Despite a government shutdown, NASA is broadcasting humanity's farthest-ever visit to an object in space. Here's how to watch coverage of the Ultima Thule flyby.

NASA's New Horizons probe is about to explore a mysterious object 1 billion miles beyond Pluto.
The object is known as Ultima Thule, or 2014 MU₆₉, and the flyby is set to occur at 12:33 a.m. ET on Tuesday, New Year's Day.
Ultima Thule will be the most distant object humanity has ever visited.
NASA TV and Johns Hopkins University will host live video broadcasts about the encounter starting on Monday.

NASA is about to fly a nuclear-powered probe past the most distant object humanity has ever dared explore. And you can watch from the comfort of home.

Called Ultima Thule (pronounced "tool-ee"), or 2014 MU₆₉, the object is a total mystery to scientists. Researchers aren't even sure what the space rock looks like, since it's 1 billion miles beyond Pluto. It's also the size of a mountain — about 20 miles across — so Ultima Thule is much too small and too far for telescopes to see clearly.

"If we knew what to expect, we wouldn't be going to Ultima Thule. It's an object we've never encountered before," Alan Stern, the leader of the New Horizons mission, previously told Business Insider. "This is what exploration is about."

In what Stern called a "mind-boggling" maneuver, New Horizons will get its closest to Ultima Thule at 12:33 a.m. ET on Tuesday, New Year's Day. The probe will be moving at about 32,200 mph and come within 2,200 miles of the object.

Along the way, New Horizons w(whichflew past Pluto in July 2015) will take hundreds of photographs and measurements in a highly coordinated sequence.

The first images should arrive late on Tuesday and be published on Wednesday. You'll be able to see those initial images via live video broadcasts.

But because of the limitations of the 13-year-old spacecraft (the probe launched in 2006) and the 4 billion miles of distance, it could take up to two years for New Horizons to beam all of the flyby data back to Earth.

How to watch live video coverage of the Ultima Thule flyby

Johns Hopkins University's Applied Physics Laboratory, which manages the New Horizons mission for NASA, will host a series of live video broadcasts about the encounter.

The segments will be streamed via the laboratory's YouTube channel from Monday through Thursday. NASA Live and NASA TV will also broadcast the segments despite the government shutdown, which President Donald Trump started over funding for a wall along the US-Mexico border, and has sent many NASA workers home.

"NASA will continue to stun the world with its achievements!" Jim Bridenstine, the administrator of NASA, tweeted on Thursday while announcing that NASA TV would stay on the air.

The first Ultima Thule broadcast will be a press conference with Stern and other mission scientists at 2 p.m. on Monday.

At 12:02 a.m. on Tuesday, the Queen guitarist and astrophysicist Brian May will release a song dedicated to the mission. Video coverage will continue through 12:33 a.m., the moment New Horizons flies past Ultima Thule.

Michael Buckley, a representative for the Applied Physics Laboratory, said there would be a video feed of the moment scientists learn that the mission succeeded. He said live coverage should begin on Tuesday around 9:30 a.m., and that the "OK" signal from New Horizons should arrive around 10 a.m. A press conference will follow at 11:30 a.m.

Follow-up briefings to discuss the first close-up photos and scientific results from the historic flyby are scheduled for Wednesday at 2 p.m. and Thursday at 2 p.m.
