NASA | X-ray 'Echoes' Probe Habitat of Monster Black Hole
NASA | X-ray 'Echoes' Probe Habitat of Monster Black Hole
Astronomers using data from the European Space Agency's XMM-Newton satellite have found a long-sought X-ray signal from NGC 4151, a galaxy that contains a supermassive black hole. The discovery promises a new way to unravel what's happening in the neighborhood of these powerful objects. Most big galaxies host a big central black hole containing millions of times the sun's mass. When matter streams toward one of these supermassive black holes, the galaxy's center lights up, emitting billions of times more energ

NASA | Incandescent Sun
This video takes SDO images and applies additional processing to enhance the structures visible. While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun. The original frames are in the 171 Angstrom wavelength of extreme ultraviolet. This wavelength shows plasma in the solar atmosphere, called the corona, that is around 600000 Kelvin. The loops represent plasma held in place by magnetic fields. They are concentrated in "active regions" where the magnetic fields are the strongest. These active region

NASA | TDRS: Heart of Communication
The most recent evaluations of NASA's Tracking and Data Relay Satellite (TDRS) project confirmed all systems go for TDRS-K, a third generation upgrade of the orbiting communications network. TDRS-K is scheduled for launch aboard an Atlas V rocket from Cape Canaveral, Florida during the 2012 holiday season. The launch of TDRS-K will begin the replenishment of the fleet through the development and deployment of the next generation spacecraft. These satellites will ensure NASA's Space Network continues to provide around-the-clock, high throughput com

NASA | Forest Recovering From Mt St Helens Eruption
The 1980 eruption of Mount St. Helens leveled surrounding forest, blasted away over a thousand feet of the mountain's summit, and claimed 57 human lives. Landsat satellites have tracked the recovery of the surrounding forest. This video shows that recovery, in a timelapse of annual images from 1979-2011.

NASA | Earth Day 2012 Video Contest
Create NASA Earth Day Video, Win Seats To A Launch www.nasa.gov From the first television images of Earth from space, to the now iconic Apollo photographs of Earth, to Voyager's "pale blue dot," NASA has changed how we think about exploring Earth and even how we see Earth. Looking back from space provides far more than thought-provoking pictures. NASA's fleet of Earth-observing satellites orbits our planet multiple times each day, scanning the air, land and seas for critical information about how our planet behaves and how it is changing

NASA | GPM: The Fresh(water) Connection
The Global Precipitation Measurement (GPM) is an international satellite mission to provide next-generation observations of rain and snow worldwide every three hours. NASA and the Japan Aerospace Exploration Agency (JAXA) will launch a "Core" satellite carrying advanced instruments that will set a new standard for precipitation measurements from space. The data they provide will be used to unify precipitation measurements made by an international network of partner satellites to quantify when, where, and how much it rains or snows around the

NASA | Afterschool Universe: Stellar Fusion Demonstration
Afterschool Universe is an out-of-school-time astronomy program for middle school students that explores basic astronomy concepts through engaging hands-on activities and then takes participants on a journey through the Universe beyond the Solar System. This video shows a simple activity with clay that demonstrates the stages of fusion within the core of a star. Depending on its mass, a star can fuse and create many different elements before it finally runs out of fuel. If you are interested in the Afterschool Universe program, visit

NASA | Fermi Provides New Insights on Dark Matter
NASA | Fermi Provides New Insights on Dark Matter
There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. Yet, despite decades of effort, no one knows what this "dark matter" really is. Many scientists think it's likely that the mystery will be solved with the discovery of new kinds of subatomic particles, types necessarily different from those composing atoms of the ordinary

NASA | LRO Brings "Earthrise" to Everyone
On December 24, 1968, Apollo 8 Commander Frank Borman and crew members William A. Anders and James A. Lovell, Jr. became the first humans to photograph the Earth rising over the moon. Now, the rest of us can see what it was like in a new NASA visualization that draws on richly detailed maps of the moon's surface made from data gathered by NASA's Lunar Reconnaissance Orbiter! The narration in this visualization comes from the original audio recording of the Apollo 8 astronauts. The flight time has been compressed for effect. The Ear

NASA | IBEX: Observing the Sun's Horizon
The Interstellar Boundary Explorer, or IBEX, is the first mission designed to map the entire region of the boundary of our Solar System. As charged particles from the Sun, called the "solar wind," flow outward well beyond the orbits of the planets, they collide with the material between the stars, called the "interstellar medium" (ISM). These interactions create energetic neutral atoms (ENAs), particles with no charge that move very quickly. This region emits no light that can be collected by conventional telescopes so, instea

NASA | Discovery Comes to Dulles
NASA | Discovery Comes to Dulles
On April 17, 2012 the space shuttle Discovery hitched a ride on the back of a 747 jumbo jet especially designed as a space shuttle transport. It landed at Dulles Airport in Washington, DC, and the process to deliver Discovery to its new home at the Steven F. Udvar-Hazy Center got under way. Through the eyes of a veteran NASA tour guide and aficionado, DJ Emmanuel, we get a behind-the-scenes view of what it was like to be there on such an historic and exciting day!

NASA | A Big Blast
NASA | A Big Blast
A beautiful prominence eruption producing a coronal mass ejection (CME) shot off the east limb (left side) of the sun on April 16, 2012. Such eruptions are often associated with solar flares, and in this case an M1 class (medium-sized) flare occurred at the same time, peaking at 1:45 PM EDT. The CME was not aimed toward Earth.
