Do Aliens Exist? We Asked a NASA Scientist: Episode 5

We have not yet discovered life on any other planet, and we have not seen any scientifically supported evidence for extraterrestrial life. But if we think about life on this planet, beyond the big things — the elephants, the whales, redwoods trees –– and focus on the tiny things, nearly everywhere on Earth that we''ve looked, we''ve

Where Do Chemical Elements Come From?

mately end up in planets like Earth, being part of everything we see around us and ourselves. The carbon in our cells, the oxygen in the air, the silicon in rocks, and just about every element, were all forged inside ancient stars before being strewn across the universe when the stars exploded. during the past century, scientists have

Formation and evolution of the Solar System

Artist''s conception of a protoplanetary disk. There is evidence that the formation of the Solar System began about 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. [1] Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other

Where Do Planets Come From?

The StoryBots arrive in outer space to learn where planets come from. They visit each planet in our solar system, but none of them are able to answer the question of how planets are formed. Finally they meet Pluto, a disgruntled former planet who''s determined to be classified as a planet again. He tells them they''ll have to go deeper into

Where Do Moons Come From? We Asked a NASA Scientist:

For the last common way moons are thought to originate, we have to look at Neptune''s largest moon, Triton. This moon has a very strange orbit, which led us to hypothesize that it was actually a dwarf planet from the Kuiper Belt, just like Pluto. One day it got too close to Neptune and was captured by Neptune''s gravity. So where do moons

How do planets and stars form?

There are at least 200 thousand million stars in our Milky Way (of which the Sun is just one) and probably most of them (if not all) have planetary systems with planets orbiting around their parent stars. We see that gravitational contraction of matter in the space between stars plays a central role in the formation of both stars and planets.

How do stars and planets form and evolve?

Most of those identifications have come thanks to one observatory: NASA''s Kepler space telescope. Until it lost its ability to point, Kepler observed a region of the sky containing about 150,000 stars with potential planets, monitoring them for the slight decrease in light caused by planets crossing in front of the star.

Formation and evolution of the Solar System

OverviewFormationHistorySubsequent evolutionMoonsFutureGalactic interactionChronology

The nebular hypothesis says that the Solar System formed from the gravitational collapse of a fragment of a giant molecular cloud, most likely at the edge of a Wolf-Rayet bubble. The cloud was about 20 parsecs (65 light years) across, while the fragments were roughly 1 parsec (three and a quarter light-years) across. The further collapse of the fragments led to the formation of dense cor

in part of the song, "When giant clouds of dust and gas collapse, a star is born, and from the leftovers bits of dust and gas, new planets often form" how many planets went around instead of 8 3 1

How Did the Solar System Form?

4 days ago· The solar system is a pretty busy place. It''s got all kinds of planets, moons, asteroids, and comets zipping around our Sun. But how did this busy stellar neighborhood come to be? Our story starts about 4.6 billion years ago, with a wispy cloud of stellar dust. This cloud was part of a bigger cloud called a nebula.

Explain This! How Do Planets Form?

Planets form around young stars, and young stars form out of clouds of gas and space dust known as protoplanetary disks; some of the rocks in our solar system''s main asteroid belt contain evidence of these disks—which

1.2. How did our Solar System form? | Astrobiology Learning

3 days ago· These were young planets, and eventually, over a long time and through many, many collisions, our eight planets were formed – Mercury, Venus, Earth, Mars, Jupiter, Saturn,

Ask The Storybots (S03: Where Do Planets Come From?)

This was a very unique sequence to work on. We wanted to make the planets forming using stopmotion, but the sheer amount of animation, shooting, and compositing that would be needed would have been too much of a strain on our 2-man stopmotion team. We ended up developing a look that captured the "feel" of stopmotion, while also allowing for the aesthetic advantages

How Did the Planets Get Their Names?

Instead, seeing the new planet''s blue tint, astronomers named it Neptune after the Roman god of the sea. Back when there was a ninth planet, Pluto was named for the Roman god of the underworld. This was fitting. The former planet is the farthest world from the Sun. Today, Pluto is called a dwarf planet. Who gets to name the planets now?

What are comets and where do they come from?

These systems display tremendous diversity, with many planets occupying strange orbits that were difficult to reconcile with the conventional wisdom of the early 1990s for how our solar system

Where do Rogue Planets come from? | ScienceBlogs

A recent simulation shows that for every planet-rich solar system like our own (with gas giants) that forms, there''s likely to be at least one gas giant planet that gets kicked out, into the

How Do Planets Get Their Names? We Asked a NASA Scientist:

If we keep on going outward, we have three more things that historically have been called planets. You have Uranus, Neptune and Pluto. These are Greek or Roman names. These planets weren''t seen by the Greeks or Romans, but because the discoverers wanted their planets to fit in with the existing theme of the mythology of the existing planets.

Explain This! How Do Planets Form?

So then the moons for the terrestrial planets have to come from somewhere. So either they''re captured—like, we think Mars captured its moons from the asteroid belt—or there was some kind of collision that led to the creation of the moon, like we think for our own moon.
