“Perhaps the most likely scenario for ‘life’ near a neutron star or black hole involves colonization … by robotic missions from a civilization around another nearby star,” astronomer James Cordes at Cornell University, told The Daily Galaxy. Cordes’ research focus includes neutron stars, pulsars, and the search for extraterrestrial intelligence. “Such a mission,” he notes, “would be very costly and might not be warranted given the power of remote sensing. However, an ancient but advanced civilization might afford such a luxury.”
The Milky Way’s bulge is the ancient and crowded central hub of our Galaxy. It contains about one quarter of the total stellar mass of the Milky Way and has a very different stellar environment than our solar neighborhood. The stellar densities are on average over 10 times higher and include both very young but mostly very old stellar populations.
Before life appeared on land some 400 million years ago, all life on Earth including the mind evolved in the sea. Astronomers have recently conjectured that blue exoplanets with endless oceans may be orbiting many of the Milky Way’s one trillion stars. In 2016, for example, Kepler astronomers discovered planets that are unlike anything in our solar system –a “water world” planetary system orbiting the star Kepler-62. This five-planet system has two worlds in the habitable zone — their surfaces completely covered by an endless global ocean with no land or mountains in sight.
We’re kicking off the week with intriguing stories from our Universe beyond–from exoplanets in the ancient, densely populated bulge of the Milky Way to the mystery of eternal brown dwarfs to the soon approaching, long awaited launch of the iconic Hubble spacecraft’s successor.
Another amazing week in our Universe beyond –from a new type of habitable planet to China’s plan for a spacecraft 30 times the size of the ISS to the new reality of UFOs and the detection of gravitational waves that could be from dark matter particles.
