After observing what we thought was just a big asteroid in the asteroid belt, a team of astronomers now thinks this might qualify as a dwarf planet. And scientists had the chance to directly observe the collision of two neutron stars for the first time. SciShow has a spinoff podcast! It's called SciShow Tangents.

According to a report by Digital Trends, late last year, a team of astronomers discovered what was then the most distant body observed in our solar system, nicknamed FarOut, while searching for the mysterious Planet Nine. Now, the team has reportedly discovered an even more distant object they have dubbed "FarFarOut." Astronomer Scott Sheppard found himself with located an object which is a massive 140 times further away from the sun then the Earth is, or 140 astronomical units. Digital Trends reports that is approximately 3.5 times the distance from the sun as Pluto, and further than FarOut’s distance of 120 AU. https://www.digitaltrends.com/cool-tech/farfarout-distant-object-solar-system/ http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Ceres is the largest so-called asteroid within the Asteroid Belt between Mars and Jupiter. First discovered in 1801, this England-sized dwarf planet may be small, but it has been labelled by scientists as a "chemical factory"; and a 2017 discovery found that the planet does indeed have several key ingredients for carbon-based primitive life as we know it. With upwards of 200M KM of water, and a vapour-rich atmosphere, Ceres may well be home to, or have been home to, very primitive species of life. So, what are we waiting for?

This series has been great, and I've learned so much about the universe while making these 12 episodes, and I've also learned incredible amounts about what it takes to be a good YouTuber with such high returns on episodes like the Bootes Void and the CMB Cold Spot. Space is now a key part of my channel, and will be for the foreseeable future- potentially forever. I can't wait to see what 2019 holds for the channel- and I'm willing to bet space and space videos, especially OOTW, will be an absolutely essential component in achieving whatever goals may come in the year ahead. Until then, happy new year, and thank you for watching and enjoying this series that is such a pleasure for me to produce. - Sam

For the first time, an object in our solar system has been found more than 100 times farther than Earth is from the sun.

It's believed to be the farthest known object in our solar system.

It's been a busy coupe of days, with minor planets out in strange orbits and serious data suggesting that a moon the size of Neptune might be in orbit around an exoplanet larger than Jupiter The models were generated with Universe Sandbox2 https://www.humblebundle.com/store/universe-sandbox-squared?partner=szyzyg&charity=61469

The small club of known dwarf planets orbiting our sun, which controversially includes Pluto, has just added another member. The International Astronomical Union’s Minor Planet Center announced Oct. 2 that researchers have discovered a new dwarf planet, 2015 TG387, that is roughly 186 miles across and likely made of ice. Owing to its discovery near Halloween on Oct. 13, 2015, the research team nicknamed the new object "the Goblin." "We think there could be thousands of small bodies like 2015 TG387 out on the Solar System’s fringes, but their distance makes finding them very difficult," David Tholen, an astronomer at the University of Hawaii, said in a press release. https://www.mnn.com/earth-matters/space/blogs/dwarf-planet-goblin-discovered-edge-our-solar-system http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Original air date: Friday, Sept. 7 at 11 a.m. PT (2 p.m. ET, 1800 UTC) Join JPL for a Science Chat to talk about the role of the agency's Dawn spacecraft in studying the beginning of our solar system, and the approaching end of its 11-year mission. Participants include: Jim Green, NASA chief scientist Carol Raymond, Dawn principal investigator at JPL Marc Rayman, Dawn mission director and chief engineer at JPL Follow us on your favorite social media platforms for updates @NASAJPL.

NASA’s Dawn spacecraft turned science fiction into science fact by using ion propulsion to explore the two largest bodies in the main asteroid belt, Vesta and Ceres. The mission will end this fall, when the spacecraft runs out of hydrazine, which keeps it oriented and in communication with Earth. For more info on the mission, visit https://dawn.jpl.nasa.gov
