Ultramassive–The largest black hole ever discovered can fit 30 billion suns. We found it with gravity and bent light reports Space.com. The black hole in the galaxy cluster Abell 1201 packs a mass of 30 billion suns.
Why the earliest galaxies are sparking drama and controversy among astronomers, reports NPR. “If you were a paleontologist, you would dig deeper and deeper to find the oldest bones. In astronomy, what we do is look at our history,” says Jorge Moreno, an associate professor of astronomy at Pomona College. “We have to look back in time, but we don’t have a time machine. So what we do is we look at really faraway distances.”
We are not empty–Carl Sagan was wrong: The concept of the atomic void is one of the most repeated mistakes in popular science. Molecules are packed with stuff, reports Aeon.com.
Something Is Suppressing The Growth of The Universe, reports Science Alert. “If gravity acts like an amplifier enhancing matter perturbations to grow into large-scale structure, then dark energy acts like an attenuator damping these perturbations and slowing the growth of structure,” say University of Michigan physicists Nhat-Minh Nguyen, Dragan Huterer, and Yuewei Wen.
Aliens on TRAPPIST-1e could find us by our pollution, reports Earth & Sky. “This model has the capability to analyze UV to millimeter wave transmission, reflected light and emission data for exoplanets with a wide range of atmospheric compositions, temperatures and pressures.”
A Mysterious Hidden Force Is Generating Water on The Moon, reports Science Alert. “A new study suggests that waves of electrons, arriving indirectly from Earth and the Sun, are contributing to the formation of frozen water on the lunar surface.”
JWST smells something “fishy” on nearby exoplanet, reports SyFy. Exoplanet K2-18 b Looks Habitable and Maybe Even Occupied. “New observations with JWST suggest it may be a Hycean (a mashup of hydrogen and ocean) world with liquid water oceans and a hydrogen-rich atmosphere.”
NASA Pledging a new, transparent, scientifically rigorous look at U.F.O.s, NASA on Thursday said it had appointed a director of research on the topic — and then kept the name of the director a secret for about seven hours, reports The New York Times.
Powerful observatories reveal 5 breathtaking corners of the universe hidden to human eyes (images), reports Space.com.”There’d be countless more scattered across the universe, hidden not just by distance but also because your eyes aren’t built to perceive the signals they emit — unseeable signals like infrared light, radio waves and X-ray emissions. In fact, humans can only see a tiny fraction of the electromagnetic spectrum. It’s a sliver known as the “visible light region.”
