Is this the cutest thing a dwarf planet has ever done?

Does the former planet love us anyway? 

NASA's New Horizons spacecraft captured Pluto's heart-shaped bright spot on Wednesday, the clearest image Earthlings have yet seen of the dwarf planet. At the time, the spacecraft was about 5 million miles from Pluto.

The heart reaches 1200 miles wide across, according to NASA, and will be seen more clearly on the mission's closest approach on July 14.

"The next time we see this part of Pluto at closest approach, a portion of this region will be imaged at about 500 times better resolution than we see today," said Jeff Moore, the geology, geophysics and imaging team leader of NASA’s Ames Research Center, in a statement. "It will be incredible!"

The image officially kicks off the flyby sequence for NASA's New Horizons spacecraft, a daring mission launched nine years ago, when Pluto was the furthest planet in our solar system.

Six months later, the International Astronomical Union reclassified Pluto as a "dwarf planet," but that made no difference to the grand piano-sized spacecraft, locked into its three-billion-mile journey.

The side of Pluto that mission scientists and the public are now seeing is dominated by three regions of varying brightness: the elongated dark "whale" at the equator, the bright heart-shaped area, and a polar region neither bright nor dark.

With this mission, NASA will "round out humankind’s initial exploration of the solar system," writes Matt Hill, a co-investigator on the New Horizons team.

Years ago, the National Academy of Sciences ranked the exploration of Pluto and the Kuiper Belt as the highest priority for solar system exploration. This mission will help scientists understand how Pluto and its five moons “fit in” with the inner rocky planets (Mercury, Venus, Earth, and Mars) and outer gas giants (Jupiter, Saturn, Uranus and Neptune) of our solar system.

Pluto and its largest moon, Charon, are in a third category known as “ice dwarfs.” Like many of the gas giants' moons, but unlike the terrestrial planets, Pluto and Charon consist largely of ice. 

After completing its study of Pluto and its five moons, New Horizons will continue on an extended mission to visit one or two Kuiper Belt Objects, ultimately traveling at least a billion miles beyond the orbit of Neptune to explore space only ever visited by the Voyager missions. 

Pluto may have showed its heart, but New Horizons, like so many for Pluto, must eventually move on.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
