Our galaxy could have 100 billion brown dwarfs or more, according to work by an international team of astronomers, led by Koraljka Muzic from the University of Lisbon and Aleks...
A hot Jupiter at various phases of its orbit. The sizes of the star and planet and the separations between them are to scale for a typical hot Jupiter. The amount of reflected starlight that is observed depends on...
Sketch of the nebula formed by a wind of electrons and positrons coming from the pulsar, and the interaction with interstellar gas. Geminga crossed the plane of the Galaxy (off to the bottom right) around 100,000 years ago. It...
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...
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...

A primitive galaxy that could provide clues about the early Universe has been spotted by astronomers as it begins to be consumed by...
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...
This is an artist's impression of HD189733b, showing the planet's atmosphere being stripped by the radiation from its parent star.
