The Sun's gradual brightening will seriously compromise the Earth'sbiosphere within ∼ 109 years. If Earth's orbit migrates outward,however, the biosphere could remain intact over the entiremain-sequence lifetime of the Sun. In this paper, we explore thefeasibility of engineering such a migration over a long timeperiod. The basic mechanism uses gravitational assists to (in effect)transfer orbital energy from Jupiter to the Earth, and therebyenlarges the orbital radius of Earth. This transfer is… 
Astronomical Engineering Revisited: Planetary Orbit Modification Using Solar Radiation Pressure
As the Sun evolves along the main sequence its luminosity will grow, leading to a steadily increasing solar flux at the Earth with corresponding catastrophic consequences for the biosphere. A novel
Distant future of the Sun and Earth revisited
We revisit the distant future of the Sun and the Solar system, based on stellar models computed with a thoroughly tested evolution code. For the solar giant stages, mass loss by the cool (but not
Planetary Macro-Engineering Using Orbiting Solar Reflectors
The prospect of engineering a planetary climate raises a multitude of issues associated with climatology, engineering on truly macroscopic scales and indeed the ethics of such ventures. Depending on
The search for a strategy for mankind to survive the solar Red Giant catastrophe
In around 5 gigayears our Sun will grow to a Red Giant and will swallow Earth. The plan is subdivided into two parts: We propose to construct some kind of parasol to shadow Earth. The position of the

The collision between the Milky Way and Andromeda
We use a N{body/hydrodynamic simulation to forecast the future encounter between the Milky Way and the Andromeda galaxies, given current observational constraints on their relative distance, relative
There's No Place Like Home (in Our Own Solar System): Searching for ET Near White Dwarfs
The preponderance of white dwarfs in the Milky Way were formed from the remnants of stars of the same or somewhat higher mass as the Sun, i.e., from G-stars. We know that life can exist around
Early-Type Stars: Most Favorable Targets for Astrometrically Detectable Planets in the Habitable Zone
Early-type stars appear to be a difficult place to look for planets astrometrically. First, they are relatively heavy, and for fixed planetary mass the astrometric signal falls inversely as the
Macroengineering in the Galactic Context: A New Agenda for Astrobiology
We consider the problem of detectability of macro-engineering projects over interstellar distances, in the context of Search for ExtraTerrestrial Intelligence (SETI). Freeman J. Dyson and his
