Solar system formation in two steps An international team of researchers from the University of Oxford, LMU Munich, ETH Zurich, BGI Bayreuth, and the University of Zurich discovered that a two-step formation process of the early Solar System can explain the chronology and split in volatile and isotope content of the inner and outer Solar […]
Much of Earth’s nitrogen was locally sourced Where did Earth’s nitrogen come from? Rice University scientists show one primordial source of the indispensable building block for life was close to home. phys.org Go to Source
Scientists find black holes could reach ‘stupendously large’ sizes A recent study suggests the possible existence of ‘stupendously large black holes’ or SLABS, even larger than the supermassive black holes already observed in the centers of galaxies. phys.org Go to Source
Rocks show Mars once felt like Iceland Once upon a time, seasons in Gale Crater probably felt something like those in Iceland. But nobody was there to bundle up more than 3 billion years ago. phys.org Go to Source
Astronomers see whirlwind around possible exoplanet in the making An international team of astronomers led by researchers from the Netherlands has discovered a whirlwind of dust and debris in orbit around a young star. It is possible that a planet is forming within the debris. The scientists made the discovery during the time that designers […]
A Habitat at Ceres Could be the Gateway to the Outer Solar System A new proposal from the inventor of the E-sail shows how we could create an Earth-like space habitat around Ceres, which could be a gateway to the rest of the Solar System The post A Habitat at Ceres Could be the Gateway […]
New Drones for Exploring Mars are Getting Tested in Iceland It’s looking more and more like the future of space exploration could involve drones in a big way. We’ve already seen it here on Earth, where all kinds of flying drones are used by all kinds of people for all kinds of things. Drones are […]
Fornax A galaxy investigated with AstroSat Using the AstroSat spacecraft, Indian astronomers have performed an imaging and spectroscopic study of the Fornax A galaxy. Results of the study, published January 13 on the arXiv preprint server, provide more clues on the properties of the galaxy and ultraviolet emission from this source. phys.org Go to Source
Saturn’s tilt caused by its moons Two scientists from CNRS and Sorbonne University working at the Institute of Celestial Mechanics and Ephemeris Calculation (Paris Observatory—PSL/CNRS) have just shown that the influence of Saturn’s satellites can explain the tilt of the rotation axis of the gas giant. Their work, published on 18 January 2021 in the […]
Astronomers Confirm That Darksat is About Half as Bright as an Unpainted Starlink Space-based internet service is poised to revolutionize the internet and bring high-speed connectivity to countless communities worldwide. Programs like SpaceX’s Starlink paint a picture of a bright future for the citizens of the world. Like many revolutionary technological advances, there is a […]
Astronomers dissect the anatomy of planetary nebulae using Hubble Space Telescope images Images of two iconic planetary nebulae taken by the Hubble Space Telescope are revealing new information about how they develop their dramatic features. Researchers from Rochester Institute of Technology and Green Bank Observatory presented new findings about the Butterfly Nebula (NGC 6302) and […]
NASA explores solar wind with new view of small sun structures Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun’s flow of high-speed solar wind, detailed in new research published today in The Astrophysical Journal. This first look at relatively small features, dubbed […]
This is a Simulation of the Interstellar Medium Flowing Like Smoke Throughout the Milky Way How do stars form? We know they form from massive structures called molecular clouds, which themselves form from the Interstellar Medium (ISM). But how and why do certain types of stars form? Why, in some situations, does a star like […]
What Happens to Their Supermassive Black Holes When Galaxies Collide? What’s better than two gigantic galaxies swirling into one another until they collide? How about three galaxies swirling into one another until they collide – and they all have supermassive black holes at their core to boot! Recently, a team led by Dr. Adi Foord […]
The Solar Wind is More Attracted to the Earth’s North Pole Than the South. Why? Likely the most well-known result of the Earth’s magnetic field are the Aurora Borealis and Australis (Northern and Southern Lights). When chargers particles from the solar wind run into the Earth’s magnetic field, they can occasionally elicit spectacular light displays. […]
Researchers discover the earliest supermassive black hole and quasar in the universe Nearly every galaxy hosts a monster at its center—a supermassive black hole millions to billions times the size of the Sun. While there’s still much to learn about these objects, many scientists believe they are crucial to the formation and structure of galaxies. […]
The Magnetic Fields Swirling Within the Whirlpool Galaxy Messier objects are some of the most imaged objects in the universe. In part that’s because many of them are so visibly appealing. A good example of that is the Whirlpool galaxy, M51, which recently received an even more dramatic visual representation with a new photo released […]
The First Cubesat With a Hall-Effect Thruster has Gone to Space Student-led teams aren’t the only ones testing out novel electric propulsion techniques recently. Back in November, a company called Exotrail successfully tested a completely new kind of electric propulsion system in space – a small hall-effect thruster. Hall effect thrusters themselves have been around […]
Planets are Finally Being Discovered Orbiting Farther From Their Stars We don’t know much about exoplanets with long orbital periods, but we’re starting to learn.
