What Is the James Webb Space Telescope? | NASA Space Place – NASA Science for Kids
The mirrors fold up inside the rocket, then unfold to form one large mirror in orbit.
Why are the mirrors gold? A thin layer of gold helps the mirrors reflect infrared light!

It will be hunting for signs of life on other planets.

Could life survive on this faraway planet? Astronomers study the light from stars and planets to see if they might have the ingredients for life. Animation credit: NASA/ESA/Dani Player (STScI), Music credit: Steve Combs
Our solar system isn’t the only home for planets! Scientists have discovered thousands of planets orbiting stars other than our Sun. These are called exoplanets. The James Webb Space Telescope will help to study the atmospheres of exoplanets. Could the atmospheres of some exoplanets hold the building blocks for life? We will find out soon!

What is the James Webb Space Telescope doing right now?
The James Webb Space Telescope launched on December 25, 2021. Want to stay up to date and learn more about NASA’s biggest and most powerful telescope? Check out this cool timeline to learn what the telescope is doing right now! Also, Find more facts, photos, videos and more at the James Webb Space Telescope Website!

Cloudy With a Chance of Eclipse
“Total solar eclipses are rare enough that the observational record of clouds and eclipses is still sparse,” said Marilé Colón Robles, the project scientist for GLOBE Clouds. “There are still plenty of unanswered questions about clouds and total solar eclipses.”
Among them: How does the magnitude of the brief temperature decline vary depending on cloud conditions? And to what extent, if any, might the eclipse contribute to changes in convective clouds that are observable from the ground or with satellites? “The relatively large and abrupt perturbation of the atmosphere during an eclipse can be used to test and improve our theoretical understanding and numerical simulations of atmospheric processes, things key to weather forecasting and other types of atmospheric modeling,” added Colón Robles. “The eclipse offered a perfect ‘natural experiment’ to do that.”

April 8, 2024

One easy way citizen scientists collected data to help the scientific community answer these questions was via smartphones. For about a month prior to the eclipse, the GLOBE team encouraged their network of observers to download their app and collect observations of clouds leading up to and on eclipse day. When the day finally arrived, more than 7,000 citizen scientists—including students and teachers—collected photos of cloud conditions before, during, and after the eclipse. Many people also used thermometers to measure air temperatures, following protocols developed by the GLOBE team.

The image at the top of the page highlights the variety in the clouds that the ABI (Advanced Baseline Imager) on the GOES-16 (Geostationary Operational Environmental Satellite-16) satellite observed at 18:40 Universal Time, about 1 hour before the Moon’s shadow passed over the region.

The set of photos above were collected by Colón Robles near Mentor, Ohio, at 18:39 UTC. Many images like these submitted through the GLOBE Observer app were automatically paired with satellite images acquired at roughly the same time. With photos taken in multiple directions and looking straight overhead, it is easier to match cloud features in photos taken on the ground with clouds features in corresponding satellite images.

 The Universe of Very Cold: The James Webb Space Telescope, MIRI, and the Cryocooler
 
 The James Webb Space Telescope (JWST) takes incredible images using infrared light. The optics and science instruments must be incredibly cold, especially JWST’s Mid-Infrared Instrument (MIRI), which needs to be at a temperature of less than 7 kelvins, or -447 F. This is not possible without the Cryocooler, which keeps MIRI’s detectors cool.

 InSight End of Mission: Our Time on Mars
 
 The InSight Mission to Mars began its journey to the red planet in May 2018. Upon its arrival in November of that year, InSight began an ambitious mission to reveal the internal structure of Mars. The lander detected over 1000 Mars seismic events, studied the Martian weather, and even found magnetic “ghosts” from an old electrical field. The mission ended 4 years after it began, when the solar panels finally succumbed to the dust deposition that prevented them from generating power.

Terra Views the Eclipse! (April 8)

Posted on April 5, 2024 by Nyssa Rayne 
	Posted in News and Events 

You may have heard about the upcoming full solar eclipse, happening this upcoming April 8th, 2024 — but did you know Terra will have one of the “best seats in the house” for viewing this rare celestial experience?!
In the United States, the center “totality” shadow of the eclipse will pass from south to north along a track on the East Coast from Texas to New York. But because of Terra’s unique morning orbit timing and scheduled location, the satellite’s wide view will capture the eclipse shadow in the early morning hours and over the ocean, limiting visible contrast but still recording important data to be later used in reconstructing this event. Check out the sections below for additional information and eclipse-viewing resources from NASA!

Step 1. Access the map of the area that you are interested in.

Launch the CoCoRaHS website
Once the site has loaded, click on the word, “maps”.

Once the daily maps page loads, select the “Station Number Maps” link from the list of map types. (last one in the list)
Under map location title, use the pull down menu to select “stations,” choose your state of interest. In this case, choose Indiana.
Next choose the “county,” Monroe. Leave the dates and map colors in their default settings.
Click the button, “Get Map”.

A map window will open with stations shown as little dots with their ID numbers next to them. We will use this station location map for reference later, so save it in the background or on your desktop.

Step 2. Acquire Precipitation data from CoCoRaHS

Open a new window in your browser with the CoCoRaHS home page again.
This time on the top tab bar, click on, “view data”.
A new page will load. On this page there will be a list of station types. Scroll most of the way down the list to the link “List Stations”. This is a list of stations by state and county. Click on this link.

On the next page, choose the state and county you are interested in. For this example choose, Indiana and Monroe County. click search. There are many stations in Indiana, this will select only the 15 stations that are in Monroe County. The stations are listed by; state, county and ID number. In the table of stations, under the “view” heading, click on the magnifying glass in the row with “IN-MN-14″ to learn more about this station’s detailed location, including its latitude and longitude.
Record this station’s latitude and longitude to use later in the comparison with satellite data. (Record the following: Station IN-MN-14, Latitude 39.265964, Longitude -86.521293.) Optional: click view the station in Google Maps.

FAQs • San Bruno, CA • CivicEngage
How many different devices can I use?

There's no limit to the number of devices you can use, however TV networks may limit the number you can use at the same time. Remember, it's important to keep your username and password confidential. Use of your credentials by others will result in the loss of your WTVE privileges. 

11.
Does WatchTVEverywhere count against my mobile data plan?

It might. Check your data plan before you use WatchTVEveryhwere on a smart phone or wireless network. WTVE programs transmit a lot of data. This can be expensive if you have a limited data plan. We have no way to know when you have exceeded your data plan's limits. You are responsible for all charges billed to you by your mobile carrier. 

12.
Where can I WatchTVEverywhere?

WTVE works anywhere you can receive an Internet signal: in your house, at work, at the mall, at a hotel, the airport, a vacation home- anywhere! Wired connections and in-home WiFi will provide the best overall quality. The quality of WatchTVEverywhere service while traveling (airports, stores, etc) will vary with the signal strength and bandwidth of the Internet connection you use. Be extra careful when traveling, especially outside the U.S. Data roaming charges may apply, and they can be very expensive. 

13.
How much does it cost?

Nothing! At this time, there's no extra cost for WatchTVEverywhere, so feel free to explore. There is nothing on the site that will result in an extra cost to you (except overage charges from your cellular carrier, if applicable). As long as you can receive the TV Network in your "regular" cable channel lineup, you may view that network's TV Everywhere content, if available.
