. This artist's rendering shows a central black hole interacting with gas in the galaxy's halo to create a self-regulating cycle. In this cycle, jets shooting out of the galaxy's center heat a halo of surrounding gas, controlling the rate at which the gas cools and falls into the galaxy to form stars. NASA/ESA/P. Jeffries (STScI)

Figure 1: Multicolor optical image around the ULX "X-1" (indicated by the arrow) in the dwarf galaxy Holmberg II, located in the direction of the constellation Ursa Major, at a distance of 11 million light-years. The image size corresponds to 1,100 900 light-years at the galaxy. The red color represents spectral line emission from hydrogen atoms. Special Astrophysical Observatory/Hubble Space Telescope

. This image shows the old and new routes of NASA's Mars Curiosity rover and is composed of color strips taken by the High Resolution Imaging Science Experiment on NASA's Mars Reconnaissance Orbiter. This new route provides excellent access to many features in the Murray Formation. And it will eventually pass by the Murray Formation's namesake, Murray Buttes, previously considered to be the entry point to Mt. Sharp. NASA/JPL-Caltech/Univ. of Arizona

. This sample of galaxies, as seen by Hubble, shows chains of star formation in ultraviolet light. This star formation in each galaxy is a product of the action of the jets from a central black hole that controls infalling gas from the galaxy's halo. NASA/ESA/G. Tremblay (Yale Univ.)/R. Mittal (Rochester Institute of Technology and Max Planck Institute for Gravitational Physics)

. This artist's conception portrays the first planet discovered by the Kepler spacecraft during its K2 mission. A transit of the planet was teased out of K2's noisier data using ingenious computer algorithms developed by a CfA researcher. The newfound planet, HIP 116454b, has a diameter of 20,000 miles (two and a half times the size of Earth) and weighs 12 times as much. It orbits its star once every 9.1 days. David A. Aguilar (CfA)

Top Row] . ... The quasars (powered by supermassive black holes) are so compact and bright they make a diffraction-spike pattern in the telescope's optics an optical artifact typically only produced by bright nearby stars. ... Bottom Row] . When the glare of the quasar is subtracted, researchers see evidence for collisions between galaxies. The collisions and mergers gave birth to the quasars by fueling the supermassive black hole at the core of the galaxies. ...

This collage shows images of six different galaxy clusters taken with NASA's Hubble Space Telescope and Chandra X-ray Observatory. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide. ... Using visible-light images from Hubble, the team was able to map the post-collision distribution of stars and also of the dark matter (colored in blue), which was traced through its gravitational lensing effects on background light. ...

. A frame from the simulation of the two colliding "Antennae" galaxies. Here the galaxies are re-shaped after their first encounter. High resolution allows the astrophysicists to explore the smallest details. Stars are formed in the densest regions (yellow and red) under the effect of compressive turbulence. Star formation is more efficient here than in normal galaxies like our Milky Way. F. Renaud/CEA-Sap

This is a series of Hubble Space Telescope pictures of Comet Siding Spring (C/2013 A1) as observed on October 29, 2013; January 21, 2014; and March 11, 2014. The distances from Earth were, respectively, 376 million miles (605 million kilometers), 343 million miles (552 million km), and 353 million miles (568 million km). The solid icy nucleus is too small to be resolved by Hubble, but it lies at the center of a dusty coma that is roughly 12,000 miles (19,000km) across in these images. ...
