Milky Way – Exoplanet Exploration: Planets Beyond our Solar

Our galaxy, the Milky Way, is typical: it has hundreds of billions of stars, enough gas and dust to make billions more stars, and at least ten times as much dark matter as all the stars and gas put together. In a system with two known planets, astronomers spotted something new: a small object transiting across the Sun-sized star. This

They come in a variety of shapes and sizes. The Milky Way is a large barred spiral galaxy. All the stars we see in the night sky are in our own Milky Way Galaxy.

The Milky Way Galaxy

The annotated artist''s concept illustrates the new view of the Milky Way. The galaxy''s two major arms (Scutum-Centaurus and Perseus) can be seen attached to the ends of a thick central bar, while the two now-demoted minor arms (Norma and Sagittarius) are less distinct and located between the major arms.

First Evidence of a Planet Identified Beyond Our Galaxy

An artist''s rendering of the first planet candidate identified outside of our Milky Way galaxy is pictured next the M51 galaxy. A composite image of M51 with X-rays from Chandra and optical light from NASA''s Hubble Space Telescope contains a box that marks the location of the possible planet candidate.

What Is a Galaxy? | NASA Space Place – NASA Science for Kids

It''s a small part of the Milky Way Galaxy. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems. A galaxy is held together by gravity. Our galaxy, the Milky Way, also has a supermassive black hole in the middle. When you look up at stars in the night sky, you''re seeing other stars in the Milky Way.

Kepler / K2

The Kepler space telescope was NASA''s first planet-hunting mission, assigned to search a portion of the Milky Way galaxy for Earth-sized planets orbiting stars outside our solar system. During nine years in deep space Kepler, and its second act, the extended mission dubbed K2, showed our galaxy contains billions of hidden "exoplanets," many of which could be promising

This artist''s illustration gives an impression of how common planets are around the stars in the Milky Way. The planets, their orbits and their host stars are all vastly magnified compared to their real separations. A rough estimate from this survey would point to the existence of more than 10 billion terrestrial planets across our galaxy

In Depth | Our Solar System – NASA Solar System Exploration

Introduction. The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids.

OverviewContentsEtymology and mythologyAppearanceAstronomical historyAstrographySize and massStructure

The Milky Way contains between 100 and 400 billion stars and at least that many planets. An exact figure would depend on counting the number of very-low-mass stars, which are difficult to detect, especially at distances of more than 300 ly (90 pc) from the Sun. As a comparison, the neighboring Andromeda Galaxy contains an estimated one trillion (10 ) stars. The Milky Way may contain ten billion white dwarfs, a billion neutron stars, and a hundred million stellar black holes.
