“Proof?” –‘Oumuamua-Like’ Interstellar Object Struck Earth in 2014

Oumuamua Interstellar Object


Interstellar meteors may be common, and could potentially help life travel from star to star throughout the Milky Way, according to Harvard astronomer’s Amir Siraj and Avi Loeb who report that they have uncovered possible evidence of an extrasolar object striking the Earth back in 2014 from their study of the Center for Near-Earth Object database. They were searching the data for telltale objects that traveled faster than normal, suggesting that it was likely ejected out of an alien star system.


“Terminator Habitable Zone” –Alien Star-System Planets Face Death-Stream of High-Energy Particles

Trappist-1 Habitable Planets


“The flux of these particles in the TRAPPIST-1 system can be up to 1 million times more than the particles flux on Earth,” said Federico Fraschetti with the University of Arizona’s Lunar and Planetary Laboratory.


“A Forgotten World” –Apocalypse of the ‘Great Dying’ Gave Rise to the Dinosaurs

End of Permian Epoch


The evolutionary pruning shears of the Permian, a series of extinctions, including the Judgment Day at the period’s close known as the Great Dying that killed off more than 95 percent of life on Earth, cut the blossoming tree of life down to only a branch or two of mammal forerunners, including that of our ancestors. This is the forgotten world of the Permian epoch, the supercontinent of Pangaea, inhabited by our bizarre and formidable cousins, long overshadowed by the epic reign of the dinosaurs that followed.


“We’ve Pinpointed It” –Emergence of the ‘Modern’ Cosmos

Early Cosmos


The neutral hydrogen gas that filled the universe during the first few hundred million years after the Big Bang tended to absorb ambient light, leading to what cosmologists and science fiction authors poetically call the universe’s “dark ages.” Although the cosmos was filled with a diffuse ambient light from the cosmic microwave background (CMB) — the so-called afterglow of the Big Bang — this neutral gas absorbed it at specific wavelengths.


Cassini’s Last Flyby –“Titan’s Mystery World of Liquid Hydrocarbons”



“Every time we make discoveries on Titan, Titan becomes more and more mysterious,” said Marco Mastrogiuseppe, Cassini radar scientist at Caltech in Pasadena, California. “It is as if you looked down on the Earth’s North Pole and could see that North America had completely different geologic setting for bodies of liquid than Asia does,” added Jonathan Lunine, Director of the Center for Astrophysics and Planetary Science at Cornell University.


“Really Clear Signals” –Nearby Star System Harbors Earth-Sized Planet

TESS Exoplanet


“There was quite some detective work involved, and the right people were there at the right time,” said lead author Diana Dragomir of MIT’s Kavli Institute for Astrophysics and Space Research about the discovery of a nearby system that hosts the first Earth-sized planet by NASA’s Transiting Exoplanets Survey Satellite (TESS). “But we were lucky, and we caught the signals, and they were really clear.”


“The Last Photon Orbit” –Milky Way’s Supermassive Black Hole ‘On Deck’ for the EHT

Supermassive Black Hole


When it’s completed, the picture of the Milky Way’s supermassive black hole, Sagittarius A* (Sgr A*), is an image sure to equal the famous “Earthrise” photo taken by Apollo 8 astronaut Bill Anders in December 1968. The obvious target for the Event Horizon Telescope, the team hopes to get imagery of our supermassive black hole soon, said Shep Doeleman, Director, Event Horizon Telescope following last week’s release of the first ever image of Galaxy M87’s gargantuan black hole.
