Voyager is in a new region of space, and now that place has a name

"Now, voyager, sail thou forth, to seek and find"

Say hello to a brand new bit of the solar system, brought to you by that intrepid traveller Voyager 1: the heliosheath depletion region. Ok, the name’s not particularly catchy, but this is exciting news! Voyager launched over 35 years ago, but it was just before that anniversary last year that it entered this new, [...]

Good morning Gliese 526, the Earth says hello

LoneSignal

Over the years we’ve sent a lot of stuff into space. Most of that has been spacecraft sent out to explore the solar system — the moon and sun, planets and asteroids. With Voyager poised on the edge of the sun’s influence, we’ll eventually be able to add a tiny pocket of interstellar space to [...]

What Voyager saw: a journey in photographs #scio13

On the plane to North Carolina. Clouds!

I spent this afternoon at a workshop on Rapid Media Prototyping, as part of ScienceOnline 2013 in Raleigh, North Carolina. So in the spirit of the session here is a rough and ready thing that I made… It’s a timeline of photos taken by both Voyager spacecraft on their trip through the outer solar system [...]

Voyager 1 is still not out of the solar system

"Now, voyager, sail thou forth, to seek and find"

Remember when I said back in October that Voyager 1 might have finally left the solar system? Well, it turns out that the spacecraft, which has been skirting the edge of the solar system for a long time now, is finding it difficult to say goodbye. According to scientists working on the mission, Voyager 1 [...]

Voyager 1: beyond the edge of the solar system at last?

voyager1

It was on my first birthday that the Voyager 1 spacecraft turned around and took a picture of the pale blue dot we call home. That picture was Voyager’s last glimpse of Earth before its camera was switched off and it began to sail, uninterrupted, towards interstellar space. Around the same time Voyager 2 finished [...]

Pale blue dot or not? What the colour of alien worlds can tell us

Most people are familiar with the pale blue dot image of Earth taken by Voyager in 1990. Its blueness is significant, of course, because it is Earth’s abundant liquid water that makes it look that way. But if you looked at the light that is reflected from Earth carefully, you would see several interesting features. [...]

Voyager: a binary love story

On its 35th birthday, the Voyager 1 spacecraft is a little closer to home than we had hoped it would be at this point. The Voyagers, 1 and 2, are right at this moment speeding away from us towards interstellar space. But a paper out in Nature today reports that, despite recently showing signs that [...]

Astrobiology Roundup

mosaic.001

                      Lots of new scientific results in the past couple of weeks feed directly into the central questions of astrobiology – from the search for life, to the environment of interplanetary and interstellar space, and the grand cosmological terrain we find ourselves in. No Methane [...]

Voyager Has Entered The Interstellar Medium

pia17462-640

                After many claims and statements over the past few years that Voyager 1, our most distant operating spacecraft, has ‘left the solar system’ (it hasn’t, as I explain here), it does now seem that as of August 2012 this extraordinary vehicle has entered the interstellar medium. This [...]

Voyager’s Exit To The Stars…In 17,000 Years

eso1316a

Recent debates over whether or not the Voyager 1 spacecraft has ‘left the solar system’ typically leave out some critical details. The limits of the Sun’s particle radiation is not the physical edge of the contents of the solar system, but it is the point of changeover to the exceedingly tenuous atmosphere of matter and [...]

The Fastest Spacecraft Ever?

Who's the fastest of them all? (Credit: NASA)

Of all the spacecraft humans have launched, there have been some impressively fast movers. But which holds the record? It’s not an entirely idle question. Apart from the wow factor, it’s an interesting yardstick for gauging our capacity to explore the cosmos, from familiar planets to the icy depths of space. However, as I quickly [...]

The Interstellar Internet

An interstellar web? (Original image by B. Torrissen)

A speculative but intriguing discussion that sometimes crops up when talking to people engaged in exoplanetary science goes like this; let’s suppose that we find an unmistakably terrestrial style planet around a relatively nearby star (less than about 30 light years away), perhaps even around one of the Alpha Centauri members, a touch over four [...]

Alone in the blogiverse: where are all the space-art bloggers?

Where are all the space-art bloggers?  When Symbiartic was in the planning stages, this was a post I knew I had to write. There are so few I found it at first surprising.  Do the images from the Hubble trump inspiration in painters?  Is interest in space waning compared to say, paleontology? Science inspired art [...]
