—European Southern Observatory: “Astronomers Find Missing Link for Water in the Solar System“
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected gaseous water in the planet-forming disc around the star V883 Orionis. This water carries a chemical signature that explains the journey of water from star-forming gas clouds to planets, and supports the idea that water on Earth is even older than our Sun.
“We can now trace the origins of water in our Solar System to before the formation of the Sun,” says John J. Tobin, an astronomer at the National Radio Astronomy Observatory, USA and lead author of the study published today in Nature.
—SciTech Daily: “Astronomers Uncover Black Hole Closer to Earth Than Ever Before“
Astronomers have discovered the closest black hole to Earth, the first unambiguous detection of a dormant stellar-mass black hole in the Milky Way. Its close proximity to Earth, a mere 1,600 light-years away, offers an intriguing target of study to advance understanding of the evolution of binary systems.
—New York Times: “The Moon May Get Its Own Time Zone“
What time is it on the moon? Since the dawn of the space age, the answer has been: It depends. For decades, lunar missions have operated on the time of the country that launched them. But with several lunar explorations heading for the launchpad, the European Space Agency has deemed the current system unsustainable. The solution, the agency said last week, is a lunar time zone.
