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.

“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.”
“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.”
“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.”

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?
