Universe Today 24 Aug 2020, 11:52 UTC Venus has been garnering a lot of attention lately, though primarily in the scientific community as the last Hollywood movie about the planet was released in the 1960s. This is in part due to its dramatic difference from Earth, and what that difference might mean for the study of exoplanets. If we can better understand what happened during Venus’ formation to make it the hell scape it is today, we might be able to better understand what truly constitutes the habitable zone around other stars.
Universe Today 21 Aug 2020, 17:31 UTC When it comes to places with the potential for habitability, Venus isn’t usually considered on that list. The hot, greenhouse-effect-gone-mad neighboring planet with a crushing surface pressure and sulfuric acid clouds certainly isn’t friendly to life as we know it, and the few spacecraft humanity has sent to Venus’ surface have only endured a few minutes.

Bad Astronomy 20 Aug 2020, 13:00 UTC To a large extent, most of the Universe is hydrogen. It's the simplest element, just a proton and an electron (and honestly, the electron is optional), and it came out of the fires of the Big Bang. Roughly 75% of the non-dark Universe is hydrogen by mass, with 25% being helium, and the tiny remainder is everything else, basically a roundoff error.
Cosmology & Space Exploration 19 Aug 2020, 11:42 UTC 95 nearby brown dwarfs have been discovered thanks to a collaboration between volunteers and professional scientists.
This Distorted Circle is Actually a Galaxy That Looked Very Similar to the Milky Way, Shortly After the Big Bang19 Aug 2020, 11:19 UTC The most widely accepted cosmological view states that the first galaxies formed about 380–400 million years after the Big Bang. These were made up of young, hot stars that lived fast and died young, causing the galaxies themselves to be turbulent. At least, that was the theory until a European team of astronomers observed a galaxy 12 billion light-years away that closely resembled the Milky Way.
Centauri Dreams 18 Aug 2020, 16:06 UTC Studies of interstellar interloper ‘Oumuamua move at lightning pace, to judge from a recent exchange on hydrogen ice. A study by Greg Laughlin and Darryl Seligman (both at Yale) just published in June, has now met a response from Thiem Hoang (Korea University of Science and Technology, Daejeon) and Harvard’s Avi Loeb. The issue is significant because if, as Laughlin and Seligman argued, ‘Oumuamua were made of hydrogen ice, then the outgassing that drove its slight acceleration would not have been detectable. At least one mystery solved.
Universe Today 18 Aug 2020, 13:47 UTC Humanity is still a long way away from a fully artificial intelligence system. For now at least, AI is particularly good at some specialized tasks, such as classifying cats in videos. Now it has a new skill set: identifying spiral patterns in galaxies.
