A study recently submitted to The Astronomical Journal continues to search for the elusive Planet Nine (also called Planet X), which is a hypothetical planet that potentially orbits in the outer reaches of the solar system ...
Using the James Webb Space Telescope (JWST), astronomers have observed a nearby cold brown dwarf designated WISEPA J182831.08+265037.8 (or WISE 1828 for short). The observations delivered important insights into the composition ...
In our most basic understanding of our solar system, planets are drawn into the orbit of our massive star, the sun. But what happens to planet-sized objects that don't have a star? A team of astronomers studying Jupiter-mass ...
An international team of astronomers reports the discovery of a new cataclysmic variable. The newfound system, designated SRGeJ041130.3+685350 (or SRGeJ0411 for short), has an orbital period of about 100 minutes and may contain ...
Astronomers using NASA's James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. ...
Universe Today has examined the potential for sending humans to Jupiter's icy moon, Europa, the planet Venus, and Saturn's largest moon, Titan, all despite their respective harsh environments and vast distances. These conversations ...
Brown dwarfs are sometimes called failed stars, since they form like stars through gravitational collapse, but never gain enough mass to ignite nuclear fusion. The smallest brown dwarfs can overlap in mass with giant planets. ...
EU researchers expect unprecedented insights into galaxies from the study of a mysterious energy force.
University of California, Santa Cruz Professor of Planetary Sciences Francis Nimmo recently co-authored a Science Advances paper about the internal structure of the dwarf planet Eris.
The ESA's Gaia Observatory continues its astrometry mission, which consists of measuring the positions, distances, and motions of stars (and the positions of orbiting exoplanets) with unprecedented precision. Launched in ...
