NASA's Hubble, New Horizons Team Up for a Simultaneous Look at Uranus

A two panel image. The left panel is Hubble's actual view of Uranus – the planet is a light blue sphere, with a white circle covering the right half of the planet (the southern pole). The right panel is the actual view of Uranus from New Horizons. The planet appears as a tiny whiteish dot.

Summary

Learnings provide insights into capabilities needed for direct-imaging of exoplanets

Uranus has been described as mysterious, strange, and fairly unknown to those of us here on Earth. However, in astronomy, these terms are pretty relative. Compared to the remote, dark stretches of the early universe or oddball exoplanets dozens of light-years from our solar system, researchers actually know a lot about Uranus. 

NASA's Hubble Space Telescope is among the observatories that can view the planet in high resolution, showing up-close details of the planet's atmospheric features. 

Astronomers have now taken advantage of this viewpoint in a new way. They viewed Uranus in high resolution with Hubble, and at the same time, with the New Horizons spacecraft from 6.5 billion miles away, where the planet appears as just a splotch. This combined perspective can help teach them more about what to expect while imaging planets around other stars — Hubble provides context for what the atmosphere is actually doing when it was observed with New Horizons.

NASA's Hubble Space Telescope and New Horizons spacecraft simultaneously set their sights on Uranus recently, allowing scientists to make a direct comparison of the planet from two very different viewpoints. The results inform future plans to study like types of planets around other stars. Astronomers used Uranus as a proxy for similar planets beyond our solar system, known as exoplanets, comparing high-resolution images from Hubble to the more-distant view from New Horizons. This combined perspective will help scientists learn more about what to expect while imaging planets around other stars ...
