The 1.8 Gigayear Planet Orbiting an Ancient Dying Star –“Hotspot for Advanced Life”

White Dwarf Planet

 

If we ever have contact with extraterrestrial life from outside our solar system, it will be intelligent, which may be the only thing we have in common with them. Life on our planet is carbon-based, but argues Oxford evolutionary-biologist Richard Dawkins, it’s not totally out of the question to have it based on silicon – robotic, machines in other words. “So if and when we meet, it’ll also transform our understanding of ourselves and the Universe we live in.”

“Satan’s Abode” -Exoplanet So Hot Molecules in Its Atmosphere are Torn to Shreds

Exoplanet KELT-9b

 

And we thought Venus was hot, with a surface temperature that melts lead. New observations of a bizarre world beyond our solar system, a massive gas giant –KELT-9b, an ultra-hot Jupiter three times the mass of our own Jupiter– is hotter than a star –a habitat so strange, that planetwide meltdowns tear apart the molecules that make up its atmosphere. A team of astronomers using NASA’s Spitzer space telescope has found evidence that the heat is so intense that molecules of hydrogen gas are likely ripped apart on the dayside of KELT-9b, unable to re-form until their disjointed atoms flow around to the planet’s nightside.

“Hot Jupiter” –Detected Spiraling Towards Its Fiery Doom

Hot Jupiter Exoplanet

 

 

Since its discovery in 1995, exoplanet WASP-12b, a “hot Jupiter,” has been spiraling towards its doom. Located 600 light-years away in the constellation Auriga, a Princeton-led team of astrophysicists has shown that the exoplanet is spiraling in toward its host star, heading toward certain destruction with less than a thousandth of that of Earth’s end, a mere 3 million years, before it meets its fiery demise.

ESA Launches CHEOPS –Mission: “Are We Alone?”

CHEOPS Launch

 

“Cheops will take exoplanet science to a whole new level,” said Günther Hasinger, the European Space Agency’s director of science about the world’s newest orbiting telescope whose name stands for CHaracterising ExOPlanet Satellite that launched early on Wednesday morning aboard a Soyuz-Fregat rocket from the European spaceport in Kourou, French Guiana. It was the second try after Tuesday’s first launch attempt was delayed and some equipment was replaced.

“They’re Out There” –Most Likely On Exo-Earths of Binary Star Systems

Alpha Centauri Star Systemm

 

“They’re out there,” goes the common quip about extraterrestrials. It would seem more likely to be true in light of a new study by astrophysicists at the Georgia Institute of Technology on planetary axis tilts that modeled a theoretical twin of Earth into other star systems called binary systems because they have two stars. They concluded that 87% of exo-Earths one might find in binary systems should have axis tilts similarly steady to Earth’s, an important ingredient for climate stability that favors the evolution of complex life.

“Are We Alone?” –New 3D-Models of Exoplanets Moves Us Closer to the Answer

M Dwarf Planet

 

“For most of human history, the question of whether or not life exists elsewhere has belonged only within the philosophical realm. It’s only in recent years that we have had the modeling tools and observational technology to address this question,” said Northwestern’s Howard Chen, future investigator in NASA Earth & Space Science & Technology and first author of the research team that is the first to combine 3D climate modeling with atmospheric chemistry to explore the habitability of planets around M dwarf stars, which comprise about 70% of the total galactic population.
