Scientists Find Organics on Ceres: There are two reasons the result is interesting. One, Ceres also has tons of water ice, plus carbonates and salts. The addition of organic material makes the dwarf planet a promising environment for prebiotic chemistry. Two, the organics don’t seem to have been delivered by impacts — no clear cause-and-effect with particular craters, plus a hit probably would have distributed the stuff in diluted form along with other debris. Not to mention there’s other, clearly native material mixed in. Instead, the organics likely come from Ceres itself. READ MORE
Three articles about Sol, our nearest star:
If the Sun goes spotless in decades to come, as some scientists are predicting it might, what does it mean for Earth? Scientists are studying the past to predict the future of space weather. READ MORE
Meteorites Date Demise of Solar Nebula: A study of ancient meteorites has refined the date for the dissolution of the solar nebula, the cloud of dust and gas that shrouded our Sun in its earliest days. READ MORE
How researchers use solar pressure to study our own star — and maybe reach interstellar space: The same pressure that could propel us to the stars may explain quirks in the Sun’s behaviour…. the Breakthrough Starshot initiative announced by billionaire Yuri Milner in 2016 aims to use giant lasers to launch swarms of tiny spacecraft on interstellar voyages at speeds of roughly 20 percent that of light to reach the nearest star system to the sun, Alpha Centauri, in approximately 20 years, give or take.

NASA is enlisting the public to find Planet Nine: Although it’s proposed as a way to find Planet Nine, the Backyard Worlds program may also help find asteroids near Earth, faint dwarf planets in the outskirts of the solar system, and failed stars within a few dozen light years of us, all of which appear faint to the naked eye but will still give off heat in infrared.

High school students identify an ultra-rare star: This newly-discovered variable is one of only seven of its kind known in our galaxy. READ MORE
How Islamic scholarship birthed modern astronomy: While Europe was in an intellectual coma, the Islamic empire which stretched from Moorish Spain, to Egypt and even China, was entering their “Golden Age”. READ MORE especially if Hidden Figures has interested you in the role of women scientists.
Many schools and mosques around this time were overseen and managed by Muslim women who themselves had been educated in subjects ranging from literature to algebra, a form of math also perfected by Islam. One of the most well known astronomical tools called an Astrolabe was created by the Greek thinker Hipparcus but was perfected by islamic scientists, particularly women.
METEORS FROM HALLEY’S COMET: A radar in Canada has detected radio echoes coming from the constellation Aquarius. This is a sign that the annual eta Aquarid meteor shower is underway. In the days ahead ahead our planet will cross a network of debris streams from Halley’s Comet, producing a drizzle of eta Aquarids numbering 10 to 30 meteors per hour in the northern hemisphere and perhaps twice that number in the southern hemisphere. Usually, the eta Aquarid shower peaks around May 6th. This year, there might be an additional enhancement on May 4th or 5th.
