Most dying stars go out with a bang — a supernova, more specifically. But scientists recently observed a star that went out with a whisper, skipping the supernova phase and going straight into a black hole. The discovery not only teaches us more about stars, but it could also uncover the mysteries behind some of the universe's most massive black holes.

THE PICTURE OF AN ATOM " WHITE DOT "
IF YOU LOOK CLOSELY, YOU CAN SEE A STRONTIUM ION IN THE CENTRE OF THIS ION TRAP ,BETWEEN THE TIPS OF THE TWO "NEEDLE " ELECTRODES . THE TIPS OF THE NEEDLES ARE SEPARATED BY 2.3MM - ROUGHLY THE WIDTH OF A SPAGHETTI NOODLES
"The idea of being able to see a single atom with the naked eye had struck me as a wonderfully direct and visceral bridge between the miniscule quantum world and our macroscopic reality," he said in a press release. "A back-of-What When ions like this are illuminated by the right color of blue-violet laser, they absorb the light particles and emit them right back. Nadlinger realized that if he set up his camera with a long enough exposure, he might be able to capture this fleeting moment of light emission in a digital image. He placed his tripod so the lens peered through the window of the ultra-high vacuum chamber that houses the ion trap, which in turn suspends the atom, and took his shot.
the-envelope calculation showed the numbers to be on my side, and when I set off to the lab with camera and tripods one quiet Sunday afternoon, I was rewarded with this particular picture of a small, pale blue dot."
you're seeing is a single positively charged strontium atom (also known as a strontium ion) suspended in electric fields radiating from the metal electrodes around it. To get a sense of just how small this image is, the distance between the two needle-like tips you see is about 2 millimeters — roughly the width of a spaghetti noodle.
