Life and Death of a Planetary System – Exoplanet Exploration: Planets Beyond our Solar System | NASA Exoplanet Program

Seven chapters describe an interstellar journey through time and scientific work on how planetary systems form. The online article includes Q and A's, news updates, and video clips. The article is organized by a timeline.

 

Scale of the Solar System with accurate rotations (remastered) | James O'Donoghue @physicsJ | #solarsystem #visualization

This animation is to help understand the size scales of the Solar System, along with the roation rates of the planets. At all times, the scale of the planets and the Sun are accurate. Images are from NASA.

Now with Pluto and Ceres:

Shown: rotation, tilt, sidereal day, Tilts are "Obliquity to orbit" as there are multiple definitions of "axial tilt." There are still many unmapped dwarf planets. (source)

Do the moons of Mars or the moons of Jupiter or moons of Pluto cause a total solar eciipse for those planets? What about the rings of Saturn? Watch this 5:04 video by Dianna Cowern or the Physics Girl to find out.

Comics drawn (and the process explained) by JoAnna Wendel for AGU's magazine Eos. The comic is based on an article, “Six Things Dwarf Planets Have Taught Us About the Solar System,”

In 250 million years Earth might only have one continent | @BBCEarth | #geology #tectonics

This BBC article covers all about the development of plate tectonics. The article interviews Scotese and includes two of his video animations, future plate motions & Pangea Proxima and from 750 Ma to present. The article reviews the work of Wegener, Tharp, Hess along with a review of fossil evidence and concludes with current investigations, including other planets.

Star Size Comparison 2 | YouTube video by morn1415

This 6:50 YouTube video compares the size of different planets and stars in the Universe. It starts with our Moon and then sizes up to planets in our solar system in a line up while also looping in other rocky planets and bright stars. It is a sequel to the size comparison video made 7 years earlier https://www.youtube.com/watch?v=HEheh1BH34Q >. This one, though, is even more spectacular because it visualizes the distance of space in light days and light years so well.

NASA’s Eyes on Earth, Solar System & Exoplanets | #OER #EarthRightNow #visualization #apps

Monitor our planet's vital signs, such as sea level height, atmospheric carbon dioxide concentration and Antarctic ozone. Trace the movement of water around the globe using the gravity map from NASA's GRACE satellites. Spot volcanic eruptions and forest fires using the carbon monoxide vital sign. Check out the hottest and coldest locations on Earth with the global surface temperature map. Observe Earth from a global perspective in an immersive, 3-D environment.

Eyes on the Solar System lets you explore the planets, their moons, asteroids, comets and the spacecraft exploring them from 1950 to 2050. Eyes on Exoplanets will fly you to any planet you wish—as long as it’s far beyond our solar system. Look at more than 1,000 exotic planets known to orbit distant stars.
