“Warping Spacetime to Explore Uncharted Realms” –NASA Seeks Out Hidden Planets at Milky Way’s Center

Milky Way Center

 

Named after Nancy Roman, known as the “Mother of Hubble,” NASA’s Nancy Grace Roman Telescope will explore uncharted regions of the galaxy for exoplanets, focusing on star-systems toward the crowded, chaotic center of our Milky Way galaxy. Studying the population properties of exoplanets will help us understand what planetary systems throughout the galaxy are like and how planets form and evolve.

“Worlds in Collision” – ‘Reawakening’ Milky Way’s Supermassive Black Hole

 blobs of gas roughly the mass of Jupiter at Milky Way's Black Hole

 

“Beautiful as it is, our Universe is constantly evolving, often through violent events like the Milky Way’s forthcoming collision with the Large Magellanic Cloud,” said Carlos Frenk, Director of the Institute for Computational Cosmology at the University of Durham. “Barring any disasters, like a major disturbance to the Solar System, our descendants, if any, are in for a treat: a spectacular display of cosmic fireworks as the newly awakened supermassive black hole at the center of our galaxy, Sagittarius A*, reacts by emitting jets of extremely bright energetic radiation.”

“The Ocean Galaxy” –Many of Milky Way’s 4,000 Known Exoplanets May Be Water Worlds

"The Ocean Galaxy" --Many of the Milky Way's 4,000 Known Exoplanets May be Water Worlds?

 

“Plumes of water erupt from Europa and Enceladus, so we can tell that these bodies have subsurface oceans beneath their ice shells, and they have energy that drives the plumes, which are two requirements for life as we know it,” says Lynnae Quick, a NASA planetary scientist who specializes in volcanism and ocean worlds. Many of the more than 4,000 known exoplanets might resemble some of the watery moons around Jupiter and Saturn. “So if we’re thinking about these places as being possibly habitable, maybe bigger versions of them in other planetary systems are habitable too.”

Titanic Explosion in Andromeda –A Prelude?

 

Andromeda Galaxy

 

So far, we have had only close calls from gamma ray explosions so large, scientists have suggested, that if they occurred within our solar neighborhood (less than 1,000 light years) they could potentially trigger mass extinctions on Earth.

“Against All Odds” –NASA’s Planet-Hunting Tess Discovers a Unique Star System with Six ‘Suns’

TESS Mission

 

“The system exists against the odds,” said Brian Powell, a data scientist at NASA’s High Energy Astrophysics Science Archive Research Center about the source of starlight that was mysteriously brightening and dimming some 1,900 light-years away. The source, named TIC 168789840, is a system of three pairs of binary stars: three different stellar couplets revolving around three different centers of mass, but with the trio remaining gravitationally bound to one another and circling the galactic center as a single star system.

“The Phantom Universe” –Detected in Absolute Stillness of Our Solar System’s Center of Gravity

Signals from the Phantom Universe --"Detected in the Absolute Stillness of Our Solar System's Center of Gravity"

 

“Using the pulsars we observe across the Milky Way galaxy, we are trying to be like a spider sitting in stillness in the middle of her web,” says Vanderbilt’s Stephen Taylor, assistant professor of physics and astronomy and former astronomer at NASA’s Jet Propulsion Laboratory (JPL) about the location of absolute stillness in our solar system, the center of gravity with which to measure the gravitational waves that signal the existence of the invisible paradoxes we call black holes, which have no memory, and contain the earliest memories of the universe.
