So mankind is beginning to reach into space. In the past, our efforts beyond the Earth’s atmosphere have been purely strategic and political. Now, scientific advancement is becoming a priority for government agencies and business opportunities are beginning to show themselves for private enterprise. So what’s the next step? If we are to make the ultimate push into space and actually live out there, we must use any natural resource to our advantage. Strategically speaking, the Moon is an ideal stepping stone for mankind to spread our influence beyond Earth. So where do we start?
Having just completed my “Building a Base on the Moon” series on the Universe Today, it is evident that we are gradually developing the right technology and moving in the right direction. But we have a long way to go before we accomplish the ultimate lunar habitat… Continue reading “Building a Base on the Moon”
Lasers. Very cool and exciting toys. They have also revolutionized science and technology. Through a comparatively simple process, photons are bounced backward and forward within an optical cavity. Stimulated emission from the quantum states of the material within the cavity causes more and more photons to be generated. Eventually a threshold is reached and laser emission results, producing a collimated beam of a defined wavelength.
This week has been an exciting week for astronomers. The largest explosion ever seen in the Universe was observed on Wednesday. This gamma ray burst, produced when a star collapses in on itself to create a black hole, is a record breaker. Not only is it the biggest explosion mankind has seen since records began, it is also the furthest and oldest “thing” we have ever observed… Continue reading “Daily Roundup: The Mars Curse and the Biggest Explosion in the Universe!”
We know that dark matter is difficult to observe… in fact, we can only indirectly observe the stuff. Gravitational lensing and WMAP “Haze” are two possible ways to observe large-scale dark matter, but what about the small-scale stuff? New research suggests that some types of dark matter may be in the form of cold, primordial clumps of elementary particles and there’s a possibility we’ve been accidentally been observing them for years… Continue reading “Primordial Quark Nuggets Disguised as Near Earth Asteroids?”
The Earth’s Van Allen belts are the location for some of the most fearsome particles in space. Highly energetic particles from the Sun get trapped in the layers of the magnetosphere, setting them up for an injection of waves causing acceleration and heating. This naturally causes concern for astronauts and spacecraft passing out of the atmosphere and into this bubble of radiation only 200 miles above the surface. But spare a thought for any spacecraft passing through Jupiter’s magnetic field. The energetic particles there are far more powerful, plus one of the Jovian moons has a huge part to play, generating the plasma waves accelerating the particles even more… Continue reading “When a Moon Makes a World of a Difference”
There is a huge following of space blogs, like astroengine.com, following the developments of current space missions and new discoveries. Space blogs are different in that they present the news, but give a personal spin on what is going on. Far more exciting reading if you ask me, guaranteed to spark debate and awareness of mankind’s efforts in space…
