“We discovered the so far largest ordered magnetic fields in the universe, extending over 5-6 million light years”, says Maja Kierdorf from Max Planck Institute Bonn. Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

Portal Proposed that Links Our Visible Standard-Model Universe With the Dark, Invisible Universe

Once upon a time, the Universe was just a hot soup of particles. In those days, together with visible particles, other particles to us hidden or dark might have formed. Billions of years later scientists cataloged 17 types of visible particles, with the most recent one being the Higgs boson, creating the 'Standard Model'. However, they are still struggling to detect the hidden particles, the ones that constitute the dark sector of the Universe.

SunStroke! Landscape of Comet 67p/Churyumov-Gerasimenko Dramatically Altered As It Approached the Sun

 The Rosetta spacecraft documented unique changes spotted on comet 67p/Churyumov-Gerasimenko as it approached the sun --growing fractures, collapsing cliffs and rolling boulders on the comet's surface. A study published March 21, 2017 in the journal Science summarizes the types of surface changes observed during the two years that the European Space Agency's Rosetta spacecraft spent investigating comet 67P/Churyumov-Gerasimenko. Notable differences are seen before and after the comet's most active period -- perihelion -- when it reached its closest point to the Sun along its orbit.

The Missing Galaxies of the Cosmos

Astronomers have developed a way to detect the ultraviolet (UV) background of the Universe, which could help explain why there are so few small galaxies in the cosmos. UV radiation is invisible but shows up as visible red light when it interacts with gas. An international team of researchers has now found a way to measure it using instruments on Earth. The researchers said their method can be used to measure the evolution of the UV background through cosmic time, mapping how and when it suppresses the formation of small galaxies.

The silence of an immense desolate land in which to search for reverberations coming from the time at which everything began. The Simons Observatory will be built in the Chilean Atacama desert at an altitude of several thousand meters for the purposes of studying primordial gravitational waves which originated in the first instants of the Big Bang.

NASA: "Giant Mars Volcano and Earth's Dinosaurs Went Extinct About the Same Time"

"We estimate that the peak activity for the volcanic field at the summit of Arsia Mons probably occurred approximately 150 million years ago--the late Jurassic period on Earth--and then died out around the same time as Earth's dinosaurs," said Jacob Richardson, a postdoctoral researcher at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It's possible, though, that the last volcanic vent or two might have been active in the past 50 million years, which is very recent in geological terms.

Law Controlling Bizarre Behavior of Black Holes --"Points to a Deeper Understanding of Realty"

 

Black-holes

 

A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space—is also true for cold helium atoms that can be studied in laboratories. "It's called an entanglement area law," says Adrian Del Maestro, a physicist at the University of Vermont who co-led the research. That this law appears at both the vast scale of outer space and at the tiny scale of atoms, "is weird," Del Maestro says, "and it points to a deeper understanding of reality."

Mars, The Ringed Planet? --"Had Them in the Distant Past and May Again With the Disintegration of Its Mystery Moon, Phobos"

It's possible that Mars had rings at one point and may have them again someday. That's the theory put forth by Purdue University scientists have developed a model that suggests that debris that was pushed into space from an asteroid or other body slamming into Mars around 4.3 billion years ago and alternates between becoming a planetary ring and clumping up to form a moon.

"It's a cosmic miracle," said Volker Bromm of The University of Texas at Austin, referring to the precise set of conditions present half a billion years after the Big Bang that allowed these behemoths to emerge. "It's the only time in the history of the universe when conditions are just right" for them to form.
