Water vapour plumes on Jupiter’s moon Europa (artist’s impression)
This artist’s impression shows Jupiter and its moon Europa using actual Jupiter and Europa images in visible light. The Hubble ultraviolet images showing the faint emission from the water vapour plumes have been superimposed, respecting the size but not the brightness of the plumes.

Jupiter’s Irregular Satellites

The planet Jupiter has 67 confirmed moons. This gives it the largest retinue of moons with “reasonably secure” orbits of any planet in the Solar System. In fact, Jupiter and its moons are like a miniature solar system with the inner moons orbiting faster than the others. Eight of Jupiter’s moons are regular satellites, with prograde and nearly circular orbits that are not greatly inclined with respect to Jupiter’s equatorial plane. The remainder of Jupiter’s moons are irregular satellites, whose prograde and retrograde orbits are much farther from Jupiter and have high inclinations and eccentricities. These moons were probably captured by Jupiter from solar orbits. There are 17 recently discovered irregular satellites that have not yet been named.

Launched in 1990 aboard the Space Shuttle Discovery, it was destined to become the greatest telescope to date in history.

One of the most profound revelations occurred in 1996 when a group of scientists decided to find the…

Math is Beautiful, math is the absolute truth and that makes it beautiful. Mathematicians even go so far as calling it an art form. 

mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show - Bertrand Russel 

One of the most amazing equations, in my opinion, is the Lorentz factor, 

Virtually all of the mathematics behind Einsteins theory or special relativity can be reduced back to this one, simple equation. basically, these few lines describe exactly what happens when you travel close to the speed of light, and the fact that it is as simple and short as it is, is beautiful.

The 5 Massive New Telescopes That Will Change Astronomy Forever

The biggest building boom in the history of astronomy is upon us. In Chile and Hawaii and in space, astronomers are getting powerful telescopes that dwarf the current state-of-the-art instruments. When the mountain blasting and the mirror polishing are all done, we will have the clearest and most detailed views of outer space ever.

This boom has long been in the works for years, as billion-dollar telescopes don’t just fund and plan themselves.Now, these telescopes are starting to break ground. “If it all plays out as expected and budgeted,” writes Dennis Overbye in the New York Times, “astronomers of the 2020s will be swimming in petabytes of data streaming from space and the ground.” Let’s take a closer took at what these billion-dollar telescopes can do for astronomy in the decades to come.

Spacecraft escaping the Solar System

This shows the current positions and other interesting data of the five spacecraft which are leaving the Solar System on escape trajectories - our first emissaries to the stars. On this scale, the nearest star to the Sun would be approximately 100 meters away, and it would take Voyager 1 about 70,000 years to cover that distance.
