Astro Bob 18 Oct 2018, 04:37 UTC A team of astronomers recently used the VIMOS instrument on ESO’s Very Large Telescope to identify a gigantic proto-supercluster of galaxies forming in the early Universe, just 2.3 billion years after the Big Bang. Researchers gave it the name Hyperion after the Greek Titan god of heavenly light. It’s the largest and most massive structure to be found so early in the formation of the universe and appears to be an evolving early supercluster.
David Reneke's World of Space and Astronomy 17 Oct 2018, 21:51 UTC The average star takes almost 10 million years to form, depending on the available mass in the surrounding area, which is why this new monster galaxy is so exciting for astronomers. Why is COSMOS-AzTEC-1 so different from our own galaxy, and what can it teach us about our interstellar home?

Centauri Dreams 17 Oct 2018, 16:40 UTC We’ve never found a ‘hot Jupiter’ around a star as young as CI Tau. This well studied system, some 2 million years old, has drawn attention for its massive disk of dust and gas, one that extends hundreds of AU from the star. But radial velocity examination recently revealed CI Tau b, a hot Jupiter that in and of itself raises questions. Couple that to the likelihood of three other gas giant planets emerging in the disk with extreme differences in orbital radii and it’s clear that CI Tau challenges our ideas of how gas giants, especially hot Jupiters, emerge and evolve.
Starts With a Bang! 17 Oct 2018, 14:01 UTC When you look out beyond the Milky Way today, as far as we’ve ever been able to see, there are galaxies absolutely everywhere. Even if you take a dark patch of sky without stars, galaxies, or any known matter at all, if you look deep enough, thousands upon thousands of galaxies will be your reward. All told, there are an estimated two trillion galaxies within the observable Universe, stretching for tens of billions of light years in all directions. Yet despite all the galaxies we’ve seen, never have we gone far enough back to encounter the very first ones ever made in the Universe. The current record-holder, despite its light arriving from when the Universe was only 400 million years old — 3% of its present age — is already evolved and full of old stars. The first galaxies come from a time before we’ve ever probed. But if we get lucky, we’ll get there soon. Here’s what those galaxies should be like.
Astrobiology Magazine 16 Oct 2018, 23:00 UTC Hundreds of scientists and Mars-exploration enthusiasts will convene in a hotel ballroom just north of Los Angeles later this week to present, discuss and deliberate the future landing site for NASA’s next Red Planet rover – Mars 2020.
Spaceflight Now 16 Oct 2018, 19:05 UTC Two minutes after launch aboard a Russian Soyuz rocket last week, NASA astronaut Nick Hague knew something had gone badly wrong.At the moment four strap-on boosters separated from the rocket’s core stage, he and Soyuz MS-10 commander Alexey Ovchinin were thrown violently from side to side and then plastered back in their seats as escape rockets fired to push their Soyuz capsule away from its malfunctioning booster.
Centauri Dreams 16 Oct 2018, 17:08 UTC It was back in 2012 that Eric Mamajek (University of Rochester) and team discovered a possible ring system around the star J1407 in lightcurves originally taken in 2007, spawning subsequent work with Leiden Observatory’s Matthew Kenworthy. And what a ring system it would be if confirmed. The diameter, based on the lightcurve, would be nearly 120 million kilometers. This would be a ring system nearly 200 times larger than the rings of Saturn, one containing an Earth’s mass of dust particles, and in early studies, one housing over thirty separate rings.
