“Fingerprints of the Big Bang” –NASA’s SPHEREx Mission Will Probe First Seconds of the Universe

SPHEREx Mission

 

Our understanding of the first seconds of our Universe’s existence is little more than an informed guess, based on inference and extrapolation. “Yet these first moments are the key to many of our most urgent and enduring cosmic mysteries,” says cosmologist Dan Hooper at the University of Chicago told The Daily Galaxy. “Understanding this era,” he adds, “is essential to understanding our universe.

“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.

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.”
