Will We Discover Life-Bearing Alien Moons in the Coming Decade?

 

NASA Exomoon

 

“There are currently 175 known moons orbiting the eight planets in our solar system. While most of these moons orbit Saturn and Jupiter, which are outside the Sun’s habitable zone, that may not be the case in other solar systems,” said Stephen Kane, an associate professor of planetary astrophysics and a member of the University of California Riverside’s Alternative Earths Astrobiology Center about the life-bearing potential of moons of planets beyond our solar system. “Including rocky exomoons in our search for life in space will greatly expand the places we can look.”

Type 1a Supernova

 

“After having monitored tens of thousands of galaxies, we know there are other discoveries waiting to happen. Either faint objects, objects that change quickly, or things we do not even know about yet. The search is still going on!” wrote astrophysicist and cosmologist, Brad Tucker, currently a Research Fellow at the Research School of Astronomy and Astrophysics, Mt. Stromlo Observatory at the Australian National University, in an email to The Daily Galaxy about undiscovered gems in the Kepler Mission archives. Tucker is one of the leads of the Kepler Extra-Galactic Survey, KEGS, a Kepler Space Telescope Key Program, to understand why and how stars blow.

Antarctica Climate Change

 

“As we put more greenhouse gases into the atmosphere and temperatures rise, we are quickly rewinding the climate clock to climate states not seen in human history,” wrote acclaimed University of Wisconsin paleo-climatologist Jack Williams in an email to The Daily Galaxy. “We can expect that over the next few decades, climates will most resemble those of the warm Pliocene, roughly three million years ago, or perhaps even the hothouse Eocene, 50 million years ago.”

The center of our Galaxy has been intensely studied for many years, but it still harbors surprises for scientists. A snake-like structure lurking near our galaxy’s supermassive black hole is one of the more intriguing  discoveries. “Part of the thrill of science is stumbling across a mystery that is not easy to solve,” said Jun-Hui Zhao of the Harvard-Smithsonian Center for Astrophysics,. “While we don’t have the answer yet, the path to finding it is fascinating.”
