“An Incredible Mystery” –Supernova Obscured the Glow of Entire Galaxies

Brightest Flash Ever

 

“A billion years ago, something in the whirling darkness of space erupted with a fury that obscured the glow of entire galaxies,” reports Robin Andrews in Quanta after scientists at the Harvard-Smithsonian Center for Astrophysics announced the discovery on August 15th of the most massive star ever known to be destroyed by a supernova explosion, challenging existing models of how massive stars die and providing insight into the death of the first stars in the universe.

“A Cosmic Forest” –Primordial Black Holes May Unveil Nature of Dark Matter

 

Ancient Quasars

 

New research has focused on the abundance of primordial black holes that formed just fractions of a second after the Big Bang that are 50 times more massive than the sun, analyzing the interaction of the light emitted from these extremely distant quasars with the cosmic web, a network of filaments composed of gas and dark matter present throughout the universe.

“Mindboggling” –A City-Sized Object So Massive It Shouldn’t Exist

Pulsar

 

Though astronomers and physicists have studied and marveled at neutron stars for decades where just a single sugar-cube worth of neutron-star material would weigh 100 million tons here on Earth, or about the same as the entire human population, many mysteries remain about the nature of their interiors: Do crushed neutrons become “superfluid” and flow freely? Do they breakdown into a soup of subatomic quarks or other exotic particles? What is the tipping point when gravity wins out over matter and forms a black hole?

The Ultimate Mystery? –“Consciousness May Exist in the Absence of Matter” (Weekend Feature)

 

Dark Matter

 

“I have a much easier time imagining how we understand the Big Bang than I have imagining how we can understand consciousness,” says Edward Witten,  theoretical physicist at the Institute for Advanced Study in Princeton, New Jersey who has been compared to Isaac Newton and Einstein.

China Fine-Tunes Earth’s Largest Radio Telescope — “Amazing Discoveries Ahead”

Crab Nebula Pulsar

 

“Some strange signals have been found, but it’s hard to confirm their origins, because these signals do not repeat,” says Li Di, chief scientist at FAST, China’s Five-hundred-meter Aperture Spherical Radio Telescope, the world’s most sensitive listening device. “We look for not only television signals, but also atomic bomb signals. We’ll give full play to our imaginations when processing the signals,” Li states. “It’s a complete exploration, as we don’t know what an alien is like.”

“Unknown Physics” –Darkest Mystery of the Cosmos Deepens

Spiral Galaxy

 

In an interview with The Atlantic, Noble Prize winning physicist Adam Riess said: “I have absolutely no clue what dark energy is. Dark energy appears strong enough to push the entire universe – yet its source is unknown, its location is unknown and its physics are highly speculative.”

“Interstellar” –Second Object Detected from Beyond Our Solar System

Oumuamua

 

NASA’s Scout system, which is located at NASA’s Jet Propulsion Laboratory in Pasadena, California, flagged a newly discovered comet object as possibly being interstellar. if confirmed as interstellar, it would be only the second such object detected. The first, the infamous ‘Oumuamua, was discovered by researchers from the University of Hawaii -supported by the NASA Astrobiology Institute- on Oct. 19, 2017, more than a month after it passed its closest point to the Sun. They named the object after the Hawaiian word for “scout.” In the months that followed it’s detection, ‘Oumuamua’s behavior baffled astronomers leading some to view the cosmic prodigy as an alien probe.
