NASA Concept – Asteroid Survey

The NASA Innovative Advanced Concepts (NIAC) program promotes ideas to innovate aerospace. One of the proposals currently being studied by NIAC involves a survey of asteroids. NASA 360 Presents – From Science Fiction to Science Fact – [youtube.com] Is suspended animation possible? Can we 3D print whole structures on the moon? How about swimming the […]

GAIA Space Observatory Searches for New Asteroids

The GAIA space observatory platform was launched in 2013 into a stable Lagrange orbital point known as L-2. L-1 is a stable point on the Sun side of Earth and L-2 is a mirror of that but on the opposite side of Earth from the Sun. GAIA is a project of the European Space Agency […]

A Huge New Space Telescope

The Hubble space telescope opened the universe to new levels for our viewing. After twenty years of effort, a replacement for the Hubble, called the James Webb Space Telescope is nearly ready to go. It will be one hundred times more powerful. Into the Unknown – [youtube.com] Into the Unknown tells the story of the […]

1635 – Robert Hooke – bio

Robert Hooke was born in 1635 on the Isle of Wight in England. He was known as an architect and philosopher, but made contributions in many fields. He discovered Hookes Law of elasticity which describes the compression and extension of springs. He collected observations made with magnifying lenses, of both small objects and distant objects, […]

History of the Telescope

Amazing History of the Telescope – [youtube.com] 1608 – telescope – [hackingtheuniverse.com] Hans Lippershey, a Dutch lensmaker has been given primary credit for making the first […]

-3500 – glass

Naturally occurring volcanic glass (obsidian) was use before we learned to make glass around -3,500 in Egypt and Mesopotamia. The earliest form of glass made by humans was probably glazes that were used on ceramic pots. By mixing crushed quartz with calcite (calcium carbonate) from limestone, a solution is produced which can be fired into […]

Galactic Communications Using a Gravitational Lens

Gravitational lensing is the process of a large mass bending light from a distant source. Einstein predicted this and astronomers can now detect it. By placing an optical collector or a radio antenna at a distance of 550 AUs or greater from our Sun, it can be used as a lens to focus detail from […]

Extremely Large Telescope

Construction on the European Extremely Large Telescope (E-ELT) is scheduled to begin in 2012. The E-ELT will be built at Cerro Armazones in northern Chile and will have a primary mirror that is almost 40 meters across. The European Extremely Large Telescope – [eso.org] Extremely Large Telescopes are considered worldwide as one of the highest […]

1738 – Herschel – bio

Frederick William Herschel was born in 1738 in Hanover, Germany and was an astronomer and musician. He built over four hundred telescopes, including one that had a 40 foot focal length and 50 inch mirror. He observed and catalogued over 2400 astronomical objects. He discovered Uranus, two of it’s moons and two moons of Saturn. […]

1629 – Huygens – bio

Christiaan Huygens was born in 1629 in The Hague, Netherlands (then known as the Dutch Republic) and was an astronomer, mathematician and physicist. He advanced the art of grinding lenses and building telescopes and in 1655 discovered that Titan was a moon of Saturn and in the next year became the first to propose that […]
