The Indian Space Research Organization (ISRO) is planning to launch a rocket to the moon. UPDATE: 2:28: The launch “has been called off for today,” the ISRO posted on Twitter. But when the re-scheduled launch happens, you can watch it live on two YouTube channels, on Twitter, Facebook, or webcast on the ISRO’s web site. TechCrunch has also embedded a livestreaming…

A connection between quantum correlations and spacetime geometry
Researchers of the Academy explore the consequences of locality for measurements distributed in spacetime. Their article has now been published in the Nature journal Quantum Information. …
Holes in the Universe sharpen cosmic measurements
Regions of the Universe containing very few or no galaxies—known as voids—can help measure cosmic expansion with much greater precision than before, according to new research. Source: https://phys.org/news/2019-07-holes-universe-sharpen-cosmic.html…
Is the Random Transiter weirder than Tabby’s Star?
Move over, Tabby’s Star. The Random Transiter may now be the weirdest star in the galaxy. Kepler data revealed 28 transits in front of this star in 87 days. What caused them? Multiple planets? A disintegrating planet? Alien megastructures? Source: https://earthsky.org/space/random-transiter-hd-139139-kepler-tabbys-star…
6 things to know about carbon dioxide
Scientists say increased carbon dioxide (CO2) in Earth’s atmosphere is causing global temperatures to warm – sea levels to rise – and storms, droughts, floods and fires to become more severe. Here are 6 things about CO2 you might not know. Source: https://earthsky.org/earth/6-things-to-know-carbon-dioxide-co2-greenhouse-gas…
NASA Announces New Dragonfly Drone Mission To Explore Titan
NASA announced Thursday that it is sending a drone-style quadcopter to Titan, Saturn’s largest moon. Dragonfly, as the mission is called, will be capable of soaring across the skies of Titan and landing intermittently to take scientific measurements, studying the world’s mysterious atmosphere and topography while searching for hints of life (Warning: source may be paywalled; alternative source) on the only…
Unusually high methane levels detected on Mars
Last week, the Curiosity rover detected its largest yet measurement of methane. It’s exciting because microbial life is an important source of methane on Earth, though it can also be created in other ways. Source: https://earthsky.org/space/unusually-high-methane-levels-detected-mars…
Atmospheric CO2 hits record high in May 2019
NOAA reports that carbon dioxide in Earth’s atmosphere continued its rapid rise in 2019, reaching the highest recorded levels in 61 years of observation last month. Source: https://earthsky.org/earth/atmospheric-co2-record-high-may-2019…
NASA Overcomes Military’s GPS Tweaks To Peer Inside Hurricanes
sciencehabit shares a report from Science Magazine: A constellation of eight microsatellites has harvested data that — if folded into the National Oceanic and Atmospheric Administration’s (NOAA’s) weather models — could have sharpened forecasts of several recent hurricanes, including Michael, a category-5 storm in October 2018. But progress was hard-won for scientists on NASA’s $157 million Cyclone Global Navigation Satellite System…
Today in science: Einstein’s triumph
May 29, 2019, is the 100th anniversary of a total solar eclipse, during which Sir Arthur Eddington observed the bending of light around the sun, thereby proving Einstein’s general relativity theory and catapulting Einstein into rock star fame.
