Meteorites play a role in ideas about how life on Earth began.
Here are three examples.
1. Panspermia is the theory that life exists throughout the Universe is transported by meteoroids, asteroids and planetoids from one region or galaxy to another.
2. The exogenesis theory is a more modest and conjectures that life on Earth was transferred from elsewhere, possibly via meteorite.
3. In 1996 a meteorite, ALH 84001, was conjectured to show fossil evidence of life on Mars. The meteorite was found on Earth after being knocked off Mars millions of years ago.
None of these theories or conjectures have been proven correct or even strongly possible. None have been proven wrong either.
What else can I help you with?
Is there another planet in outer space that's just like earth?
In life-wise terms, no.
How can a cosmic impact affect life on the earth?
A cosmic impact is an explosion that occurs in space when two objects collide. It is quite possible that asteroids and other debris in outer space would collide with each other from time to time.
A being thought to be from outer space?
There is currently no scientific evidence of any beings from outer space visiting Earth. While the possibility of extraterrestrial life exists, it has not been confirmed. Any claims of encounters with beings from outer space should be approached with skepticism until verifiable evidence is presented.
How do comets affect life on earth?
Exobiology speculates that microscopic life originated elsewhere and was brought here by a meteorite sent off by some violent distaster, which while it has not been proven is very scientifically plausible, as germs and viruses have proven to be able to survive in outer space and there is a gigantic gash on mars (a planet with water likely to have once supported life) which could have sent such a meteorite into outer space. Also, since comets are thought to be made substantially of water ice, it is theorized that they are the primary source of earth's water. It may seem unlikely, but in the early stages of earth's development there were probably many, many more comets than there are today, and it is not impossible that enough comets could have collided with earth over millions of years to supply us with our water.
Is space an ecosystem?
Space itself is not considered an ecosystem in the traditional sense, as it lacks the biological components and interactions that define ecosystems on Earth. However, environments like the International Space Station (ISS) can be viewed as micro-ecosystems, where human life and various organisms interact within a controlled environment. In this context, space can host ecosystems, but the vast expanse of outer space remains largely inhospitable and devoid of life as we know it.
Are there living things in outer space aside from earth?
As of now, there is no confirmed evidence of living things in outer space aside from Earth. Scientists continue to explore space for signs of extraterrestrial life, such as microbial organisms on other planets or moons.
Is there another planet in outer space that's just like earth?
In life-wise terms, no.
Has life been found yet in outer space?
No, so far we have found no life in outer space. Life may well exist in outer space, but we haven't found it yet.
What do astronauts do in outer space?
They study how long to get to planets and if there is life in outer space.
Study of life in outer space is known as?
Astronomy is the study of heavenly bodies.
Is outer space closer than deep space?
i honestly don't know if this is correct or not but i am pretty sure that outer space is space as a whole. they just called it outer because it surrounds the earth and goes around our spheres. deep space is further out in space. this is where most of the scientist go or want to go to find life or other interesting discoveries.
What is the mission of the spce probe in the outer space?
The mission of the space probe in outer space is to find out information about regions that are too far to see with telescopes. The space probe looks for life on other planets and weather conditions, asteroids, and other things that can affect the earth.
Why do you study outer space?
Studying outer space helps us understand the universe, the formation of stars and planets, and the possibility of life beyond Earth. It also contributes to technological advancements and inspires curiosity and wonder about our place in the cosmos.
Will people on earth ever find intelligent life in outer space?
maybe, well i heard there was life on mars...just maybe sorry idk no either
How can a cosmic impact affect life on the earth?
A cosmic impact is an explosion that occurs in space when two objects collide. It is quite possible that asteroids and other debris in outer space would collide with each other from time to time.
What do you send to outer space?
Various types of spacecraft and satellites are sent to outer space, including probes, telescopes, and rovers. These objects are designed to study celestial bodies, conduct scientific research, and explore outer space. Additionally, signals and messages have been sent from Earth as a form of communication with potential extraterrestrial life.
What is the the main energy source for life on earth?
Sunlight is the main energy source for life on earth.
