On Nov. 7, our Solar Dynamics Observatory (SDO) satellite saw a lunar transit when the Moon passed between SDO and the Sun. At its peak, the Sun was about 44 percent covered, and the transit lasted just under an hour.

Such lunar transits provide scientific value: The sharp edge of the lunar limb helps researchers measure how light diffracts around the telescope's optics and filter support grids, allowing scientists to better calibrate the instruments for even sharper images.

This image was captured in a wavelength of #extreme #ultraviolet light, a type of light that is typically invisible to our eyes but is colorized here in gold.

This image is an artist's concept of a blue supergiant star that once existed inside a cluster of young stars in the spiral galaxy NGC 3938, located 65 million light-years away. The star may have been as massive as 50 suns and burned at a furious rate, making it hotter and bluer than our Sun. When it exploded in 2017, astronomers categorized it as a Type Ic supernova because of the lack of hydrogen and helium in the supernova's spectrum. Progenitor stars to Type Ic supernovas have been hard to find. But astronomers sifting through @NASAHubble archival images may have uncovered the star that detonated as supernova 2017ein.

This video clip was compiled from images taken by NASA's EPOXI mission spacecraft during its flyby of comet Hartley 2 on Nov. 4, 2010. During the encounter, the spacecraft and comet whisked past each other at a speed of 12.3 kilometers per second (27,560 miles per hour). The spacecraft came within about 700 kilometers (435 miles) of the comet's nucleus at the time of closest approach.

Massive Antarctic Iceberg Spotted on NASA IceBridge Flight

NASA’s Operation IceBridge on Wednesday, November 7, flew over an iceberg that is three times the size of Manhattan. This was the first time anyone has laid eyes on the giant iceberg, dubbed B-46 by the U.S. National Ice Center, that broke off from Pine Island Glacier in late October.

On October 29, the National Ice Center, which tracks icebergs for navigation purposes, estimated the surface area of B-46 at 66 square nautical miles, though satellite imagery and the IceBridge flight showed that the main iceberg is already beginning to break up.

Ice shelves, floating glacial ice areas that surround much of Antarctica, calve icebergs as part of the natural process of ice flowing out to sea. But scientists are also watching closely to see if the frequency of calving events is changing over time. In late 2016, IceBridge saw a crack beginning across the ~ approximately 22 mile-wide trunk of Pine Island Glacier. It took a year for the rift to fully form and the iceberg named B-44 to break away in September 2017. The crack that would become B-46 was first noticed in late September 2018 and the iceberg broke away about a month later. Pine Island has now calved major icebergs in 2013, 2015, 2017, and 2018. Prior to that stretch, the glacier was experiencing major calving events about every six years.

Pine Island and nearby Thwaites Glacier alone are contributing about 1 millimeter per decade to global sea level rise, as their flow of ice to the sea has accelerated in recent years, according to NASA research.

A new NASA laser instrument set to launch to the International Space Station in December will help scientists create the first three-dimensional map of the world’s temperate and tropical forests. The Global Ecosystem Dynamics Investigation, or GEDI, is scheduled to launch on SpaceX’s Falcon 9 rocket. From the station, GEDI’s advanced laser technology will reveal the three-dimensional structure of forest ecosystems around the globe.

From its perch on the exterior of the orbiting laboratory, GEDI will be the first space-borne laser instrument to measure the structure of Earth's tropical and temperate forests in high resolution and three dimensions. These measurements will help fill in critical gaps in scientists' understanding of how much carbon is stored in the world's forests, the potential for ecosystems to absorb rising concentrations of carbon dioxide in Earth's atmosphere, and the impact of forest changes on biodiversity.

GEDI will accomplish its science goals through an ingenious use of light. The instrument is a lidar, which stands for light detection and ranging. It captures information by sending out laser pulses and then precisely measuring the light that is reflected back.

Camp Fire Rages in California

On the morning of November 8, 2018, the Camp Fire erupted 90 miles (140 kilometers) north of Sacramento, California. By evening, the fast-moving fire had charred around 18,000 acres and remained zero percent contained, according to news reports.

The Operational Land Imager on Landsat 8 acquired this image on November 8, 2018, around 10:45 a.m. local time (06:45 Universal Time). The natural-color image was created using bands 4-3-2, along with shortwave infrared light to highlight the active fire.

Officials are evacuating several towns, including Paradise. They have also closed several major highways.

NASA Goddard Hosts Young Women for STEM Girls Night In

Late Friday night, 40 high school girls arrived at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for a STEM-themed sleepover, ready to learn about careers in science, technology, engineering and math. The educational event offered young women a chance to meet working female scientists and to discover opportunities for women in STEM-related professions.

This "super-resolution” view of asteroid Bennu was created using eight images obtained by NASA’s @osiris_rex spacecraft on Oct. 29, 2018, from a distance of about 205 miles (330 km). The spacecraft was moving as it captured the images with the PolyCam camera, and Bennu rotated 1.2 degrees during the nearly one minute that elapsed between the first and the last snapshot. The team used a super-resolution algorithm to combine the eight images and produce a higher resolution view of the asteroid. Bennu occupies about 100 pixels and is oriented with its north pole at the top of the image.

OSIRIS-REx seeks answers to the questions that are central to the human experience: Where did we come from? What is our destiny? Asteroids, the leftover debris from the solar system formation process, can answer these questions and teach us about the history of the Sun and planets.

The OSIRIS-REx spacecraft is traveling to Bennu, a carbonaceous asteroid whose material may record the earliest history of our solar system. Bennu may contain the molecular precursors to the origin of life and the Earth’s oceans. Bennu is also one of the most potentially hazardous asteroids, as it has a relatively high probability of impacting Earth late in the 22nd century. OSIRIS-REx will determine Bennu’s physical and chemical properties, which will be critical to know in the event of an impact mitigation mission. Finally, asteroids like Bennu contain natural resources such as water, organics and precious metals. In the future, these asteroids may one day fuel the exploration of the solar system by robotic and manned spacecraft.

Hubble Finds Smiling Face in a Hunt for Newborn Stars

This image, taken with the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3), shows a patch of space filled with galaxies of all shapes, colors and sizes, many of which belong to the galaxy cluster SDSS J0952+3434.

Just below center is a formation of galaxies akin to a smiling face. Two yellow-hued blobs hang atop a sweeping arc of light. The lower, arc-shaped galaxy has the characteristic shape of a galaxy that has been gravitationally lensed — its light has passed near a massive object en route to us, causing it to become distorted and stretched out of shape.

Hubble captured this image in an effort to understand how new stars spring to life throughout the cosmos. WFC3 is able to view distant galaxies at an unprecedented resolution — high enough to locate and study regions of star formation within them.

Stars are born within giant clouds of gas. These massive clouds, or stellar nurseries, grow unstable and begin to collapse under gravity, becoming the seeds that will grow into new stars. By analyzing the luminosity, size and formation rate of different stellar nurseries, scientists hope to learn more about the processes that can lead to the formation of a newborn star. Studying nurseries within different galaxies will provide information about star formation at different points in time and space throughout the universe.
