‘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.

Ceres –A New Look at the Relic Ocean World

Ceres Dwarf Planet

 

“Ceres –the only dwarf planet in the inner Solar System–has gained a pivotal role in assessing the origin, evolution and distribution of organic species across the inner solar system,” said Southwest Research Institute scientist Simone Marchi, about high abundance of carbon on Ceres’ near surface, which could be due to an excess of organic matter, possibly formed locally due to water-rocks chemistry.”One has to wonder about how this world may have driven organic chemistry pathways, and how these processes may have affected the make-up of larger planets like the Earth.”

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

“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.”

“Anomaly?” Odd Dwarf Galaxy Evolved Around a Massive Black Hole

 

ESO 495-21

 

A tiny dwarf galaxy, ESO 495-21, three percent the size of the Milky Way, harbors a supermassive black hole that may offer clues as to how black holes and galaxies evolved in the early Universe. The origin of the central supermassive black holes in galaxies is still a matter of debate — do the galaxies form first and then crush material at their centers into black holes, or do pre-existing black holes gather galaxies around them? Do they evolve together — or could the answer be something else entirely?
