DWARF PLANET PLUTO

Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ Pluto and it's largest moon, Charon, are so far from the Sun and so tiny that they would not seem like promising options for interplanetary colonization. However, they may turn out to be excellent prospects precisely because the double dwarf planet offers some unique options, like space elevators right from surface to surface.

Pluto was discovered by Clyde Tombaugh in 1930. It is not considered a planet anymore because in 2006, astronomers of IAU (International Astronomical Union) gave a new definition to the word 'planet'. According to the new definition, a planet is a celestial body which is in orbit around the sun, is spherical in shape and it has cleared the neighborhood around its orbit. What does this mean? It basically means that using its gravity, a planet should have removed asteroids and dwarf planets, out of its path, thus cleared its neighborhood. Now, Pluto is in orbit around the sun and is spherical in shape. But since Pluto's neighborhood has many other objects and it has not cleared its neighborhood. It is not called a planet anymore.

Pluto might seem like the least likely place to find liquid water, but thanks to New Horizons, we have new information about oceans on the dwarf planet and more from the outer reaches of the solar system!

May 15, 2019 Dr. Ross Beyer (SETI Institute) Pluto’s large moon Charon turned out to be far more interesting than astronomers expected. Pluto was the star of the New Horizons show, but the features on Charon’s surface tell a fascinating tale of how icy worlds could form far from the gravitational influences of the giant planets. There is evidence of a world-wide sub-surface ocean early on, and of global expansion as that ocean froze solid. Dr. Beyer is your expert (and humorous) guide through this story of formation and change in the frozen reaches of the outer Solar System.

I'm sure most of us grew up with the knowledge that Pluto was our solar system's ninth planet. So what changed about the definition? Astrum Answers! SUBSCRIBE for more videos about our other planets.

Some researchers are arguing that Pluto should get its planetary status back.

On July 14, 2015, a spacecraft flew by Pluto for the first time! NASA's New Horizons spacecraft spent 9.5 years making the 3-billion-mile journey to Pluto. When it finally arrived, it took some amazing photos of the dwarf planet's surface. Most notably, the photos revealed that Pluto has a huge, heart-shaped plain, tall mountains and icy volcanoes. The mission also found that Pluto and its largest moon Charon are tidally locked, which means that Pluto's heart is always facing Charon, and the same side of Charon is always facing Pluto. It also seems to be borrowing some atmosphere from Pluto, which appears a big red spot on Charon's north pole.

The largest of Pluto's five moons, Charon, was discovered on June 22, 1978, by James Christy and Robert Harrington at the U.S. Naval Observatory in Flagstaff, Arizona. Read the story: https://www.nasa.gov/feature/charon-at-40-four-decades-of-discovery-on-pluto-s-largest-moon Charon was discovered only about six miles from where Pluto itself was discovered at Lowell Observatory. They weren't even looking for satellites of Pluto – Christy, examining a series of grainy telescope images, trying to refine Pluto's orbit around the Sun. Christy and others tell the story of this amazing scientific find, which fueled Pluto’s transformation from a telescopic dot into an actual planetary system – and a source of many discoveries to come.

According to a new model, days on Earth used to really fly by, and today Pluto has wind-swept dunes made of very weird sand.

A conversation with New Horizons principal investigator Alan Stern and astrobiologist David Grinspoon about their new book, Chasing New Horizons: Inside the Epic First Mission to Pluto. Stern and Grinspoon will share the up-close, inside story of one of the greatest space exploration projects of our time and explore the sheer human ingenuity it took to design, build, and fly this unparalleled mission.

Mars, Pluto, and extrasolar planets. Hosted by Seth Shostak and Molly Bentley. Pluto, we hardly knew ye. Well, not anymore! Until recently, Pluto and Mars were respectively the least-known and best-known planet-sized bodies in our Solar System. Thanks to the New Horizons spacecraft, our picture of Pluto has changed from a featureless dot to a place where we can name the geologic features. And with rovers and orbiters surveying the red planet, we now know much more about Mars than our parents ever did. Examining our planetary backyard has provided insight into the trillion other planets in our galaxy. Dive into a mountain lake and trek though the driest desert on Earth with a scientist who’s had not one but two near-fatal incidents in these extreme environments. Find out what questions compel her to keep returning. And scientists on the New Horizons mission remember why the nail-biting Pluto flyby almost failed at the last minute. Find out what surprises Pluto offered and what the mission might uncover as it heads to its next, outer solar-system target. Also, from Earth-like planets to super Earths and water worlds: a tour of some of Kepler’s most intriguing extrasolar planets.

The debate over Pluto's planethood has resurfaced, and some prominent scientists have a few things to say about it. We all remember what we were doing the day Pluto got kicked out of the solar system's planet club. This happened after it was reclassified from planet to dwarf planet in 2006 when the IAU decided it did not meet the criteria to be considered a planet. Well, New Horizons principle investigator Dr. Alan Stern and astrobiologist David Grinspoon recently declared in a Huffington Post article that Pluto's reclassification was indeed, a mistake. === CONTINUE THE CONVERSATION === Twitter.com/TMRO Facebook.com/TMROTV YouTube.com/TMRO Reddit.com/r/tmro Twitch.tv/TMRO TMRO.tv === OUR REAL-TIME DISCORD CHANNEL === All of the TMRO Shows are created and maintained in our Discord channel.

Pluto was considered a planet for more than 75 years, but in 2006 it was demoted to dwarf planet. Many people were left wondering why the change was made and what the difference was between a planet and a dwarf planet. Come find out in this educational video!

NASA’s New Horizons mission revolutionized our knowledge of Pluto when it flew past that distant world in July 2015. Among its many discoveries were images of strange formations resembling giant blades of ice, whose origin had remained a mystery. Now, scientists have turned up a fascinating explanation for this “bladed terrain”: the structures are made almost entirely of methane ice, and likely formed as a specific kind of erosion wore away their surfaces, leaving dramatic crests and sharp divides.

Join +Fraser Cain and +Pamela Gay for a live episode of Astronomy Cast. We'll record our 30-minute show, and then stay tuned for them to answer questions! This week, we return to our starting point, where Astronomy Cast began: Pluto. 11 years on, we have a whole new appreciate for the dwarf planet Pluto. We've visited it, probed it and taken pictures. It's time for an update.

This issue includes solving mysteries of Pluto, Cassini's Grand Finale, how to find off-season globular clusters, 16 times we didn't find E.T. and more!

Here's what it'd like to fly over Pluto's largest moon Charon.

On July 14, 2015, New Horizons flew by Pluto. Scientists have used the data from the mission so far to uncover active geology, an enormous canyon, a unique case of chemical coloration, and more. What else might we discover as we venture deeper into the Kuiper Belt? Want more on Charon?

Using actual New Horizons data and digital elevation models of Pluto and its largest moon Charon, mission scientists have created flyover movies that offer spectacular new perspectives of the many unusual features that were discovered and which have reshaped our views of the Pluto system – from a vantage point even closer than the spacecraft itself. This dramatic Pluto flyover begins over the highlands to the southwest of the great expanse of nitrogen ice plain informally named Sputnik Planitia. The viewer first passes over the western margin of Sputnik, where it borders the dark, cratered terrain of Cthulhu Macula, with the blocky mountain ranges located within the plains seen on the right. The tour moves north past the rugged and fractured highlands of Voyager Terra and then turns southward over Pioneer Terra -- which exhibits deep and wide pits -- before concluding over the bladed terrain of Tartarus Dorsa in the far east of the encounter hemisphere. Digital mapping and rendering were performed by Paul Schenk and John Blackwell of the Lunar and Planetary Institute in Houston.

The exciting flight over Charon begins high over the hemisphere New Horizons saw on its closest approach, then descends over the deep, wide canyon of Serenity Chasma. The view moves north, passing over Dorothy Gale crater and the dark polar hood of Mordor Macula. The flight then turns south, covering the northern terrain of Oz Terra before ending over the relatively flat equatorial plains of Vulcan Planum and the “moated mountains” of Clarke Montes. Digital mapping and rendering were performed by Paul Schenk and John Blackwell of the Lunar and Planetary Institute in Houston.

NASA's New Horizons mission to Pluto was a success just in time for the international establishment to demote to a dwarf planet. According to CNEt, The new Horizons team is determined to have pluto reclassified. Kirby Runyon thinks that the word "planet" holds a psychological weight. "I want the public to fall in love with planetary exploration as I have," Runyon said. "It drives home the point of continued exploration." Even if a better process for defining a planet could encourage new research and exploration it's impossible to make everyone happ. the debate will continue to rage on so long as Pluto remains a martyr to the process. https://www.cnet.com/news/pluto-planet-new-horizons-alan-stern-iau-carolyn-porco/#ftag=CAD590a51e http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Yes, the question of what makes a planet a "planet" is back in the news after a team of planetary scientists published a new paper challenging the status quo and arguing that Pluto should be a planet again. You may have thought this issue was settled back in 2006 but many problems exist with the current definition. We explain what's wrong with the current version, what this new paper proposes instead and the consequences of the change if it were to be accepted. ::More about this Video:: ► Runyon et al.

Pluto turns out to be far more weird than anyone ever expected, with all kinds of unexplained phenomena on the surface.We sought out some of Europe’s finest ice planet experts to find out more:Pluto has been a mystery since it was discovered in 1930. First called a planet, then re-classified as a dwarf planet in 2006, the more we learn, the more it captures the imagination of scientists like ESA’s Elliot Sefton-Nash.

Alan Stern, principal investigator of NASA’s New Horizons mission, shows the exciting images and science results yielded from the New Horizons mission as the spacecraft flew through the Pluto system, culminating in its closest approach to Pluto on July 14. New Horizon’s flyby revealed hidden wonders like tall water-ice mountains, flowing nitrogen-ice glaciers, and a surface and atmosphere undergoing constant change. Also imaged and examined was Pluto’s giant satellite Charon, as well the tiny moons Nix, Hydra, Kerberos, and Styx. This program is made possible through the generous support of Boeing.

NASA has pieced together a short film that mimics what one would see as they close in on Pluto.

New Horizons’ Pluto flyby might be in the past but the mission is far from over. This is Pluto in a Minute. Of course, Pluto was New Horizons’ primary target, but the mission was never intended to explore only one body in the outer solar system. In fact, the mission was designed to explore not just the Pluto-Charon system, but Pluto-Charon as well as multiple Kuiper Belt Objects. This is according to the 2003 decadal survey that called for a Pluto-Kuiper Belt explorer mission. This was a mission intended to explore the Pluto-Charon system and, to quote, “continue on to do reconnaissance of several additional Kuiper Belt Objects.” So New Horizons always had a Kuiper Belt object as its secondary target. Last summer when New Horizons flew by Pluto there were two options for the future Kuiper Belt flyby and now the team has selected their target. The target the New Horizons team has settled on is called 2014 MU 69, and it was discovered by the Hubble Space Telescope in 2014. The target is a really exciting one because the team suspects that it is made of the same building blocks that have formed all the Kuiper Belt planets and that includes Pluto. Now it must be said that this extended mission is pending approval by NASA. The New Horizons team will have to submit a formal proposal to the space agency later this year. But New Horizons still has a long way to go. The spacecraft will fly by its Kuiper Belt object on January 1 of 2019, which means you’ve got plenty of time to start planning that Kuiper Belt Object themed New Year’s party for 2018.
