Science on the Ground Gives Clues to Planetary Formation

Astronomy is a science that is always associated with the sky, and rightly so.  But since the beginning of modern science there have been discoveries made on Earth that teach us about the formation and evolution of the Universe.  As telescopes become more powerful and allow us to look deeper into space, the technology to simulate outer-space conditions here on Earth has grown significantly.  In Albuquerque, New Mexico, a powerful tool called the Z machine generates quick high-energy pulses of electricity, which can be used to generate X-rays and Gamma rays to be used in experiments. Outside of astronomy, the...

Ancient Black Hole Larger than Current Theories can Handle

The thing about black holes is that they are very dense.  If we took the entire 2,000,000,000,000,000,000,000,000,000,000 Kg of the Sun (This is the real mass of the Sun) and turned it into a black hole, it would be about 6 Km in diameter. It is theorized that there are around 100 Million Black holes in the Milky Way Galaxy alone.  But if they aren’t near a large reservoir of gas and dust, with their small size they are pretty harmless and invisible.  The only way we could find them would be through their gravitational influence, which is hard to...

Hubble’s Best View of a Planetary Disk

At one point in history, let’s say around 1994, astronomers were fairly confident in their understanding of the formation of planetary systems.  Even though at the time we hadn’t found any planets orbiting other stars, they had long been theorized, and we figured that systems would form much like our own solar system.  Rocky planets in the interior, gaseous giants further out, and a huge icy debris field at the outer edges. And then along came 51 Pegasi b.  Half the mass of Jupiter, it orbits its star in only 4 days, far closer than Mercury.  It was considered a...

Rings around this Exoplanet put Saturn to Shame

Move over Saturn, J1407b has rings that are far more spectacular than anyone would have imagined.  This distant ‘planet’ (It may not actually be a planet) orbits an orange star 117 light-years away in the constellation Centaurus, and has a ring system consisting of 30 separate rings, each of which could be tens of Millions of Kilometres wide. In Spring of 2007, while monitoring the light from the star, astronomers noticed that the star was being eclipsed multiple times to varying degrees.  This led the team, consisting of astronomers from Leiden Observatory and the University of Rochester, to conclude that...
