Venus at Night in Infrared from Akatsuki : Why is Venus so different from Earth? To help find out, Japan launched the robotic Akatsuki spacecraft which entered orbit around Venus late in 2015 after an unplanned five-year adventure around the inner Solar System. Even though Akatsuki was past its original planned lifetime, the spacecraft and instruments were operating so well that much of its original mission was reinstated. Also known as the Venus Climate Orbiter, Akatsuki’s instruments investigated unknowns about Earth’s sister planet, including whether volcanoes are still active, whether lightning occurs in the dense atmosphere, and why wind speeds greatly exceed the planet’s rotation speed. In the featured image taken by Akatsuki’s IR2 camera, Venus’s night side shows a jagged-edged equatorial band of high dark clouds absorbing infrared light from hotter layers deeper in Venus’ atmosphere. The bright orange and black stripe on the upper right is a false digital artifact that covers part of the much brighter day side of Venus. Analyses of Akatsuki images and data has shown that Venus has equatorial jet similar to Earth’s jet stream. via NASA

A torrent of radiation from the hot stars in the cluster NGC 346, at the centre of this Hubble image, eats into denser areas around it, creating a fantasy sculpture of dust and gas. The dark, intricately beaded edge of the ridge, seen in silhouette, is particularly dramatic. It contains several small dust globules that point back towards the central cluster, like windsocks caught in a gale.

These six infrared images of Saturn’s moon Titan represent some of the clearest, most seamless-looking global views of the icy moon’s surface produced so far. The views were created using 13 years of data acquired by the Visual and Infrared Mapping Spectrometer (VIMS) instrument on board NASA’s Cassini spacecraft.

Laguna Starry Sky : Staring toward the heavens, one of the many lagunas in the Atacama Desert salt flat calmly reflects a starry night sky near San Pedro de Atacama, Chile, planet Earth. Cosmic rifts of dust, star clouds, and nebulae of the central Milky Way galaxy are rising in the east, beyond a volcanic horizon. Caught in the six frame panorama serenely recorded in the early morning hours of January 15, planets Jupiter and Mars are close. Near the ecliptic, the bright planets are immersed in the Solar System’s visible band of Zodiacal light extending up and left from the galactic center. Above the horizon to the south (right) are the Large and Small clouds of Magellan, satellite galaxies of the Milky Way. via NASA

We’ve observed binary asteroids before, but it’s incredibly rare to see two that are the same size orbiting each other like this! Like all near-Earth asteroids, it’s believed these are remnants of our solar system’s formation.
