Using new observations from the James Webb Space Telescope (JWST), astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. Published in the journal Nature, ...
To take a census of nearby cosmic objects, sending out a survey won't work. Scientists need to use many telescopes with different specializations to chart what is in the general neighborhood of the sun.
From house plants and gardens to fields and forests, green is the color we most associate with surface life on Earth, where conditions favored the evolution of organisms that perform oxygen-producing photosynthesis using ...
The birth of stars is a chaotic and dynamic process, especially in the early phase, which is characterized by complex gas structures in the form of spirals and streamers. Such structures are termed "feeding filaments" because ...
It takes two to tango, but in the case of brown dwarfs that were once paired as binary systems, that relationship doesn't last for very long, according to a recent survey from NASA's Hubble Space Telescope.
Astronomers have performed multi-wavelength photometric observations of a nearby planetary-mass object known as SIMP J013656.5+093347. Results of the observational campaign, presented February 22 on the pre-print server arXiv, ...
While analyzing the data from the Next Generation Transit Survey (NGTS), an international team of astronomers has discovered a new brown dwarf. The newfound object, designated NGTS-28Ab, orbits its host star in just about ...
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 ...
