A collection of media resources to supplement the NISE Network's Explore Science: Earth
- [2017 - Orbiting Objects] This artist’s rendering illustrates new findings about a star shredded by a black hole. When a star wanders too close to a black hole, intense tidal forces rip the star apart. In these events, called “tidal disruptions,” some of the stellar debris is flung outward at high speed while the rest falls toward the black hole.
- [2017 - Orbiting Objects] Planets emerge from the dense disk of gas and dust encircling young stars. A good visualization that complements the Gravity Well and seeing what happens when you create a "dust cloud" of objects by throwing many marbles into the Gravity Well.
- [2017- Imagining Life] What kind of atmospheres are possible on exoplanets? On May 4th, 2016, the Hubble Space Telescope made the first spectroscopic measurements of two of the three known Earth-sized exoplanets in the TRAPPIST-1 system just 40 light-years away. Knowing more about the atmospheres of exoplanets can help scientists consider the possibilities for alien life.
- [2017 - Imagining Life and Ice Orbs] A narrated video that might complement "Imaging Life" and "Icy Worlds." This extreme oasis of life deep in the Caribbean Sea may hold clues to life on other planetary bodies, including Jupiter's moon Europa.
- [2017 - Imagining Life and Ice Orbs] A great introduction and overview of NASA's efforts to find life on other planets and a fascinating bit about simulating the oceans under miles of ice on some icy moons.
- [2017 - Ice Orbs] Could a liquid water ocean beneath the surface of Jupiter’s moon Europa have the ingredients to support life? Here's how NASA's mission to Europa would examine the ice. Can you find similar ice patterns on the ice orbs you used in our activity?
- [2017 - Ice Orbs] NASA's Hubble Space Telescope was used to find supporting evidence of water vapor plumes from the Jupiter's icy moon of Europa. The existence of water vapor plumes could provide NASA's Europa flyby mission the opportunity to study the conditions and habitability of Europa's subsurface ocean.
- [2017 - Investigating Clouds] Between October 1 and October 22, NASA asked museums and science centers around the world to participate in a global experiment collecting observations of clouds while NASA satellites were overhead. As part of the part of International Science Center and Science Museum Day (ISCSMD), the experiment built upon UNESCO’s theme of “Science for Peace and Development.” More than 900 cloud observations, including more than 5,500 photos, came in. The white dots on this map show each observation submitted through the app in that period. The red dots represent science centers participating in the global experiment.
- [2017 - Solar Eclipse] This animation illustrates why there isn't an Eclipse every New Moon. The Moon's orbit is slightly tilted, and as seen in this animation, the tilt causes the Moon's shadow to miss the Earth during most New Moons—about five out of six, in fact. The olive-colored square represents the ecliptic plane, while the light blue circle shows the plane of the Moon's orbit. Unlike most illustrations of this kind, the Earth and the Moon are to scale. The Sun is off-screen to the left, about 400 times farther than the Earth-Moon distance and roughly twice as big as the Moon's orbit.
- [2017 - Solar Eclipse] Although these have no sound, you could play one or more of these visualizations on a loop before and during your Eclipse event. There are a couple visualizations to choose from and they illustrate the connection between time, location, and shadow as the moon passes in front of the Sun.
- [2017 - Solar Eclipse] On August 21, 2017, the Earth will cross the shadow of the Moon, creating a total solar eclipse. This narrated video features several visualizations of the Eclipse and uses some of the same visualizations noted in this list.
- [2017 - Bear's Shadow] For the older kids who won't be challenged by Bear Shadows, this simulator shows how your shadow will look at different times of the day and different times of the year. Why is your shadow longer in the winter than during the summer at 12 o'clock?
- [2017 - Bear's Shadow] A cute video you can play while people wait in line to do Bear Shadows. Peep, Quack, and Chirp discover their shadows — then use them to teach Tom (that trouble-making cat!) a lesson.
