“Emergence of Human Ancestors” -A 300,000 Year-Long Beam of Energy Burst from Milky Way’s Black Hole

Milky Way Galaxy

 

 

“We always thought of our Galaxy as an inactive galaxy, with a not so bright center,” said Magda Guglielmo from the University of Sydney about 2019 Hubble Space Telescope data showing that a titanic, expanding beam of energy sprang from close to the SgrA*, the supermassive black hole in the center of the Milky Way, 3.5 million years ago, shooting a cone-shaped burst of radiation through both poles of the Galaxy and beyond into deep space.

Milky-Way Worlds May Harbor Lifeforms With Alien DNA

Alien World

 

During a keynote speech at a NASA conference a decade ago on the search for extraterrestrial life an attendee shouted out: “We have no idea what’s out there!” One of NASA’s goals is to search for life on other planets like Mars, where there was once flowing water and a thick atmosphere, or moons of the outer solar system like Europa and Enceladus, where vast water oceans churn under thick layers of ice. But what if life on those worlds doesn’t use our DNA? How could we recognize it? A 2019 DNA breakthrough may be the key to answering these questions and many more.

‘The Yeti’ -A Monster Galaxy Accidentally Discovered at Dawn of the Universe

Yeti Galaxy

 

In 2019, astronomers accidentally discovered the faint, shimmering blob of a monster galaxy cloaked in dust and a lot of mystery in the early universe. Like a cosmic Yeti, the scientific community generally regarded these galaxies as folklore, given the lack of evidence of their existence, but astronomers in the United States and Australia managed to snap a picture of the beast for the first time. The discovery provides new insights into the some of the biggest galaxies in the universe.

Dark Hearts of the Cosmos –Dazzling New Mergers of Black Holes and Neutron Stars

 

Black Holes in Globular Clusters

 

“Mergers of black holes with neutron stars are exceptionally rare in the Universe.  “An actual merger of a neutron star with a black hole happens, perhaps, once every million years in a galaxy.  To see one in the Milky Way, we would have to watch for a very long time,” Harald Pfeiffer, group leader in the Astrophysical and Cosmological Relativity department at Max Planck Institute for Gravitational Physics (AEI) in Potsdam, Germany, told The Daily Galaxy about recent neutron star-black hole merger of GW200105, detected by LIGO and Virgo in the past five years that have opened a completely new new way of observing the Universe.

The Andromeda Signal –“From No Known Particle or Atom”

 

Andromeda Galaxy 1910

 

“There’s something we just don’t understand about the internal structure of how the universe works,” said Enectali Figueroa-Feliciano, an associate professor of physics at Northwestern and the MIT Kavli Institute for Astrophysics and Space Research, reacting to what astronomers think may be the first real signal from the “dark universe.”

Is Dark Matter and Dark Energy a Fluid?

Dark Energy

 

“We now think that both dark matter and dark energy can be unified into a fluid which possesses a type of ‘negative gravity’, repelling all other material around them,” said Jamie Farnes from the Oxford University e-Research Center in 2018 about the what is perhaps the great unsolved mystery of  the Universe. “The outcome seems rather beautiful: dark energy and dark matter can be unified into a single substance, with both effects being simply explainable as positive mass matter surfing on a sea of negative masses.”
