Web3. It is possible that there could be planets where terrestrial-type life could survive orbiting a neutron star, but they are likely extremely rare and transient. The habitable zone where liquid water can persist around a star has a range ≈ 0.7 L ∗ to 1.4 L ∗ AU, where L ∗ is the luminosity of the star measured in solar luminosities. WebUnfortunately, the answer is yes. The sun, after all, is a star, and all stars will explode in due time, but fortunately, this won’t happen anytime soon, and definitely not in our lifetime. According to scientists, our Sun will only explode when it runs out of fuel in around 5 billion years, so it’s still a very very long time in the future.

WebWe'll say the sun and planets still exist, but for some reason no extrasolar stars can be seen from Earth. Let's say this is because our solar system is surrounded by a dark nebula. Nebulae are large clouds of dust and hot gas, and usually they're in the process of coalescing to form stars. Interstellar planets generate little heat and are not heated by a star. However, in 1998, David J. Stevenson theorized that some planet-sized objects adrift in interstellar space might sustain a thick atmosphere that would not freeze out. He proposed that these atmospheres would be preserved by the pressure-induced far-infrared radiation opacity of a thick hydrogen-containing atmosphere. razor with sharpener
