‘Copenhagen’ in Jerusalem revisits the Nazi-era meeting that shaped the nuclear age

Copenhagen in Jerusalem’s Khan Theatre probes truth, memory, and nuclear ethics through the enigmatic 1941 meeting of Bohr and Heisenberg.

The Niels Bohr Institute in Copenhagen was founded in 1921 as the Institute for Theoretical Physics of the University of Copenhagen by Danish theoretical physicist Niels Bohr.

US researchers decipher secrets behind Benjamin Franklin’s paper money

Not only Poor Richard’s Almanack and Pennsylvania Gazette – American founding father Benjamin Franklin also worked to prevent the counterfeiting of Colonial bills.

 Prof. Khachatur Manukyan and his team employed cutting-edge spectroscopic and imaging instruments to get a closer look than ever at the inks, paper and fibers that made Benjamin Franklin’s bills distinctive and hard to replicate.

For first time, scientists use neutrinos to create 'ghostly' map of Milky Way

The new mapping method may allow astronomers to study previously obscured parts of the galaxy and of the universe.

Israeli astrophysicists may have solved the mystery of early massive galaxies

A new theoretical model made by Israeli astrophysicists reveals an excess of massive galaxies, in contrast to previously accepted theories.

How does Jupiter appear in different colors?

Magnetic oscillations produce the different colored bands and interact with the massive storms on Jupiter's surface.

 This photo of Jupiter, taken from the Hubble Space Telescope on June 27, 2019, features the Great Red Spot, a storm the size of Earth that has been raging for hundreds of years.

Scientists discover that galactic collisions cause quasars - study

Contrary to previous beliefs that the quasars are formed at the peak of galactic collision, researchers found that they are actually formed during the initial stages of collision.

 This artist’s impression shows how ULAS J1120+0641, a very distant quasar powered by a black hole with a mass two billion times that of the Sun, may have looked.

Detailed dark matter map provides further support for Einstein's theory of general relativity

Astronomers have created the most detailed map of dark matter distribution.

 One of the Unit Telescopes of ESO's Very Large Telescope (VLT) is producing artificial stars in the skies above the Atacama Desert, above the Milky Way.

What are mysterious cosmic objects shining brighter than the sun?

They produce way more energy than the sun and appear to break a physical boundary called the Eddington limit - now scientist found a possible explanation.

 Swift X-ray observations of galaxy NGC 5408 indicate its ultraluminous X-ray source undergoes periodic changes every 115.5 days. This cycle, astronomers suspect, is linked to the orbit of a donor star around a middleweight black hole, as shown in this artist's view.
