“Provocateur” –Oumuamua Past Saturn on Its 10,000-Year Journey Through Solar System



Our infamous interstellar visitor, Oumuamua, the first macroscopic object of clear interstellar origin to be seen within Earth’s solar system after traveling through space for millions of years, has passed beyond Saturn’s orbit on 10,000 years for it to exit the solar system entirely. Astronomers at Yale and Caltech say that the enigmatic cosmic prodigy is best viewed as a comet with odd properties — not an alien probe, as has been vigorously debated.


Massive, Primordial Galaxies Discovered –“Untouched Across Cosmic Time”


New research has found that massive, ultracompact galaxies, which have several times more stars than the Milky Way, evolve in an accelerated way when compared to other galaxies in the universe. By understanding their properties , we can understand the eventual fate of all galaxies, including our own Milky Way.


Today’s Planet Earth Report –“Massive Buried Ice-Age Asteroid Crater to Ocean Floor is Dissolving”



The “Planet Earth Report” connects you to the day’s news headlines on the discoveries, people, and events changing our planet and the future of the human species.


“Exoplanet Hotspot?” –Planets Detected Orbiting Closest Star to the Sun


Only six light-years from Earth, Barnard’s star is among the nearby red dwarfs that represents an ideal target to search for exoplanets that could someday actually be reached by future interstellar spacecraft, says Steven Vogt, professor emeritus of astronomy and astrophysics at University of California, Santa Cruz. But the search for evidence of planets around this famous red dwarf star over the past 50 years has been unsuccessful.


The “Big Bang Galaxy” –Brightest in the Early Universe at 13 Billion Years Old Discovered to Harbor Carbon

Until summer of 2018, the earliest stars in the universe were thought to lack elements heavier than helium, such as carbon, the building block for life on Earth. In 2015, astronomers at Leiden University discovered an extremely distant galaxy called CR7, by far the brightest from its epoch ever seen, which matched their prediction. Three years later, with measurements using the ALMA telescope they found to their surprise, that the galaxy does have carbon after all, and even in normal concentrations.
