Triton’s Dramatic Fade
The above picture of Triton, Neptune’s moon was taken in 1989 by the only spacecraft ever to pass Triton: Voyager 2. Voyager 2 found fascinating terrain, a thin atmosphere, and even evidence for ice volcanoes on this world of peculiar orbit and spin. Ironically, Voyager 2 also confirmed the existence of complete thin rings around Neptune.

“I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up—many people feel small, because they’re small and the Universe is big, but I feel big, because my atoms came from those stars” - Neil deGrasse Tyson
Just when you thought that Dr. Tyson’s video exploration of everything that makes us special in our world and beyond couldn’t get any better, it gets the GIF treatment. Nice work.
Watch it again, and then again.

Pulsar stars could be the perfect interstellar GPS system
When humanity sends spacecraft beyond our solar system, those starships will have to know exactly where they are at all times. A newly proposed cosmic GPS system can track a spacecraft’s location to within five kilometers anywhere in the galaxy.
The secrets to this system are pulsars, a special type of neutron star that rotate at short, extremely regular intervals. That last bit is crucial - because we can count on pulsars to always rotate at the exact same speed, which makes them useful timekeepers across even the vast reaches of space. Indeed, some pulsars that rotate every few milliseconds are actually comparable to atomic clocks in terms of precision and dependability.

An astronomer’s paradise
Cerro Paranal, in the high, dry, Atacama desert in Chile, is where some of the best astronomy in the world is done. It’s graced with incredibly dark and steady skies, and a view of the southern hemisphere skies that, frankly, makes me jealous.

ATV-3 approaches the ISS
European Space Agency’s “Edoardo Amaldi” Automated Transfer Vehicle-3 (ATV-3) approaches the International Space Station. The unmanned cargo spacecraft docked to the space station at 6:31 p.m. (EDT) on March 28, 2012, delivering 220 pounds of oxygen, 628 pounds of water, 4.5 tons of propellant, and nearly 2.5 tons of dry cargo, including experiment hardware, spare parts, food and clothing.

Supernovae popping off like firecrackers in Carina
The Carina nebula is a sprawling, monstrous complex of gas located a mere 7500 light years from Earth. Hundreds of light years across, it’s massive enough to create thousands of stars like the Sun. Tens of thousands.
And churn out stars it does. Embedded in the nebula are several clusters of newborn stars, and many of these stars are so massive they’re nearly at the limit of how big a star can be without tearing itself apart. Stars that big explode as supernovae, and a new mosaic by the orbiting Chandra X-ray Observatory indicate they’ve been popping off in the nebula for quite some time
