Science just brought us one step closer to solving a billion-year-old mystery

The discovery of 80 new supernovae deepens our understanding of the universe's early history and the nature of cosmic evolution.

The Oldest Black Hole Ever Discovered Is Surprisingly Big

The oldest supermassive black hole ever seen is consuming its host galaxy, which may spell doom for both the black hole and its prey.
Studying this ancient black hole could provide insights into the formation and growth of the first supermassive black holes in the universe.

Einstein's "Greatest Mistake" Could Actually Help Explain Why the Universe Is Expanding So Quickly

Only 5% of the universe is made up of "normal" matter that we can see
Dark energy, which makes up 70% of the universe, is believed to be causing the universe to expand at an increasing rate

Newly found galaxy 'Nube' should not exist, scientists say

Astronomers discovered a mysterious dwarf galaxy that challenges our current understanding of the universe.
The galaxy, named Nube, is unique due to its high levels of dark matter and low mass at its center, making it nearly invisible.

Newly discovered cosmic megastructure challenges theories of the universe

Astronomers have discovered a ring-shaped cosmic megastructure, known as the Big Ring, which challenges existing theories of the universe.
The Big Ring has a diameter of about 1.3 billion light years and is too faint to see directly, but its diameter on the night sky would be equivalent to 15 full moons.

Hubble Detects Uber-Strong Radio Transmission From Ancient "Blob"

The Hubble Space Telescope has observed the possible birthplace of the most distant fast radio burst ever observed.

The Universe in a lab: Testing alternate cosmology using a cloud of atoms

Researchers in Germany have created a tabletop quantum field simulation to explore the possible features of the early Universe.
The simulation shows that it is possible to simulate a Universe with different curvatures, indicating that the curvature of the Universe might have been different at the beginning of its existence.
The study published in Nature involved studying three possible scenarios for the Universe's early expansion: constant, accelerated, and decelerated.
