On April 3, 2009, countries from around the world participated in the '100 Hours of Astronomy' webcast to celebrate the International Year of Astronomy. Produced to support the webcast, this movie highlights the discoveries of the SOHO...

A countdown of the top 5 solar discoveries from the Sun-Earth Connection Education Forum. These include the discoveries of sunspots, the solar cycle, the heliosphere, aurora formation, and space weather. Number 2 in the Top 5 Solar...

This dominant cosmological theory suggests the Universe began nearly 13.7 billion years ago, expanding rapidly from a very dense and incredibly hot state. Eventually, stars ignited and galaxies slowly formed. The Big Bang theory has been...

One of the keys to gathering data for Operation IceBridge is a highly modified McDonnell Douglas DC-8 jetliner, which NASA operates as a flying science laboratory. This workhorse DC-8 can fly long trips, allowing a suite of scientific...

The NOAA-N Prime satellite is slated for launch by NASA on February 4th, 2009. Operated by NOAA, N Prime will be the last in the Television Infrared Observation Satellite Series (TIROS) that have been observing Earth’s weather and...

Space shuttle Atlantis met up with the Hubble Space Telescope today. The grapple of the telescope using the shuttles robotic arm took place at 1:14 p.m. EDT. The telescope will be latched to a high-tech, lazy Susan device known as the...

The Hubble Space Telescope has been with us for nearly two decades. In that time, its breathtaking images have captured peoples imaginations and its groundbreaking science has revealed some of the many secrets of our universe. After five...

NASA's GLAST mission is an astrophysics and particle physics partnership, developed in collaboration with the U.S. Department of Energy, along with important contributions from academic institutions and partners in France, Germany,...

Students learn the basics of graphing with a little help from NASA's BEST (Beginning Engineering, Science, and Technology). Or get tweeted by NASA:

Two new species of fungi have been discovered that devour flies from the inside and cause them to release spores from holes in their abdomens, according to research published in the Journal of Invertebrate Pathology

The Space Operations Control Center, also known as the STOCC, is responsible 24/7, 365 days a year for monitoring all Hubble systems and facilitating all of the telescope's science observations. Two teams of flight controllers designated...

Hubble Space Telescope Servicing Mission 4 is the last time humans will visit Hubble. NASAs scientists, engineers and astronauts are working together to make Hubble better than it has been before. See what NASA has planned for this last...

Mike Mumma and his team of researchers at Goddard Space Flight Center have made the first definitive observations of methane in the atmosphere of Mars. The evidence of methane plumes only during certain seasons and the chemical processes...

Mathematician Jan McGarry discusses the science and history of Satellite Laser Ranging (SLR), her role in developing the Next Generation Satellite Laser Ranging system, and her career at NASA's Goddard Space Flight Center.

Fill'er up! That's the promise of robotic refueling on orbit: aging satellites can get a new lease on life from a robotic machine making a service call. Or, at least, the dream of such a system got dramatically closer after NASA's...

The Hubble Space Telescope would not be able to produce its breathtaking science without the upgraded infrastructure targeted during the HST SM4 mission: Fine Guidance Sensor, Scientific Instrument Command and Data Handling, Soft Capture...

The Lunar Reconnaissance Orbiter (LRO) is the first mission in NASA's planned return to the moon. LRO is an unmanned mission to create the comprehensive atlas of the moon's features and resources necessary to design all future lunar...

Sample Analysis at Mars (SAM) is a suite of instruments developed for use on the Mars Science Laboratory. By looking for evidence of water, carbon, and other important building blocks of life in the Mars soil and atmosphere, this suite...

The Lunar Reconnaissance Orbiter is a first step to future missions, Mars, and beyond. But a lot has to happen before we get there and one woman played a key role.

Keith Walyus describes the experience of the Servicing Mission 4 spacewalks as head of communications in the Goddard STOCC. The Space Operations Control Center, also known as the STOCC, is responsible 24/7, 365 days a year for monitoring...

NASA’s Operation IceBridge is back in the field, but this time, there’s a twist. Instead of using the P-3 or DC-8 aircraft from previous campaigns, they’ve outfitted a C-130 cargo plane for the trip. Science flights begin this week as...

After a four and a half day journey from the Earth, the Lunar Reconnaissance Orbiter, or LRO, has successfully entered orbit around the moon. Engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., confirmed the spacecraft's...

This 4K visualization shows the Moon's phase and libration at hourly intervals throughout 2021, as viewed from the Southern Hemisphere. Each frame represents one hour. In addition, this visualization shows the Moon's orbit position,...

Arctic sea ice declined this summer to its second smallest extent in the satellite era, suggesting that the record set in 2007 may not have been an anomaly. If recent trends in the melt rate continue, we could see a virtually ice-free...
