Violent outbursts of seething gas from young red dwarf stars may make conditions uninhabitable on the planets that orbit them. Scientists found that flares from the youngest red dwarfs they surveyed are much more energetic than when the stars are older. They also detected one of the most intense stellar flares ever observed in ultraviolet light — more energetic than the most powerful flare from our Sun ever recorded.

The tanks, which will surround a central detector for a nearly mile-deep experiment under construction in South Dakota called LUX-ZEPLIN, will be filled with liquid that produces tiny flashes of light in some particle interactions.
Scientists, including researchers from the Department of Energy’s SLAC National Accelerator Laboratory, have compiled the most detailed catalog of such blobs using eight years of data collected with the Large Area Telescope (LAT) on NASA’s Fermi Gamma-Ray Space Telescope. The blobs, including 19 gamma-ray sources that weren’t known to be extended before, provide crucial information on how stars are born, how they die, and how galaxies spew out matter trillions of miles into space.
Leon Lederman, a co-winner of the 1988 Nobel Prize in physics for the discovery of the muon neutrino, spent his life as a leader in a range of roles promoting science. He died on October 3, 2018, at the age of 96. Lederman conducted his Nobel Prize-winning research at the U.S. Department of Energy’s Brookhaven National Laboratory in the early 1960s.

Using ALMA, an international team of astronomers found evidence that a white dwarf and a brown dwarf collided in a short-lived blaze of glory that was witnessed on Earth in 1670 as Nova sub Capite Cygni (a New Star below the Head of the Swan), which is now known as CK Vulpeculae.
The astrophysicists Mattia Galiazzo and Rudolf Dvorak from the University of Vienna, in collaboration with Elizabeth A. Silber (Brown University, USA) investigated the long-term path development of Centaurs (solar system minor bodies which originally have orbits between Jupiter and Neptune). These researchers have estimated the number of close encounters and impacts with the terrestrial planets after the so-called Late Heavy Bombardment (about 3.8 billion years ago) as well as the possible sizes of craters that can occur after a collision with the Earth (and the other terrestrial planets). The publication was recently published in Monthly Notices of the Royal Astronomical Society.
Magnetic reconnection causes space storms that can damage satellites and disrupt the grid. While it’s a common process in the universe, plasma physics researchers don’t fully understand why it occurs so abruptly and quickly. New research is supporting a theory that may hold the key.
The first-ever detection of highly energetic radiation from a microquasar has astrophysicists scrambling for new theories to explain the extreme particle acceleration. A microquasar is a black hole that gobbles up debris from a nearby companion star and blasts out powerful jets of material.
McMaster researchers have pioneered one-of-a-kind technology that could – for the first time – provide experimental evidence of how life was formed on the early Earth and show whether life could have emerged elsewhere in the universe.
Using the Hubble and Kepler space telescopes two astronomers have found the first compelling evidence for a moon outside our Solar System. The data indicate an exomoon the size of Neptune, in a stellar system 8,000 light-years from Earth.
A strange star system in our own Milky Way is producing some of the most powerful gamma rays ever seen. Messengers from this microquasar may offer a glimpse into bizarre objects at the centers of distant galaxies.
a team of researchers has used an X-ray laser to measure, for the first time, how a plasma created by a laser blast expands in the hundreds of femtoseconds (quadrillionths of a second) after it’s created. Their technique could eventually reveal tiny instabilities in the plasma that swirl like cream in a cup of coffee.

Scientists and engineers at Los Alamos National Laboratory are using a unique centrifuge facility to evaluate a flight-ready telemetry system for evaluating a nuclear weapons test missile launch.
Black holes are mysterious, but new research into black holes may shed light on the origins of life in the universe. David Garofalo, Kennesaw State University assistant professor of physics, co-authored a paper published in the Monthly Notices of the Royal Astronomical Society. The findings: the breaking up or ripping of magnetic fields near black holes may explain the way jets of energy come from black holes or contribute to that understanding.
Iowa State physicists contributed to the international collaboration that found a way to sift and sort data from the Large Hadron Collider to observe the Higgs boson decaying into a pair of bottom quarks. The observation gives physicists a better understanding of the Higgs and could lead to new physics discoveries.

Scientists improve our understanding of the relationship between fundamental forces by re-creating the earliest moments of the universe.
It sounds like the stuff of George Lucas' universe, but it may be real. There may be life on the moons of rogue planets — solitary planets that have been ejected from their host star and which drift through the galaxy. A few observations and some prevailing theories about planet formation and life inspired UNLV astrophysicists to consider this possibility. The results of their study will appear in the Monthly Notices of the Royal Astronomical Society.
The largest liquid-argon neutrino detector in the world has just recorded its first particle tracks, signaling the start of a new chapter in the story of the international Deep Underground Neutrino Experiment (DUNE).

Astronomers using ALMA, with the aid of a gravitational lens, have detected the most-distant galactic “wind” of molecules ever observed, seen when the universe was only one billion years old. By tracing the outflow of hydroxyl (OH) molecules – which herald the presence of star-forming gas in galaxies – the researchers show how some galaxies in the early universe quenched an ongoing wildfire of starbirth.
The mystery behind lunar swirls, one of the solar system’s most beautiful optical anomalies, may finally be solved thanks to a joint Rutgers University and University of California Berkeley study. The solution hints at the dynamism of the moon’s ancient past as a place with volcanic activity and an internally generated magnetic field. It also challenges our picture of the moon’s existing geology.
In a paper published today in Nature Communications, a worldwide team of researchers has used tree ring dating to confirm that two significant "cosmic events" occurred in 774 and 993 CE. Cross-cultural eyewitness accounts of red or "blood" aurora correspond with these years.
