Jeff’s Earth – Amazing HD Video from ISS

On his most recent trip the International Space Station (Expedition 48),recently-retired NASA astronaut Jeff Williams has recorded a great HD video of Earth using an Ultra High Definition video camera.

Here in the video titled “Jeff’s Earth” below, he shares some of those images and talks about the beauty of the planet, the variety of things to see, and the value of sharing that perspective with everyone who can’t go to orbit in person.

Leaving Solar System at the Speed Of Light

Our Solar system is big, and vast, despite it is really small compared to our galaxy, not to mention the complete universe. To put this into a perspective, you can think of yourself as a photon emitted by the Sun. It takes about 8 minutes to reach the Earth after a photon has been emitted from the Sun’s surface. And it takes 5 hours to get out to Pluto from the Earth. The edge of the Solar System is far beyond the orbit of Pluto.

Great American Total Solar Eclipse 2017

There will be a total solar eclipse on Monday, Aug. 21, 2017, and the United States will be the best country to watch. It will be also the first total solar eclipse to go coast to coast in the U.S. in 99 years. From Oregon to South Carolina, 70-mile Moon-shadow will race across the U.S. and it will completely block out the Sun for a few minutes. It’s still more than seven months away, but hotels already are selling out as people prepare for the rare and amazing event.

On January 5, 2017, NASA has published the map of the event’s path announcing “…thanks to elevation data of the moon from NASA’s Lunar Reconnaissance Orbiter, or LRO, coupled with detailed NASA topography data of Earth, we have the most accurate maps of the path of totality for any eclipse to date.”

How Mars would look if it still had water

What if Mars still had liquid water on its surface and a thick atmosphere filled with clouds, like Earth? How would it look like? Software engineer Kevin Gill of JPL (NASA’s Jet Propulsion Laboratory) wondered this and prepared an image using data from NASA’s Mars Reconnaissance Orbiter (MRO)(1) and Mars Orbiter Laser Altimeter (MOLA)(2). The result is stunning!

Gill picked an arbitrary sea level and used GIMP (a free and open-source raster graphics editor used for image retouching and editing) to paint the features onto the satellite images using these measurements.

Scale of the Solar System (and the first flybys of planets)

Previously I posted two articles titled “If The Moon Were Only 1 Pixel – A Tediously Accurate Map Of The Solar System“, and “A Scale Model of Solar System Drawn in the Desert and the Result is Stunning“. Since the human brain cannot deal with the really large numbers, these articles provide an amazing way to understand how big actually our Solar System is.

Now, I decided to put the Solar System into scale as an infographic. You can see a scaled Solar System below, the planets’ distances from the Sun, and the first flybys over them. Plus some statistics about the planets and our home planet, the Earth.

A Year of Earth From a Million Miles Away

A year after returning its first image, NASA’s EPIC camera, a four megapixel CCD camera and telescope attached the Deep Space Climate Observatory (DSCOVR) shows us an entire year of Earth from almost one million miles away. The result is the amazing video below.

With the voice of Jay Herman, EPIC lead scientist.

NASA Releases 360 Degrees Interactive Image of Mars

On February 2016, NASA has released an interactive 360 degrees image of Mars, and you can see it on the popular video uploading site youtube. You can see our neighbor planet’s surface with your own eyes, in ultra HD!

The component images of this scene were are taken at downwind face of “Namib Dune” on Dec. 18, 2015, by the Mast Camera (Mastcam) on NASA’s Curiosity Mars rover during the 1,197th Martian day, or sol, of the rover’s work on Mars. They include a portion of Mount Sharp(1) on the horizon. You can use the arrows in the top left, or click and drag your cursor or mouse, to move the view up/down and right/left.
