Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency, the National Science Foundation, and the Sloan Foundation.

Sometimes first impressions are poor ones. When the Voyager 2 spacecraft whizzed by Uranus in 1986,
the close-up view of the gas giant revealed what appeared to a be a relatively featureless ball.
By that point, scientists were used to seeing bright colors and bands on Jupiter and Saturn.
Uranus wasn?t quite deemed uninteresting, but the lack of activity was something that was usually remarked upon when describing the planet.

Uranus’ Rings are Surprisingly Bright in Thermal Emissions
During the late 1970s, scientists made a rather interesting discovery about the gas giants of the Solar System. Thanks to ongoing observations using improved optics, it was revealed that gas giants like Uranus – and not just Saturn – have ring systems about them. The main difference is, these ring systems are not easily visible from a distance using conventional optics and require exceptional timing to see light being reflected off of them.

X-rays offer a unique insight into the astronomical world. Invisible to the naked eye, most commonly they are thought of as the semi-dangerous source of medical scans. However, X-ray observatories, like the Chandra X-ray Observatory are capable of seeing astronomical features that no other telescope can. Recently scientists found some of those X-rays coming from a relatively unexpected source – Uranus. A combined X-ray and optical view of Uranus Credit: NASA / CXO / University College London / W.

You think only Saturn has rings? Well, think again. Rings are actually extremely common in our Solar System - they're all over the place. So which planets - and other objects - sport rings?
This is a composite image of Uranus by Voyager 2 and two different observations made by Hubble — one for the ring and one for the auroras. These auroras occurred in the planet’s southern latitudes near the planet’s south magnetic pole. Like Jupiter and Saturn, hydrogen atoms excited by blasts of the solar wind are the cause for the glowing white patches seen in both photos. Credit: NASA/ESA

Astronomers think they know how Uranus got flipped onto its side. According to detailed computer simulations, a body about twice the size of Earth slammed into Uranus between 3 to 4 billion years ago. The impact created an oddity in our Solar System: the only planet that rotates on its side.

A simulation showing a grazing giant impact between a massive object and the young Uranus. Research led by Durham University, UK, confirms that a massive object roughly twice the size of Earth hit Uranus about 4 billion years ago and caused the planet's unusual tilt. The collision could explain Uranus' freezing temperatures. The clock in the top left of the animation shows hours since the start of simulation. Credit: Jacob Kegerreis/Durham University

Miranda, a small, icy moon of Uranus, is one of the most visually striking and enigmatic bodies in the solar system.
Despite its relatively small size, Miranda appears to have experienced an episode of intense resurfacing that
resulted in the formation of at least three remarkable and unique surface features -- polygonal-shaped regions called coronae.

In 1610, Galileo’s observed f0ur satellites orbiting the distant gas giant of Jupiter.
This discovery which would ignite a revolution in astronomy, and encouraged further examinations
of the outer Solar System to see what other mysteries it held. In the centuries that followed,
astronomers not only discovered that other gas giants had similar systems of moons, but that these systems were rather extensive.

? Moon of Uranus: Bianca. 51km diameter. Discovered by Voyager 2 in 1986. Named after the sister of Katherine in Shakespeare's play
'The Taming of the Shrew'. Bianca belongs to the Portia Group of satellites, which also includes Cressida, Desdemona, Juliet, Portia,
Rosalind, Cupid, Belinda and Perdita. Its surface is grey in color. Virtually nothing is known about it, and no pictures exist showing
what it actually looks like. Third closest moon to Uranus. CGI render by mr-nerb.

Interesting Facts:
The surface of Umbriel has far more and larger craters than do Ariel and Titania,
ranging in diameter from a few kilometers to several hundred. The largest known crater on the surface is Wokolo,
which is 210 km in diameter. Wunda, a crater with a diameter of about 131 kilometers,
is the most noticeable surface feature, due to the ring of bright material on its floor (which scientists think are from the impact).
The southern hemisphere of Umbriel displays heavy cratering in this Voyager 2 image, taken Jan. 24, 1986.

Because they are in the planet�s equatorial plane, Uranus� satellites also experience these changes.
This means that Umbriel�s north and south poles spend 42 years in light and then 42 years in darkness before repeating the cycle.
In fact, the Voyager 2 flyby coincided with the southern hemisphere�s 1986 summer solstice, when nearly the entire northern hemisphere was in darkness.

Like all of the Solar Systems’ gas giants, Uranus has an extensive system of moons.
In fact, astronomers can now account for 27 moons in orbit around Uranus. Of these,
none are greater in size, mass, or surface area than Titania. One of the first moon’s to be discovered around Uranus,
this heavily cratered and scarred moon was appropriately named after the fictional Queen of the Fairies.

In a recent study published in The Planetary Science Journal, a pair of researchers led by The Carl Sagan Center at the SETI Institute in California investigated the potential origin for the thick regolith deposits on Uranus’ moon, Miranda. The purpose of this study was to determine Miranda’s internal structure, most notably its interior heat, which could help determine if Miranda harbors—or ever harbored—an internal ocean.
