Largest problem....getting there to confirm.
Seriously, will all these discoveries, someone with a clever idea should be coming up with a practical FTL theory for a FTL drive so out species can got and check out all these planets within a reasonable amount of time.

Astronomers Are Now Hunting for Planet 9 and Planet 10:
"New research indicates there may be an undiscovered planet lurking in our solar system, in addition to the one we're already searching for. Astronomers are still hunting for evidence of a proposed ninth planet lurking somewhere in the outer reaches of our solar system. But now they have something else to search for. New research from the University of Arizona hints that there may be another planet out there, waiting for us to find it." See: http://www.popularmechanics.com/spac...for-planet-10/ |

Friends, I need your help. I was given a homework in the school to write an essay on astronomy. The theme is "Halley's Comet" I found one site Essayshark, online help for students. You can order any work there, but I'd like to write it myself. Can you give me good resources, please? Thank you in advance!

Are Galaxies Flowing Toward a Point Beyond Our Universe?:
"We all know that the universe is constantly in motion. Earth revolves around the sun, our solar system turns with the rest of the Milky Way galaxy, which in turn moves within a larger cluster of galaxies, and all of these components move away from other galaxy clusters as the universe expands. According to the theory of Hubble Flow, this expansion should be equal in all directions. But by studying a map of the Cosmic Microwave Background (CMB)—the remaining radiation from the big bang that invisibly coats the universe—astrophysicists discovered that some galaxy clusters seem to be moving toward a point that appears to be beyond the perceivable universe. They call this movement dark flow." See: http://www.popularmechanics.com/spac...ow-space-time/ |

Dark Matter and Energy Don't Exist: Astronomer Claims to
Solve Universe's Greatest Mysteries With New Model: "Dark matter and dark energy—the mystery forces believed to govern the universe— may not exist after all. In a newly developed model, astronomer André Maeder has found that neither of these concepts is needed for the universe to be expanding at an accelerating rate." "In the new study, published in The Astrophysical Journal¸ Maeder focuses on “scale invariance.” This is the concept that says a feature of an object will not change even if its length or energy scales are multiplied by a common factor."

Kepler’s forgotten ideas about symmetry help explain spiral
galaxies without the need for dark matter – new research: "The 17th-century astronomer Johannes Kepler was the first to muse about the structure of snowflakes. Why are they so symmetrical? How does one side know how long the opposite side has grown? Kepler thought it was all down to what we would now call a “morphogenic field” – that things want to have the form they have. Science has since discounted this idea. But the question of why snowflakes and similar structures are so symmetrical is nevertheless not entirely understood. Modern science shows just how fundamental the question is: look at all the spiral galaxies out there. They can be half a million light years across, but they still preserve their symmetry. How? In our new study, published in Scientific Reports, we present an explanation. We have shown that information and “entropy” – a measure of the disorder of a system – are linked together (“info-entropy”) in a way exactly analogous to electric and magnetic fields (“electromagnetism”). Electric currents produce magnetic fields, while changing magnetic fields produce electric currents. Information and entropy influence each other in the same way."

There’s Growing Evidence That the Universe Is Connected by Giant Structures:
"The Milky Way, the galaxy we live in, is one of hundreds of billions of galaxies strewn across the universe. Their variety is stunning: spirals, ring galaxies shaped like star- studded loops, and ancient galaxies that outshine virtually everything else in the universe. But despite their differences, and the mind-boggling distances between them, scientists have noticed that some galaxies move together in odd and often unexplained patterns, as if they are connected by a vast unseen force. Galaxies within a few million light years of each other can gravitationally affect each other in predictable ways, but scientists have observed mysterious patterns between distant galaxies that transcend those local interactions. These discoveries hint at the enigmatic influence of so-called “large-scale structures” which, as the name suggests, are the biggest known objects in the universe. These dim structures are made of hydrogen gas and dark matter and take the form of filaments, sheets, and knots that link galaxies in a vast network called the cosmic web. We know these structures have major implications for the evolution and movements of galaxies, but we’ve barely scratched the surface of the root dynamics driving them."

Scientists Found More Than 100 Tiny Worlds Hidden in the Solar System:
"A telescope looking for dark matter discovered 139 new minor planets lurking beyond Neptune's orbit, which could help scientists look for hidden planets in the outer solar system." See: https://www.vice.com/en_us/article/d...e-solar-system |

Ah! I like this. Just started the new Cosmos: Possible Worlds. Niel deGrasse Tyson for president of the world! He's got my vote, but Kim Jong-un won't like it.
Gonna share with you my favorite bit: TIMELAPSE OF THE FUTURE: A Journey to the End of Time https://www.youtube.com/watch?v=uD4izuDMUQA It's made by some of the worlds top scientists, it's got awesome visualization and acoustics. I've seen it countless of times, I don't think anyone, fan of the cosmos wouldn't like it, at least seeing it once. I suggest watching that with all lights out, in the middle of the night. It's worth it!

New study deepens the controversy over Planet Nine's existence:
"Is there a mysterious Planet Nine hiding in the outskirts of our solar system? While there've been hypotheses making such claims, a new study looks to disprove its existence. The research from astronomers at the University of Pennsylvania strikes at the heart of the clues that led some to believe such a planet was there. From 2014, astronomers have been suggesting various explanations for the behavior of so-called "trans-Neptunian objects" (eTNOs) that are farther from the Sun than Neptune. These rocks in the outer reaches were previously found to be clumped together, traveling in an elongated orbit, as reports New Scientist. One reason for that could be that they were pulled by the gravity of a giant planet that is five to 10 times the mass of Earth. One fascinating idea proposed about such a possible planet is that it may be responsible for the extinction of the dinosaurs, as it knocks catastrophic comets towards Earth when it passes through the Kuiper belt once every 27 million years. The new research shows, however, that there may not be any clustering trans- Neptunian rocks at all. The scientists used data from the Dark Energy Survey, carried out at a Chilean observatory. The University of Pennsylvania astronomer Pedro Bernardinelli, the lead author of the paper, thinks their data doesn't bode well for Planet Nine's probability."

A salty ocean found on the Dwarf Planet Ceres.
https://www.reuters.com/article/us-s...-idUSKCN2562HE Interesting. That's unexpected from what I recall about that asteroid belt object.
