Our Sun: Facts

From our vantage point on Earth, the Sun may appear like an unchanging source of light and heat in the sky. But the Sun is a dynamic star, constantly changing and sending energy out into space. The science of studying the Sun and its influence throughout the solar system is called heliophysics. The Sun is []

Learn About the Universe With the James Webb Space Telescope

NASA is launching the largest, most powerful space telescope ever. The James Webb Space Telescope will look back at some of the earliest stages of the universe, gather views of early star and galaxy formation, and provide insights into the formation of planetary systems, including our own solar system.

Solar System Facts

Our solar system includes the Sun, eight planets, five officially named dwarf planets, and hundreds of moons, and thousands of asteroids and comets. Our solar system is located in the Milky Way, a barred spiral galaxy with two major

Galaxies

Galaxies consist of stars, planets, and vast clouds of gas and dust, all bound together by gravity. The largest contain trillions of stars and can be more than a million light-years across. The smallest can contain a few thousand stars and span just a few hundred light-years. Most large galaxies have supermassive black holes at []

How Many Solar Panels Do I Need To Power a House?

If you have limited roof space, you may consider a higher power rating to use less panels. If you want to spend less per panel, you may consider a lower wattage. Yes, in many cases a 10 kW solar system is more than enough to power a house. The average US household uses around 30 kWh of electricity per day, which would require 5 kW to 8.5 kW

How Many Solar Systems Are in Our Galaxy?

Our solar system is just one specific planetary system—a star with planets orbiting around it. The James Webb Space Telescope, set to launch in 2021, will also observe many of the exoplanets we have discovered and help scientists reveal details about these distant worlds.

Milky Way

The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy''s appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.. The Milky Way is a barred spiral galaxy with a D 25 isophotal diameter estimated at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years),

Cosmic Distances

Light years also provide some helpful perspective on solar system distances: the Sun is about 8 light minutes from Earth. (And yes, there are also light seconds!)And because light from objects travels at light speed, when you see the Sun, or Jupiter or a distant star, you''re seeing it as it was when the light left it, be that 8 minutes, tens of minutes or 4.3 years ago.

Moons of Our Solar System

How Many Moons Are in Our Solar System? Naturally-formed bodies that orbit planets are called moons, or planetary satellites. The best-known planetary satellite is, of course, Earth''s Moon. Since it was named before we learned about other planetary satellites, it is called simply "Moon." According to the NASA/JPL Solar System Dynamics team, the current tally []

10 Questions You Might Have About Black Holes

A black hole is an extremely dense object in space from which no light can escape. While black holes are mysterious and exotic, they are also a key consequence of how gravity works: When a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity

Solar System

Solar System. What is a solar system? A solar system is essentially a star orbited by one or more planets bound to it by its gravitational pull. Our solar system is home to eight planets, several dwarf planets, over 200 moons, countless asteroids, comets, meteors, and other forms of planetary debris. For most of history, it was believed that

OverviewFormation and evolutionGeneral characteristicsSunInner Solar SystemOuter Solar SystemTrans-Neptunian regionMiscellaneous populations

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers

Planetary Systems

Planetary Systems Our solar system consists of the Sun, whose gravity keeps everything from flying apart, eight planets, hundreds of moons, and billions of smaller bodies – from comets and asteroids to meteoroids and tiny bits of ice and rock. Similarly, exoplanetary systems are groups of non-stellar objects circling stars other than the Sun, and []

Space-Based Solar Power

Capturing solar power in space for use as energy on Earth seems farfetched. But recent developments could make this a reality in coming years.

Science 101: The Solar System

Transcript (English) - [Narrator] Our solar system is one of over 500 known solar systems in the entire Milky Way galaxy. The solar system came into being about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed, resulting in a solar nebula, a swirling disc of material that collided to form the solar system.
