Thank you for joining us as we shared #BlackHoleFriday images & information about black holes. We'll keep hunting for black holes and studying them.
How? Spotting black holes is tricky. Because they don’t give off light, astronomers have a difficult time pinpointing their location. But when a black hole gets close enough to an object, like a star, for example, and begins consuming the object's mass, the matter that pours into its gravitational clutches can get so hot that it glows and releases energy in the form of X-ray light. The most powerful X-rays are emitted from the hottest material swirling just outside the edge of the black hole. By observing this light with space telescopes, scientists can determine where black holes are hiding in the cosmos.

Colorful Liquid in Space (Part 1): Astronauts (@StationCDRKelly) on the International Space Station (@ISS) dissolved an effervescent tablet in a floating ball of water, and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station. This footage is one of the first of its kind. The cameras are being evaluated for capturing science data and vehicle operations by our engineers.
Brightening Magnetic Loops: Two active regions sprouted arches of bundled magnetic loops in this video from Our Solar Dynamics Observatory taken on Nov. 11-12, 2015. Charged particles spin along the magnetic field, tracing out bright lines as they emit light in extreme ultraviolet wavelengths. About halfway through the video, a small eruption from the active region near the center causes the coils to rise up and become brighter as the region re-organizes its magnetic field. This video was taken in extreme ultraviolet wavelengths of 171 angstroms, typically invisible to our eyes but colored here in gold.
New imagery from our Hubble Space Telescope is revealing details never before seen on Jupiter. High-resolution maps and spinning globes are the first products to come from a program to study the solar system's outer planets each year using Hubble. The observations are designed to capture a broad range of features, including winds, clouds, storms and atmospheric chemistry. These annual studies will help current and future scientists see how such giant worlds change over time. Already, the Jupiter images have revealed a rare wave just north of the planet's equator and a unique filamentary feature in the core of the Great Red Spot not seen previously.
The latest images (as of Sept. 11, 2015) downloaded from NASA's New Horizons spacecraft were stitched together and rendered on a sphere to make this flyover. This animation, made with the LORRI (Long Range Reconnaissance Imager) images, begins with a low-altitude look at the informally named Norgay Montes, flies northward over the boundary between informally named Sputnik Planum and Cthulhu Regio, turns, and drifts slowly east. During the animation, the altitude of the observer rises until it is about 10 times higher to show about 80% of the hemisphere New Horizons flew closest to on July 14, 2015.

A small, but complex mass of solar material gyrated and spun about over the course of 40 hours above the surface of the sun on Sept. 1-3, 2015. It was stretched and pulled back and forth by powerful magnetic forces in this sequence captured by our Solar Dynamics Observatory, or SDO. The temperature of the ionized iron particles observed in this extreme ultraviolet wavelength of light was about 5 million degrees Fahrenheit. SDO captures imagery in many wavelengths, each of which represents different temperatures of material, and each of which highlights different events on the sun. Each wavelength is typically colorized in a pre-assigned color. Wavelengths of 335 Angstroms, such as are represented in this picture, are colorized in blue.

Summer Vacation: NASA astronaut Scott Kelly and his Russian crewmates Gennady Padalka and Mikhail (Misha) Kornienko took a road trip of sorts from the International Space Station after a little more than five months of their stay. They left their orbital home for a 20-minute get away to move their spacecraft. They undocked their Soyuz that brought them to the space station back in late March from one International Space Station module to another, clearing a module for the arrival of a new crew. It's the first time in nearly two years since nine crew members are aboard the station simultaneously. It's a full house.

We are explorers. Our vision is to reach for new heights and reveal the unknown so that what we do and learn will benefit all humankind. And for over 25 years, our Hubble Space Telescope has been revealing the unknown cosmos. Hubble is peering into the farthest reaches of the universe and back to its earliest moments of existence, helping us understand the universe's origin, evolution and destiny. Hubble continues to explore as we develop its successor, the James Webb Space Telescope, which will capture light from the universe's earliest stars.
NASA Astronaut Scott Kelly shared this incredible video last night, August 11, showing “our galactic home” with the stars of the Milky Way. Kelly is living and working off the Earth, for the Earth aboard the station for a yearlong mission. Traveling the world more than 220 miles above the Earth, and at 17,500 mph, he circumnavigates the globe more than a dozen times a day conducting research about how the body adapts and changes to living in space for a long duration.
Look closely & don't miss it! The International Space Station, with a crew of six onboard, is seen in silhouette as it transits the moon at roughly five miles per second, Sunday, Aug. 2, 2015, Woodford, VA. Onboard are: NASA astronauts Scott Kelly and Kjell Lindgren: Russian Cosmonauts Gennady Padalka, Mikhail Kornienko, Oleg Kononenko, and Japanese astronaut Kimiya Yui.
Using NASA's Spitzer Space Telescope, astronomers have confirmed the discovery of the nearest rocky planet outside our solar system, larger than Earth and a potential gold mine of science data.
Dubbed HD 219134b, this exoplanet, which orbits too close to its star to sustain life, is a mere 21 light-years away. While the planet itself can't be seen directly, even by telescopes, the star it orbits is visible to the naked eye in dark skies in the Cassiopeia constellation, near the North Star. HD 219134b is also the closest exoplanet to Earth to be detected transiting, or crossing in front of, its star and, therefore, perfect for extensive research.
This artist's concept video shows the silhouette of the rocky planet crossing, or transiting, its star.
We dropped a Cessna 172 from 100 feet today. With a thunderous rattle, the aircraft plowed into the soil as its windshield shattered, its wings wrenched off and its fuselage flipped -- tail over nose -- onto its back. Researchers were pleased. The controlled experiment that will help us improve aviation emergency response times. We’re developing next-gen search and rescue technology as part of an international effort involving members from 43 countries and organizations.
Animated Flyover of Pluto’s Icy Mountain and Plains: This simulated flyover of Pluto’s Norgay Montes (Norgay Mountains) and Sputnik Planum (Sputnik Plain) was created from New Horizons closest-approach images. Norgay Montes have been informally named for Tenzing Norgay, one of the first two humans to reach the summit of Mount Everest. Sputnik Planum is informally named for Earth’s first artificial satellite. The images were acquired by the Long Range Reconnaissance Imager (LORRI) on July 14 from a distance of 48,000 miles (77,000 kilometers). Features as small as a half-mile (1 kilometer) across are visible.

You ain't seen nothing yet! Today's image was just the latest in a series of the New Horizons Pluto "picture show." Tomorrow, more images of surface close-ups will make the more than four-hour journey to Earth at the speed of light to give ten times the resolution of what we saw today, with details as small as New York's Central Park. Stay tuned!
Come Fly with New Horizons on its Approach to Pluto: Images from New Horizons show the view from aboard the spacecraft closes in on the Pluto system for a July 14 flyby. This time-lapse approach movie was made from images from the Long Range Reconnaissance Imager (LORRI) camera aboard New Horizons spacecraft taken between May 28 and June 25, 2015. During that time the spacecraft distance to Pluto decreased almost threefold, from about 35 million miles to 14 million miles (56 million kilometers to 22 million kilometers). The images show Pluto and its largest moon, Charon, growing in apparent size as New Horizons closes in. As it rotates, Pluto displays a strongly contrasting surface dominated by a bright northern hemisphere, with a discontinuous band of darker material running along the equator. Charon has a dark polar region, and there are indications of brightness variations at lower latitudes.
