How to watch a livestream of investigation of ice planet Uranus this weekend

By Georgina Torbet October 9, 2021

If you have some free time this weekend, why not tune into an astronomy broadcast showing astronomers investigating the distant ice giant planet Uranus? Experts will be using a ground-based telescope to observe the atmosphere of this lesser-studied planet, located 1.9 billion miles away, and to build out the most detailed infrared map of it to date.

The Royal Astronomical Society is hosting a three-day event livestreaming observations of Uranus using the NASA Infrared Telescope Facility (IRTF) on Mauna Kea in Hawai’i. The observations, led by Leicester Ph.D. student Emma Thomas, are to investigate the mysterious infrared auroras of the planet.

“Over these three days of observations, we will be building up the most detailed infrared map of Uranus that we have ever completed (a full 360 degrees longitude), and by doing this we hope to detect and fully map the southern infrared aurora for the first time ever,” Thomas said. “My area of research is to investigate and fully map the infrared aurorae at Uranus, which is done by analyzing spectra (looking at the different wavelengths of light received from Uranus) from telescopes such as IRTF, Keck (also on Hawai’i), and the Very Large Telescope in Chile.

“The aurora of Uranus has been a long-standing mystery since the first detection of near-infrared emissions back in 1993, but in the last four years we have begun to take the first steps in understanding the weird and wonderful aurorae we see at Uranus.”

How to watch the Uranus livestream

The livestream will include commentary on Uranus from various experts from around the UK and from the Japanese space agency (JAXA). It is running from Friday, October 8 to Sunday, October 10, from 4 a.m. ET (1 a.m. PT) to 11:55 a.m. ET (8:55 a.m. PT) on each day.

You can tune in either using the video link at the top of this page or by heading to the RAS’s YouTube channel. And if that’s too early for you then don’t worry — the streams will be made available at the end of each session so you can catch up with them later.

Three tiny new moons spotted orbiting Uranus and Neptune

Neptune

Our solar system has a few new entries with the recent discovery of three moons of Uranus and Neptune. These ice giant planets are so far away that it is difficult to detect small moons orbiting them, especially when one of the recently discovered moons is the faintest moon ever discovered by a ground-based telescope.

Unlike Jupiter and Saturn, which both have a plethora of moons, Uranus is known to host 28 moons and Neptune just 16. That includes Uranus's new diminutive moon, which is just 5 miles across. Like Uranus' other moons, it will be named after a character from a Shakespeare plays, but a new name has not yet been chosen, so for now it is S/2023 U1.

How to watch NASA and SpaceX launch a private lunar lander mission this week

The Nova-C lunar lander is encapsulated within the fairing of a SpaceX Falcon 9 rocket in preparation for launch, as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign.

NASA will launch the latest mission to the moon late on Tuesday, February 13 (or early on Wednesday, February 14, depending on where you live). As part of its Commercial Lunar Payload Services (CLPS) program, the company Intuitive Machines will launch its first lunar lander, with the aim of delivering science payloads to the surface of the moon.
