A blog mainly about our world and our universe and the lenses we use to uncover their mysteries: science, reason, and imagination--with random music, thoughts, and poetry thrown in as well for good measure.

Alpha Centauri
Alpha Centauri is a triple star system located only 4.3 light years away towards the constellation Centaurus. It is the closest star system to our own, with Proxima Centauri, the dimmest of the three, as the closest star. Alpha Centauri A and B form a binary system, orbiting each other at a distance only slightly more than that between Uranus and our Sun.
Alpha Centauri A, also called Rigil Kentaurus, is the brightest star in the constellation Centaurus and is the same type of star as our Sun. Alpha Centauri B is smaller and less bright than our Sun, but is still similar. The first Earth sized exoplanet orbiting a Sun like star was discovered orbiting Alpha Centauri B, though its orbit is much too small and thus the planet is much too hot for life as we know it to exist there.

First Look: Venus Date: 22 Oct 1975
The Soviet Union’s Venera 9 lander snapped this photo of Venus during its 53-minute mission on the planet’s hellish surface. It is one of the first photos sent back from the surface of another planet.The image is of the surface of Venus at about 32 S, 291 E. The lander touched down at 5:13 UT( with the sun near zenith) on 22 October 1975 and operated for 53 minutes, allowing return of this single image.The white object at the bottom of the image is part of the lander. The distortion is caused by the Venera imaging system. Angular and partly weathered rocks, about 30 to 40 cm across, dominate the landscape, many partly buried in soil. The horizon is visible in the upper left and right corners.

    When you hear something you either don’t understand or agree with and you feel a judgmental attitude sprouting, dig it up. Don’t let it take root because it will grow weeds that kill your opportunity to learn and love the people around you, it will grow vines that suffocate any chance of compassion growing for one another, and eventually, if you let it take root and grow, it will construct a barricade that closes you into the lonely solidarity of self-righteousness.
