Today's "Planet Earth Report" --WW 11 High-Tech Nazi Submarine Found --"On a Mysterious Mission to South America"

Type-xxi_4

Two days before the Allied forces declared victory over Nazi Germany at the end of World War II, a high-tech German submarine set out from Denmark on a mysterious mission. The sub was a brand-new Type XXI U-boat, hailed as the most advanced Nazi submarine of its time. It was deadly quiet, superfast and allegedly capable of traveling from Europe to South America without having to surface.

Cluster of Stars Harbors a Massive Mystery Source of Cosmic Rays

"This particular source of gamma rays was found towards an unusual cluster of stars which harbors one of the Milky Way's most massive and energetic young stars, a luminous blue variable star called LBV1806-20," says Associate Professor Gavin Rowell, from the University of Adelaide's High Energy Astrophysics Group and leader of Australia's participation in HESS -the High Energy Stereoscopic System (HESS) gamma ray telescopes in Namibia. "The cluster of stars also harbors a rare, extremely magnetic, neutron star known as a magnetar, but we think the gamma ray emission could be linked to the luminous blue variable star.

From the Farside --"Prehistoric Humans May Have Performed Brain Surgery"

  98120

 

Oh, my! Humans have been performing brain surgery—or at least drilling holes in one others’ skulls—for thousands of years, reports today's Science. But how did they get their practice? A new study analyzing an exquisitely bored hole in the skull of a 5000-year-old cow suggests they may have honed their skills on animals.

Z-Machine --World’s Most Powerful X-ray Source "Will Create a White-Dwarf Star on Earth" (WATCH Today's 'Galaxy' Stream)

“The really amazing thing about this research is that it changes the way astronomy has been conducted in the past,” said Don Winget, the director of CAPP and a professor in the Department of Astronomy. “There were a lot of things we thought we understood, or knew we didn’t understand in astrophysics. By re-creating those conditions and making real measurements in the laboratory, we’re changing how we think of not only astronomy as a field, but how we think of specific astronomical objects.”

Today's "Planet Earth Report" --“A Highly Altered, Degraded System” -Since 2016, Half of All Coral in the Great Barrier Reef Has Died

"Once upon a time, there was a city so dazzling and kaleidoscopic, so braided and water-rimmed, that it was often compared to a single living body. It clustered around a glimmering emerald spine, which astronauts could glimpse from orbit. It hid warm nooks and crannies, each a nursery for new life. It opened into radiant, iris-colored avenues, which tourists crossed oceans to see. The city was, the experts declared, the planet’s largest living structure."

"The Star Killer" --Rare 'Butterfly' Galaxy with Two Supermassive Black Holes

While most galaxies in the universe hold only one supermassive black hole at their center, NGC 6240 contains two--and they're circling each other in the last steps before crashing together. New research reveals how gases ejected by those spiraling black holes, in combination with gases ejected by stars in the galaxy, may have begun to power down NGC 6240's production of new stars.  The team also shows how these "winds" have helped to create the galaxy's most tell-tale feature: a massive cloud of gas in the shape of a butterfly.

"We'll Find Planets of a Kind Never Seen Before" --SpaceX Will Launch NASA's TESS Satellite Today @6:51 PM EST (WATCH All-Day Live)

“One of the biggest questions in exoplanet exploration is: If an astronomer finds a planet in a star’s habitable zone, will it be interesting from a biologist's point of view?” said George Ricker, TESS principal investigator at the Massachusetts Institute of Technology (MIT) Kavli Institute for Astrophysics and Space Research in Cambridge, which is leading the mission rescheduled for launch today. “We expect TESS will discover a number of planets whose atmospheric compositions, which hold potential clues to the presence of life, could be precisely measured by future observers.”

Remnants Found of a Lost Planet That Once Roamed Our Solar System

"What we're claiming here," said Philippe Gillet, a planetary scientist at the Federal Institute of Technology in Lausanne, "is that we have in our hands a remnant of this first generation of planets that are missing today because they were destroyed or incorporated in a bigger planet." What Gillet was referring to are Fragments of a meteorite that fell to Earth about a decade ago provide compelling evidence of a lost planet that once roamed our solar system.

"We Truly Don't Know What It Is" --Mystery Milky-Way Spectrum of Light Observed

 

Dark

 

"We use special telescopes to catch X-ray light in the sky, and while looking at these X-rays, the telescopes noticed an unexpected feature and captured a spectrum of light, which is not produced by any known atomic emission," said University of Miami astrophysicist Nico Cappelluti. "This emission line is now called the 3.5 kiloelectron volt (keV). One interpretation of this emission line is that it's produced by the decay of dark matter."

Today's Top Science Headline --Hunt for Wonder Drugs at the North Pole In a Race Against Deadly Antibiotic Resistance

"Sixty percent of the drugs we take today were developed from natural products, and most of those products have terrestrial sources. Currently, only seven FDA-approved pharmaceuticals in clinical use have marine sources, compared to hundreds of land-based drugs. And while scientists have isolated more than 30,000 unique organic compounds from marine organisms, they believe there are hundreds of thousands more to be found."
