“Clouds of Rock” –Nighsides of Hot Jupiter Exoplanets

Hot Jupiter Darkside

 

Using data from the Spitzer Space and the Hubble Space telescopes, a new study by astronomers from the McGill Space Institute has found that the temperature on the nightsides of different hot Jupiters is surprisingly uniform at about 800°C, suggesting the dark side of these massive gaseous planets have clouds made of minerals and rocks.

Global Exoplanet Oceans –“May Support More Active, Abundant Life than Earth”

Exoplanet Ocean

 

“NASA’s search for life in the Universe is focused on so-called Habitable Zone planets, which are worlds that have the potential for liquid water oceans,” says Stephanie Olson at the University of Chicago. “But not all oceans are equally hospitable–and some oceans will be better places to live than others due to their global circulation patterns”.

“Alien Glow” –May Indicate Hidden Biospheres on Exoplanets

Hidden Biosphere

 

“This is a completely novel way to search for life in the universe. Just imagine an alien world glowing softly in a powerful telescope,” said lead author Jack O’Malley-James, a researcher at Cornell’s Carl Sagan Institute about ultraviolet radiation flares from red suns that might trigger a protective glow from life called biofluorescence.

“Milky Way’s First Intelligent Civilization?” –Zeroing In On Earth-like Planets

NASA TESS Mission

 

On February 5, 2019, The Galaxy reported that if advanced, space-faring alien life exist anywhere in the Milky Way, odds are they will live in the Galactic Habitable Zone (GHZ). And if they want to explore the Milky Way searching for other life-bearing planets, similar to Earth, they would only have to explore the GHZ, not the whole of the Galaxy.

“White Dwarf Ghosts” –Tuning In to Dead Exoplanet Radio Waves

White Dwarf Stars

 

Astronomers are planning to hunt for cores of exoplanets around white dwarf stars that have burnt all of their fuel and shed their outer layers, destroying nearby objects and removing the outer layers of planets by ‘tuning in’ to the radio waves that they emit for up to a billion years.
