Andromeda’s Newest Dwarf Galaxy is Extremely Dim 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. Universe Today Go to SourceRead More →

New Horizons Watches the Solar Wind as it Slows Down Where does the Solar System end and interstellar space begin? That’s a question scientists have been working to answer using spacecraft traveling out beyond the Sun’s influence. A team of researchers from the Southwest Research Institute led by Heather Elliott, is using the Solar Wind around Pluto instrument onboard New Horizons to track the solar wind in the outer reachers of the Solar System.

A New Net-Membrane Could Clean Up Some Tricky Space Debris 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.Read More →

The Square Kilometre Array Will Revolutionize the Hunt for Alien Life 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 answerRead More →

Nearby “Super Earth” Could Host Life After All 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.

Astronomers Characterize “Improbable” System Shaped by Brown Dwarf 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 Universe Today Go to SourceRead More →

In Anticipation of New Horizons Entering Interstellar Space, Researchers are Developing a Solar Wind Forecasting Method 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.

Bending Spacetime Reveals New Planet Hidden in Archived TESS Data NASA’s Transiting Exoplanet Survey Satellite (TESS) has captured evidence of a Jupiter-like world orbiting another star, using a trick straight out of Einstein’s relativity: gravitational microlensing. The technique marks a first for TESS, and opens up the possibility of a whole new category of planets the spacecraft might uncover. Universe Today Go to SourceRead More →

Astronomers Spot an Extremely Rare Galaxy Mega-Merger Scale in the universe is hard to understand from a purely human perspective. Many times the math just doesn’t sit well with our brains that evolved to capture and process data about the world around us rather than groking the complexities of stellar dynamics and galaxy mergers. But every once in a while astronomers find something that, if we can wrap our heads around the numbers, gives a sense of just how big the universe is. That is precisely what a new paper, available in preprint on arXiv from a group of astronomers led by Z.L. Wen ofRead More →

This Giant Planet Survived the Death of its Star Some planets can survive when their main sequence stars “die” and evolve into red giants. Astronomers have found several of them. One of them in particular is orbiting extremely close to its star, providing an opportunity to study it with the JWST to determine how it got there. Universe Today Go to SourceRead More →

An Extended Barrage of Asteroid Impacts Made Earth Too Hot to Form Continents New research shows that repeated impacts on Earth during the Hadean eon prevented thick and stable crustal material from forming. The heat from these impacts penetrated deep into the planet, and along with radiogenic heating, delayed the formation of a solid crust. Universe Today Go to SourceRead More →

A Supermassive Black Hole Gets Blamed for Quenching Star Formation Some of the most massive galaxies in the Universe appear to be missing a lot of stars. That seems unusual, since birthing stars is one of a galaxy’s main tasks as it grows. According to Xin “Cindy” Xiang of the University of Michigan, something is suppressing or quenching the births of stars in these and she thinks that black holes might be the culprit.

The Quiet Conversation Between Muscle and Gravity, and What Happens When It Stops Every muscle in the human body is, in a sense, in constant conversation with gravity, sensing load and responding accordingly to stay strong. Remove that conversation, as happens to astronauts in orbit, and the consequences unfold at a molecular level long before they become visible. New NASA-supported research is tracing exactly how that breakdown happens, using a purpose-built model that mimics weightlessness here on Earth. The surprising twist is where else this knowledge might apply Universe Today Go to SourceRead More →

A Star’s Death Throes Involves a Lot of Kicking When stars like the Sun reach the end of their lives, the textbook story has them puffing up and quietly shedding their outer layers to leave a white dwarf behind. A new model suggests it is far less serene than that. As dying stars eject mass asymmetrically, each burst delivers a tiny recoil, and over hundreds of thousands of years roughly ten thousand of these kicks add up to send the star drifting through space at a respectable speed. The idea neatly explains why wide binary star systems tend to fall apart once one star becomesRead More →

Galaxy Groups Hiding in the Universe’s Emptiest Places Even the universe’s emptiest regions, the vast voids that make up most of the volume of space, are not entirely empty. A new study using the CAVITY survey hunts for galaxy groups hiding within these voids, applying a friends of friends technique to chart how nearby galaxies cluster together despite the surrounding emptiness. The results paint a striking picture that most void galaxies actually live entirely solitary lives, yet where groups do form, they are small, loose and curiously indifferent to just how empty their void actually is. It raises a deceptively simple question that turns outRead More →

ESA Outlines High-Tech Lander Instruments for 2050 Enceladus Saturn’s moon, Enceladus, has become a prime solar system target for astrobiologists. This is because the small moon, which is just over 10 percent the diameter of Earth’s Moon, harbors a vast subsurface ocean beneath its icy crust. This subsurface ocean combined with the geysers at Enceladus’ south pole that discharges bits of this ocean into the void provides scientists with a treasure trove of opportunities for scientific research into whether Enceladus could harbor ingredients for life as we know it, or even direct evidence for life.

Habitable Worlds Targets in New Star Activity Catalog Searching for habitable worlds beyond our solar system consists of more than just having it orbit within its star’s habitable zone, which is the region where temperatures could be just right for liquid water to exist on the surface. On Earth, where water comprises approximately 75 percent of the planet’s surface, life is absurdly abundant. But what about the exoplanet’s star, specifically its activity and rotation? How could this influence how exoplanets are identified for current and future missions? Universe Today Go to SourceRead More →
