Interstellar Interloper 2I Borisov After the 2017 detecton of 1I/’Oumuamua, comet 2I/Borisov has become the second recognized interstellar interloper. Like ‘Oumuamua, Borisov’s measured hyperbolic trajectory and sp…
York teacher receives top astronomy honour A SCIENCE teacher from a York school has received a prestigious honour from the Royal Astronomical Society.
Gas 'waterfalls' might be feeding atmospheres of young planets The finding will help astronomers understand how new planets collect the gases that make up their atmospheres.
Girl Crush Last Sunday, our corner of the night sky was graced with a full moon called a "Tiny Hunter". Tiny, because the moon was at the furthest point in its elliptical orbit. Hunter, because this time of year harvested fields leave few places for animals to hide.
Solar system roundup planned at next Nanaimo Astronomy Society meeting 24 meeting guest speaker explores current and future missions to the planets.
NASA reveals new spacesuits designed to fit men and women These two new spacesuits will help the space agency put astronauts back on the surface of the Moon, enhance their mobility, and keep them safe along the way.
The Mystery of Titan's Sand Dunes - "We Don't Know How They Got There" "Bottom line, we don't know exactly what the sand is and we don't know how it got there," says Ralph Lorenz at John Hopkins University. We know very little about Titan's surface, which is why NASA's Dragonfly mission will land near the dunes in 2036 searching for the building blocks of life.
Space transport roundup - Oct.17.2019 A sampling of recent articles, videos, and images dealing with space transport :. ** Rocket Lab launches ninth Electron rocket with Astro Digital satellite: Rocket Lab successfully launches ninth Electron mission, deploys payload to highest orbit yet - Rocket Lab.
"I Talk to It Every Day": Students are Vital Members of LightSail 2 Team More than 50,000 people supported LightSail 2. But only one person can talk to the spacecraft at a time, and it's often a student.
Insight & Curiosity on Mars - "New Image of Human Footprint in the Solar System" The powerful HiRISE camera which takes pictures that cover vast areas of Martian terrain while being able to see features as small as a kitchen table, has been monitoring InSight's landing site in the Elysium Planitia region of the Red Planet for changes to the surface, such as dust-devil tracks.
More Interstellar Visitors? With a new generation of telescopes able to study these interstellar travelers in more detail, it looks like we'll be getting a whole new look at distant star systems and their planetary processes. You can read more about Laughlin and Rice's work in their paper.
2019-2020: Mars Until it Retrogrades Mars begins an apparition that takes it to an opposition on October 12, 2020, 808 days following its 2018 perihelic opposition. The opposition, that will be highlighted in a future issue, brings Mars to its closest approach about a week before opposition.
Revolutionary New Detector Made From Graphene for Next Generation of THz Astronomy Scientists from Chalmers University of Technology have exhibited an identifier produced using graphene that could alter the sensors utilized in cutting edge space telescopes. The discoveries were as of late distributed in the logical diary Nature Astronomy.
Hubble observes an alien visitor: the comet 2I/Borisov When the news was announced that a comet from another solar system - called 2I/Borisov - was passing through our own solar system, one of my first thoughts was, I wonder how long it'll be before Hubble takes a look at it? It turns out the answer is about six weeks.
The Age of Aquarius The lyrics to the song "Aquarius / Let the Sunshine In" were based on the astrological belief that the world would soon be entering the "Age of Aquarius", an age of love, harmony, understanding, sympathy, trust, different from the current "Age of Pisces".
Moons of Saturn On July 29, 2011 the Cassini spacecraft’s narrow-angle camera took this snapshot and captured 5 of Saturn’s moons, from just above the ringplane. Left to right are small moons Janus and…

Interstellar Comet Borisov "Indistinguishable" from Solar System Comets The solar system's newest interstellar visitor, Comet 2I/Borisov, looks remarkably familiar. A new study characterizing the comet revealed details, such as its nucleus size and gas distribution, that bear a striking resemblance to the icy population of the outer solar system.
2I/Borisov: Another Interstellar Visitor Flashes By Do they do the same thing at other stars? This comet's data will help answer that and other questions. Astronomers know the general properties of stars. They can deduce some information about their planetary systems just by studying orbital characteristics of the star and its planets.
The Female Spacewalk is Back! The all-female spacewalk, once cancelled, will launch this Thursday or Friday! A malfunctioning battery on the ISS is causing critical issues, meaning Jessica Meir and Christina Koch will be sent up to replace the old unit with a new one. This isn't the first malfunctioning unit, as one had also failed this year.
Supermassive Black Hole Cloud - "Unveils Their Rapid Growth in the Early Universe" When astronomers used the Atacama Large Millimeter / submillimeter Array to study this cloud in more detail, they made an unexpected discovery that could explain why supermassive black holes grew so rapidly in the early Universe.

"Up to Thousands of Years" - Circuits of Stars Orbiting Supermassive Black Holes At the center of the galaxy, millions of stars whirl in orbits around a supermassive black hole that can take anywhere from a few hours for stars close to the event horizon of the black hole to thousands of years for their distant neighbors, according to a new study that included scientists at the Institute for Advanced Study.
Autumn Comets, Mira's Eye & The Orionid Meteor Shower Four comets, a famous variable star, and sprinkles of dust from Halley's Comet are highlights of the October sky. I hope you had the opportunity to observe C/2018 W2, the brightest comet of the summer and fall.
