Water Water Everywhere

Everyone knows that Earth is a “water-world,” with oceans covering 71% of its surface and at least as much contained within our planet’s mantle deep below its crust. But there’s also liquid water to be found elsewhere in the Solar System: on Mars, on the dwarf planets Ceres and Pluto, and also on the icy moons of Jupiter,…

This Was Rosetta’s View of Earth and the Moon in March 2005

ESA’s comet-chasing Rosetta mission is best known today for its two historic firsts of entering orbit around a comet and sending a lander onto the surface of said comet, in May and November of 2014 respectively. But Rosetta didn’t just go directly from its March 2, 2004 launch to comet 67P; it had to perform…

Astronaut Ron Garan Says Let’s Set Up a Moon Base First

Former NASA astronaut Ron Garan was recently interviewed for Huffington Post’s LIVE broadcast. Ron talked about his new book The Orbital Perspective (read my review here) along with what it was like to be an astronaut and the way his experiences changed his views of life on Earth. (He also live-narrated some of the work…

Watch This Stunning Seamless Video of Earth From Orbit

Recently featured on Universe Today, this video of Earth from space assembled by video artist Phil Selmes uses actual photos captured from the Space Station, with some fancy editing to create seamless transitions between views. It’s another beautiful presentation of the fragile oasis we call home. “I don’t see politics, races, borders, countries, religions or differences,” Selmes said in…

Only the Penitentes Shall Pass: Snow and Stars Near ESO’s ALMA

I just had to share this beautiful image by ESO photo ambassador Babak Tafreshi; it shows a star-filled night sky above the Chajnantor Plateau on the border of Chile and Bolivia, the site of the Atacama Large Millimeter/submillimeter Array (ALMA) observatory. The site, chosen for its remote location and incredibly clear, dry sky, is one of the best…

Voyager’s Valentine Turns 25 Today

If you’re in love with space exploration then you’ll fall for this: it’s the picture of Earth taken from the Voyager 1 spacecraft after it passed the orbit of Pluto in 1990. That image of our planet from almost 4 billion miles away inspired Carl Sagan to write his famous “Pale Blue Dot” passage, and…

Where Are All of Earth’s Impact Craters?

When you look up at the Moon through a telescope or pair of binoculars you see a world covered in craters of all sizes. It only stands to reason that Earth must also have craters like the Moon, if not many more because of its much larger size. So where are they all? As it…

Watch a Beautiful Timelapse Captured from Earth Orbit

ESA astronaut Alexander Gerst spent nearly six months living and working in orbit aboard the ISS during Expedition 41 in 2014, and during that time he captured some amazing photos of Earth from the windows of the Station. Watch above as aurorae dance and shimmer, stars and satellites wheel overhead, and city lights shine below…

The First Christmas From the Moon

“We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.” – Bill Anders, Apollo 8 On Christmas Eve 46 years ago, December 24, 1968, the Apollo 8 astronauts entered orbit around the Moon and came upon an amazing sight: a blue Earth “rising*” beyond the…

A Matter of Scale

Note: this post was first published on Feb. 22, 2011. I’m reposting it again today because 1. the video creator has since updated the soundtrack, and 2. it’s still awesome. One of the things that fascinates me so much about the Universe is the incredible vastness of scale, distance and size. On Earth we have…

This Is The First Photo Ever Taken of Earth From Space

These days we get to see photos of our planet taken from space literally every day. Astronauts and cosmonauts living and working aboard the ISS, weather and Earth-observing satellites in various orbits, even distant spacecraft exploring other planets in our Solar System… all have captured images of Earth from near and far. But there was…

Now You Can Watch Beautiful Live Video of Earth From Space

This is something really special, and everyone should know about it, and so I’m doing my part and sharing it here but please feel free to pass it along yourself as well. We now have publicly-accessible, high-definition video of our planet coming in live from the Space Station, thanks to the High Definition Earth Viewing…
