This Hubble image shows the remnant of SN 1987A within the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The image was taken by Hubble’s Wide Field Camera 3 (WFC3) in January 2017. SN 1987A is located in the center of the image amidst a backdrop of stars. The bright ring around the central region of the exploded star is composed of material ejected by the star about 20,000 years before the actual explosion took place. The supernova is surrounded by gaseous clouds. The clouds’ red color represents the glow of hydrogen gas. The colors of the foreground and background stars were added from observations taken by Hubble’s Wide Field Planetary Camera 2 (WFPC2). Image credit: NASA / ESA / R.

NGC 5907 X-1 is in the spiral galaxy NGC 5907, which is also known as the Knife Edge Galaxy or Splinter Galaxy. This image comprises X-ray emission data (blue/white) from ESA’s XMM-Newton space telescope and NASA’s Chandra X-ray observatory, and optical data from the Sloan Digital Sky Survey. The inset shows the X-ray pulsation of the spinning neutron star, which has a period of 1.13 sec, as determined by XMM-Newton’s European Photon Imaging Camera.

NASA’s Fermi telescope has detected a gamma-ray excess (shown in yellow-white) at the center of the Andromeda galaxy that’s similar to a signature Fermi previously detected at the center of our own Milky Way Galaxy. Scientists think the signal could be produced by a variety of processes, including a population of pulsars or even dark matter.

This Cassini view shows four dusty strands of Saturn’s F ring: the central strand is the core of the ring; the other strands are not independent at all, but are actually sections of long spirals of material that wrap around the gas giant; the material in the spirals was likely knocked out from the F ring’s core during interactions with a small moon.

Astronomers combined data from ALMA’s 7- and 12-m antennas to produce the sharpest possible image of RX J1347.5–1145, the center of which shows up here in the dark ‘hole’ in the ALMA observations. The energy distribution of the CMB photons shifts and appears as a temperature decrease at the wavelength observed by ALMA, hence a dark patch is observed in this image at the location of the cluster. The optical image of RX J1347.5–1145 was taken with Hubble. Image credit: NASA / ESA / Hubble / T. Kitayama, Toho University / ALMA.

This enhanced color composite image, made with data from NASA’s Dawn spacecraft, shows the area around Ernutet crater, which is about 32 miles (52 km) in diameter and is located in the northern hemisphere. The bright red portions appear redder with respect to the rest of Ceres. In the new study, planetary researchers found that these red areas around Ernutet are associated with evidence of organic material. Images taken using blue (440 nm), green (750 nm) and infrared (960 nm) spectral filters were combined to create the view. Image credit: NASA / JPL-Caltech / UCLA / MPS / DLR / IDA.

This artist’s rendering illustrates a conceptual design for a potential future mission to land a robotic probe on the surface of Europa. The lander is shown with a sampling arm extended, having previously excavated a small area on the surface. The circular dish on top is a dual-purpose high-gain antenna and camera mast, with stereo imaging cameras mounted on the back of the antenna. Three vertical shapes located around the top center of the lander are attachment points for cables that would lower the rover from a sky crane, which is envisioned as the landing system for this mission concept.

Cyclones swirl around the south pole, and white oval storms can be seen near the limb -- the apparent edge of the planet -- in this image of Jupiter’s south polar region taken by the JunoCam imager aboard NASA’s Juno spacecraft. The image was acquired on February 2, 2017, from an altitude of 47,600 miles (76,600 km) above Jupiter’s swirling cloud deck. Prior to the Feb. 2 flyby, the public was invited to vote for their favorite points of interest in the Jovian atmosphere for JunoCam to image. The point of interest captured here was titled ‘Jovian Antarctica’ by a member of the public, in reference to Earth’s Antarctica. Image credit: NASA / JPL-Caltech / SwRI / MSSS.

Ahuna Mons, Ceres’ lonely mountain, is seen in this simulated perspective view. The elevation has been exaggerated by a factor of two. The view was made using enhanced-color images from NASA’s Dawn orbiter. Images taken using blue (440 nm), green (750 nm) and infrared (960 nm) spectral filters were combined to create the view. The spacecraft’s framing camera took the images from Dawn’s low-altitude mapping orbit, from an altitude of 240 miles (385 km) in August 2016.

This Cassini image features a density wave in Saturn’s A ring (at left) that lies around 83,575 miles (134,500 km) from Saturn. Density waves are accumulations of particles at certain distances from the planet. This feature is filled with clumpy perturbations, which researchers informally refer to as ‘straw.’ The wave itself is created by the gravity of Saturn’s moons Janus and Epimetheus, which share the same orbit around the gas giant. Elsewhere, the scene is dominated by ‘wakes’ from a recent pass of the ring moon Pan. The image was taken in visible light with Cassini’s wide-angle camera on December 18, 2016. The view was obtained at a distance of approximately 34,000 miles (56,000 km) from the rings and looks toward the unilluminated side of the rings.
