During the course of the video, the sun subtly increases and decreases in apparent size. This is because the distance between the SDO spacecraft and the sun varies over time. The image is, however, remarkably consistent and stable despite the fact that SDO orbits the Earth at 6,876 miles per hour and the Earth orbits the sun at 67,062 miles per hour. (05:04)

If you want to learn more about the history of Earth and other rocky planets in the solar system, craters are a great place to look. Now, thanks to LRO's LROC instrument, we can take a much closer look at Linne Crater on the moon--a pristine crater that's great to use to compare with other craters! (02:33)

From June 2002 to early October 2011, the Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E) on the Aqua satellite provided a wealth of data about the Earth's water cycle. Among the many variables calculated from AMSR-E data are sea surface temperature, atmospheric water vapor, rainfall, Arctic and Antarctic sea ice coverages, and snow cover. (03:58)

Watching a particularly beautiful movie of the sun helps show how the lines between science and art can sometimes blur. But there is more to the connection between the two disciplines: science and art techniques are often quite similar, indeed one may inform the other or be improved based on lessons from the other arena.

Botswana's Okavango Delta and the Makgadikgadi Salt Pans are two ends of a 360-mile round trip zebra migration, the second longest on Earth. In this animation, shades of red show dry areas, green represents vegetation, and the dots show GPS tracked zebras. The zebras begin at the Okavango Delta in late September. After the dry Southern hemisphere winter, November rains signal it is time to begin their two-week journey to the Salt Pans. The zebras feast on nutrient-rich grasses all summer, and return to the Delta as the rain peters out in April. (01:50)

A study of 544 star-forming galaxies observed by the Keck and Hubble telescopes shows that disk galaxies like our own Milky Way unexpectedly reached their current state long after much of the universe's star formation had ceased. Over the past 8 billion years, the galaxies lose chaotic motions and spin faster as they develop into settled disk galaxies.

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 kinesthetic activity that demonstrates how all the information we obtain about objects in the universe is carried to us by light, and it takes time for light to travel to us from those objects. The amount of time it takes depends on how far away they are.

This animation compares the X-ray 'heartbeats' of GRS 1915 and IGR J17091, two black holes that ingest gas from companion stars. GRS 1915 has nearly five times the mass of IGR J17091, which at three solar masses may be the smallest black hole known. (01:32)

Sea ice doesn't always hold the allure of a massive ice sheet, or a crevassed blue glacier spilling between mountains, but it comes in array of shapes and sizes and has its own ephemeral beauty. Operation IceBridge studies sea ice at both poles, and also runs across interesting formations on route to other targets. (02:36)

The sun emitted a significant solar flare on Oct. 22, 2012, peaking at 11:17 p.m. EDT. The flare came from an active region on the left side of the sun that has been numbered AR 1598, which has already been the source of a number of weaker flares. (00:39)

The Landsat Data Continuity Mission will continue and improve upon the 40-year-old Landsat program. This video examines two uses of Landsat data to monitor agriculture. Both wineries and timber companies rely on Landsat data to check whether their vines and trees are getting enough (or too much) water and fertilizer. The small resolution and regular repeat cycle of the satellite data is crucial to monitoring the health of their crops. (03:44)

The Evaporative Stress Index (ESI) provides objective, high-resolution information about the evaporation of water from land surface. The ESI model combines satellite data with other meteorological factors to determine how much water is used by crops and vegetation. The resulting data helps to detect drought. The kind of early-warning detection system ESI provides will enhance the US arsenal of drought monitoring tools and help farmers adapt to drought before it evolves. (01:47)

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 matter all around us. The search to detect and identify these particles is underway in experiments both around the globe and above it. (03:12)

Although the Moon has remained largely unchanged during human history, our understanding of it and how it has evolved over time has evolved dramatically. Thanks to new measurements, we have new and unprecedented views of its surface, along with new insight into how it and other rocky planets in our solar system came to look the way they do. (04:39)
