“Shaking the Fabric of Spacetime” –Recreating Quark Matter of the Big Bang

Quarks

 

In 2017, an international group of astronomers and physicists excitedly reported the first simultaneous detection of light and gravitational waves from the same source–a merger of two neutron stars. In the world of astrophysics, Aug. 17, 2017, was a red-letter day. “This is a game-changer for astrophysics,” said UC Santa Barbara faculty member Andy Howell, who leads the supernova group at the Las Cumbres Observatory (LCO). “A hundred years after Einstein theorized gravitational waves, we’ve seen them and traced them back to their source to find an explosion with new physics of the kind we’ve only dreamed about.”

The Quasar Enigma –Massively Dense Luminous Objects at the Dawn of the Universe

 

Quasars of Early Universe

 

Black holes are usually formed in the explosive deaths of massive stars. In dense environments like globular clusters and the cores of massive galaxies, several black holes can merge together, forming an even more massive black hole. In addition, black holes at the centers of galaxies can accrete infalling gas, gaining in mass and size. If this process continues for billions of years, the black hole can become a supermassive black hole, like the one located at the center of our Milky Way Galaxy, weighing in at four million times the mass of the sun.

At Dawn of the Human Species –Milky Way’s Central Black Hole Slingshotted a Star at a Blistering 6 Million KPH

 

Supermassive Black Hole

 

“Seeing this star is really amazing as we know it must have formed in the galactic center, a place very different to our local environment. It is a visitor from a strange land,” said NASA Hubble Fellow Ting Li with the Carnegie Observatories and Princeton University, about the discovery of the ultrafast star, S5-HVS1 in 2019, traveling at a blistering 6 million km/h. The doomed star was slingshotted by the supermassive black hole at the heart of the Milky Way five million years ago at the dawn of the human species.

Superbubbles of the Cosmos –Massive Nuclear Particle Accelerators May Be Source of Cosmic Rays

Galaxy NGC 3079

 

In 2019, two mysterious globular structures were spotted in the galaxy NGC 3079, located 67 million light years from Earth. Astronomers unveiled nuclear “super bubbles” thousands of light years wide that act like particle accelerators 100 times more powerful than the Large Hadron Collider, and are around 2,000 times longer, on average, than our solar system.

“Something Unknown was Tugging at the Spacecraft” –Radio Signals Revealed Deep Mysteries of Saturn and Jupiter

Cassini Mission

 

Radio signals from two NASA probes, Cassini at Saturn (above) and Juno at Jupiter, allowed researchers to pierce the swirling clouds that hide the deep interiors of Jupiter and Saturn, where crushing pressure transforms matter into states unknown on Earth –“the two planets are more complex than we thought,” said Ravit Helled, a planetary scientist at the University of Zurich in Switzerland. “Giant planets are not simple balls of hydrogen and helium.”
