Solar System 10 Things: Looking Back at Pluto

In July 2015, we saw Pluto up close for the first time and—after three years of intense study—the surprises keep coming. “It’s clear,” says Jeffery Moore, New Horizons’ geology team lead, “Pluto is one of the most amazing and complex objects in our solar system.”

1. An Improving View

image

These are combined observations of Pluto over the course of several decades. The first frame is a digital zoom-in on Pluto as it appeared upon its discovery by Clyde Tombaugh in 1930. More frames show of Pluto as seen by the Hubble Space Telescope. The final sequence zooms in to a close-up frame of Pluto taken by our New Horizons spacecraft on July 14, 2015.

2. The Heart

image

Pluto’s surface sports a remarkable range of subtle colors are enhanced in this view to a rainbow of pale blues, yellows, oranges, and deep reds. Many landforms have their own distinct colors, telling a complex geological and climatological story that scientists have only just begun to decode. The image resolves details and colors on scales as small as 0.8 miles (1.3 kilometers). Zoom in on the full resolution image on a larger screen to fully appreciate the complexity of Pluto’s surface features.

3. The Smiles

July 14, 2015: New Horizons team members Cristina Dalle Ore, Alissa Earle and Rick Binzel react to seeing the spacecraft’s last and sharpest image of Pluto before closest approach.

4. Majestic Mountains

Solar System 10 Things: Looking Back At Pluto

Just 15 minutes after its closest approach to Pluto, the New Horizons spacecraft captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto’s horizon. The backlighting highlights more than a dozen layers of haze in Pluto’s tenuous atmosphere. The image was taken from a distance of 11,000 miles (18,000 kilometers) to Pluto; the scene is 780 miles (1,250 kilometers) wide.

5. Icy Dunes

image

Found near the mountains that encircle Pluto’s Sputnik Planitia plain, newly discovered ridges appear to have formed out of particles of methane ice as small as grains of sand, arranged into dunes by wind from the nearby mountains.

6. Glacial Plains

image

The vast nitrogen ice plains of Pluto’s Sputnik Planitia – the western half of Pluto’s “heart”—continue to give up secrets. Scientists processed images of Sputnik Planitia to bring out intricate, never-before-seen patterns in the surface textures of these glacial plains.

7. Colorful and Violent Charon

image

High resolution images of Pluto’s largest moon, Charon, show a surprisingly complex and violent history. Scientists expected Charon to be a monotonous, crater-battered world; instead, they found a landscape covered with mountains, canyons, landslides, surface-color variations and more.

8. Ice Volcanoes

image

One of two potential cryovolcanoes spotted on the surface of Pluto by the New Horizons spacecraft. This feature, known as Wright Mons, was informally named by the New Horizons team in honor of the Wright brothers. At about 90 miles (150 kilometers) across and 2.5 miles (4 kilometers) high, this feature is enormous. If it is in fact an ice volcano, as suspected, it would be the largest such feature discovered in the outer solar system.

9. Blue Rays

Solar System 10 Things: Looking Back At Pluto

Pluto’s receding crescent as seen by New Horizons at a distance of 120,000 miles (200,000 kilometers). Scientists believe the spectacular blue haze is a photochemical smog resulting from the action of sunlight on methane and other molecules in Pluto’s atmosphere. These hydrocarbons accumulate into small haze particles, which scatter blue sunlight—the same process that can make haze appear bluish on Earth.

10. Encore

image

On Jan. 1, 2019, New Horizons will fly past a small Kuiper Belt Object named MU69 (nicknamed Ultima Thule)—a billion miles (1.5 billion kilometers) beyond Pluto and more than four billion miles (6.5 billion kilometers) from Earth. It will be the most distant encounter of an object in history—so far—and the second time New Horizons has revealed never-before-seen landscapes.

Thousands Of Stars In The Orion Nebula

Thousands of Stars in the Orion Nebula

Close inspection of the 2006 Hubble Space Telescope color mosaic of the Orion Nebula (M42) reveals numerous treasures that reside within the nearby, intense star- forming region. Southwest of the Trapezium stars located in the center of the nebula, a stunning Hubble Heritage portrait captures a variety of intricate objects. Deeply contrasting areas of light and dark blend with a palette of colors mix to form rich swirls and fluid motions that would make even the best artists stand back and admire their work.

Visible slightly bottom right center is the star LL Orionis (LL Ori), originally release by the Hubble Heritage Project in 2002. The delicate bow shock that surrounds LL Ori points towards the stream of gas flowing slowly away from the center of the Orion Nebula, near the Trapezium stars located off the image to the upper left. Close examination of the ends of the bow shock show secondary shocks that are formed as a two-sided jet of gas flowing away from this forming star at high velocity strikes the stream of low velocity gas from the center. To the right of LL Ori, a ghostly veil of material hangs thick and dark, obscuring portions of the nebula behind it.

Candy Cane of Cosmic Proportions

Imagine how long it would take to eat a candy cane that’s a thousand trillion miles tall! 😋

image

Scientists peering into the center of our Milky Way galaxy found this 190-light-year tall “candy cane,” but (sadly) it is not a peppermint treat. It does contain other goodies, though. They have found huge collections of material, called giant molecular clouds, where stars are being born. And there are magnetic fields that might be evidence of a bubble from an outburst in our galactic center long ago.

image

The full image shows our galaxy’s center in infrared (blue), radio (red) and microwave (“minty” green) light. The picture essentially color codes different ways light is produced. The blue and cyan regions show us cool dust where star formation has just begun. Yellow features show more-established star “factories.” Red reveals places where electrically charged gas interacts with magnetic fields.

This image includes newly published observations using an instrument designed and built at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, called the Goddard-IRAM Superconducting 2-Millimeter Observer (GISMO). It was used with a 30-meter radio telescope located on Pico Veleta, Spain, operated by the Institute for Radio Astronomy in the Millimeter Range headquartered in Grenoble, France. The image shows a region about 750 light-years wide.

Find out more about this image and what we can learn from studying star factories!

What Do You Get When You Combine A Doctor, Engineer & Astronaut? Mae Carol Jemison! Dr. Jemison Flew

What do you get when you combine a doctor, engineer & astronaut? Mae Carol Jemison! Dr. Jemison flew on Space Shuttle Endeavour in Sept 1992 to become the 1st African-American woman in space. The 7-day, 22-hour flight was the 50th Shuttle mission & had a focus on conducting microgravity investigations in materials & life sciences. Dr. Jemison also holds an amazing 9 doctorates; don’t know how that’s humanly possible; getting my BA was tough enough!
