Solar system formation in two steps

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 […]

Rocks show Mars once felt like Iceland

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

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 […]

Fornax A galaxy investigated with AstroSat

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

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 […]

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

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

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 […]

The Magnetic Fields Swirling Within the Whirlpool Galaxy

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

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 […]
