Images in the visible-light and infrared parts of the spectrum highlight the massive changes roiling the atmosphere of Jupiter.

Supernova remnant SNR1987A is located 166 000 light-years away in the Large Magellanic Cloud. The light from the stellar explosion arrived at Earth in 1987, and has since provided astronomers with a natural laboratory to monitor how the brightness of a supernova changes over time.
Dominating this Hubble Space Telescope view of the remnant are two glowing loops and a very bright ring of shocked hotspots surrounding the location of the now-exploded central star. The material making up these loops and rings was probably ejected from the star earlier in its history and is now being illuminated by the supernova and its shockwave.

NASA's Cassini spacecraft obtained this image of a feature shaped like a hot cross bun in the northern region of Titan (left) that bears a striking resemblance to a similar feature on Venus (right).

Nanoparticle films crack at certain thicknesses (left). By adding layers of thinner films, cracking can be avoided (right).

Two of these stars can be found in the intriguing binary system known as Cygnus OB2 #9. In 2011, NASA's Swift satellite, the European Space Agency's XMM-Newton observatory and several ground-based facilities took part in a campaign to monitor the system as the giant stars raced toward their closest approach.

Heterogenized homogeneous nanocatalysts are sustainable as shown by these TEM images in which there is almost no difference in the cluster size of dendrimer-encapsulated gold nanoclusters (white spots) before (left) and after cyclopropanation reactions.

Today, the state of the art regarding the diagnosis of cancers is focused on tumor identification on sub-cellular scales. Through this technique, the patient-borne cost of the treatment is cut down and the cure success rate is increased considerably. Accordingly, we were highly determined to develop this instrument in order for localization of cellular diagnostics technology in Iran.
