Astronomers have found an extraordinary trail of gas greater than 300,000 light years across originating from a nearby galaxy called NGC 4569, according to a report in Astronomy & Astrophysics.
The tail is comprised of hydrogen gas, the material new stars are born from, and is five times longer than the galaxy itself.

Did you know that a child’s brain absorbs much more radiation than that of an adult?
Dr. Martin Blank, Ph.D., from the Department of Physiology and Cellular Biophysics at Colombia University, has joined a group of scientists from around the world who are making an international appeal to the United Nations regarding the dangers associated with the use of various electromagnetic emitting devices, like cells phones and WiFi.
China has proposals for gravitational wave observatories drafted, but will the government approve them? How will they affect the country’s rank in space research?
The scientists at LIGO may be celebrating, but they’re about to have some stiff competition.
The People’s Republic of China now has three projects lined up to investigate gravitational waves as reported by the state media yesterday. These projects were decided upon just days after US scientists confirmed Einstein’s prediction.
Astrophysicists famously proved Einstein’s theory on the existence of gravitational waves last week. Here’s the less covered part of it all: It might, down the line, bring us closer to moving through time.
A now-famous team of astrophysicists shocked the world Thursday after recording the gravitational waves of two black holes slamming into each other 1.3 billion light-years away.
This detection supports Einstein’s general theory of relativity in a way that revolutionizes scientific understanding of how space and time behave in extreme environments, and astrophysics will never be the same.
You know what they say about rules…
If you thought regular black holes were about as weird and mysterious as space gets, think again, because for the first time, physicists have successfully simulated what would happen to black holes in a five-dimensional world, and the way they behave could threaten our fundamental understanding of how the Universe works.
The simulation has suggested that if our Universe is made up of five or more dimensions — something that scientists have struggled to confirm or disprove — Einstein’s general theory of relativity, the foundation of modern physics, would be wrong.
In other words, five-dimensional black holes would contain gravity so intense, the laws of physics as we know them would fall apart.
We don’t live in a world that’s pinning the survival of humanity of Matthew McConaughey’s shoulders, but if it turns out the plot of the 2014 film Interstellar is true, then we live in a world with at least five dimensions. And that would mean that a ring-shaped black hole would, as scientists recently demonstrated, “break down” Einstein’s general theory of relativity. (And to think, the man was just coming off a phenomenal week.)
In a study published in Physical Review Letters, researchers from the UK simulated a black hole in a “5-D” universe shaped like a thin ring (which were first posited by theoretical physicists in 2002). In this universe, the black hole would bulge strangely, with stringy connections that become thinner as time passes. Eventually, those strings pinch off like budding bacteria or water drops off a stream and form miniature black holes of their own.
This is wicked weird stuff, but we haven’t even touched on the most bizarre part. A black hole like this leads to what physicists call a “naked singularity,” where the equations that support general relativity — a foundational block of modern physics — stop making sense.

Electrons which act like slow-pouring honey have been observed for the first time in graphene, prompting a new approach to fundamental physics.
Electrons are known to move through metals like bullets being reflected only by imperfections, but in graphene they move like in a very viscous liquid, University of Manchester researchers have found.
The possibility of a highly viscous flow of electrons in metals was predicted several decades ago but despite numerous efforts never observed, until now as reported in the journal Science.
The 5 Dimensional Black Hole could break the theory of relativity: Simulation suggests strange rings with ‘ultragravity’ that defy physics may exist.

Researchers from the University of Cambridge and Queen Mary University of London made the discovery after simulating a black hole shaped like a very thin ring using computer models.
A trio of physicists in Europe has come up with an idea that they believe would allow a person to actually witness entanglement. Valentina Caprara Vivoli, with the University of Geneva, Pavel Sekatski, with the University of Innsbruck and Nicolas Sangouard, with the University of Basel, have together written a paper describing a scenario where a human subject would be able to witness an instance of entanglement—they have uploaded it to the arXiv server for review by others.

Two astronomers fought for credit when Neptune’s presence was confirmed in 1846: John Couch Adams from Britain, and Urbain Le Verrier from France. Both had used math and physics to predict Neptune’s position, but Le Verrier’s prediction turned out to be more accurate. See references.
