Comet C/2013 UQ4 Catalina first looked like an asteroid when NASA NEOWISE team first observed it on December 31, 2013. These exposures were taken that day, when the comet was at a distance of about 2.9 AU from the sun.
Ver en NASA ↗NASA NEOWISE spacecraft viewed comet C/2014 Q2 Lovejoy for a second time on January 30, 2015, as the comet passed through the closest point to our sun along its 14,000-year orbit, at a solar distance of 120 million miles 193 million kilometers.
Ver en NASA ↗These two images show HD 157728, a nearby star 1.5 times larger than the sun. Project 1640 uses new technology on the Palomar Observatory 200-inch Hale telescope near San Diego, Calif., to spot planets.
Ver en NASA ↗Artist impression of Herschel is set against an image captured by the observatory, showing baby stars forming in the Rosette nebula. The bright spots are dusty cocoons containing massive forming stars, each one up to ten times the mass of our own sun.
Ver en NASA ↗This image from NASA Herschel, was taken looking towards a region of our Milky Way galaxy in the Eagle constellation, closer to the galactic center than our sun. Here, we see the outstanding end products of the stellar assembly line.
Ver en NASA ↗This image shows our own back yard, astronomically speaking, from a vantage point about 30 light-years away from the sun. It highlights the population of tiny brown dwarfs recently discovered by NASA WISE. The image simulates actual positions of stars.
Ver en NASA ↗This image from NASA Spitzer Space Telescope shows the nasty effects of living near a group of massive stars: radiation and winds from the massive stars white spot in center are blasting planet-making material away from stars like our sun.
Ver en NASA ↗This chart illustrates relative masses of super-dense cosmic objects, ranging from white dwarfs to supermassive black holes encased in the cores of most galaxies. The first three dead stars left all form when stars more massive than our sun explode.
Ver en NASA ↗This graph of data from NASA Spitzer Space Telescope shows how astronomers located a hot spot on a distant gas planet named upsilon Andromedae b. Termed an exoplanet, it orbits a star beyond our sun, and whips around very closely to its star.
Ver en NASA ↗The Sun blew out a powerful coronal mass ejection (CME) from just around the edge of the Sun (Oct. 14, 2014). The particle cloud expanded around all the Sun in a rough circle, hence the name 'halo' CME. This event was also associated with a fairly strong flar…

Ver en NASA ↗Earth observation taken by the Expedition 39 crew aboard the ISS. Image was released by astronaut on Twitter and downlinked in folder: sun glint.
Ver en NASA ↗The southward-facing side of Building 4220 on Marshall Space Flight Center’s campus is illuminated by the afternoon sun.
Ver en NASA ↗The sun rises behind Cape Canaveral Lighthouse at Cape Canaveral Air Force Station in Florida on Oct. 13, 2020.

Ver en NASA ↗This artist concept depicts a distant hypothetical solar system, similar in age to our own. Looking inward from the system outer fringes, a ring of dusty debris can be seen, and within it, planets circling a star the size of our Sun.
Ver en NASA ↗Although we are used to seeing Saturn moons lit directly by the Sun, sometimes we can catch them illuminated by Saturnshine. Here, NASA Cassini spacecraft see Mimas upper right lit by light reflected off of Saturn.

Ver en NASA ↗As of mid-November, ISON is officially upon us. Using Hubble, we've taken our closest look yet at the innermost region of the comet, where geysers of sublimating ice are fueling a spectacular tail. Made from observations on November 2nd, the image combines …
Ver en NASA ↗This NASA Cassini image of Saturn moon Enceladus backlit by the sun shows the fountain-like sources of the fine spray of material that towers over the south polar region.
Ver en NASA ↗This series of images shows the Martian moon Deimos as it crossed in front of the Sun, as seen by NASA's Curiosity Mars rover on Sunday, March 17, 2019 (the 2,350th Martian day, or sol, of the mission).
