Two Families of Comets Found Around Nearby Star - Biggest census ever of exocomets around Beta Pictoris

The HARPS instrument at ESO’s La Silla Observatory in Chile has been used to make the most complete census of comets around another star ever created. A French team of astronomers has studied nearly 500 individual comets orbiting the star Beta Pictoris and has discovered that they belong to two distinct families of exocomets: old exocomets that have made multiple passages near the star, and younger exocomets that probably came from the recent breakup of one or more larger objects. The new resul

Rosetta Reignites Debate on Earth's Oceans - NASA Science | Space & Time | Scoop.it
A popular theory holds that ocean water was brought to Earth by the ancient impacts of comets and asteroids. However, new data from the European Space Agency’s Rosetta spacecraft indicate that terrestrial water did not come from comets like 67P/Churyumov-Gerasimenko.

Spooky Alignment of Quasars Across Billions of Light-years - VLT reveals alignments between supermassive black hole axes and large-scale structure

Spooky Alignment of Quasars Across Billions of Light-years - VLT reveals alignments between supermassive black hole axes and large-scale structure | Space & Time | Scoop.it
New observations with ESO’s Very Large Telescope (VLT) in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the central supermassive black holes in a sample of quasars are parallel to each other over distances of billions of light-years. The team has also found that the rotation axes of these quasars tend to be aligned with the vast structures in the cosmic web in which they reside.
