Colors Of Earth

Colors of Earth

When we think of our globe from a distance, we generally visualize two colors: blue and green. Water and land. Mostly water, consequently, our planet’s nickname of the blue marble.

Traveling around the globe every 90 minutes covering millions of miles with a focused lens on our beautiful planet from 250 miles above, I’ve captured many beautiful colors beyond blue and green that showcase Earth in new and interesting ways. Some colors are indicative of nature like desert sands and weather like snow. Other colors tell stories of Earth’s climate in bright splashes of yellows and greens of pollen and muted grey tones and clouded filters of pollution.

Blue and green still remain vivid and beautiful colors on Earth from the vantage point of the International Space Station, but here are some other colors that have caught my eye from my orbital perspective.

During A Recent Close Flyby Of The Gas Giant Jupiter, Our Juno Spacecraft Captured This Stunning Series

During a recent close flyby of the gas giant Jupiter, our Juno spacecraft captured this stunning series of images showing swirling cloud patterns on the planet’s south pole. At first glance, the series might appear to be the same image repeated. But closer inspection reveals slight changes, which are most easily noticed by comparing the far-left image with the far-right image.

Directly, the images show Jupiter. But, through slight variations in the images, they indirectly capture the motion of the Juno spacecraft itself, once again swinging around a giant planet hundreds of millions of miles from Earth.

Juno captured this color-enhanced time-lapse sequence of images on Feb. 7 between 10:21 a.m. and 11:01 a.m. EST. At the time, the spacecraft was between 85,292 to 124,856 miles (137,264 to 200,937 kilometers) from the tops of the clouds of the planet with the images centered on latitudes from 84.1 to 75.5 degrees south.

Make Sure You Observe the Moon on October 20

On Saturday, October 20, NASA will host the ninth annual International Observe the Moon Night. One day each year, everyone on Earth is invited to observe and learn about the Moon together, and to celebrate the cultural and personal connections we all have with our nearest celestial neighbor.

There are a number of ways to celebrate. You can attend an event, host your own, or just look up! Here are 10 of our favorite ways to observe the Moon:

1. Look up

The simplest way to observe the Moon is simply to look up. The Moon is the brightest object in our night sky, the second brightest in our daytime sky and can be seen from all around the world — from the remote and dark Atacama Desert in Chile to the brightly lit streets of Tokyo. On October 20, the near side of the Moon, or the side facing Earth, will be about 80 percent illuminated, rising in the early evening.

See the Moon phase on October 20 or any other day of the year!

2. Peer through a telescope or binoculars

With some magnification help, you will be able to focus in on specific features on the Moon, like the Sea of Tranquility or the bright Copernicus Crater. Download our Moon maps for some guided observing on Saturday.

3. Photograph the Moon

image

Our Lunar Reconnaissance Orbiter (LRO) has taken more than 20 million images of the Moon, mapping it in stunning detail. You can see featured, captioned images on LRO’s camera website, like the one of Montes Carpatus seen here. And, of course, you can take your own photos from Earth. Check out our tips on photographing the Moon!

4. Take a virtual field trip

Plan a lunar hike with Moontrek. Moontrek is an interactive Moon map made using NASA data from our lunar spacecraft. Fly anywhere you’d like on the Moon, calculate the distance or the elevation of a mountain to plan your lunar hike, or layer attributes of the lunar surface and temperature. If you have a virtual reality headset, you can experience Moontrek in 3D.

5. Touch the topography

Observe the Moon through touch! If you have access to a 3D printer, you can peruse our library of 3D models and lunar landscapes. This model of the Apollo 11 landing site created by NASA scientist Jacob Richardson, is derived from LRO’s topographic data. Near the center, you can actually feel a tiny dot where astronauts Neil Armstrong and Buzz Aldrin left the Lunar Descent Module.

6. Make Moon art

image

There are many movies that feature our nearest neighbor, from A Voyage to the Moon by George Melies, to Apollo 13, to the newly released First Man. You can also spend your evening with our lunar playlist on YouTube or this video gallery, learning about the Moon’s role in eclipses, looking at the Moon phases from the far side, and seeing the latest science portrayed in super high resolution. You’ll impress all of your friends with your knowledge of supermoons.

8. Listen to the Moon

Video credit: NASA’s Scientific Visualization Studio/Ernie Wright

Make a playlist of Moon songs. For inspiration, check out this list of lunar tunes. We also recommend LRO’s official music video, The Moon and More, featuring Javier Colon, season 1 winner of NBC’s “The Voice.” Or you can just watch this video featuring “Clair de Lune,” by French composer Claude Debussy, over and over.

9. See the Moon through the eyes of a spacecraft

image

Visible light is just one tool that we use to explore our universe. Our spacecraft contain many different types of instruments to analyze the Moon’s composition and environment. Review the Moon’s gravity field with data from the GRAIL spacecraft or decipher the maze of this slope map from the laser altimeter onboard LRO. This collection from LRO features images of the Moon’s temperature and topography. You can learn more about our different missions to explore the Moon here.

10. Continue your observations throughout the year

An important part of observing the Moon is to see how it changes over time. International Observe the Moon Night is the perfect time to start a Moon journal. See how the shape of the Moon changes over the course of a month, and keep track of where and what time it rises and sets. Observe the Moon all year long with these tools and techniques!

However you choose to celebrate International Observe the Moon Night, we want to hear about it! Register your participation and share your experiences on social media with #ObserveTheMoon or on our Facebook page. Happy observing!

6th grade South Lamar student, Alexis S., asked, " How old are you & how many hours a day do you train to be ready for space?"

I am 46 years old, but I don’t feel like I’m 46 because I have the best job in the world. I train everyday at least 8 hours, and even on the weekends I’m constantly thinking about work.

Get Space-Crafty with Earth Science!

It’s time to get space-crafty! (Get it?) We’re getting ready to launch Landsat 9 into space this fall, and we want to know, how does Landsat inspire you?

For nearly 50 years, Landsat satellites have been collecting important data and taking beautiful images of Earth, as a partnership between NASA and the U.S. Geological Survey. Scientists and policy makers alike use this data to understand climate change, deforestation, the growth of cities, and so much more.

Get Space-Crafty With Earth Science!

In celebration of the Landsat 9 launch in September, we are calling all crafters to create space-crafts inspired by your favorite Landsat image! From watercolor paintings to needlework to frosted cakes, let your creativity flow and show us how you see Landsat images.

Post a picture of your craft on Instagram, Twitter or Facebook with the hashtag #LandsatCraft. We will spotlight some on social media!

For a little inspiration, here are some #LandsatCraft examples from some of the people who work with Landsat:

Get Space-Crafty With Earth Science!

“Looking through the Visible Earth Landsat gallery for inspiration, I saw the Landsat Image Mosaic of Antarctica (LIMA) and knew immediately what I had to do -- recreate it in a mosaic of my own. LIMA is a composite of more than 1,000 cloud-free Landsat 7 images of Antarctica, and when it was released in 2007 it was our first high resolution, true-color look at the icy continent.” – Kate Ramsayer, NASA Landsat Communications Coordinator

Get Space-Crafty With Earth Science!

“I love embroidering satellite imagery and NASA data. For Landsat, I wanted something with lots of straight lines -- much easier to stitch! -- and crop fields like these fit the bill. It’s amazing how clearly we can see the influence of human activities in satellite imagery like this. It’s a constant reminder of the effect we have on our home planet.” – Katy Mersmann, Earth Science Social Media Lead

Get Space-Crafty With Earth Science!

“We didn’t have the discipline or the organizational skills to do any of the really, really fancy images, like Lena Delta, so we chose Garden City, Kansas in 1972. We added a model of Landsat 1, too.” – Ryan Fitzgibbons, Earth Science Producer, and Charles Fitzgibbons, Age 8

Get Space-Crafty With Earth Science!

"I was inspired by this Landsat image which demonstrates how we can use satellite imagery to remotely monitor cover crop performance, a sustainable farming practice that promotes soil health. Since I began working with NASA Harvest, NASA's Food Security and Agriculture Program, I've come to understand the critical importance of conservation agriculture and resilient farmlands in support of a food secure future for all, especially in the face of a changing climate." – Mary Mitkish, NASA Harvest Communications Lead

Get Space-Crafty With Earth Science!

“I chose particular ingredients that represent the Landsat qualities that we celebrate:

The base spirit is gin because Landsat data is clean and precise. Vermouth represents our foreign collaborators. Using both lemon and lime juices signifies the diverse uses of the data. The ginger is for the land we study. The apple, well, because it’s American. The club soda makes it a long drink, for the long data record.” – Matthew Radcliff, NASA Landsat Producer

Get Space-Crafty With Earth Science!

“Last year for the 50th Earth Day, I created this poster, inspired by our views of river deltas -- many captured by Landsat satellites -- which are particularly beautiful and evocative of water coursing through our land like a circulation system of nature. In 2000, Landsat 7 took one of my favorite images of the Lena Delta, which is the basis for this art.” – Jenny Mottar, Art Director for NASA Science

Are you feeling inspired to create yet? We’re so excited to see your #LandsatCraft projects! Follow NASA Earth on Twitter, Facebook, and Instagram to see if your art is shared!

Kill the lights – We’re Simulating a Moonwalk!

At the bottom of a very dark swimming pool, divers are getting ready for missions to the Moon. Take a look at this a recent test in the Neutral Buoyancy Laboratory at NASA’s Johnson Space Center. NASA astronauts are no strangers to extreme environments. We best prepare our astronauts by exposing them to training environments here on Earth that simulate the 1/6th gravity, suit mobility, lighting and lunar terrain they'll expect to see on a mission to the Moon. Practice makes perfect.

Kill The Lights – We’re Simulating A Moonwalk!

The Neutral Buoyancy Laboratory at NASA's Johnson Space Center is where astronauts train for spacewalks, and soon, moonwalks.

When astronauts go to the Moon’s South Pole through NASA’s Artemis program, the Sun will only be a few degrees over the horizon, creating long, dark shadows. To recreate this environment, divers at the lab turned off the lights, put up black curtains on the pool walls to minimize reflection, and used powerful underwater lamps to simulate the environment astronauts might experience on lunar missions.

Kill The Lights – We’re Simulating A Moonwalk!

These conditions replicate the dark, long shadows astronauts could see and lets them evaluate the different lighting configurations. The sand at the bottom is common pool filter sand with some other specialized combinations in the mix.

Kill The Lights – We’re Simulating A Moonwalk!

This was a test with divers in SCUBA gear to get the lighting conditions right, but soon, NASA plans to conduct tests in this low-light environment using spacesuits.

Kill The Lights – We’re Simulating A Moonwalk!

Neutral buoyancy is the equal tendency of an object to sink or float. Through a combination of weights and flotation devices, an item is made to be neutrally buoyant and it will seem to "hover" under water. In such a state, even a heavy object can be easily manipulated, much as it is in the zero gravity of space, but will still be affected by factors such as water drag.

The Neutral Buoyancy Laboratory is 202 ft in length, 102 ft in width and 40 ft in depth (20 ft above ground level and 20 ft below) and holds 6.2 million gallons of water.

Help Explore Your Own Solar Neighborhood

We’re always making amazing discoveries about the farthest reaches of our universe, but there’s also plenty of unexplored territory much closer to home.

image

Our “Backyard Worlds: Planet 9” is a citizen science project that asks curious people like you — yes, you there! — to help us spot objects in the area around our own solar system like brown dwarfs. You could even help us figure out if our solar system hosts a mysterious Planet 9!

image

In 2009, we launched the Wide-field Infrared Survey Explorer (WISE). Infrared radiation is a form of light that humans can’t see, but WISE could. It scans the sky for infrared light, looking for galaxies, stars and asteroids. Later on, scientists started using it to search for near-Earth objects (NEOWISE) like comets and asteroids.

image

These searches have already turned up so much data that researchers have trouble hunting through all of it. They can’t do it on their own. That’s why we asked everyone to chip in. If you join Backyard Worlds: Planet 9, you’ll learn how to look at noisy images of space and spot previously unidentified objects. 

You’ll figure out how to tell the difference between real objects, like planets and stars, and artifacts. Artifacts are blurry blobs of light that got scattered around in WISE’s instruments while it was looking at the sky. These “optical ghosts” sometimes look like real objects.

image

Why can’t we use computers to do this, you ask? Well, computers are good at lots of things, like crunching numbers. But when it comes to recognizing when something’s a ghostly artifact and when it’s a real object, humans beat software all the time. After some practice, you’ll be able to recognize which objects are real and which aren’t just by watching them move!

image

One of the things our citizen scientists look for are brown dwarfs, which are balls of gas too big to be planets and too small to be stars. These objects are some of our nearest neighbors, and scientists think there’s probably a bunch of them floating around nearby, we just haven’t been able to find all of them yet. 

But since Backyard Worlds launched on February 15, 2016, our volunteers have spotted 432 candidate brown dwarfs. We’ve been able to follow up 20 of these with ground-based telescopes so far, and 17 have turned out to be real!

image

Image Credit: Ryan Trainor, Franklin and Marshall College

How do we know for sure that we’ve spotted actual, bona fide, authentic brown dwarfs? Well, like with any discovery in science, we followed up with more observation. Our team gets time on ground-based observatories like the InfraRed Telescope Facility in Hawaii, the Magellan Telescope in Chile (pictured above) and the Apache Point Observatory in New Mexico and takes a closer look at our candidates. And sure enough, our participants found 17 brown dwarfs!

image

But we’re not done! There’s still lots of data to go through. In particular, we want your help looking for a potential addition to our solar system’s census: Planet 9. Some scientists think it’s circling somewhere out there past Pluto. No one has seen anything yet, but it could be you! Or drop by and contribute to our other citizen science projects like Disk Detective.

Congratulations to the citizen scientists who spotted these 17 brown dwarfs: Dan Caselden, Rosa Castro, Guillaume Colin, Sam Deen, Bob Fletcher, Sam Goodman, Les Hamlet, Khasan Mokaev, Jörg Schümann and Tamara Stajic.

A Laboratory for Star Formation

Alt text: In this image of NGC 3603, a bright cluster of stars shining in red, orange, and yellow hues dominates the center. The stars become more sporadic throughout the rest of the image, glittering against a black backdrop of space and nebulous indigo clouds that glow in the picture’s lower half.

Location: In the Carina spiral arm of our Milky Way Galaxy

Distance from Earth: About 20,000 light-years

Object type: Nebula and open star cluster

Discovered by: Sir John Herschel in 1834

Imaged here by the Hubble Space Telescope, NGC 3603 is a collection of thousands of large, hot stars, including some of the most massive stars known to us. Scientists categorize it as an “open cluster” because of its spread-out shape and low density of stars. Surrounding the bright star cluster are plumes of interstellar gas and dust, which comprise the nebula part of this cosmic object. New stars are formed from the gaseous material within these clouds! NGC 3603 holds stars at a variety of life stages, making it a laboratory for scientists to study star evolution and formation. Astronomers estimate that star formation in and around the cluster has been occurring for 10 to 20 million years.

Read more information about NGC 3603 here.

Right now, the Hubble Space Telescope is delving into its #StarrySights campaign! Find more star cluster content and breathtaking new images by following along on Hubble’s Twitter, Facebook, and Instagram.
