Watch Live Today! Hubble Experts Talk Interstellar Comet Borisov

The interstellar comet 2I/Borisov just made its closest approach to the sun, and it's currently on its way back out of the solar system. Visible in small telescopes — as well as more high-tech instruments like NASA's Hubble Space Telescope — the fuzzy comet's passage through the inner solar system has offered a celestial spectacle for professional astronomers and casual skywatchers. 

On Friday (Dec. 13), Hubble scientists will discuss the interstellar comet in a series of live interviews that will stream live on NASA TV from 6 a.m. to 12 p.m. EST (1100-1700 GMT). You can watch it live in the window above, courtesy of NASA TV, or directly via the NASA TV Media Channel on YouTube

From NASA:

"The Hubble Space Telescope just captured a new image of the first known interstellar comet as it speeds towards our Sun. The comet named 2I/Borisov is an ancient ball of ice, rock and dust that formed in a distant star system. Scientists are clamoring to study this frozen time capsule shrouded in mystery, looking for clues of what may lie beyond our solar system.

"Chat with Hubble scientists from 6:00 a.m. to 12:00 p.m. EST on Friday, December 13th, to learn about the out-of-this-solar-system discovery, find out what this comet can teach us about what lies beyond our own solar system and learn how your viewers may be able to see this interstellar visitor for themselves.

"This comet is the second confirmed interstellar object visiting our solar system, and likely the first interstellar comet ever discovered. Scientists are taking advantage of this fleeting opportunity to observe this ancient ball of ice and dust before it departs our solar system forever."

Live HD Views of Earth from Space

You can watch live, high-definition views of Earth from the International Space Station thanks to NASA's High Definition Earth Viewing experiment (HDEV). This live video provides alternating views from four of the station's external cameras nearly 24/7, with the exception of regular and temporary dropouts that occur when the station switches its connection between different communications satellites. Watch it live in the window above, courtesy of NASA TV. 

From NASA:

"Behold, the Earth! See live views of Earth from the International Space Station coming to you by NASA's High Definition Earth Viewing (HDEV) experiment.

"While the experiment is operational, views will typically sequence through the different cameras. If you are seeing a black image, the Space Station is on the night side of the Earth. If you are seeing an image with text displayed, the communications are switching between satellites and camera feeds are temporarily unavailable. Between camera switches, a black & gray slate will also briefly appear.

"The experiment was activated on April 30, 2014 and is mounted on the External Payload Facility of the European Space Agency’s Columbus module. This experiment includes several commercial HD video cameras aimed at the Earth which are enclosed in a pressurized and temperature controlled housing. To learn more about the HDEV experiment, visit: https://eol.jsc.nasa.gov/ESRS/HDEV/

"Please note: The HDEV cycling of the cameras will sometimes be halted, causing the video to only show select camera feeds. This is handled by the HDEV team, and is only scheduled on a temporary basis. Nominal video will resume once the team has finished their scheduled event."

'ISS Live!' Tune in to the International Space Station

Find out what the astronauts and cosmonauts aboard the International Space Station are up to by tuning in to the "ISS Live" broadcast. Hear conversations between the crew and mission controllers on Earth and watch them work inside the U.S. segment of the orbiting laboratory. When the crew is off duty, you can enjoy live views of Earth from Space. You can watch and listen in the window below, courtesy of NASA.

From NASA:

"Live video from the International Space Station includes internal views when the crew is on-duty and Earth views at other times. The video is accompanied by audio of conversations between the crew and Mission Control. This video is only available when the space station is in contact with the ground. During 'loss of signal' periods, viewers will see a blue screen.

"Since the station orbits the Earth once every 90 minutes, it experiences a sunrise or a sunset about every 45 minutes. When the station is in darkness, external camera video may appear black, but can sometimes provide spectacular views of lightning or city lights below."

    It could also be more issues for stargazing too :)
