Astronomers have discovered an extremely low-mass and dim dwarf galaxy around Andromeda. Called And 35, it's an Ultra-Faint Dwarf Galaxy (UFDG) and so far, the researchers have detected only 46 of its stars. Lambda-CDM predicts that there should be many UFDGs around galaxies like Andromeda and the Milky Way, so finding more of them is important. from Universe Today https://ift.tt/oShVU0C via IFTTT

We’ve reported on all kinds of wacky ideas for capturing and deorbiting space debris safely. From electric tethers to lasers, engineers and scientists have been trying everything they can think of to deal with the ever-increasing orbital debris problem. But one simple design keeps popping up over and over again - a net. A new paper from researchers at the Chinese Academy of Sciences and the University of Electronic Science and Technology of China details one of the most advanced net concepts yet - but whether we can actually build one remains to be seen. from Universe Today https://ift.tt/TZQGqNi via IFTTT

With new technologies come new opportunities. And that is especially true in astronomy - with every new advanced telescope we have the potential to see (or in some cases, listen) further and more clearly than we ever have before. That is certainly the case for the new Square Kilometre Array (SKA), which is currently undergoing a multi-year roll out phase. Despite that drawn out process, astronomers are already excited about its potential, and a new book chapter from Dr. Chenoa Tremblay and her co-authors details how this new technology could be used to answer one of the most fundamental questions - are we alone? from Universe Today https://ift.tt/EixFAhl via IFTTT

Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought.Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. from Universe Today https://ift.tt/80bYN6C via IFTTT

An international team involving over ten institutions, with a strong participation from ESO and INAF, has characterised TOI-201 c, the transiting brown dwarf with the longest period for which mass has been measured. The study, published today in Nature, reveals a compact, coplanar system in which the presence of a massive, eccentric object redefines the stability boundaries for the inner planets from Universe Today https://ift.tt/XLUc762 via IFTTT

Southwest Research Institute (SwRI) scientists are using a solar wind forecasting method combined with analytic and numerical heliosphere models to find out where the first plasma boundary of the outer heliosphere lies as NASA’s New Horizons spacecraft hurtles toward this mysterious region of space. from Universe Today https://ift.tt/rJE9zPj via IFTTT
