The Majestic Realm of a Forgotten World: The Alluring Mysteries of Uranus

A false-color photograph of Uranus, its rings, and 10 of its moons, taken by the Hubble Space Telescope’s Near Infrared Camera and Multi-Object Spectrometer in near-infrared wavelengths. As seen in this photo, there’s so much more to see on Uranus than meets the eye. This enigmatic world deserves a dedicated space mission to be [...]

Ultimate Pathfinder: NASA's Voyager Spacecraft Enters Interstellar Space

NASA announced today under much fanfare that the agency’s Voyager 1 spacecraft, which launched from Cape Canaveral Air Force Station over three decades ago, has entered interstellar space, becoming the [...]

Hubble Space Telescope Discovers New Moon Orbiting Neptune

This composite image from the Hubble Space Telescope shows the location of Neptune’s newest known moon, S/2004 N 1, which was discovered by Mark Showalter of the SETI Institute. The black and white portion and the color inset were both taken in 2009. Image Credit: NASA, ESA, and M. Showalter (SETI Institute).

Between them, they have spent nearly five decades sending robotic explorers to almost every planet—and a few “non-planets,” too—in our Solar System. Missions bound for Mars, Jupiter, Saturn, Uranus, [...]

NASA Invites the Public to Fly Along with Voyager

The public will be able to fly along with NASA’s Voyager spacecraft as the twin probes head towards interstellar space, which is the space between stars. As indicated in this artist’s concept, a regularly updated gauge using data from the two spacecraft will indicate the levels of particles that originate from far outside our [...]

How Long Do The Voyager Spacecraft Have Left?

When will we lose contact with NASA’s Voyager spacecraft? Just to clarify the question, the problem won’t be about our hearing them, but about the spacecraft ceasing to transmit once they run out of electrical power. [...]

Reaching for the Stars Part 1: First Steps

Will we ever be able to send spacecraft to the stars in a reasonable amount of time? The big problem—and [...]

A Bum Deal: ‘Boring’ Uranus Turns ‘Interesting’

Viewed from 600,000 miles beyond the planet on 25 January 1986 – a day after closest approach – this Voyager 2 image reveals Uranus as a mere sliver of a crescent. This was the last occasion on which human eyes would glimpse the strange, topsy-turvy world in close-up. Our next robotic visitor to the [...]

Voyagers Press On Towards the Edge

The Voyagers have each passed their 35th birthdays and – despite having had several scientific instruments shut down, due to power limitations, in recent years – they both continue to enhance our understanding of the outer reaches of the Sun’s realm. Image Credit: NASA

If you are a traditionalist, you might choose a gift [...]
