This composite image shows a superbubble in the Large Magellanic Cloud (LMC), a small satellite galaxy of the Milky Way, located about 160,000 light years from Earth. Many new stars, some of them very massive, are forming in the star cluster NGC 1929, which is embedded in the nebula N44. The massive stars produce intense radiation, expel matter at high speeds, and race through their evolution to explode as supernovas. The winds and supernova shock waves carve out huge cavities called superbubbles in the surrounding gas. (via CHANDRA)

“Mandel was shocked to discover an alternate version of the world’s origins. He had been raised to believe that the world was less than 6,000 years old; he recalls his father telling him, on a rare family visit to the Museum of Natural History, that a dinosaur skeleton was “just rocks.””

“First, cast doubt on the science. Second, question the personal motives and integrity of the scientists. Third, magnify genuine disagreements among scientists, and cite nonexperts with minority opinions as authorities. Fourth, exaggerate the potential harm caused by the issue at hand. Fifth, frame issues as a threat to personal freedom. And sixth, claim that acceptance would repudiate a key philosophy, religious belief, or practice of a group.”

“Go out early tomorrow evening and you will see Venus and Jupiter to the west, and Saturn to the south. Use a telescope if you can. Seeing such marvels for yourself is much more immediate and personal than looking at images on the television. The natural world is fascinating, and is even more so if you are prepared to observe, to experiment, to think, and to try and understand.”

“[…] significant progress in the solutions of technical problems is frequently made not by a direct approach, but by first setting a goal of high challenge which offers a strong motivation for innovative work, which fires the imagination and spurs men to expend their best efforts, and which acts as a catalyst by including chains of other reactions.”
Why Explore Space?
In 1970, Sister Mary Jucunda wrote to NASA scientist Dr. Stuhlinger about his research into a piloted mission to Mars asking him how he could suggest to spend money on such a project when there are children starving on Earth. Stuhlinger wrote back to her a thoughtful reply that’s worth reading, especially today.
