Astronomers discover 6 possible new exomoons
Astronomers from Western University in Canada have discovered six more possible exomoons orbiting distant exoplanets, in data from the Kepler Space Telescope.
At least 2 super-Earths orbit this red dwarf star
Astronomers from the University of Göttingen in Germany have discovered two, and possibly three, super-Earth exoplanets orbiting the nearby red dwarf star Gliese-887.
Higher concentration of metal in Moon’s craters provides new insights to its origin
There has been considerable debate over how the Moon was formed. The popular hypothesis contends that the Moon was formed by a Mars-sized body colliding with Earth’s upper crust which is poor in metals. But new research suggests the Moon’s subsurface is more metal-rich than previously thought, providing new insights that could challenge our understanding of that process.

How dust could make some exoplanets more habitable
A new study from scientists in the UK suggests that atmospheric dust could increase the habitability of some exoplanets, especially those orbiting red dwarf stars.
New materials of perovskite challenge the chemical intuition
(Institute of Physics, Chinese Academy of Sciences) Materials scientists have synthesized a new type of perovskite–one of the most common crystal structures of materials deployed for a range of uses, from superconductors to photovoltaics–that goes against conventional thinking about how such structures behave at extreme pressures such as those that exist deep in the Earth.
Asteroid Day, June 30, live from Luxembourg
The 6th annual Asteroid Day will be held as a digital event on June 30, 2020. It’ll feature presentations with experts, panel discussions, and question-and-answer periods. Here’s how to participate.
Precise measurement of liquid iron density under extreme conditions
(Kumamoto University) Using the large synchrotron facility SPring-8 in Japan, scientists from Kumamoto University and the University of Tokyo, with collaborators from other institutes, have measured the density of liquid iron–the main component of rocky planet cores–under conditions similar to the Earth’s liquid core: 1,000,000 atmospheres and 4,000 degrees Celsius. Accurate density measurements of liquid iron under such extreme conditions are very important for understanding the chemical make-up of our planet’s core.
New Exotica Catalog will help guide search for ET
“What if extraterrestrial intelligences are not like us, but are found in the frigid reaches of the outer solar system, the extreme gravity of neutron stars, the brilliant cores of active galaxies, or the hearts of the richest galaxy clusters?”
