- 			 Astronomy AstronomyThe Milky Way’s black hole is constantly bubblingThe disc of plasma surrounding the black hole at the heart of the Milky Way is constantly emitting flares both large and small. 
- 			 Astronomy AstronomyCitizen scientists make cosmic discoveries with a global telescope networkOn balconies and in backyards, Wi-Fi–enabled telescopes are connecting astronomy enthusiasts across six continents. 
- 			 Astronomy AstronomyThe universe’s first supernovas probably produced waterWater may have formed less than 200 million years after the Big Bang, suggesting some conditions for life existed far earlier than previously thought. 
- 			 Astronomy AstronomySome of Earth’s meteors are probably coming all the way from a neighboring star systemThe triple star system is sending comets, asteroids and meteors our way, and the number of interstellar objects entering the solar system will rise. By Ken Croswell
- 			 Planetary Science Planetary ScienceAncient Mars wasn’t just wet. It was cold and wetMars may once have held enough water to fill oceans and form coastlines. The planet’s red dust contains water and likely formed in cold conditions. By Skyler Ware
- 			 Astronomy AstronomyA fast radio burst from a dead galaxy puzzles astronomersA blast of radio waves from the outskirts of an ancient galaxy challenges theories about what creates such bursts. 
- 			 Astronomy AstronomyA cosmic ‘Platypus’ might link two astronomical mysteriesA flash of light called the Platypus has hallmarks of a mid-sized black hole shredding a star and a type of burst thought to be a stellar explosion. 
- 			 Astronomy AstronomyGalactic chaos at cosmic noon may have stunted Milky Way planet formationHigh radiation during a time of frenzied star formation in the Milky Way left one stellar population with few chances to form planets, a study reports. 
- 			 Planetary Science Planetary ScienceA crumbling exoplanet spills its gutsAstronomers have determined the internal composition of a distant, disintegrating planet for the first time. 
- 			 Cosmology CosmologyHow we might finally find black holes from the cosmic dawnAfter decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter. 
- 			 Particle Physics Particle PhysicsScientists are building underwater neutrino telescopes in the MediterraneanThe KM3NeT telescopes, currently under construction, will catch high-energy neutrinos that could reveal secrets of the cosmos. 
- 			 Space Space50 years ago, astronomers saw the surface of a distant star for the first timeIn the 1970s, technological advances let scientists peer through stars’ atmospheres. Now, scientists can measure roiling gas in the stars themselves.
