Between 2010 and 2019, our understanding of the cosmos underwent significant changes. A series of monumental findings, many of which validated Einstein’s predictions, ushered us into what some refer to as the “golden age of astronomy.”
Cosmic Echoes: A New Language
We’ve identified cosmic echoes, which may carry crucial information about the universe’s inception. Originating from the Big Bang, these echoes, albeit weakening, convey essential details about the universe’s early state. A novel research proposed that intelligent beings might even use these echoes to send information, a concept more efficient than traditional radio signals.

Wandering Black Holes
In a surprising discovery, 13 black holes were identified wandering in dwarf galaxies, not far from our Milky Way. These are relatively small black holes, some residing outside the centers of their home galaxies, hinting at past intergalactic mergers.
Galactic Cannibalism
Astronomers Raja Guhathakurta and David Reitzel shed light on the phenomenon of “galactic cannibalism.” Large galaxies, they found, grow by consuming smaller ones. This process, evident from star trails in the Andromeda galaxy, leads to the formation of larger galaxies over time.
Hyper-Fast Stars & Black Holes
The star S5-HVS1, discovered to be hurtling out of our galaxy at staggering speeds, offers proof of the gravitational prowess of black holes. Originating from a dance between a black hole and a binary star system, the star was ejected and is now on an intergalactic journey.
Dark Matter Mysteries
Fritz Zwicky, almost a century ago, first hinted at the existence of dark matter. While its existence remains to be concretely proven, its gravitational interactions have been evident in several celestial phenomena.
The Universe’s Largest Black Hole
Within the galaxy HOME 15A, researchers discovered the largest known black hole, possessing mass 40 billion times that of our sun. Its formation is attributed to the merger of several smaller galaxies.
Higgs Boson: The God Particle
In 2013, a pivotal moment in particle physics came with the Nobel prize recognition of the Higgs mechanism. This concept, which explains the mass of elementary particles, culminated in the identification of the Higgs boson particle in 2012.
As the universe continually expands, so does our quest for knowledge. With the emergence of novel research tools and passionate scientists, we can anticipate further groundbreaking discoveries that will continue to reshape our understanding of the vast cosmos.
