In commemoration of the 15th anniversary of NASA's Chandra X-ray Observatory, four newly processed images of supernova remnants dramatically illustrate Chandra's unique ability to explore high-energy processes in the cosmos. The images of the Tycho and G292.0+1.8 supernova remnants show how Chandra can trace the expanding debris of an exploded star and the associated shock waves that rumble through interstellar space at speeds of millions of miles per hour. The images of the Crab Nebula and 3C58 show how extremely dense, rapidly rotating neutron stars produced when a massive star explodes can create clouds of high-energy particles light years across that glow brightly in X-rays.

Crab Nebula, which gets its name from the shape, are the remains of a supernova that has become a pulsar that, with patience, you can see in the center of […]


Three of the many satellites of Jupiter (there are some 60-odd numbered) in a photo taken by the Hubble: Io, Europa and Callisto. The curious thing about this picture is […]

Even if you do not believe it, see the Milky Way, our galaxy, or at least a part of it, it is very simple. What you will see, depending on […]


The cosmic dance of two black holes, that’s exactly the image you see. Obviously, a black hole is not seen as not reflecting light (we were all down except radiation […]


Kepler-452b, the “biggest” Earth brother. NASA has identified the planet “more similar” to our Earth thanks to the Kepler telescope. That yes, a little far away, about 1400 light years […]


Auroras, those effects of light in the upper layers of the atmosphere due to charged ions and moving by magnetism of the planet. The effect of the solar wind on […]


Despite appearances is not pulling Photoshop composition but a pretty picture with the moon and discovered comet C / 2014 Q1 (PanSTARRS) absolutely nothing (1 year). Said kite is visible […]

Today I will talk about a fictitious particles called phonons. Phonons themselves are not particles do not exist, something virtual. It is far more than a wave, the vibration of […]


This is not science fiction. This image is from a real dual stars 3 thousand light years away from here (so the image is 3000 years old from now). The […]
