Can there be life on stars?

Some stars do have excess cooling, but you don't need cosmic strings, monopoles, and nuclear life to explain it. Right now, there's no evidence to support nuclear life, but studies like this can help us think outside the box of terrestrial life.

Is life possible on the sun?

The Sun could not harbor life as we know it because of its extreme temperatures and radiation. Yet life on Earth is only possible because of the Sun's light and energy.

Can there be life without a star?

Scientists think planets that don't orbit any star, called free-floating planets or rogue planets, can harbor life too. These planets originally form around stars like any other but get kicked out of their system at some point due to gravitational effects of giant planets within.

How do stars come to life?

Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.

Have we ever witnessed a star being born?

Summary: Astronomers have glimpsed what could be the youngest known star at the very moment it is being born. Not yet fully developed into a true star, the object is in the earliest stages of star formation and has just begun pulling in matter from a surrounding envelope of gas and dust.

Could Life Evolve Inside Stars?

How long do stars live for?

Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years.

On which planet life is possible?

Among the stunning variety of worlds in our solar system, only Earth is known to host life.

Can moon be habitable?

Bottom line: The moon is airless and mostly dry now, but has water ice deposits in shadowed craters at its poles and below its surface. New research suggests more water on the moon billions of years ago and a possibly habitable moon, capable of supporting simple life forms, at that time.

Which planet could support life?

Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.

What year will Earth be uninhabitable?

This is expected to occur between 1.5 and 4.5 billion years from now. A high obliquity would probably result in dramatic changes in the climate and may destroy the planet's habitability.

Is there life on Jupiter?

Jupiter's environment is probably not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.

What planet rains diamonds?

Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.

Is Earth the only planet with life?

Earth is the only planet in the universe known to possess life. The planet boasts several million described species, living in habitats ranging from the bottom of the deepest ocean to a few miles up into the atmosphere. Researchers think far more species remain that have yet to be described to science.

Can humans live on Europa?

Europa's surface is blasted by radiation from Jupiter. That's a bad thing for life on the surface – it couldn't survive. But the radiation may create fuel for life in an ocean below the surface. The radiation splits apart water molecules (H2O, made of oxygen and hydrogen) in Europa's extremely tenuous atmosphere.

Is Saturn habitable?

Saturn's environment is not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.

Can you breathe in Europa?

Europa has a thin oxygen atmosphere, but it is far too tenuous for humans to breathe. From the surface of Europa, Jupiter appears 24 times larger than the moon appears in our sky. Europa's magnetic field shields its surface from Jupiter's deadly radiation.

Did Venus ever have life?

The possibility of life on Venus is a subject of interest in astrobiology due to Venus's proximity and similarities to Earth. To date, no definitive evidence has been found of past or present life there.

What if Venus had a moon?

If Earth had been orbited by a low flying potato shaped body, things would have been quite different. If Venus had a moon, we should suppose the system would look a lot like the Earth - Moon system : so close to the sun, it would be unlikely to have a moon forming far from the planet like in the outer solar system.

Are there humans in other galaxies?

Unfortunately, we're unlikely to ever make contact with life in other galaxies. Travel by spaceship to our closest intergalactic neighbor, the Canis Major Dwarf, would take almost 750,000,000 years with current technology.

Can a star turn into a planet?

Yes, a star can turn into a planet, but this transformation only happens for a very particular type of star known as a brown dwarf. Some scientists do not consider brown dwarfs to be true stars because they do not have enough mass to ignite the nuclear fusion of ordinary hydrogen.

Do Dead stars still shine?

After a star dies, there is still some residual heat left over. That heat makes the star (white dwarf or neutron star) glow, even though it is not producing any energy. Eventually, the star cools off and does indeed simply become a hunk of ash, which we call a "black dwarf."

Will our Sun become a black hole?

Will the Sun become a black hole? No, it's too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole.

Can you own a planet?

No, people cannot legally buy planets, at least for now. There isn't any way to legally enforce a claim to a planet, and courts have rejected similar claims in the past. International law forbids countries from claiming any celestial body, meaning a nation cannot grant space real estate to its citizens.
