A staple of science fiction movies and stories for generations, traveling faster than light at more than 186,000 miles per second makes it relatively easy to go from one spot in the universe to another. Although it's fine for fiction, the fact isn't so...
How a neutron star is formed
By: Jose Juan Gutierrez
A neutron star is an extremely compressed star with high densities similar to those found in the nucleus of an atom. The densely, compacted neutron star could contain in its interior thousands of earth-like planets. The size of a neutron star is about the size...
Defining a neutron star
By: Jose Juan Gutierrez
A neutron star is the leftover of the gravitational collapse of a massive star. The collapse of this type of stars causes matter to acquire the density of the atomic nucleus. The density of a neutron star is so compacted that several thousand planets the...
How a pulsar is created
By: Jose Juan Gutierrez
A pulsar is a rapidly rotating neutron star whose magnetic fields emit charged particles of radiating energy. A pulsar possesses jets of particles streaming from their magnetic poles at the speed of light. These jets produce very intense beams of light. The magnetic and rotational...
The role of interstellar dust in the formation of stars
By: Jose Juan Gutierrez
The dark places between the stars or interstellar space are not empty spaces but filled with interstellar medium which is composed of gas and dust. Gas and dust are the raw materials from which stars are formed. The most abundant element in the interstellar medium...
Curiosity finds evidence water once existed on Mars
By: Kenneth Andrews
NASA's Curiosity Rover, the $2.5bn robot which was launched towards Mars in November 2011, has found clear evidence that at one point there was liquid running water on the surface of Mars. This discovery is a significant step towards ascertaining whether the Red Planet...

Many people share the fear that in years to come an Asteroid will collide with the planet and either end life as known or kill countless billions. The real concern however should be, if an asteroid was to have a trajectory leading to that of...
The formation of stars
By: Jose Juan Gutierrez
Star formation takes place within high molecular density clouds in the interstellar medium. The interstellar medium consists of particles of gas and dust of which 90% is hydrogen, 9 % helium and the remaining is traces of other elements. A molecular cloud will remain in...
How a neutron star is created
By: Jose Juan Gutierrez
A neutron star is created when a massive star collapses under its own gravity during the explosion of a supernova. A neutron star is the remnant of a high-mass star of about 5-10 solar masses, and is composed of neutrons. The size of a neutron...
Could anything be done to save Planet Earth if a large asteroid was heading this way?
By: Patrick Sills
What would happen if a significantly large asteroid was discovered to be on a collision course with the earth? If nothing could be done to stop it, the results would be devastating. In days of old, the disappearance of the dinosaurs was a mystery, but...
