Pluto

One of the first major studies of Pluto’s geology appears in the most recent edition of the Journal of Science. It used data from the New Horizons mission to get a better picture of the dwarf planet’s surface. As Arizona Public Radio’s Justin Regan reports, the study found that so-called “volatile materials” have shaped Pluto’s landscape.

A new study from Northern Arizona University says Pluto’s heart-shaped region is “surprisingly young”—less than 10 million years.

Two California astronomers presented evidence for a new planet beyond Neptune on Wednesday. The prediction could reopen the debate about how a planet is defined, says an astronomer at Lowell Observatory in Flagstaff.

The first formal results about Pluto from NASA’s New Horizons spacecraft appeared in the journal Science last week.

The principal investigator of NASA’s New Horizons mission will give the keynote speech at tonight’s opening events for the Flagstaff Festival of Science.

  Mankind's first close-up look at Pluto did not disappoint Wednesday: The pictures showed ice mountains on Pluto about as high as the Rockies and chasms on its big moon Charon that appear six times deeper than the Grand Canyon.

Especially astonishing to scientists was the total absence of impact craters in a zoom-in shot of one rugged slice of Pluto. They said that suggests that Pluto is geologically active even now and is being sculpted not by collisions with cosmic debris but by its internal heat.

When NASA’s New Horizons spacecraft flew by Pluto yesterday, KNAU’s Melissa Sevigny was patched into mission operations in Maryland. She was talking to some of the Flagstaff scientists who were there to celebrate the big event. It was a reunion for past and present planetary scientists of Lowell Observatory, where Pluto was discovered 85 years ago.

Tomorrow NASA’s New Horizons spacecraft will make its closest approach to Pluto and collect the first-ever close-up images of the dwarf planet. In Flagstaff, where Pluto was discovered, scientists will be waiting to analyze those photographs and other data. But they’re not the only ones. Artists are creating their own interpretations of Pluto, and they’ll use New Horizons for inspiration.

A celestial event last week is helping astronomers from Lowell Observatory in Flagstaff study Pluto’s atmosphere. The ground-based data gives a clearer picture of the ninth classical planet.

After nine years of interplanetary travel, the New Horizons Spacecraft today begins its first observations of Pluto. It will be the first exploration of its kind of the dwarf planet. As Arizona Public Radio’s Justin Regan reports, the mission has special significance for Flagstaff, where Pluto was discovered.
