Watch Original Footage From the Very First Spacewalk

On March 18, 1965, the first extravehicular activity – or EVA – in space was conducted by Russian cosmonaut Aleksei Leonov, who spent ten minutes outside his Vokshod 2 spacecraft in Earth orbit. Leonov’s historic spacewalk paved the way for all future EVAs, from Ed White’s first American EVA on June 3 of the same…

Have the Best-Laid Plans of MarsOne Finally Gone Awry?

Just one month after the announcement of the 100 “finalists” selected by MarsOne – a Dutch nonprofit company that’s promising to establish a permanent colony on the Red Planet by 2025 – a scathing exposé has been published online that reveals some of the behind-the-scenes processes that have been going on for applicants, as described by selected finalist Dr….

This is What it Would Look Like to Fight Flying Dragons on Titan

Obviously this is a totally-for-fun sci-fi video, but what a video! Created by Oscar-nominated Irish filmmaker Ruairi Robinson, it shows fleets of very industrial-looking fighter skiffs hunting giant flying eels through the skies of some very cloudy planet… the first thought that came to my mind was Titan! (Although Titan is more hazy than cloudy…

Ground-Based Radar Reveals the Surface of Venus

These days if you look toward the west after sunset you’ll see a bright star that’s the first to appear in the sky – except it’s not a star at all but our neighboring planet, Venus. Covered in a dense layer of thick clouds, Venus not only reflects a lot of sunlight but also keeps its…

An Absolutely Epic Photo of Humans Returning From Space

It almost doesn’t look real but it is: the return of three humans aboard a Soyuz TMA-14M capsule after spending nearly six months aboard the ISS as part of Expedition 41/42, captured on camera by NASA photographer Bill Ingalls during their sunlit descent via parachute. The Soyuz landed in a remote area near the town of…

Suspected Hydrothermal Activity on Enceladus Raises Hopes for Life

Ever since their discovery by the Cassini spacecraft in 2005, the plumes of icy particles that are being fired into space from deep gashes along the southern pole of Saturn’s moon Enceladus have intrigued planetary scientists and astronomers immensely. Here we have a world in our own Solar System, relatively not so far away, where…

Beyond the Edge of Jupiter: Europa Rising

One of the most beautiful images of Jupiter and its ice-covered moon Europa was actually taken by the New Horizons spacecraft destined for Pluto! The view above was captured by New Horizon’s LORRI imager from a distance of 1.4 million miles from Jupiter on Feb. 28, 2007 just after it made its closest pass of…

What is a Neutron Star, Anyway?

Neutron stars are strange cosmic beasts. Stellar corpses that are several times the mass of our Sun but only about the width of Manhattan, they can contain a mountain’s worth of star-stuff within the space of a sugar cube, creating all sorts of weird physics that requires funny-sounding names like “quark-gluon plasma” to even try to describe what’s…
