Black Hole Eats Star, Beams Signal to Earth
On March 28, 2011, NASA's Swift detected intense X-ray flares thought to be caused by a black hole devouring a star. In one model, illustrated here, a sun-like star on an eccentric orbit plunges too close to its galaxy's central black hole. About half of the star's mass feeds an accretion disk around the black hole, which in turn powers a particle jet that beams radiation toward Earth

00:00:17
Boiling Fluids Behave Quite Differently in Space
The boiling process is really different in space, since the vapor phase of a boiling liquid does not rise via buoyancy. Spacecraft and Earth-based systems use boiling to efficiently remove large amounts of heat by generating vapor from liquid. For example, many power plants use this process to generate electricity. An upper limit, called the critical heat flux, exists where the heater is covered with so much vapor that liquid supply to the heater begins to decrease. The goal of BXF-MABE is to determine the critical heat flux during boiling in microgravity. This will facilitate the optimal design of cooling systems on Earth, as well as in space exploration vehicles.

Chandra Captures Neutron Star Action
This movie from NASA's Chandra X-ray Observatory shows a fast moving jet of particles produced by a rapidly rotating neutron star, and may provide new insight into the nature of some of the densest matter in the universe. The star of this movie is the Vela pulsar, a neutron star that was formed when a massive star collapsed. The Vela pulsar is about 1,000 light years from Earth, spansis about 12 miles in diameter, and makes over 11 complete rotations every second, faster than a helicopter rotor. As the pulsar whips around, it spews out a jet of charged particles that race out along the pulsar’s rotation axis at about 70% of the speed of light. In this still image from the movie, the location of the pulsar and the 0.7-light-year-long jet are labeled. The Chandra data shown in the movie, containing 8 images obtained between June and September 2010, suggest that the pulsar may be slowly wobbling, or precessing, as it spins. The shape and the motion of the Vela jet look strikingly like a ...

Introduction to Heliophysics
This short overview for NASA's Heliophysics division explains how NASA studies the sun -- and more importantly, how it affects our daily lives.

00:01:23
Intro to Space Weather Vocabulary
Heliophysics research studies how energy and material from the sun affects Earth and the entire solar system. It’s a complex system that begins on the sun when events on the sun, such as solar flares or coronal mass ejections, travel out into space. These cause electromagnetic effects that drive space weather close to Earth -- from aurora to radio blackouts to changes in the radiation belts surrounding Earth. Scientists study the minutiae of how energy transfers from one event to the other and which electromagnetic waves create which conditions near Earth. Since space weather effects can disrupt satellites in space, scientists need to understand the system in even more detail. Watch the video to see how events on the sun affect Earth. Suitable for all ages, this intro to space weather covers vocabulary like coronal mass ejection (CME), solar wind, and solar flare. It also outlines potential effects of solar storms on our planet.

Landsat- 25 Years in the Pacific Northwest Forest -- North South Tour
This visualization shows a sequence of Landsat-based data in the Pacific Northwest. There is one data set for each year representing an aggregate of the approximate peak of the growing season (around August). The data was created using a sophisticated algorithm called LandTrendr. LandTrendr analyzes 'stacks' of Landsat scenes, looking for statistical trends in the data and filtering out noise. The algorithm evaluated data from more than 1,800 Landsat Thematic Mapper images, nearly 1 Terabyte of raw imagery, to define the life histories of each of more than 336 million pixels on the landscape. The resulting trends identify periods of stability and change that are displayed as colors. In these false color images, the colors represent types of land; for example, blue areas are forests; orange/yellow areas are agriculture; and, purple areas are urban. Each 'stack' is representative of a Landsat scene. There are 22 stacks stitched together to cover most of the U.S. Pacific Northwest.

Measuring Ripples in Space-Time
Einstein predicted gravity waves in his general theory of relativity, but to date these ripples in the fabric of space-time have never been observed. Now a scientific research technique called Atomic Interferometry is trying to re-write the canon. In conjunction with researchers at Stanford University, scientists at NASA Goddard are developing a system to measure the faint gravitational vibrations generated by movement of massive objects in the universe. The scientific payoff could be important, helping better clarify key issues in our understanding of cosmology. But application payoff could be substantial, too, with the potential to develop profound advances in fields like geolocation and timekeeping. In this video we examine how the system would work, and the scientific underpinnings of the research effort.

NASA's Kepler Mission Discovers Multiple Planets Orbiting Twin Suns
NASA's Kepler mission has discovered the first transiting circumbinary system -- multiple planets orbiting two suns -- 4,900 light-years from Earth, in the constellation Cygnus, proving that more than one planets can form and survive in orbit around a binary star. The inner planet, Kepler-47b, orbits the pair of stars in less than 50 days. It is thought to be a sweltering world, where the destruction of methane in its super-heated atmosphere might lead to a thick haze that could blanket the planet. At three times the radius of Earth, Kepler-47b is the smallest known transiting circumbinary planet. The outer planet, Kepler-47c, orbits its host pair every 303 days, placing it in the so-called 'habitable zone,' the region in a planetary system where liquid water might exist on the surface of a planet. While not a world hospitable for life, Kepler-47c is thought to be a gaseous giant, slightly larger than Neptune, where an atmosphere of thick bright water clouds might exist. For more ...

NASA’s New Horizons Team Reveals New Scientific Findings on Pluto
During a July 24 science update at NASA headquarters, new surprising imagery and science results were revealed from the recent flyby of Pluto, by the New Horizons spacecraft. These included an image from the Long Range Reconnaissance Imager or (LORRI) – looking back at Pluto – hours after the historic flyby that shows haze in the planet’s sunlit atmosphere, that extends as high as 80 miles above Pluto’s surface – much higher than expected. Models suggest that the hazes form when ultraviolet sunlight breaks apart methane gas. LORRI images also show evidence that exotic ices have flowed – and may still be flowing across Pluto’s surface, similar to glacial movement on Earth. This unpredicted sign of present-day geologic activity was detected in Sputnik Planum – an area in the western part of Pluto’s heart-shaped Tombaugh Regio. Additionally, new compositional data from New Horizons’ Ralph instrument indicate that the center of Sputnik Planum is rich in nitrogen, carbon monoxide, and methane ices.

Pluto in a Minute, How Did New Horizons Get to Pluto
Designing a trajectory for a flyby mission to Pluto involves working backwards from what you want to do when you get into the system, at least, that's the way Yanping Guo approached the problem. She began by looking at the science the team wanted to get done while at Pluto, and there were two very interesting design constraints, namely, there were two occultations, one from the Sun and one from the Earth. The spacecraft had to fly behind Pluto and have both the Sun and the Earth on the opposite side of the planet at the same time. There are only two times in the Earth year when that happens, once in January and once in July.

Solar Flares Fire Up Protons, Make Gamma Rays
Solar flares produce gamma rays by several processes, one of which is illustrated here. The energy released in a solar flare rapidly accelerates charged particles. When a high-energy proton strikes matter in the sun's atmosphere and visible surface, the result may be a short-lived particle -- a pion -- that emits gamma rays when it decays.

Starry Night Tango
This simulation, which represents a few billion years of evolution, shows two disk galaxies interacting in a graceful gravitational dance. The color represents the temperature of the gas in the galaxies. The simulation shows how gravity can rearrange the gas and stars in galaxies during these interaction events, fueling the supermassive black holes at the centers of each galaxy. Radiation from the energized black holes can heat up the gas and blow it away, causing the outbursts seen in the animation.

The Solar Cycle
Although it may look unchanging from the ground, the sun actually has a long-term pattern of change called the sunspot cycle. During one cycle the number of sunspots, and solar activity, increases and then decreases again. This process is driven by the flipping of the sun's poles.

00:04:02
The Surprising Power of Solar Storms
NASA-funded researchers say a flurry of solar storms from March 8-10, 2012 dumped enough energy in Earth's upper atmosphere (our thermosphere absorbed 26 billion kWh of energy) to power every residence in New York City for two years as recorded by the SABER instrument onboard NASA's TIMED satellite. This energy temporarily increases the drag on low-orbiting satellites, which decreases their lifetime by bringing them closer to the day of re-entry. There is a plus side; extra drag helps clear space junk out of Earth orbit.

Total Solar Eclipse Australia - Nov. 13, 2012
On Nov. 13, 2012, a narrow corridor in the southern hemisphere experienced a total solar eclipse. The corridor lay mostly over the ocean but also cut across the northern tip of Australia where both professional and amateur astronomers gathered to watch. During a solar eclipse one can see – using appropriate instruments to protect the eyes since you should never look at the sun directly – dim structures around the edges of the sun. These structures are the sun's atmosphere, the corona, which extends beyond the more easily seen surface, known as the photosphere. In modern times, we know that the corona is constantly on the move. Made of electrified gas, called plasma, the solar material dances in response to huge magnetic fields on the sun. Structural changes in these magnetic fields can also give rise to giant explosions of radiation called solar flares, or expulsions of solar material called coronal mass ejections, CMEs – which make the corona a particularly interesting area to study.

Voyager 1 Explores the 'Magnetic Highway'
This set of animations show NASA's Voyager 1 spacecraft exploring a new region in our solar system called the 'magnetic highway.' In this region, the sun's magnetic field lines are connected to interstellar magnetic field lines, allowing particles from inside the heliosphere to zip away and particles from interstellar space to zoom in.

00:00:14
Voyager 2 Observes Energetic Electrons
This animation shows the Voyager 2 observations of energetic electrons. Voyager 2 detected a dramatic drop of the flux of electrons as it left the sector region. The intense flux came back as soon as Voyager 2 was inside the sector region. Energetic particles have a hard time “navigating” through the sea of bubbles. The bubbles act like traps for these particles. When particles escape the sea of bubbles and access the field lines that connect back to the Sun, they quickly escape along the magnetic field lines, very much like entering a highway. These observations were the unexpected signature of the new scenario.

Voyager Finds Magnetic Foam at Solar System's Edge
The Voyager satellites are now traveling through the outer edge of the solar system, called the heliosheath. Using a computer model based on Voyager data, scientists have shown that the sun's magnetic field becomes bubbly in this region due to reconnection. Because of this, cosmic rays must slowly work their way through the magnetic foam before continuing on toward the sun.

Why do we explore? Simply put, it is part of who we are, and it is something we have done throughout our history. In NASA’s new video, “We Are the Explorers,” we take a look at that tradition of reaching for things just beyond our grasp and how it is helping us lay the foundation for our greatest journeys ahead.

Webb Telescope- Evolution of the Universe
Galaxies congregate in clusters and superclusters, and at larger scales superclusters seem to blend into chains and filaments that span vast distances. This so-called cosmic web seems to be the foundation on which the universe is built. Webb will explore how stars, young galaxies and dark matter worked to create large-scale cosmic structure.

Why Are We Seeing So Many Sungrazing Comets?
Before 1979, there were less than a dozen known sungrazing comets. As of December 2012, we know of 2,500. Why did this number increase? With solar observatories like SOHO, STEREO, and SDO, we have not only better means of viewing the sun, but also the comets that approach it. SOHO allows us to see smaller, fainter comets closer to the sun than we have ever been able to see before. Even though many of these comets do not survive their journey past the sun, they survive long enough to be observed, and be added to our record of sungrazing comets.

WMAP- From the Archives
On June 20, 2012, Dr. Charles Bennett and the WMAP science team were awarded the 2012 Gruber Cosmology Prize. The Wilkinson Microwave Anisotropy Probe (WMAP) was launched by NASA to measure the universe’s oldest light. By making precise measurements of temperature patterns in this light, WMAP has answered many longstanding questions about the universe's age, composition and development.

X-31 Herbst Turn
The X-31 program demonstrated the value of thrust vectoring (directing engine exhaust flow) coupled with advanced flight control systems, to provide controlled flight during close-in air combat at very high angles of attack. The result of this increased maneuverability is an airplane with a significant advantage over conventional fighters.

X-ray Nova Reveals New Black Hole
An X-ray outburst caught by NASA's Swift on Sept. 16, 2012, resulted from a flood of gas plunging toward a previously unknown black hole. Gas flowing from a sun-like star collects into a disk around the black hole. Normally, this gas would steadily spiral inward. But in this system, named Swift J1745-26, the gas collects for decades before suddenly surging inward.

The X-Ray Sun Over 5.5 Years
Behold five and a half years worth of full-sun observations from XRT. A dramatic illustration of the solar cycle, this movie begins about one year before the first reversed-polarity sunspot ushered in the current cycle on January 8, 2008. The solar cycle is a periodic variation in the Sun's activity that is caused by the gradual 'tangling' and eventual reversal of its magnetic field.
