“This is a great discovery!” said ESO team member Themiya Nanayakkara in fall of 2018 about the discovery that almost all of the sky is invisibly glowing with Lyman-alpha emission from the early Universe. “Next time you look at the moonless night sky and see the stars, imagine the unseen glow of hydrogen: the first building block of the universe, illuminating the whole night sky.”
Astronomers studying the motions of galaxies and the character of the cosmic microwave background radiation came to realize in the last century that most of the matter in the universe was not visible. About 84 percent of the matter in the cosmos is dark matter, much of it located in halos around galaxies. It was dubbed dark matter because it does not emit light, but it is also mysterious: it is not composed of atoms or their usual constituents like electrons and protons.

Albert Einstein described black holes as strange objects “where God divided by zero.” An international team of astrophysicists has now confirmed that black holes are a distinct “species” from neutron stars, which are comparable to black holes in mass and size but confined within a hard surface. A black hole is an exotic cosmic object without a hard surface predicted by Einstein’s theory of General Relativity and is confined within an invisible boundary, called an event horizon, from within which nothing, not even light, can escape.
“The fate of black holes in a quantum theory of gravity is, in my view, the most important problem in theoretical physics,” said Jorge Pullin, the Horace Hearne professor of theoretical physics at LSU.
“NASA’s ENIGMA (Evolution of Nanomachines In Geospheres and Microbial Ancestors) research team,” evolutionary biologist Paul Falkowski told The Daily Galaxy, “is focused on answering a single, compelling question in astrobiology: How did proteins evolve to become the predominant catalysts of life on Earth?

Astronomers may soon have the answer to what is perhaps the greatest mystery of modern science –is dark energy a uniform force across space and time, or has its strength evolved over eons?
