At a distance of 10 billion light-years, DES15E2mlf - a Type I superluminous supernova (SLSN-I) spotted by the Dark Energy Survey collaboration - is the most distant superluminous supernova confirmed to date. It also has one of the most massive host galaxies discovered for a SLSN-I.
Superluminous supernovae are 10 to 100 times brighter than a typical supernova resulting from the collapse of a massive star. But scientists still don't know exactly what kinds of stars give rise to their luminosity or what physical processes are involved.

DES15E2mlf is unusual even among the small number of superluminous supernovae astronomers have detected so far.

The explosion occurred about 3.5 billion years after the Big Bang at a period known as 'cosmic high noon,' when the rate of star formation in the Universe reached its peak.

It was more than three times as bright as the 100 billion stars of our Milky Way Galaxy combined.

Previous observations of superluminous supernovae found they typically reside in low-mass or dwarf galaxies, which tend to be less enriched in metals than more massive galaxies.

The international MAKS 2017 Air Show has concluded in Zhukovsky, just outside Moscow. RT highlights the most stunning moments of the six-day event which included breathtaking flight performances and racing duels between planes and cars.

The airshow show turned out to be a landmark business event, surpassing the previous MAKS 2015 spectacle with regard to business activity and deals signed.

Some 800 airspace companies took part in the event, signing contracts and memorandums worth a staggering 394 billion rubles (roughly $6.6 billion). Potential business deals exceeded 600 billion rubles (over $10 billion), according to an official statement issued following the event's conclusion.

On Sunday July 23rd, a spectacular CME emerged from the farside of the sun. Coronagraphs onboard the orbiting Solar and Heliospheric Observatory (SOHO) tracked the fast-moving cloud as it billowed into space:

NASA's STEREO-A spacecraft, which has a partial view of the sun's farside, identified the source of the blast as active sunspot AR2665, familiar to readers of Spaceweather.com who watched the behemoth cross the Earthside of the sun earlier this month. STEREO-A observed an intense flash of extreme UV radiation from the sunspot's magnetic canopy:

Strange signals emanating from a dwarf star are not evidence of extraterrestrial life. That's according to astronomers who detected the unidentified radio signals, setting off public speculation that aliens were trying to making contact with Earth.

Scientists from the Arecibo Observatory in Puerto Rico revealed last week that they were baffled by signals detected on May 12 emanating from the star Ross 128.


The wide-band radio signal was considered unusual because not only did it repeat with time, it also slid down the radio dial, going from a higher note to a lower one.

While the team were quick to point out that it was highly unlikely the signals were from aliens, that didn't stop curious conjecture around their discovery.

Over the past few years, a number of publications have emerged from scientists and researchers all over the world regarding the human magnetic field. Not only have they been studying the human magnetic field, they've also been studying the magnetic field of the planet, and how all these fields, including our own, can impact ourselves and the people around us. It's similar to quantum entanglement, in that both show that everybody and every living thing is "connected" in ways we have yet to fully understand.

Leading the charge are the brilliant scientists over at the HearthMath Institute. An internationally recognized nonprofit research and education organization, it dedicates itself to helping people reduce stress, self-regulate emotions, and build energy and resilience for healthy, happy lives.

A large portion of their research has investigated heart and brain interaction. Researchers have examined how the heart and brain communicate with each other and how that affects our consciousness and the way in which we perceive our world. For example, when a person is feeling really positive emotions like gratitude, love, or appreciation, the heart beats out a certain message. Because the heart beats out the largest electromagnetic field produced in the body, it can yield significant data for researchers. You can read more about that here.

Now, the Institute has published new research which suggests that daily autonomic nervous system activity not only responds to changes in solar and geomagnetic activity, but also synchronizes with the time-varying magnetic fields associated with geomatic field-line resonances and Schumann resonances.

In 1952, German physicist and professor W.O. Schumann of the Technical University of Munich began attempting to answer whether or not the Earth itself has a frequency - a pulse. His assumption about the existence of this frequency came from his understanding that when a sphere exists inside of another sphere, an electrical tension is created. Since the negatively charged Earth exists inside the positively charged ionosphere, there must be tension between the two, giving the Earth a specific frequency. Following his assumptions, through a series of calculations he was able to land upon a frequency he believed was the pulse of the Earth. This frequency was 10hz.

Detailed maps of the bottom of the Indian Ocean reveal deep canyons and landslides but no wreckage of Malaysia Airlines flight MH370, which went missing in 2014.

A vanished airliner rather than scientific curiosity prompted a recent extensive campaign to map a large swath of the seafloor, one of the last unexplored frontiers of our planet. Now these data have been publicly released for the first time and may offer a lasting boon to science.

On 8 March 2014, Malaysia Airlines flight MH370 took off from Kuala Lumpur en route to Beijing, lost contact with air traffic control, and disappeared. The Boeing 777, with 239 people on board, is presumed to have veered wildly off course, eventually crashing into a remote part of the southern Indian Ocean.

The Sun, now halfway through its life, might be slowing its magnetic activity, researchers say, which could lead to permanent changes in the sunspots and auroras we see.

The Sun has changed its figure, researchers say, and might keep it that way.

The structure of the Sun's surface, where sunspots live, appears to have changed markedly 23 years ago. That's when solar magnetic activity might have started slowing down, Rachel Howe (University of Birmingham, UK, and Aarhaus University, Denmark) and collaborators speculate in paper to appear in the Monthly Notices of the Royal Astronomical Society (full text here). Such a structural change might help explain the Sun's mysteriously weak cycles in recent years.

The interior of the Sun pulsates as rhythmically as a human heart. But while the heart pulses at one fairly steady frequency, the Sun reverberates at thousands of different frequencies.

Pressure changes inside the Sun create these reverberations, just like pressure changes in the air create sound. The sound waves inside the Sun are outside the range of human hearing - they're too low frequency - but if we sped them up, we could hear them just like any other sound.

The British non-profit GMWatch recently revealed the agribusiness takeover of Conabia, the National Advisory Committee on Agricultural Biotechnology of Argentina. Conabia is the GMO assessment body of Argentina. According to GMWatch, 26 of 34 its members were either agribusiness company employees or had major conflicts of interest*.

Packing a regulatory agency with conflicted individuals is one way to ensure speedy GMO approvals and Conabia has certainly delivered that. A much more subtle, but ultimately more powerful, way is to bake approval into the structure of the GMO assessment process itself. It is easier than you might think.

The Russians demonstrate that you don't need to spend a gazillion dollars to make an amazing fighter jet

This is a story of two jets-and two air shows.

The Paris Air Show was supposed to put to rest the unpatriotic criticisms of Lockheed's "5th generation" 100-gazillion-dollar baby: The majestic F-35.

It didn't.

The jet performed mediocre at best. At worst, people were basically calling it a sack of 5th generation garbage:

Around the same time that the dinosaurs became extinct on Earth, a volcano on Mars went dormant, NASA researchers have learned.

Arsia Mons is the southernmost volcano in a group of three massive Martian volcanoes known collectively as Tharsis Montes. Until now, the volcano's history has remained a mystery. But thanks to a new computer model, scientists were finally able to figure out when Arsia Mons stopped spewing out lava.

According to the model, volcanic activity at Arsia Mons came to a halt about 50 million years ago. Around that same time, Earth experienced the Cretaceous-Paleogene extinction event, which wiped out three-quarters of its animal and plant species, including the dinosaurs.

Jacob Richardson, a postdoctoral researcher at NASA's Goddard Space Flight Center in Maryland and co-author of the new study, presented the findings today (March 20) at the 48th annual Lunar and Planetary Science Conference, The Woodlands, Texas.
