Our Satellite Tracking Tutorial also shows you just what the Chandra orbit looks like.Operating in space since 1999, Chandra detects and images X-ray sources that lie within our Solar System to those billions of light years away.Chandra's elliptical orbit takes the spacecraft to an altitude of approximately 139,000 km (86,500 mi) -- more than a third of the distance to the Moon.Find out the current position of Chandra in relation to the surface of the Earth from NASA/JPL's Eyes on the Solar System applet.The energy of the radiation depends on the distance between the crests (the highest points) of the waves, or the wavelength.In general the smaller the wavelength, the higher the energy of the radiation.Chandra has revealed how black holes impact their environments, how they behave, and their role in helping shape the evolution of the cosmos.More A supernova is the explosive death of a star, caused by the sudden onset of nuclear burning in a white dwarf star, or gravitational collapse of the core of massive star followed by a shock wave that disrupts the star.
Eventually, X-rays were found to be another form of light.
More Dark energy is a hypothetical form of energy that permeates all space and exerts a negative pressure that causes the universe to expand at an ever-increasing rate.
At the close of the 20th century, our perception of the Universe was jolted.
Light is the by-product of the constant jiggling, vibrating, hurly-burly of all matter.
More The word light usually makes one think of the colors of the rainbow or light from the Sun or a lamp.
