The Milky Way in a Diagram

Home galaxy of Earth, the Milky way is a spiral – shaped system of a few hundred billion stars. Bright regions of recently formed stars highlight its arms, while older stars explode or expel their outer layers as beautiful planetary nebulae, then fade away and die. A thick swarm of orange and red stars marks the galactic bulge, encapsulating the star-packed galactic center.

Messages Sent into Space
Space messages tell about the biosphere, that includes the basic chemical compositions of the continents, oceans and atmosphere. The highest and lowest points of Earth and the surface strength of gravity are also listed in the space messages. Along with the relative sizes and ordering of the planets in our solar system, this message tells about the mass and radius of both our Sun and Jupiter. ...
Is There an Edge of the Universe?
The “dark flow” of wayward galaxy clusters that appear to be pulled in one direction could give us our first hint of something beyond the cosmic horizon, which normally marks the limit of the observable universe.
List of All Space Missions to Different Planets and Beyond
Space examination or the Space missions is the disclosure and examination of space by system for space mechanics. Physical examination of space is administered both by human spaceflights and by robotic shuttle. While the observation of articles in space, rumoured to be Astro science, starts before reliable recorded history, it was the development of unbelievable and similarly profit...
Driving Force That Drives Galaxies Apart
The universe is expanding at an ever – increasing rate, with something that astronomers call dark energy appearing to push it apart faster than gravity can pull it together. Type la supernovas are stars that explodes with a predictable brightness. Light from distant supernovas locks dimmer and redder than expected, implying that the universe is expanding. The more distant the star, the fast...
Black Holes Explained
The most Bizarre objects in the Universe, black holes are aptly named – they emit no visible light at all. And yet, most black holes are the end state of the most brilliant objects in the cosmos; giant stars that go supernova. The super compressed core that remains after the explosion has such strong gravity that even light cannot escape it – so the object is black.
Dwarf Planets Explained
After Pluto was discovered in 1930, it was regarded as the ninth major planet, although it was soon found to be very different from the others. It is smaller than Earth’s Moon and follows an elongated, titled orbit. In the 1990’s astronomers began to discover small bodies similar to Pluto beyond Neptune. Some, such as Eris, were larger then Pluto. In 2006, astronomers decided to define a ne...
The Space Capsule
The Space Capsule has been developed for NASA to service the International space station; the reusable Dragon capsule is lofted into orbit by Spacex’s Falcon 9 rocket. While the first flights are to carry cargo only, the capsule was designed to be capable of carrying up to seven astronauts.
Apollo Lunar Module Initial Landing Component
Majority of the Apollo Lunar Components are more sensitive and they have to be treated very carefully. It contains components like Rendezvous radar antenna, environmental Control System module, Crew Compartment. A crewman handles all these components with utmost care. Reaction Control thruster assembly, ascent propulsion, Red Docking Light, Egress Platform, Fuel tank, Descent Engine, Lunar Sur...
Debris That Hit Space Shuttles
There are many impacts of the Space Shuttle. Atlantis struck by debris from the nose cone of a solid rocket booster 85 seconds after liftoff causing 707 dents, 298 larger than one inch in diameter. Columbia Foam debris from the external tank causes more than 100 dents and spurs NASA to begin a program to resolve foam-shedding.
Fun Facts About the Space Shuttle
Finding out the length of an orbit is a very tedious task. Unless one have flown aboard the space shuttle or have seen it in person, it can be difficult to mentally visualize the size of the vehicle. Here, we measure the orbiter against a familiar object, a school bus. The weight of Orbiter would weight around 178000 pounds. The heaviest African Elephant weighs 13200 pounds. It would take appro...
A Brief History of the Solar System
The process of existence or initiative of life in the Solar System looks very interesting. Life in the solar system is a monomeric nucleotide, pretty much just a simple molecular compound made out of a normal, every-day inorganic material. Life started in the Earth once the things inside it are cooled down a bit. Basically life in the Earth is a replicator, the way it just happened or formed. Life...
National Geographic: Mars
Scratches is presently accommodate to five working shuttle: several in circle—the Scratches Odyssey, Scratches Express, and Scratches Surveillance Orbiter; and two on the surface—Scratches Investigation Wanderer Opening and the Scratches Science Research facility Interest. Old space apparatus on the surface incorporate MER-A Spirit, and a few different idle landers and meanderers, both on trac...
Diagram of the Space Station Life Support System
This diagram shows how astronauts live on the space station. Everything is attempted to be recovered on the space station. The urine that astronauts dispense from their bodies is reused as water. Waste water is then reused to create oxygen. Co2 is removed through overboard venting. It's amazing how much everything is reused on board.
Diagram of the Space Shuttle Carrier
The Space shuttle bearer or the transporter flies return flights for the most part leave at day break or right away thereafter. Flying in the ballpark of 50 miles in front of it could be a pathfinder plane checking for climate unsettling influences and rerouteing the shuttle transporter if essential. In the ballpark of 30 group parts fly with the pathfinder and examine the shuttle for ha...
50 Years of Spaceflight -- Capsles and Shuttles
It has been 50 years since the Russian pilot Yuri Gagarin has stepped onto the Moon in 1961. Since then more than 500 people have been launched into space in a variety of vessels. Twelve people have walked on the moon, and an additional 14 have flown over the moon without landing. The farthest away that humans have traveled so far was 248655 mi, which was achieved by the Apollo 13 astronauts ...
Constellation's Components
The Constellation space transportation system will be able to carry out multiple tasks, space station resupply and moon missions, among others – using some shared and minimally modified elements, TO reduce risks and save costs, many of the components were based on existing technologies.  
Variable Stars and What They are
These maps show stars visible all year in the northern and southern hemispheres. They also mark the position of interesting objects, such as star clusters and galaxies. To see what is visible, face north in the northern hemisphere and south in the southern hemisphere. The Variable stars contains pulsating variables, the eclipsing variables and the rotating variables. Toward the end of their...
Comet Explanation
Astronomers expect spectacular displays of meteor showers over North America and Europe on Wednesday and Thursday as the Earth crosses the path of Comet Swift-Tuttle’s Orbit. The comet you see from your eye is actually the icy dust from the comet burning off as it nears our Sun.
