Astronomers have identified 18 extreme mass-ratio binaries in a neighboring galaxy called the Large Magellanic Cloud, pictured here. The more massive stars weigh 6 to 16 times as much as the Sun, while the less massive stars weigh about 1 to 2 times the Sun. We’ve caught them “in the delivery room,” since one star

This is a radio image of a very young binary star system, less than about 1 million years old, that formed within a dense core (oval outline) in the Perseus molecular cloud. All stars likely form as binaries within dense cores. Credit: SCUBA-2 survey image by Sarah Sadavoy, CfA Did our sun have a twin

Here’s an illustration of Echeclus, which UCF researcher Gal Sarid and USF professor Maria Womack are studying.

They strive for all of these pieces to fit together, but sometimes finding the unexpected is even more exciting. That’s what happened to University

The image shows the X-ray and H-alpha arcs, as well as the radio

The Little Cub galaxy (circled) which is being stripped of gas by its larger neighbor. Credit: SDSS Collaboration A primitive galaxy that could provide clues about the early Universe has been spotted by astronomers as it begins to be consumed by a gigantic neighbouring galaxy. The Little Cub galaxy — so called because it sits

Image of the sun in 171 angstrom as seen by NASA’s SDO on 3rd July 2017. This channel is especially good at showing coronal loops – the arcs extending off of the Sun where plasma moves along magnetic field lines. The brightest spots seen here are locations where the magnetic field near the surface is

This is an artist’s impression of HD189733b, showing the planet’s atmosphere being stripped by the radiation from its parent star.

Models developed for our own Sun have now been

Astronomers using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) have discovered new details that are helping them decipher the mystery of how giant radio-emitting structures are

Visualizations of the simulated distributions of gas and stars in the Universe from data provided by Cosmowebportal: The cube represents a space section of the Universe (more than 300 million light years), the bright spots on the cube faces show galaxies and galaxy clusters along the cosmic web. The first two disks zoom into the

Earth observation of the space environment taken during a night pass by Dr. Kjell Lindgren of the Expedition 44 crew during Scott Kelly’s One-Year Mission aboard the International Space Station (ISS). An aurora with purple and SSRMS arm are visible. Credit: NASA In each life a little rain must fall, but in space, one of
