Radio Astronomy

Radio waves are the same type of waves as light. They have less energy than visible light and so have a longer wavelength, but they travel at the same speed as light.

At night our eyes and optical telescopes sees light from stars. But normal stars only produce radio waves very weakly.

The Sonoma State University NASA Education and Public Outreach group, in collaboration with several other people, has created a series of formal and informal education and outreach products based on the science of black holes. The formal products – which include an educator’s guide with activities and in online resource are closely tied to the informal products, which include a planetarium show, a...
Saturn V Apollo Flight Configuration
The Saturn V (declared "Saturn Five") was an American human-appraised expendable rocket utilized by NASA's Apollo and Skylab systems from 1967 until 1973. A multistage fluid-energized start vehicle, NASA started 13 Saturn Vs from the Kennedy Space Focus, Florida with no misfortune of group or payload. It remains the tallest, heaviest, and by and large weighty rocket ever carried to operatio...
Viewing the Past in Space
The ancients had it wrong: the Earth is not the center of the universe. But the Earths is at the center of the part of the Universe that we can see. A being on a planet orbiting, say, a star in the galaxy M87 would see a different part of the Universe, one centered on him.
NASA's Future Capsule
NASA has decided that the MPCV, or Multi-purpose Crew Vehicle, will be America’s next crewed spacecraft following the retirement of the space shuttle. The MPCV program is a refocus of the Orion Crew Vehicle Program, which has been in development since 2005.
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.
Big Bang in a Diagram
Electrons join with protons and neutrons to structure molecules, generally hydrogen and helium. Light can at last sparkle. Gravity makes hydrogen and helium gas blends to shape the goliath mists that will come to be cosmic systems; more modest bunches of gas downfall to structure the first stars.  As galaxies cluster together under gravity, the first stars die and spew heavy elements into spa...
List of All the Missions to Mars to Date
Some of the Missions that have been flown to Mars are Mariner 4, Mars 3, Mars 5, Mars 6, Phobos 2, Mars Express, Dawn. Many have been successfully sent to the Mars and some of them with partial success.It's interesting to see the trend that trips to Mars have taken. Particularly how the USSR sent many probes to Mars before the USA, but the USA had the first successful mission. Check out the other...
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...
Saturn Explained: Inside and Out
Saturn is the sixth planet from the Sun and the second vastest planet in the Earth's planetary group, following Jupiter. Named following the Roman god Saturn, its galactic image (♄) speaks for the god's sickle. Saturn is a gas goliath with a normal span something like nine times that of Earth.[12][13] While a single-eighth the middle thickness of Earth, with its more substantial volume Saturn ...

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.

Explaining Gravitational Lensing
Light always leaves from a young, star forming blue galaxy near the edge of the visible universe. Some of the light passes through a large cluster of galaxies and surrounding dark matter, directly in the line of sight between earth and the distant galaxy. The dark matter’s gravity acts like a lens, bending the incoming light.  
Other Solar Systems
Is our Solar system unique in the Universe ? Until recently, astronomers could only guess whether other stars are orbited by planetary systems. Extrasolar planets – those that orbit stars other than the Sun – are difficult to detect, because they are about one – billionth the brightness of their parent stars. Extrasolar planets can also be detected by watching for a drop in brightness as ...

A decade of intense space activity followed as Russian and American probes, robots, and crewed craft were sent to investigate and land on the l...
