3 Earth-sized exoplanets found just 12 light-years away One of the planets may be in its star's habitable zone, and a fourth planet is hinted at as well.
8 new repeating fast radio bursts offer new opportunities for insights A telescope called CHIME has just quintupled the number of known repeating fast radio bursts, giving researchers more of these mysterious signals to unravel.
Space transport roundup - Aug.21.2019 A sampling of recent articles, videos, and images dealing with space transport :. ** 8th Electron launch a success for Rocket Lab on August 19th. Four satellites were successfully deployed. From Rocket Lab:.
Why do we still believe in 'lunacy' during a Full Moon? Blaming the Full Moon for strange behavior is a time-honored tradition. In the first century AD, the Roman philosopher Pliny suggested that the Full Moon caused more dew to form, which led to increased moisture in the brain, and that, he said, led to madness.
A Problem of Dimensions We've more-or-less sorted out who will be teaching what next term in the Department of Theoretical Physics at Maynooth University next term and I'll be taking over the Mathematical Physics module MP110, which is basically about Mechanics with a bit of of special relativity thrown in for fun.
Planet Earth Report - "Anthropocene Not an Epoch to Greenland as the Future" The "Planet Earth Report" connects you to headline news on the science, technology, discoveries, people and events changing our planet and the future of the human species. How walking helped humans take over the planet - We are all fitter for a good walk - and we become smarter just by standing up.
Astronomy news: How to see Orion the Hunter at night? Constellation to light up August sky ASTRONOMY enthusiasts across the globe are excited about the arrival of Orion the Hunter – the most beautiful and instantly recognisable constellation to grace the night skies.
"Interstellar" - Extraterrestrial Particles Unveiled in Antarctica A mere blip in our 250 million-year orbit through the Milky Way. A team of scientists hauled 500 kilograms of fresh snow back from Antarctica, melted it, and sifted through the particles that remained. Their analysis yielded a surprise: The snow held significant amounts of iron-60 that isn't naturally produced on Earth.
"Catch a falling star and put it in your pocket…" Today’s Word of the Day is misnomer which means, “a wrong name or inappropriate designation.” As an astronomy buff, one of my favorite misnomers is “falling star.” It&…
Earth's last magnetic pole flip took 22,000 years to complete In volcanic rock, the Earth's magnetic field is recorded as lava cools; iron in the rock orients itself to the Earth's field, and so the geomagnetic field strength and direction can be measured. Radioactive isotopes can be used to date the timings of these events.
Column: Maunakea vital to science of astronomy As the former director of the Institute for Astronomy of the University of Hawaii, and the current director of science of the European Space Agency, I would like to give an outside / inside view on the conflict about the Thirty Meter Telescope in Hawaii.
The Orion You Can Almost See Do you recognize this constellation? Although it is one of the most recognizable star groupings on the sky, this is a more full Orion than you can see — an Orion only revealed with long expos…
Poetry Day and the 2017 Eclipse Several unreliable sources list August 21 as Poetry Day. This poem is by Barry Middleton. August 21, 2017Once feared as omen from an angry god, the sun’s eclipse gives cause to celebrate. Wit…
NASA Ignores "Attempt No Landing There" Warning - Greenlights Europa Mission Clarke also famously warned against a mission to explore the most intriguing of Jupiter's 79 moons, which has now been given the green light to proceed to the final stages of development of NASA's Europa Clipper Mission.
Astronomy magazine's Space & Beyond subscription box It was at the dawning of a new golden age of astronomy, full of scientific breakthroughs, from the discovery of dark energy and how the universe will end, to fresh clues about how life started on Earth - and, just maybe, spread across the universe.
Second giant planet found around nearby star Beta Pictoris Apai says, "A violent past encounter of the two super-Jupiters may be the source of the mess in this planetary system." Evidence for the new planet, Beta Pictoris c, was found using the radial velocity method, which indirectly detects a planet by measuring how its host star wobbles around the system's overall center of mass.
AAS Board Reflections: Adam Burgasser In order to familiarize the astronomy community with the AAS Board and encourage participation, the CSWA created a Reflection Survey for outgoing AAS Board members to complete after their terms ended in June. Over the coming weeks, we will feature the responses we've received on the Women in Astronomy blog.
A brief astronomical history of Saturn's amazing rings But Saturn perplexed him. Peering at the planet through his telescope, it first looked to him as a planet with two very large moons, then as a lone planet, and then again through his newer telescope, in 1616, as a planet with arms or handles.

Image Sleuth Spots Tiny "Churyumoon" Around Rosetta's Comet A tiny, 4-meter fragment dubbed Churyumoon has been spotted orbiting Comet 67P / Churyumov-Gerasimenko, which the Rosetta mission visited from 2014 to 2016. Is this the smallest moon discovery yet?
Space September As a science fiction fan of sorts and a nerd with a general interest in exotic scientific subjects like quantum physics, astral dynamics and so on of course I love myself some space-y stuff even in LEGO form. This month's issue of the LEGO City magazine caters just for that.
Quantum World of Black Holes - "Contorting the Fabric of Spacetime" This project can shed light on the fundamental laws that govern the cosmos on both unimaginably small and vastly large scales.
Where is the Tropic of Capricorn? A well-traveled geophysicist recounts his curious findings at a prominent geographic benchmark in the Southern Hemisphere. Most globes of Earth show four dashed lines that, aside from the equator, denote special latitudes related to the seasons.
