plane of our Milky Way Galaxy runs along the middle of the plot. The Fermi LAT instrument is the first to detect more than 500 sources in this energy range. // Credit: NASA/DOE/Fermi LAT Collaboration

. New observations from NASA's NEOWISE project reveal the hidden nature of centaurs, objects in our solar system that have confounded astronomers for resembling both asteroids and comets. The centaurs, which orbit between Jupiter and Neptune, were named after the mythical half-horse, half-human creatures called centaurs due to their dual nature. This artist's concept shows a centaur creature together with asteroids on the left and comets at right. // NASA/JPL-Caltech

. This color-coded plan view is based on an ESA Mars Express HRSC digital terrain model of the region, from which the topography of the landscape can be derived. The color coding enhances the visibility of the rippling sand dunes which formed in the wind-sheltered sides of the mounds and canyons. Centered at around 40ТАS and 310ТАE, the image has a ground resolution of about 23m per pixel. Taken during revolution 10,736 June 6, 2012. // Credit: ESA/DLR/FU Berlin (G. Neukum)

. This artistтАЩs conception shows a hypothetical habitable planet with two moons orbiting a red dwarf star. Astronomers have found that 6 percent of all red dwarf stars have an Earth-sized planet in the habitable zone, which is warm enough for liquid water on the planetтАЩs surface. Since red dwarf stars are so common, then statistically the closest Earth-like planet should be only 13 light-years away. // David A. Aguilar (CfA)

. This is a NASA Hubble Space Telescope picture of what was first thought to be a comet but is probably an asteroid collision. The inset picture shows a complex structure that suggests the object is not a comet but instead the product of a head-on collision between two asteroids traveling five times faster than a rifle bullet (about three miles per second).

High-Resolution Stereo Camera (HRSC) nadir and color channel data taken during revolution 10,736 on June 6, 2012, by ESAт??s Mars Express have been combined to form a natural-color view of Nereidum Montes. Centered at around 40ТАS and 310ТАE, the image has a ground resolution of about 23m per pixel. ... Undulations in crater floors are commonly seen in mid-latitude regions on Mars and are believed to be a result of glacial movement. ...

The data released today includes infrared spectra of these two stars, shown in the context of the Milky Way Galaxy. ... The white boxes show the infrared spectra of two stars as seen by APOGEE; red lines show where these stars live in the galaxy. The two spectra are from two stars: one in the galactic bulge that is rich in elements heavier than hydrogen, and one further out in the galactic disk that has fewer such heavy elements. ...
