Orbits of the Planets
A scale model of the orbits of the planets in our solar system. The inner planets’ orbits and sun are to the same scale. They would fit in the smallest orbit of the outer planets. The sun’s light takes over 4 hours to reach neptune at a mean distance of 4,504,300,000 kilometers.

Satellite Finds Evidence of Antimatter Belt Around Earth
Data from the cosmic ray satellite PAMELA has added substantial weight to the theory that the Earth is encircled by a thin band of antimatter.The satellite, named Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics, was launched in 2006 to study the nature of cosmic rays — high-energy particles from the Sun and beyond the solar system which barrel into Earth.
When those cosmic rays smash into molecules in the Earth’s upper atmosphere, a shower of smaller particles is created. Physicists have assumed that a small number of those resulting particles will be anti-protons.
Most of those will be instantly annihilated when they collide with particles of ordinary matter. But those which don’t collide should get trapped in the Earth’s torus-shaped Van Allen radiation belt, and form a layer of antimatter in the Earth’s atmosphere.

Space: You Are Here poster series by Mike Gottschalk
Space is all big and shit, yo. I know most people are already aware of this, but sometimes you just need to put things in perspective.
oh, did you plan on feeling significant today?
and once again I will say “blow me” to anyone who believes that we’re the only life in this universe.

Juno’s Jupiter mission may yield clues to Earth’s origins: Starting Aug. 5, NASA will enter the launch period for the spacecraft Juno, which will begin an unprecedented exploration of Jupiter’s secrets. “We are after the recipe for planet-making,” says a scientist.

The asteroid in the Earth’s orbit around the sun has been hiding from view, mostly overhead during daylight, study finds.

Jupiter over Ephesus - NASA photos
A brilliant Jupiter shares the sky with the Full Moon tonight. Since Jupiter is near opposition, literally opposite the Sun in planet Earth’s sky, Jupiter will rise near sunset just like the Full Moon. Of course, opposition is also the point of closest approach, with Jupiter shining at its brightest and offering the best views for skygazers.
