Astronomers Expected More Tiny Worlds Beyond Neptune – Webb Found Something Else
This artist’s concept depicts a Trans-Neptunian Object (TNO), a small, faint, icy body orbiting the Sun beyond the…
People think Earth dies when the Sun becomes a red giant in five billion years — the more likely end is a billion years from now, when a star already 30 percent brighter than at birth pushes CO₂ too low for C3 plants, then a moist greenhouse strips the oceans of hydrogen and leaves a sterile Venus
The Sun is roughly 4.6 billion years old and about halfway through its main-sequence lifetime. The popular conception…
