In the background for my book, I'm looking for an alternative way for space travel. What I'm currently considering: A starship travels to the center of a star by using the natural downwards flows t...
I am writing a book where there is a binary system with a red and blue star. There is planet with the same properties as earth orbiting in a habitable zone around the 2 stars. The question How c...
I'm thinking a quadruple stars system where a binary star system orbits another but more massive binary star system is probably fine, however so far I never encounter binary planets orbiting triple...
So, I'm writing a set of short stories (i.e. in the "Martian Chronicles" format). It was going to be centered around life on Earth through the sudden dissapearance of the Sun, but after surprinsing...
So having read a couple of other questions on here, and postulating over this for a while, here's my question. Is it possible to have two magnetars in a distant binary orbit, with an earthlike pla...
The errant planet is similar in size with the star and it's made all of water. Usually is icy, but probably gonna melt when approach the star. What happens during the process of collision between ...
Every day the Sun is closer to be a Red giant, making the live of the initial home of the humanity practically uninhabitable. Humans are not there anymore. It's a protected territory, but the Sun g...
I wonder if there is a stable star-moon-planet system where a specific area of the planet would be permanently covered by shadow. I'm not looking for a common tidally locked planet with a roughly 5...
Assuming in a galaxy far far away there is a Type 2 civilization (currently on the verge of making the transition to Type 3). Their scientists predicted that the star (red giant) they are orbiting...
I'm going for the ultimate in world building here: Creating a whole new star. I have a race that's about a Type II civilization (as per the Kardashev scale). The important thing here is that they'...
There is an intergalactic war going on in the Milky Way, to get more resources. My company have been called upon to mine nebulae. There is no nebulae in the vicinity but I have got a few high mass ...
By Mars sized I mean with masses between 0.10 (M⊕) and 0.25 (M⊕), the planets need to have independent orbits around the star. We can assume the habitable zone stretches from 0.70 AU, to 1.5 A...
The binary stars system is comprises of a red giant with 6 solar masses and a Sun-like star, the exoplanet is orbiting in the Goldilock's zone with a molten iron core which generate a magnetic fiel...
I suppose there is sufficient time for us to achieve type 2 civ status on the Kardashev scale, that means we cannibalise the Sun! Joke aside would such a civilization level be sufficient to revert ...
Assume the planet's orbit around Sirius B is much closer to its parent star than we are to the sun so it still receives enough light and heat to form an Earth-like environment. What does night look...
As the title says, what if a neutron star stops spinning what will happen to the materials that the neutron star is made of? Will they still be super dense? Are they brittle? If they are, how st...
You're the head engineer for an advanced civilization. Humanity has long since spanned the stars, as as vast as her civilization has become her need for power has increased exponentially. To feed t...
I have a binary system in which my world orbits one of the stars, not the pair, in the habitable zone. The stars are relatively close together (because I want the secondary one to shed significant...
Consider an Earth like planet is orbiting around a Sun like star, it is almost identical to our Solar system, except the orbital inclination of the planet is 90 degree to the equator of the star (n...
In Halo series there is an intelligent race called Unggoy that evolved on a planet caled Balaho orbiting a blue supergiant called Tala, I would like to know if it would be possible for an intellige...
I hope this is the right Stack exchange for this question. I'm designing a planet as a setting for a tabletop RPG campaign, and basically I'm looking for some help to make sure my idea is at least ...
Globular clusters are old, dense groups of stars that tend to have relatively few metals (in this case meaning any elements heavier than helium). Clusters near the galactic core tend to have more m...
Since the Sun is the only star we know to have life in its planetary system, I came to wonder about if it was replaced by, say, VY Canis Majoris How far would we have to be so that we would still b...
Is it possible for a earth-like planet to orbit a neutron star & have intelligent life-forms, even if said neutron star 'moves' through different galaxies? as seen in this video - https://www....
Earth, present time or very near future. Astronomers have just announced that it is believed that almost 9 billion habitable Earth-like planets exist in the Milky Way alone (this is true, but there...
I've come up with a couple of exoplanets for a story, and have reached the limits of my knowledge. I've googled around, and I had a space enthusiast friend look at them, but he freely admits that h...

I'm trying to come up with a scenario involving a mining base built on a planet that may only be approached from the shadowed side; the star (or other body) allows only that narrow lane of approach...
Suppose a planetary system works in such a way that there is a rotating planet in the direct centre of a binary star (the star system's centre of gravity, also known as barycenter), such that the t...
I am working on a novel of a fantasy world on another planet. I am not too concerned with scientific accuracy, as again, it's fantasy, but I am not interested in supernatural things for my world. T...
Essentially, two stars of identical mass but different temperatures are in a binary system. One planet is directly in their barycenter, tidally locked to one and therefore both stars. The effect I'...
I have an idea for a planet that orbits two stars. These starsslowly orbit each other, have equivalent masses/sizes, and while one is slightly red, the other is slightly blue. When I talk about the...
Stars and constellations have been for many civilizations,sources of wonder and mystery. We look at the stars so much, that we found patterns and shapes in the stars, and used them as guidance duri...
I am creating a hypothetical race of aliens native to a planet orbiting an F class star; the mass of the star is 1.50 (M☉). Would this star live long enough to allow the evolution of intelligent ...
So your star and/or planet gets hit by the CrushSun. The huge laser looks terrifying, but then you realize that the main weapon is the microblack hole it hit you with. What does it look like when ...
In a world I'm currently building, I've devised a magical creature that sustains, indefinitely, a Class O hypergiant star. This, of course, violates conservation of mass and conservation of energy....
The Halo video game's extended universe book Halo: Evolutions describes the Battle of Psi Serpentis, in which a superjovian planet is converted into a brown dwarf via massive nuclear bombardment of...
A neutron star is a type of compact star that can result from the gravitational collapse of a massive star after a supernova. Neutron stars are the densest and smallest stars known to exist in t...
Imagine a dwarf star and a gas giant orbiting each other around their barycenter. The gas giant does not have enough mass to ignite (but may be close to igniting). Over time, the sun loses mass du...
Is there any way to make a planet with a corkscrew orbit (like this) that could host a sci-fi civilisation? It'd be amazing if there was a way to make life arise naturally, but colonize-able works...
In this scenario, the sun is a binary star, sharing orbit with an F-type main-sequence star. The first planet from that binary star is a Jupiter-like gas giant, orbiting one-third of an AU from th...
In this hypothetical solar system the one habitable planet in question would be at center of two sun stars, one similar to our sun and the other a red dwarf. What kind of effect would this have on ...
Would it be in ANY way possible to have 3 or more stars within a few light-hours (up to several light-days between the most distant stars) of each other, and for the resulting orbital mash-up to al...
Let's say my terrestrial planet has a stable circumbinary orbit around two suns similar to the Kepler-47 system, in the habitable zone, with an orbit similar to Kepler-47c. The challenge here is th...
I'd like to be able to see from my Earth-like planet, a very bright nebula that can even be seen during the daytime. I question, however, whether that is possible, because in order for it to be co...
An x-ray binary is a binary star system consisting of a star and a stellar remnant. As matter is ripped from the star and is then accelerated into the neutron star/black hole by its gravity, x-ray...
Consideration For the sake of argument, please assume the following: The planet in question is around the size of Earth The planet may contain native intelligent life, artificially engineered Th...
After writing this question, I came up with a new question. Consideration The considerations are mostly similar to the linked question (reading it is highly encouraged, as I am trying to post as...
My story revolves around a star going supernova. The 'Earth' in this story is about 100 light-years or more away (a safe distance, but not too far away). I need this supernova to somehow accelerate...
