Smallest star ever discovered. Very small and dim stars are the best possible candidates for detecting Earth-sized planets which can have liquid water on their surfaces. Credit: Amanda Smith The smallest star yet measured has been discovered by a team of astronomers led by the University of Cambridge. With a size just a sliver larger

his enhanced-color image of Jupiter’s Great Red Spot was created by citizen scientist Jason Major using data from the JunoCam imager on NASA’s Juno spacecraft. The image was taken on July 10, 2017 at 07:10 p.m. PDT (10:10 p.m. EDT), as the Juno spacecraft performed its 7th close flyby of Jupiter. At the time the

Will another planet be added to the list of Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune in our Solar System? Credit: NASA Last year, the existence of an unknown planet in our Solar system was announced. However, this hypothesis was subsequently called into question as biases in the observational data were detected. Now

On Thursday 6 July Scholz will present

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 the planet’s position within its orbit and the inclination of the orbit with respect to the

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 is thought that the supernova explosion was not symmetric, causing the remnant to recoil at around

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
