This invisible, mysterious substance is by far the most dominant aspect of any galaxy. Finding a galaxy without any dark matter is completely unexpected; it challenges standard ideas of how galaxies work. There is no theory that predicts this type of galaxy — how it was formed is completely unknown.

Today's "Planet Earth Report" --Trade Wars and the 'Law of Unintended Consequences'

The Smoot-Hawley Tariff imposed by the U.S. in 1930 slapped 20 percent tariffs on 20,000 kinds of imported products mostly from Europe. It set off a wave of trade protectionism. Global trade fell by about two-thirds in four years during the epic event we call the Great Depression.

"Alien Life Payload?" NASA’s Kepler Spacecraft Downloads Exoplanet Science Data

Earlier this week, NASA’s Kepler team received an indication that the spacecraft fuel tank is running very low. NASA has placed the spacecraft, which has discovered 70 percent of the 3,750 exoplanets known to date, in a hibernation-like state in preparation to download the science data collected in its latest observation campaign. Once the data has been downloaded, the expectation is to start observations for the next campaign with any remaining fuel.

The University of Maine’s Climate Reanalyzer reported cities across the Northern Hemisphere experencing exceptionally high heat this week, with records breaking in North America, Europe, the Middle East, and Western Asia. Besides the long-term effects such temperatures may have on climate change, many of these weather milestones caused immediate hazards.

NASA: "Ancient Global Ocean of Jupiter's Europa Spews Surface Fossils Millions of Years Old"

In new NASA research, scientists describe Europa's global ocean as a “fossil” ocean because the bits of ocean trapped in Europa’s ice shell spend many hundreds of thousands, if not millions, of years before being carried to the surface. In other words, by the time the ocean material reaches Europa’s surface where it can be analyzed by a passing spacecraft, it no longer serves as a sample of Europa’s ocean as it is in the present. Instead, the spacecraft would actually be studying Europa’s ocean as it was a million or more years ago.

Jupiter's Moons Create a Wild Magic Show of Color and Shadows On Its Polar Auroras

New images from NASA's Juno spacecraft show an unusual "footprint" of Jupiter's moons on their parent planet's aurorae. The data reveal that, rather than casting one "shadow" in Jupiter's aurorae, the moon Io - Jupiter's fifth - casts several, in a double wing-shaped pattern, while Jupiter's largest moon, Ganymede, casts a double shadow.

Strange Triple-Star System Unique in the Cosmos --"A Laboratory for Einstein's Theories"

"This is a unique star system," said Ryan Lynch of the Green Bank Observatory in West Virginia, and coauthor on the paper. "We don't know of any others quite like it. That makes it a one-of-a-kind laboratory for putting Einstein's theories to the test." This system contains a neutron star (image above) in a 1.6-day orbit with a white dwarf star, and the pair in a 327-day orbit with another white dwarf further away.

From the Farside --"British Intelligence Services Feared China or Russia May Acquire UFO Technology"

“Even though they have been partly censored they can’t conceal the fact the UK military were interested in capturing UFO technology - or what they coyly refer to as ‘novel weapon technology’,” UFO expert  and acted as curator for The National Archives UFO project from 2008–13. Dr David Clarke told The Sun. “And the files reveal they were desperate to capture this technology - wherever it came from - before the Russians or the Chinese got hold of it first.”

Hunt Begins for the Dark Photon --5th Force of Nature: "The Portal Between the Visible and Hidden Universe"

Physicists in Italy are about to start up a new experiment designed to hunt for hypothetical particles such as the “dark photon” and carriers of a possible fifth force of nature. "Dark Photons would provide a 'portal between the visible and hidden sectors' and might also help solve other problems, such as the muon’s anomalous magnetic moment," says Mauro Raggi of the University of Rome “La Sapienza”.
