Jon Culshaw

Exoplanet Excursions: January 2015

Jon’s eclipse-chasing desire leads him to Piscis Austrinus for an interstellar perspective.

One of the most spectacular coincidences on Earth is the very fact that total solar eclipses take place: that the Sun is both 400 times larger than the Moon and 400 times further away from us.

 

Exoplanet Excursions: December 2014

Jon journeys to one of Pluto’s compatriots, a dwarf planet in our own Kuiper Belt

Having pushed the Cruiser Globe to its limits recently, I’m mindful to stay more local this excursion.

Exoplanet Excursions: November 2014

Jon‘s endeavour to find the source of an X-ray flare takes him to the edge of oblivion.

From Earth, a small telescope will unveil NGC 4845 as a spiral galaxy in Virgo, shining at a magnitude of +11.2

Exoplanet Excursions: October 2014

Jon heads into the Milky Way’s bulge, to a region where the stars are legion.

One of my greatest astronomical fascinations is imagining the kind of night sky visible from the centre of our Galaxy, that massive sphere of densely packed stars called the ‘galactic bulge’.

Exoplanet Excursions: September 2014

Jon takes another leap into the future to witness the eventual fate of a star like ours.

With great trepidation I must visit the system of Kepler 56. This star, some 2,800 lightyears away and around four times the size of our Sun, has become what’s known as a ‘G0V’. It has crossed that critical, irreversible borderline on its transition to the status of a red giant.

Exoplanet Excursions: August 2014

Jon pops 40 years into the future to hear a METI transmission reach its destination.

I’ve decided to stay in the 55 Cancri system a little longer to visit a moon of 55 Cancri f, a gas giant contentedly perched at the heart of its star’s habitable zone.

Exoplanet Excursions: July 2014

Jon travels to a planet where the mountains are capped not with snow, but diamonds.

The astonishing alien splendour of the Upsilon Andromedae system enthralled the senses – it seems fitting that the first multi-planetary system around a main sequence star discovered by humans should be such a spectacular one.

Exoplanet Excursions: June 2014

Holy hot Jupiters Batman – it’s a multiple planetary system around a main-sequence star.

My excursions tend to evoke one of two moods in me: a fascination with violent extremes or a thirst to see peaceful alien vistas of breathtaking beauty.

Exoplanet Excursions: May 2014

Neither planet nor star, Jon’s next stop sits in the murky borderlands of cosmic classification.

Drifting through the Galaxy like a dirty faced Dickensian orphan trudging up a foggy, cobbled road, the wandering rogue world I encountered on my last voyage – Obsidiana – evoked an odd feeling of pity.

Exoplanet Excursions: April 2014

Jon swaps paradise for thick ice as he continues his tour of the Kepler 62 system.

Sitting at the controls of the Cruiser Globe, I’m gripped by an urge to experience the unfathomable infinity of the Universe.
