Astro Watch 18 Oct 2018, 22:51 UTC The Moon may be the key to unlocking how the first stars and galaxies shaped the early Universe. A team of astronomers led by Dr Benjamin McKinley at Curtin University node of the International Centre for Radio Astronomy Research (ICRAR) and the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) observed the Moon with a radio telescope to help search for the faint signal from hydrogen atoms in the infant Universe.
A Star Exploded as a Supernova and Then Collapsed Into a Neutron Star. But Only a Fraction of its Matter was Released18 Oct 2018, 20:46 UTC For almost a century, astronomers have been studying supernovae with great interest. These miraculous events are what take place when a star enters the final phase of its lifespan and collapses, or is stripped by a companion star of its outer layers to the point where it undergoes core collapse. In both cases, this event usually leads to a massive release of material a few times the mass of our Sun. However, an international team of scientists recently witnessed a supernova that was a surprisingly faint and brief. Their observations indicate that the supernova was caused by an unseen companion, likely a neutron star that stripped its companion of material, causing it to collapse and go supernova. This is therefore the first time that scientists have witnessed the birth of a compact neutron star binary system.
SPACE.com 18 Oct 2018, 15:30 UTC A monthslong journey. Docking on a faraway moon. What scenarios would make a human voyage to Mars possible? In late September, four experts participated in an hourlong conversation about what a mission to Mars would actually look like. "An Evening with Trailblazers — Are We Going to Mars?" took place at the Rensselaer Polytechnic Institute in Troy, New York, on Sept. 26.
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.
