Multiwavelength Astronomy: The Big Picture (NASA)
Until the 20th century, astronomers learned virtually all they knew about sources in the sky from only the tiny fraction of electromagnetic radiation that is visible.
However, as astronomers have discovered how to collect radiation outside this part of the spectrum, they have been able to learn much more about the universe. Many objects reveal different aspects of their composition and behavior at different wavelengths. Other objects are utterly invisible at one wavelength, yet are visible at another.
In this video, Dr. Padi Boyd explains the exciting future of multiwavelength astronomy and how important Hubble is to exploring the mysteries of the universe.

How to Safely View an Annular Eclipse
On Oct. 14, 2023, an annular solar eclipse will cross North, Central, and South America. Visible in parts of the United States, Mexico, and many countries in South and Central America, millions of people in the Western Hemisphere can experience this eclipse.
Eclipses are a wonderful experience, but it’s important to carefully follow safety procedures. During an annular eclipse, there is no period of totality when the Moon completely blocks the Sun. Therefore, it is never safe to look directly at the annular eclipse without proper eye protection specially designed for solar viewing. Do not use standard binoculars or telescopes to watch a solar eclipse without safe solar filters attached to the front of the device. Regular sunglasses are NOT safe for attempting to look directly at the Sun.

NASA's Sun Study Unveils Astonishing Insights: 133 Days of Discovery
This video chronicles solar activity from Aug. 12 to Dec. 22, 2022, as captured by NASA’s Solar Dynamics Observatory (SDO). From its orbit in space around Earth, SDO has steadily imaged the Sun in 4K x 4K resolution for nearly 13 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 133-day time-lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme-ultraviolet wavelength that shows the Sun’s outermost atmospheric layer: the corona. Compiling images taken 108 seconds apart, the movie condenses 133 days, or about four months, of solar observations into 59 minutes. The video shows bright active regions passing across the face of the Sun as it rotates. The Sun rotates approximately once every 27 days. The loops extending above the bright regions are magnetic fields that have trapped hot, glowing plasma. These bright regions are also the source of solar flares, which appear as bright flashes as magnetic fields snap together in a process called magnetic reconnection. While SDO has kept an unblinking eye pointed toward the Sun, there have been a few moments it missed. Some of the dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. Other blackouts are caused by instrumentation being down or data errors. SDO transmits 1.4 terabytes of data to the ground every day. The images where the Sun is off-center were observed when SDO was calibrating its instruments. SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe.

Video Description: On the left side of the frame is the full circle of the Sun. It appears in a golden yellow color, but is splotchy and with thin yellow wisps extending from the surface. Some areas are very bright and others are almost black. The whole Sun rotates steadily, with one full rotation taking 12 minutes in this time-lapse. There are usually only a few bright regions visible at a time and they shift and flash like small fires. From these regions, there are wispy loops reaching up above the surface that rapidly change shape and size. On the right side of the frame are two white-outlined squares with enlargements of interesting regions of the Sun.

NASA discovered SWOT: Earth Science Satellite Will Help Communities Plan for a Better Future
A new Earth science mission, led by NASA and the French space agency Centre National d’Études Spatiales (CNES), will help communities plan for a better future by surveying the planet’s salt and freshwater bodies. The Surface Water and Ocean Topography (SWOT) mission will measure the height of water in lakes, rivers, reservoirs, and the oceans. As climate change accelerates the water cycle, more communities around the world will be inundated with water while others won’t have enough. SWOT data will be used to improve flood forecasts and monitor drought conditions, providing essential information to water management agencies, civil engineers, universities, the U.S. Department of Defense, disaster preparedness agencies, and others who need to track water in their local areas. In this video, examples of how SWOT data will be used in these communities are shared by a National Weather Service representative in Oregon, an Alaska Department of Transportation engineer, researchers from the University of Oregon and University of North Carolina, a NASA Jet Propulsion Laboratory scientist working with the Department of Defense, and a JPL scientist working with the Louisiana Coastal Protection and Restoration Agency. :30 - Flood Watches & Warnings - Portland, Oregon 1:08 - Water Management - Fern Ridge Lake, Oregon 2:05 - Protecting Infrastructure - Alaska 2:54 - National Security - Department of Defense 3:24 - Coastal Protection - Mississippi River Delta SWOT is expected to launch from Vandenberg Space Force Base in California in December 2022. The mission is a collaboration between NASA and CNES, with contributions from the Canadian Space Agency and UK Space Agency. JPL, which is managed for NASA by Caltech in Pasadena, California, leads the U.S. component of the project.
