First black hole ever detected is more massive than we thought

New observations of the first black hole ever detected have led astronomers to question what they know about the Universe’s most mysterious objects. Source: https://phys.org/news/2021-02-black-hole-massive-thought.html…

Quantum collaboration gives new gravity to the mysteries of the universe

Scientists have used cutting-edge research in quantum computation and quantum technology to pioneer a radical new approach to determining how our Universe works at its most fundamental level. …

Supercomputer turns back cosmic clock

Astronomers have tested a method for reconstructing the state of the early universe by applying it to 4000 simulated universes using the ATERUI II supercomputer at the National Astronomical Observatory of Japan (NAOJ). They found that together with new observations, the method can set better constraints on inflation, one of the most enigmatic events in the history of the universe. The…

Galaxies have magnetic fields, too! Images here

Until recently, magnetic fields in the outskirts of galaxies were too faint to be detected. Although it’s still not clear what causes them or how they’re maintained, astronomers have started to create images of their observations of galaxies’ magnetic fields producing beautiful aurora-like effects. See them here. Source: https://earthsky.org/space/images-of-magnetic-fields-in-galaxies…

What is the Milky Way?

When someone says “Milky Way,” do you think of the starry pathway across our sky, or of the great pinwheel-shaped galaxy in space? Both are correct! Source: https://earthsky.org/astronomy-essentials/what-is-the-milky-way-galaxy…

Large proto-cluster of galaxies discovered in the midst of clearing the cosmic fog

When the universe was about 350 million years old it was dark: there were no stars or galaxies, only neutral gas—mainly hydrogen—the residue of the Big Bang. That foggy period began to clear as atoms clumped together to form the first stars and the first quasars, causing the gas to ionize and high-energy photons to travel freely through space.

We heart the Earth and sky

This Valentine’s Day, we find so much to love in the many heart-shaped objects created by Mother Nature that can be found right here on Earth or all the way to the deepest reaches of the sky. Source: https://earthsky.org/space/heart-shaped-objects-in-nature-space-earth-valentines-day…

Happy birthday to Galileo, born February 15

One of our greatest astronomers, Galileo Galilei, was born February 15, 1564. His discoveries with the improved telescopes he made changed the way we view the universe – and got him in trouble with the church. Source: https://earthsky.org/human-world/galileos-birthday-feb-15-1564…

A brief history: What we know so far about fast radio bursts across the universe

Fast radio bursts are one of the great mysteries of the universe. Since their discovery, we have learned a great deal about these intense millisecond-duration pulses. Source: https://phys.org/news/2021-02-history-fast-radio-universe.html…
