How close could you get to the sun before burning up? Alessandra Calderin of Popular Science asked NASA engineer Ralph McNutt: The sun is about 93 million miles away from Earth, and if we think of that distance as a football field, a person starting at one end zone could get about 95 yards before burning up.
I now have the perfect excuse for being perpetually late. See, it’s not my fault: some scientists now think that time is actually slowing down! Professor Senovilla, and colleagues have proposed a mind-bending alternative. They propose that there is no such thing as dark energy at all, and we’re looking at things backwards. Senovilla proposes that we have been fooled into thinking the expansion of the universe is accelerating, when in reality, time itself is slowing down.
Oddee has screenshots of ten funny Amazon.com reviews, such as this customer’s complaint about faulty packaging for a shipment of uranium ore. What a ripoff! I hope he got his money back.
Among the views of Earth afforded astronauts aboard the International Space Station (ISS), surely one of the most spectacular is of the aurora. These ever-shifting displays of colored ribbons, curtains, rays, and spots are most visible near the North (aurora borealis) and South (aurora australis) Poles as charged particles (ions) streaming from the Sun (the solar wind) interact with Earth’s magnetic field.
The Earth and Moon were created as the result of a giant collision between two planets the size of Mars and Venus. Until now it was thought to have happened when the solar system was 30 million years old or approximately 4.5 billion years ago. But new research shows that the Earth and Moon may have formed much later – perhaps up to 150 million years after the formation of the solar system.
If dark matter exists it may take the form of mirror planets, mirror stars and mirror galaxies. Now one physicist says the most recent evidence seems to confirm this idea

A small 12 x 16 oil portrait long thought to be a copy in the style of the Renaissance master Rafael was recently discovered in a palazzo storeroom in Sassuolo, northern Italy. Art expert Mario Scalini found it as he sorted through more than 25,000 works stashed in the palazzo’s vaults.
Dark matter is distributed throughout the universe in giant, football-shaped clumps, according to new, indirect images of the mysterious substance that holds galaxies and galaxy clusters together. The work provides more evidence that dark matter, even on the largest scale, strongly affects the visible cosmos with its gravity and remains virtually unaffected in return.
There's the common notion that black holes suck in everything in the nearby vicinity by exerting a strong gravitational influence on the matter, energy, and space surrounding them. But astronomers have found that the dark matter around black holes might be a different story. Somehow dark matter resists 'assimilation' into a black hole.
